People often consider features like output power rating, charge controller type, weight/portability, charging rate, and battery type when buying solar generators. But what truly makes a solar generator stand out is its battery capacity.

Our Top Picks

The battery capacity of solar-powered generators is at the heart of their performance. The higher the battery capacity of a solar-powered generator, the longer it can power your appliances. Of course, there would be no point using solar-powered generators if they can only power your appliances for short periods.

The output rating of a solar power generator depends on the size of the inverter it comes with. The larger the size of the inverter, the higher the output power rating. Solar generators with higher power output ratings can be used with appliances with higher power consumption (such as an air conditioner).

The charge controller of a solar-powered generator plays a part in determining charging efficiency. There are two main options in the world of charge controllers: Pulse Width Modulation (PWM) or Maximum Power Point Tracking (MPPT). Of both options, generators that come with MPPT charge controllers offer more efficient solar charging. MPPT controllers draw out as much power from the panels, so the charging rate is faster, and the current flows more effectively.

Portable solar generators can easily be moved. So, whether you decide to take them camping, use them in your house, or use them in an RV, you will not have to break a sweat carrying them.

The two most common types of batteries used in solar generators are lead-acid batteries and lithium batteries. Of both options, lithium batteries have longer lifespans and higher charge densities. But you will most likely spend less on a generator with a lead-acid battery.

Our Best Solar Generators Review

N E X P O W Portable Power Station

About the Product

Thanks to its relatively high battery capacity, the N E X P O W Power Station takes the number one spot amongst our best solar generators. However, this generator is more than just that.

Best Solar GeneratorOur Review

The Capacity of the Battery

The NEXPOW generator features a battery with a capacity of up to 296 Wh – the highest offered by any of the solar generators we examined. Only the Aeiusny, the EF ECOFLOW, and the Baldr come close to the capacity of the NEXPOW.

Going by the capacity of the NEXPOW generator’s battery, it can run a 30-watt device for over 9 hours when fully charged.

Weight/Portability

Weighing in at around 7.05 pounds, the NEXPOW generator is far from being the lightest solar generator on the list. But you should have no issues lifting a 7-pound generator and carrying it around. Still, if you prefer something lighter and more portable, check out the Marbero and the FF Flashfish 300W portable solar generators.

Output Wattage

This solar generator uses a pure sine wave inverter. So, you can safely use electronic devices like CPAP machines, refrigerators, TVs, and other similar sensitive appliances. Then again, you can expect more efficiency in converting DC to AC and less noise.

The NEXPOW has a continuous power output rating of 300W. But this output can surge up to 500W. Considering how much power the inverter of this solar generator gives off, it can power devices like a mini-TV, a mini fan, a CPAP, mobile devices, and much more. For electronic devices with higher power consumption, the EF ECOFLOW or the Aeiusny may be better options.

Featuring a lithium-ion battery, it is no surprise that the NEXPOW is not a heavy one. But beyond being light, if you use this portable generator properly, you will not have to replace the battery in a long time.

This product does not come with a solar panel. So, if you want to make it a true solar power generator, you should get a solar panel for it. Generally, it is recommended that you opt for solar panels with a wattage between 60 and 120 watts.

Charging Rate

Under optimal conditions, the NEXPOW should be fully charged within 9 to 12 hours using solar energy. Plus, you may also charge your car or your home electricity if there is no power outage.

The manufacturer did not indicate the type of charge controller that gives this solar generator power. But considering the relatively long charging time, it is unlikely to be an MPPT controller.

Pro

  • None of the other solar-powered generators have batteries with a capacity as high as this product.
  • Comes with a pure sine wave inverter. So, DC to AC conversion is efficient, and the generator is suitable for sensitive electronics.
  • Like every other solar generator in the review, it uses a lithium-ion battery. So, you will not need a replacement so soon.

Cons

  • The charging rate could be faster.

EF ECOFLOW Portable Power Station

About the Product

Next on our best solar generator list is the EF ECOFLOW. This product boasts one of the highest battery capacities of any of the solar generators we reviewed. But what puts it above the others with similar capacities is its output power.

Overall, this is one to consider for your camping electricity needs.

