4Patriots Sun Kettle Portable Solar Water Heater for Hunting and Emergencies, 16.9 Ounce 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.

The design of the carrying handle is neat, and the kit is lightweight enough to be genuinely portable. Getting the top on and off is tricky until one has acquired the knack. Capacity is c 400 ml, if you heed the instructions to leave 2" space at the top for steam. My experience, however, is that even in a couple of hours in early-afternoon sunshine the water temperature rises by not much more than 30 degrees Celsius - has certainly got nowhere near boiling point.

When i received the product everything’s look fine. I wanted to use it, I opened it and the glass inside was broken. The return window is closed now.

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。

Excellent well constructed product. Used this to make sun tea and it got up to temp very quickly in the afternoon sun. Second use was for heating water for some of the patriots dehydrated food and again this fit the bill perfectly to have a nice hot meal at camp with little to no fuss.

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

Soooo excited that it is better than advertised. A relief to have quality like this. A true help to survive. Great value!
