5 Best Solar Kettles in 2023


When it comes to camping or going off the grid, one common tool that anyone needs is cooking. Necessities such as having the ability to boil water so it is clean to drink are vitally important. A solar kettle can ensure you get tasty meals and that important coffee while enjoying the wilderness. Whatever tool you purchase must be reliable and meet your unique camping needs.

A solar kettle, often called a solar oven, is a portable solar-powered device that can cook hot food and boil hot water, oftentimes to the boiling point. Some solar-powered kettles on the market are strictly powered by the sun, while others have backup energy methods in lithium batteries.

You would consider your needs and geography and determine which would work best for you. These solar kettles can come in various sizes to accommodate different amounts of food and liquid.

Best Solar Kettle Reviews

1. GoSun Fusion Hybrid Solar Oven

Out of all of the portable solar devices on this list, you need to know about the best one first! We considered the need for feeding more than one person at a time, outdoor durability, portability, ability to use with and without the sun’s light, and the ability to boil the liquid.

The GoSun Fusion Solar Oven runs off both solar powers and can run off any 12v power source. Portable and easy to use, this item can cook four to six meals per session and steam, bake, fry, or roast.

This item is the best available if you plan to cook meals during the day and in the dark.


This solar oven is the best solar kettle because this oven holds a larger amount of food and can be used both day and night.

Camping with your family and being able to cook for more than one person at a time is a definite bonus.

Besides, you have the ability to cook your food in several different ways, from way off somewhere great.


Carrying this item may be difficult if hiking into camp since no carrying case comes with this solar cooker.

While this folds up and is portable, you need to consider if this item’s extra fourteen pounds and size would be too awkward for use at a potentially far-out campsite.

2. Solar Kettle Thermal Flask Survival Gear

Sometimes, what you need is something small that is just for you to get the job done. If you aim to use survival skills in the wilderness and have something small and reliable, we have you covered. Here are a few small-capacity solar-powered kettles that can best fit these needs.

You will love this top-of-the-line solar kettle thermal flask survival gear on Amazon for your next hiking or off-grid adventure.

Heating water with this solar kettle takes only 20 minutes. The energy created by the sun’s powerful rays makes this little thermos a portable solar treasure.

This device is designed like a thermos for easy transport for work or outdoor use.

The vacuum-sealed container can hold up to three cups of liquid and reach a boiling point in less than an hour.


This item is extremely easy to carry because it is only a little over two pounds and can easily fit inside a travel or hiking backpack.

This item captures the sun’s rays and can cook in the snow and overcast days. So you will never have to worry about not being able to cook.

The integrated temperature gauge allows you to accurately assess the liquid’s temperature (or solids) inside the thermal flask.

Because of the amazing design, you will never have to worry about burning your fingers with the metal outside the kettle. The sun’s energy is transferred to the inner tube, leaving the outer shell cool.


Because this item is so small, cooking food for more than one person is impossible.

The sun must be out in some capacity for this solar kettle to work properly, and it does not allow for thermal power in the night hours.

3. GoSun Sport Fastest Solar Oven

You will love this GoSun Survival Solar Cooker. This solar cooker has rave reviews on Amazon, and you can quickly and easily tote this around from one location to the next.

One great feature about this cooking device is that it is made of stainless steel, vacuum-sealed, and durable enough to handle the great outdoors.


If you have small children with you, there is always the worry that they will burn little fingers on cooking devices.

This solar cooker is cool and doesn’t pose any fire hazard. It can cook your food in as fast as 20 to 30 minutes with the ability to reach up to and over five hundred and fifty degrees in direct sunlight.

And the best, it is easy to clean! This little sun-powered kettle allows easy cleaning with its stainless steel tube and scrubber brush that comes with the solar device.


Because this item is listed under the best small-capacity solar cookers, it is obvious that this device will not cook more than enough food for two people at most.

These solar kettles do not have a separate carry case, making portability more challenging, especially in an outdoor/camping setting.

Lastly, this little solar device would be even better if there were some temperature gauges, like the GoSun Fusion Solar Oven listed at the top of this review.

4. MrMapMax Solar Oven Portable Oven-4.5L Large Capacity

The thing about the MrMapMax Solar Oven is its size. It’s the perfect solar kettle for large volumes of water. You’d probably want to use it when boiling water for the whole family or a couple of friends. But then, in many cases, you’d probably want to use it for not more than 4 people at a go.

Beyond its impressive capacity, the thermometer that comes with this solar oven makes cooking and boiling water with it more precise. We knew the temperature of the oven with a fair amount of precision. So we could get the water to just about the temperature we needed. We didn’t have to do an empirical temperature check.

Besides that, the thermometer helped ensure the best outcome for the meals we attempted to cook with it. Also, because we could monitor the temperature, we were able to prepare various meals with it without worrying about the ingredients getting ruined by too little or too much heat.

Considering its capacity, we didn’t expect the MrMapMax Solar Oven to be as light as it was. Of course, the lightness impressed us. Its large capacity, alongside not being heavy, meant we could move it around easily. So, for sure, we’d consider it for camping trips.

One drawback of this product is that it takes up much space – more than most of the ovens in this review. Still, that doesn’t dampen its overall quality.


The cooking capacity is large enough to cook or boil water for 2-4 people. It can cook several eggs at a time, boil hot water for tea or hot coffee, or even bake some chicken wings.

This solar cooker is enclosed in a durable, abrasion-resistant case. So, there isn’t much to worry about the oven getting damaged while in transit.

Because of the capacity, you will love that you don’t have to worry about having enough food for everyone simultaneously.

It comes with a temperature gauge, making it suitable for cooking various types of meals.


When looking at solar kettles, this one is a little bit bulky, which overall challenges the point of portability.

5. 4Patriots Sun Kettle XL Solar Water Heater

The 4Patriots Sun Kettle is the option you’ll want to pay attention to if you move alone or in twos. The approximately one-liter capacity will certainly not be of much use for a crowd.

However, the good thing about this relatively small capacity is its portability. You can readily carry this solar kettle around. Of course, portability is surely an advantage when you are not moving in a crowd.

Besides its portability, this solar kettle is pretty durable. We even had an instance where it was dropped while we assessed it, and there was barely any scratch.


It is pretty portable, so you’d probably love having it around while camping outdoors. But this portability comes at the expense of a relatively low volume.

It is fairly scratch-resistant, and the glass does not crack readily.


We think it can offer a little more volume without sacrificing its portability.

Final Thoughts

Overall, you can bring the amazing ability to boil water, coffee, and tea and cook meals that you would normally make at home from the convenience of a device powered by the sun.

Your family, or maybe just you, will be sure to enhance your camping experience with all that the best solar kettle brings to you.