EF ECOFLOW Portable Power StationOur Review

The Capacity of the Battery

The EF ECOFLOW comes with a battery with a capacity rating of 288 Wh – the same as what the Aeiusny and Baldr solar generators offer. If you were to power a 30-watt device with the EF ECOFLOW, you would get at least 9 hours of run time.

While the capacity of the battery of the EF ECOFLOW is on par with those of the Aeiusny and the Baldr, its output power trumps theirs.

Output Wattage

With the EF ECOFLOW, you can expect a constant output wattage of 600 watts, rising to 1200 watts during surges. None of the other products in our solar generator reviews has an output as high as this. This makes EF ECOFLOW one of the most powerful solar generators in the market.

While the EF ECOFLOW offers a high output wattage, the manufacturer advises against using it with appliances like air conditioners, refrigerators, and heaters. But it works fine with electric kettles, televisions, mini-refrigerators, mobile devices, amongst others.

On the bright side, the EF ECOFLOW comes with 3 AC outlets, each offering 600 watts. And each one of these outlets is connected to a pure sine wave inverter. Like all pure sine wave inverters, you can expect that your electronic devices will not generate significant electrical noise while they run. Also, there is a lower risk of electrical damages to your appliances, thanks to the inverter.

Weight/Portability

One thing we do not really fancy about the EF ECOFLOW is its weight. The EF ECOFLOW solar generator weighs around 11 pounds – none of the other solar generators come close. So, it may not be the best option when you consider portability.

Charging Rate

Under optimal solar energy production from the sun, a 200-watt solar panel will fully charge the EF ECOFLOW portable generator within 1.6 to 3 hours. One of the fastest charging rates of any product on our best solar generator review. This rapidness in charging is less surprising when you consider that this product comes with an inbuilt MPPT charge controller.

Other Features

The EF ECOFLOW generator comes with a lithium-ion battery like the other solar generators. So, it gets extra points for battery longevity and charge density. Then it has a feature that allows you to connect an extra battery and double the capacity from 288 Wh to 576 Wh. Of course, you will have to pay for the extra battery.

The extra battery is a really remarkable feature. With 576 Wh, choosing between energy from solar panels and gas-powered generators is clearer.

Pros

  • Battery capacity is awe-inspiring – only the NEXPOW generator does better on that front.
  • The output wattage is the highest of any of our best solar generators.
  • The charging rate is awe-inspiring – no surprise, it comes with a built-in MPPT charge controller.
  • You can double the capacity of the battery by buying the extra battery kit.
  • Offers multiple AC outlets.

Cons

  • This solar generator is the heaviest of any of the products we reviewed.

Aeiusny Portable Solar Generator 500W

About the Product

Like the EF ECOFLOW, the capacity of the battery of the Aeiusny solar generator is one of the highest of any of the solar generators in our review. But relative to the EF ECOFLOW, its output power falls just short.

Aeiusny Portable Solar Generator 500WOur Review

The Capacity of the Battery

As with the EF ECOFLOW and the Baldr solar generators, the Aeiusny offers a battery power capacity of 288Wh. Albeit pretty high, the NEXPOW offers more power. You will get around 9 hours of use when you connect a 30-watt appliance to the Aeiusny generator at full charge.

Output Wattage

While they have matching capacities, the EF ECOFLOW offers more output power than the Aeiusny solar generator. However, the Aeiusny is not far off. It offers an output wattage of 500 watts, and it can power devices like mini-refrigerators, CPAP machines, drones, and many other small home appliances. However, you should not use this solar generator with heaters, microwave ovens, toasters, hairdryers, rice cookers, and other electronics with power needs over 500 watts.

The Aeiusny generator uses a pure sine wave output. Therefore, it is pretty safe for most of your home appliances, even the sensitive ones. Then again, your electronics will produce little or no noise and work more efficiently with a pure sine wave AC output ports.

Besides the safety of the pure sine wave output ports, the Aeiusny solar generator features multiple protection functions. So, all in all, it is primed for safety.

Weight/Portability

Weighing around 7.05 pounds, the Aeiusny generator is not the most portable solar power generator in our review. But lifting a 7-pound size solar generator is never going to be too much work.

