Advanced Solar Technology

Parabolic mirrors trap the rays of the sun. Then, solar-collection technology focuses the sun’s energy on the tempered-glass tube. Which heats your water to temps as high as 212°F in about 45 minutes, depending on your weather conditions.

Safe & Durable Construction

Advanced engineering makes your Sun Kettle® powerful, efficient and safe.

  1. SOLAR POWERED: Use the free energy of the sun to boil water. No need for batteries or cords.
  2. SAFE: Use your bare hands to touch the Sun Kettle XL because it is made from premium BAS plastic. A ventilated cup also helps prevent dangerous overboils.
  3. KEEPS DRINKS HOT: Close the mirrors to use like a thermos & keep your drinks TOASTY for hours.
  4. BUILT TOUGH: Tempered-glass tube is shatter-resistant to withstand tumbles & bumps.
  5. STABLE ANYWHERE: Square base and kickstand give you 4 points of contact and prevents spilling.

A Cinch to Use — Easy as 1, 2… 3!

You don’t have to be a “gadget guru” to use a Sun Kettle®. It’s so easy to operate, anyone can do it. There are only 3 simple steps:

  1. Fill with liquid
  2. Open panels towards the sunlight
  3. Enjoy hot food, clean water and more — all thanks to the sun

Quiet, Covert & Smoke-Free

Never alert a looter to your location. This solar thermos is silent and requires no flames. The perfect survival device in any off-grid environment.

Compact & Lightweight

Don't let the "XL" fool you. The Sun Kettle XL is foldable and conveniently fits in your bug out bag or backpack. At only 2 ft. tall and 3.7 pounds, it's small enough to pack away and take with you in an emergency. Unlike a heavy stockpot... and the firewood you’d need to heat it.

Works Fast, Even in Cloudy Conditions

Your Sun Kettle® boils water in about 45 minutes, depending on sunlight and temperature conditions. No fuss, no muss. Just fill up your Sun Kettle® XL and let Mother Nature do the rest.

There’s no denying how valuable having a few of these personal water heaters on hand could be. For cooking, purifying drinking water… but you can also use your Sun Kettle® to make all kinds of tasty concoctions!

Customer Reviews: Folks Love This Solar Cooker

It Cooked While We Fished

"It's great if you want to boil water for tea, coffee, or for a freeze-dried lunch. It's ideal for 2 or 3 people… Really simple to set up. You can set it and let it go and not have to worry about tending a fire just to boil some water.

We went fishing for about an hour and a half and left it ‘cooking.’ It's definitely steamy.

You want to enjoy your camping experience, not be constantly worried about cooking. Super cool product. I highly recommend it."

Nice Design but lightweight construction

Be aware this product is designed well on paper but the construction materials result in a somewhat fragile / flimsy item. The product can work well for family camping trips where one 'plays' at survival, but is not suited for actual rugged backpacking conditions where one might accidentally drop it o a hard surface. As a product line improvement I would like to see metal frame construction and polished metal reflectors. Impact plastic will looses its moisture over time becoming brittle, Using actual glass concave mirrors is an invitation for breakage. So need a product sturdy like the old metal thermos bottles; drop it and no worries.



Hi Mike, Thank you for your review and feedback of our Sun Kettle XL Solar Cooker. Best Regards, Kristy B.

This is perfect

This is the best thing to get if you are a pepper. If you are camping or in a situation where you have no electricity, you can boil the water needed for the food, or boil any water to get rid of contaminants. I love this company and the customer service is stellar!! I would give them 100 stars if I could.



Amy, thank you for writing us and for the kind words about our service team. We love that you are happy with your Sun Kettle XL! Best Regards~Mandy

Sun Kettle: 1 hr for Hot Water

I was very pleased with how this system works. It made me wish it came with a bigger capacity! I received this as a "free gift" in a special offer from a social media site. I have ordered from here before but just food for my stores. I had a moment of panic when the Russia/Ukraine conflict occurred and this ad popped up with a super price and add-ons to sweeten the deal. Just in time for my panic attack. I set the Sun Kettle on my counter for about a week, waiting for the sun to re-appear here. It came out this past weekend (FINALLY) but it was chilly outside (about 62 degrees). I put 8 ounces of cool tap water inside and laid this out on our deck table, propped with the kickstand as directed, pointed toward the late afternoon sun. I went about prepping dinner and some other distractions. Mister went out about an hour later to start the grill and reminded me this was outside and the sun was getting low. I brought it inside and poured out the water in to my mug. The water was perfectly HOT for tea! If I had to use this while camping with my freeze-dried coffee, I'd be happy. Now, I didn't fill the Kettle all the way up, so if you do, and use cold spring water, you will have different results. It's not QUICK but it seems reliable. I honestly didn't believe it would work - but it looked pretty impressive. IT WORKED!! I will try an egg in it next!



Thank you for your review, Lisa! We're so happy to hear that the Sun Kettle provided you with hot water for your tea! We do offer the Sun Kettle in a larger size. You can find our Sun Kettle XL here: - If you have any questions, please let us know! Best Regards! ~ Kerri
