4Patriots Sun Kettle: Portable Solar Water Heater For Hunting & Emergencies - 16.9 oz Capacity

Great product, but after buying it I saw a large spike in spam from nutter conspiracy theorists, right-wing loonies and get rich quick schemes. I guess the name of the company is a give away given the state of American politics these days. Nevertheless, I recommend the product.

I just received my Sun Kettle XL yesterday and decided to give it a try today. I live in Phoenix so your results may vary from mine.Data:Location: PhoenixMonth: AugustWeather: 95 degrees, sunny not a cloud in the skyTest Time: Started at 12:15pmStarting Water Temp (from faucet): 80 degreesWater Volume: 32 ounces12:15pm - 80 degrees12:45pm - 140 degrees1:15pm - 178 degrees1:45pm - 210 degrees (test stopped)Notes:- Each time when I checked the temperature I checked & adjusted the position of the Sun Kettle.- At the end of the test I checked the water temperature with an instant read thermometer. The Sun Kettle registered 210, the instant read registered 204.After ending the test I resealed the kettle and closed the reflectors. I then left the kettle outside, but not in direct sun. After 2 hours I measured the water temperature with my instant read thermometer and it registered 186 degrees.Conclusions- While I didn't see the water boil I know it was very hot. Hot enough to make instant foods like coffee, hot chocolate, oatmeal or mac & cheese, etc.- The sealed kettle kept the water very hot even after 2 hours.- The kettle, in what I can only imagine as close to ideal circumstances, heated water to the boiling point in about 1.5 hours.- I'm fairly confident if I had more time the water would have boiled.If these are typical results then I'd say I'm very happy with the Sun Kettle XL.If my results vary in the future I'll update this review.

500ミリリットルと有りますが450ミリリットルをお湯に変えることが出来ます。もちろん腫れていることが条件です。腫れて入れば、1時間強でお湯に成ります。開き方はハンドル持ち手を開閉部の上に切り込み刺し込み開閉部を開き固定して日光に当てます。サンケトルの影でちゃんと日に当たっているかを確認出来ます。

I only bought one of these so I could try it out as there were quite a few reviews that stated that it did not heat the water as expected. I placed mine in the sun around 9:00 am. I left it there for about 2.5 hours. Note that it was about 75 degrees when I put it out there. When I went to check on it, it had steam coming out of the vent at the top. I will warn you to be careful when picking the unit up at this point. I touched the palm of my hand to the vent and it was very hot. I did not check the temperature of the water, but when I poured it out in the sink it was steaming. I would recommend this product. If you have more than one person that you intend to use this for, I would get another one. This unit does not hold enough water for more than one or two servings for many freeze dried foods, but its plenty for two or three cups of coffee or tea. I plan to buy one more.

Works as advertised. Also holds heat for a long period of time when solar wings are retracted.