Charging Rate

We believe the charging time of the Aeiusny generator could be better. A compatible solar panel (60 watts) and optimal sunlight take about 8-12 hours to get a full charge. Knowing the EF ECOFLOW only takes around 3 hours or less to charge, the charging rate of the Aeiusny could be way better than what it is.

Besides charging with solar panels, you may also charge the Aeiusny with an AC wall charger, a carport, and gas-powered generators.

Like the others, Aeiusny uses lithium cells. So, the battery is primed for a long lifespan, and it should hold more charge than a lead-acid battery can.

Other Features

We were impressed by the UPS-like feature of the Aeiusny generator. This feature makes this product the perfect backup power: it automatically comes on whenever there is a power outage.

Then again, you get 3 AC outlets, 4 USB ports, and 4 DC ports with this product. If you ever have to use multiple devices on it simultaneously, we reckon you would not find that hard to achieve.

Pros

  • The battery has an impressive capacity – only the battery of the NEXPOW generator does better.
  • Output wattage is impressive – more than what the NEXPOW generator offers but not high as what the EF ECOFLOW offers.
  • Ensures uninterrupted power supply by automatically coming on during power outages.
  • It comes with multiple ports to accommodate up to 11 appliances at a go.

Cons

  • The charging rate could be better – the EF ECOFLOW charges in ¼ of the time it takes the Aeiusny to charge.

BALDR Portable Power Station

About the Product

Alongside the Aeiusny and the EF ECOFLOW, the BALDR offers our best solar generators the second-highest capacity.

BALDR Portable Power StationOur Review

The Capacity of the Battery

On par with the Aeiusny and the EF ECOFLOW, the battery of the BALDR has a capacity of 288 watt-hours. But of course, the NEXPOW still triumphs with its 296 watt-hours capacity.

Like the Aeiusny and the EF ECOFLOW, the battery of the BALDR generator should power a 30-watt appliance for up to 9 hours when fully charge.

Output Wattage

The output power of the BALDR is not very impressive. But it trumps what you can get with the NEXPOW solar generator. The BALDR offers a continuous power production of 330 watts, while the NEXPOW generator only offers 300 watts.

With how much power the BALDR generator offers, it can serve as a power source for cell phones, cameras, laptops, holiday lights, mini coolers, and much more.

However, it may not be the best if you operate appliances with larger power needs. For one, you should not use a microwave oven or a refrigerator with this generator.

The BALDR generator is also a pure sine wave generator. So, expect little noise, smooth charging, and more efficiency. Also, since the chances of heat buildup are pretty low, your devices should be safe when connected to this solar generator.

There is more to look forward to on the safety front as the BALDR comes with multiple circuit/battery management protection systems. It features overcharging protection, low- & high-temperature detectors, over & under current control, overcurrent protection, overload protection, short circuit protection, and many more.

Weight/Portability

The BALDR solar generator weighs just around 7.1 pounds. While this is not very heavy, it is not the lightest amongst the solar generators we reviewed. Nonetheless, it qualifies as a portable solar generator, and you would not break a sweat trying to move it around.

Charging Rate

When connected to a 120 W solar panel, the BALDR generator is estimated to charge fully within 5 to 8 hours in optimal sunlight. This charging rate is not the fastest we saw amongst the review solar generators, but it is pretty decent. Knowing that it comes with an MPPT charge controller, rapid charging is expected.

Besides using solar panels, you may also charge this solar generator through a wall outlet and a car outlet. But note, of these two options, the wall outlet is faster – on par with charging with solar panels.

You may use the BALDR solar generator while you charge it. The upside to doing this is that if there is a power outage, your devices will experience no disruption. In other words, if you want this product to be an emergency power, you could just use it while it charges. Of course, doing this will not deplete stored energy under normal circumstances since the generator is charging.

Other Features

As with the other solar generators, the BALDR uses a lithium battery, so expect long battery life. It also features 1 AC outlet, 3 USB ports (USB 3.0), 1 Type-C USB port, Wireless charging, 2 DC ports, and 1 cigarette lighter.

While this solar generator does not offer as many AC outlets as the Aeiusny and the EF ECOFLOW generators, it offers more port diversity.

