This is the best power bank I have ever had! It is very efficient, charges quickly, and easily allows you to charge multiple devices simultaneously and at different power levels. I use it with a portable, foldable 28W solar panel from BigBlue, which I bought separately online to ensure energy independence—mainly for lighting and charging phones during longer trips, camping, or vacations. Compared to my other power banks, this one gives the best results—when connected to the solar panel, it stores more than twice as much energy as my other batteries! The quality and electronics of this power bank are at a very high level, and the Xstorm brand seems really professional in this field! The price is higher than some competing models, but in my opinion, it is fully justified. The display showing the charging percentage precisely is a huge advantage with such a large capacity device. If I need another power bank in the future—in this size, a smaller one, or another model—I will definitely choose Xstorm! It is worth adding that I found the best price on Military.eu! It’s a great find, tested intensively for three days and it fully lived up to expectations!