Pros

  • Impressive battery – the capacity is really remarkable. However, it holds slightly less charge than the NEXPOW generator.
  • Offers multiple ports, including a wireless charging feature – the only product with this feature.
  • The charging rate is decent – although the EF ECOFLOW charges faster.
  • It is designed with multiple battery protection features, apart from the fact the inverter is a pure sine wave.

Cons

  • If the output wattage were higher, it would support household appliances with higher power needs.

ALLWEI Portable Power Station

About the Product

The ALLWEI generator offers a decent output wattage, and while its battery may not offer the highest capacity, it is still one to try out.

ALLWEI Portable Power StationOur Review

The Capacity of the Battery

With the ALLWEI generator, the battery has an energy storage capacity of 280 watt-hours. While the NEXPOW, the EF ECOFLOW, the Aeiusny, and the Baldr solar generators offer higher capacities, the ALLWEI is still very impressive.

Using the same instance we have been using from the start, the ALLWEI offers over 9 hours of run time for a 30-watt device – about the same as the solar-powered generators with higher capacities.

Output Wattage

On the output wattage front, the ALLWEI solar generator offers a rated continuous power of up to 300 watts – on par with NEXPOW but less than EF ECOFLOW. But this wattage peaks at 600 watts.

The ALLWEI can power cell phones, laptops, 32-inch TVs, mini-refrigerators, and other small household appliances with the said output. But if you need a solar generator that gives off more power, consider the EF CEOFLOW or the Aeiusny.

Like the other products in our best solar generator review, the AC outlets of the ALLWEI generator are pure sine wave. This means less noise, more efficiency, and more safety.

Still, the ALLWEI offers multiple protection features on safety, including overload protection, overcharge protection, over-voltage protection, and overheating protection. This should give you more confidence in the battery life of this generator. Plus, if you consider that it comes with a lithium battery, you will not need a replacement so soon.

Weight/Portability

The ALLWEI weighs 8.33 pounds – the second-heaviest on our list. Of course, for this kind of device, anyone would prefer something lighter. But moving an 8.33-pound solar generator should be no problem.

Charging Rate

The ALLWEI solar generator has a pretty decent charging rate, but it could be better. When connected to 80W solar panels under optimal conditions, you should get a full charge in 7-8 hours.

While this charging rate is not the fastest we came across in our review, it is still fair. Of course, the ALLWEI generator comes with an inbuilt MPPT, so this relatively rapid charging rate is expected. Still, we believe it could be faster.

When you are not charging the ALLWEI with solar panels, you may charge it with a wall charger, car charger, or generator. These other 3 options are rated to charge faster than 80W solar panels.

Other Features

The ALLWEI solar generator comes with 2 AC outlets, 2 USB ports, 3 DC ports, 1 cigarette lighter port, and 1 Type-C port. Not as diverse as what you would get with the BALDR generator but still good enough.

Pros

  • The energy storage capacity of the battery of this product is excellent – not as high as what NEXPOW offers. Still, it should serve you well.
  • The charging rate is decent – one of the highest on the list. However, the EF ECOFLOW still offers the fastest charging rate.
  • It comes with multiple ports, making it easier to use various types of electronic devices.
  • Features multiple protection features and pure sine wave AC outlets for reinforced battery safety.

Cons

  • There are lighter options (such as the Marbero solar generator) available.
  • It would have been much more desirable with a higher base output power.

ROCKPALS 300W Portable Power Station

About the Product

The performance of the ROCKPALS portable solar generator mirrors that of the ALLWEI generator. But one noticeable difference between both products is their weight.

ROCKPALS 300W Portable Power StationOur Review

The Capacity of the Battery

The battery of the ROCKPALS generator offers a storage capacity of around 280-watt hours – the same as the ALLWEI. This capacity may not be as high as the NEXPOW, EF ECOFLOW, or the Aeiusny offer. But following a full charge, you can get at least 9 hours for a 30-watt appliance with this generator.

Output Wattage

The ROCKPALS generator offers an output power of 300 watts with a peak power of 500 watts. This output is about the same as what the NEXPOW generator offers but far below the EF ECOFLOW offers.

The output of the ROCKPALS generator suffices for mini car refrigerators, mobile phones, laptops, CPAP machines, and other household appliances with power requirements below 300 watts. However, it may not suit high-power consumers such as microwave ovens, coffee makers, and toasters.

As with the others, the AC outlets of the ROCKPALS generator are pure sine waves. So, you can rest assured that the output electricity is stable, relatively safer, and will generate less electrical noise.

This product does not fall behind on safety. The battery management system prolongs battery life by protecting against overload, short circuits, overvoltage, overcurrent, and overheating. Then since the battery is the lithium type, the odds are in favor of long battery life.

Weight/Portability

The ROCKPALS solar generator weighs about 7.7 pounds – not the lightest we have on the list but still light enough for portability.

Charging Rate

The ROCKPALS comes with an inbuilt MPPT controller. So, we were not too surprised when we found out that this generator charges fully in 5 to 7 hours when connected to 100 W solar panels. This rate is not as fast as the EF ECOFLOW generator, but it is still impressive. We reckon the charging time could be lower with additional solar panels.

Note that this product does not come with a solar panel. You have to get that separately.

If you cannot charge the ROCKPALS generator with a solar panel, you may charge it with a car charger, a wall outlet, USB-C power delivery, or a wall outlet + USB-C power delivery.

Other Features

This solar generator comes with 2 USB outlets, 1 USB-C port, 1 USB 3.0 port, 1 AC outlet, 1 cigarette lighter port, and 2 DC outlets. In total, you get 8 ports, which support various types of devices.

Pros

  • The battery’s capacity is pretty high – it stores just a little less energy than the NEXPOW generator.
  • Crafted with an MPPT controller, the ROCKPALS generator charges pretty fast with solar panels. But the EF ECOFLOW still takes the lead when it comes to charging rates.
  • Features multiple output ports.
  • The battery management system and the pure sine wave AC dock optimize the battery for stability and safety.

Cons

  • The output power could be higher to allow support for appliances with higher power requirements.

Jackery Portable Power Station Explorer 240

About the Product

While the energy storage capacity of the Jackery generator falls below what the NEXPOW, EF ECOFLOW, and Aeiusny solar generators offer, it still does enough to earn its place as a decent backup power source.

Jackery Portable Power Station Explorer 240Our Review

The Capacity of the Battery

The Jackery generator offers a battery storage capacity of 240 Wh – far from what the NEXPOW and the EF ECOFLOW offer. But using our 30-watt appliance analogy, it should be able to run for 8 hours when fully charge—just around 1 hour less than what the NEXPOW and EF ECOFLOW solar power generators offer.

Output Wattage

The Jackery generator has a rated output wattage of 200 watts – only the Marbero solar generator offers lower electrical power. Nonetheless, this output should suffice for mobile devices, cooling fans, drones, lamps, and laptops. But you may not use it to power an electric grill, a refrigerator, a microwave, a blender, or any other appliance with input power above 200 watts.

The AC outlet that comes with the Jackery generator is a pure sine wave. This means the output is stable, safe, and efficient. But the safety mechanisms of this solar generator do not end there. The Jackery generator features multiple protective solar generator technology, including protection against overload, overcurrent, short circuit, overcharging, temperature extremes, overvoltage, and over-discharge.

Weight/Portability

The Jackery solar generator weighs 6.83 pounds, making it one of the 3 lightest generators in our review. Of course, if you want something lighter, you can always consider the FF Flashfish 300 W or the Marbero generator.

Charging Rate

With a 60-watt solar panel and optimal solar energy from the sun, the Jackery typically charges fully in 5.5 hours – the closest charging rate to what the EF ECOFLOW offers. Of course, it comes with an inbuilt MPPT controller, hence the rapid charging time.

For fasting charging times, you may charge it with a wall outlet or a car charger.

Other Features

The Jackery Explorer 240 comes with 2 USB outlets, 1 AC port, and 1 car outlet. We believe the ports of this product could be more diverse. For one, having a Type-C USB outlet would have been nice.

Pros

  • The charging rate is pretty impressive – only the EF ECOFLOW charges faster.
  • It is pretty lightweight – only the FF Flasfish 300W and the Marbero weigh less.
  • Features multiple protection systems, including a pure sine wave AC port.

Cons

  • The ports could be more diverse.

FF Flashfish 300W Solar Generator

About the Product

The FF Flashfish 300W Solar Generator gets top marks for its portability. But only is it very lightweight, it also offers a decent power output, the battery capacity is okay, and it comes with a multifunction battery management system.

FF Flashfish 300W Solar GeneratorOur Review

The Capacity of the Battery

The FF Flashfish 300W Solar Generator comes with 3 lithium-ion batteries, and each battery has a rated capacity of 74 Wh. So, in total, you get a capacity of around 222 Wh with this generator. Undoubtedly, this falls way below what the NEXPOW generator offers, but it would do just fine, nonetheless.

To put things in perspective, with a 222 Wh capacity, you can power a 22-watt device for over 10 hours with this solar generator.

Weight/Portability

The FF Flashfish 300W Solar Generator might not be the most portable solar generator on the list. However, its lightness cannot be denied. Weighing in at around 5.6 pounds, this solar generator is only heavier than the Marbero 88Wh. So, you should have no trouble moving it around.

Output Wattage

The FF Flashfish 300W Solar Generator has a base power output rating of around 300 watts and a surge power of 350 watts. This power output is not very impressive. But it should work just fine for a 55 W mini freezer, mobile devices, drones, a mini fan, and some light bulbs.

You may try out the EF ECOFLOW or the Aeiusny portable solar generators if you want to power appliances with higher power consumption. These 3 alternatives offer higher power output than the FF Flashfish 300W.

On a brighter note, the FF Flashfish 300W uses a pure sine wave inverter. So, it works just fine with electronics like CPAP machines, freezers, refrigerators, and TVs. Also, since the inverter is a pure sine wave, the FF Flashfish 300W is relatively noiseless and more efficient.

The FF Flashfish 300W uses a lithium battery, and this contributes to its lightness. Then again, lithium batteries are primed to last long, and they hold more charge per cell.

Charging Rate

When plugged into solar panels with wattages between 50 and 60 watts, the battery of the FF Flashfish 300W is expected to charge fully within 6 to 7 hours. But, of course, this charging rate is only expected in optimal conditions. If you do not get enough sun or do not shine for too long, the solar panel may not get enough solar energy to charge the battery in 7 hours.

Note that this product does not come with a solar panel. If you choose to charge it using solar panels, you have to buy one separately. Alternatively, you may charge the battery with your car or with the electricity in your home. Of course, using either of these options defeats the essence of solar power.

While we fancy the capacity and batteries of the FF Flashfish 300W offer, the absence of an MPPT charge controller in the setup is disappointing. This solar generator would have charged more efficiently if it had been built with an MPPT controller.

Pros

    • The capacity of the batteries may fall short of what the NEXPOW generator offers, but you would still be able to go hours using this to power your devices.
    • This generator uses lithium-ion batteries. So, it is primed to last long and relatively more charge.
    • With a pure sine wave inverter, this generator is efficient, and its operation is noiseless. That aside, being a pure sine wave makes a worthy option for delicate appliances.
    • It is the second-lightest in our solar generator reviews, just behind the Marbero solar generator.

Cons

  • The output power could be higher.
  • Charging would have been better with an MPPT charge controller.

Marbero 88Wh Portable Power Station

About the Product

While it may not offer the highest capacity or output power, the Marbero 88Wh is the lightest of all the solar generators we reviewed. It also has the smallest dimensions, making it the most portable.

Marbero 88Wh Portable Power StationOur Review

The Capacity of the Battery

As revealed by its name, the Marbero 88Wh has an energy storage capacity of 88 Wh – the lowest of any generators on our list. If you connected a 30-watt device to it, it would run for slightly less than 3 hours.

Output Wattage

The Marbero 88Wh offers a running power of 80 watts and a peak power of 120 watts – the lowest of all the products in our review. With this output, the best use for this solar generator is as a camping power source.

The Marbero 88Wh would work fine with mobile phones, tablets, laptops, cameras, mini fans, and similar low-power appliances.

Unlike the other solar generators, the AC ports of the Marbero 88Wh are modified sine waves. So, they are unsuitable for delicate electronics like CPAP machines. Also, you may sense electrical noises from the devices you connect to this generator.

On the bright side, the battery management system offers multiple safety features to keep the battery in good shape. It offers protection against overload, short circuit, overvoltage, high temperature, and much more.

Weight/Portability

If getting a very portable backup power is your priority, we reckon you would fancy the Marbero 88Wh. It weighs just 2.4 pounds – at least 100% lighter than the next lightest solar generator in our review. The Marbero 88Wh can fit in your backpack.

Charging Rate

It is estimated that under optimal conditions and with a compatible solar panel, the Marbero 88Wh charges fully in 5 hours. This might seem fast until you remember its charging capacity is relatively low. If you would rather go with a generator that charges faster, the EF ECOFLOW is an option to consider.

When not charging the Marbero 88Wh with a solar panel, you may charge it with AC power from a wall outlet using the provided adapter. The charging time of the Marbero 88Wh with AC power and solar panels is about the same.

Other Features

The Marbero 88Wh has two AC ports (a 2-prong port and a 3-prong port). Besides that, it has 2 USB 3.0 ports, 2 USB outlets, 1 USB Type-C port, and 1 DC-port.

Pros

    • None of the other products is as portable or as light as this one.
    • The charging time is decent – not as fast as the EF ECOFLOW, but it is decent.
    • Offers multiple ports and enough port diversity.

Cons

  • The AC output power is modified sine wave, so this generator is not okay with sensitive electronics.

Buying Guide For Solar-Powered Generators

Features to Look Out For

Battery Capacity

The capacity of the battery of a solar generator tells you how much energy it can store. The higher the capacity, the higher the energy the battery can store. At the same time, the more energy the battery stores, the longer it can power your battery.

When selecting a solar generator, pay close attention to the capacity and compare it with the input power of the devices you intend to connect to it.

For instance, if you opt for a solar generator whose capacity is 600Wh, and the input power of the device you intend to connect to it is 40W, you can expect a run time of up to 15 hours (600÷40). You can easily estimate how long the battery will power your devices following a full charge by doing this quick calculation.

Output Power Rating

The output power rating of solar generators defines the limit of the types of devices a solar generator can power. For instance, if a solar generator has a maximum output wattage of 500W, you should not connect any device with a power rating over 500 watts to it. Doing so will damage the generator.

Going by the above, the output power of the solar generator you choose will depend on the device with the highest input power rating amongst your appliances.

Besides checking the continuous/running power, you should also note the peak/surge power. Appliances like refrigerators typically need a surge of power at the start.

The starting power of devices like a refrigerator should not surpass your generator’s surge/peak power. If it does, the device may damage the generator.

Besides checking out the output wattage, look out for the type of inverter used in the generator. You will get a better experience with a pure sine wave inverter than with other types. This tip also applies when you are making a DIY solar generator and installing a power inverter in your camper.

Charge Controller Type

The type of controller in your solar generator plays a part in the system’s charging rate and charging efficiency. While some use simple charge controllers like PWM, others use MPPT controllers.

For the fastest and most efficient charging, look put for those that come with MPPT charge controllers,

Weight/Portability

If you would be going camping with your solar generator, you definitely want it to be portable enough for easy transportation. Even if you will not be taking the generator camping, everyone loves the ease of a lightweight product.

Charging Rate

Nothing beats having a solar generator that charges very fast and loses charge very slowly. When buying a solar generator, pay close attention to the charging rate. Look out for solar generators that can charge fully within 5-8 hours under optimal sunlight. Anything higher is not desirable, except you live in an area that sees a lot of sunlight.

Battery type

In many cases, solar generators come with lithium batteries. But you may come across those with lead-acid batteries. If you ever have to choose between both types, opt for lithium. Lithium batteries have longer lifespans, higher charge density, and they are relatively safer.

Solar Panels

Solar generators typically do not come with solar panels. So, you may have to get one separately. When you go shopping for solar panels, ensure you get one with a solar input compatible with your solar generator.

Beyond compatibility, you should also pay attention to the cell type of the solar panels. You may have to choose between polycrystalline solar cells and monocrystalline cells. If ever faced with this choice, opt for monocrystalline solar panels.

Monocrystalline solar panels are generally more efficient than polycrystalline solar panels.

For longer run times, your best bet is a solar generator whose battery has a high capacity. But beyond having long run times, ensure the generator’s output power you choose is enough for the types of devices you intend to connect to it.

Also, ensure that the generator charges fully within reasonable times and that you can carry it around easily.
