Xtorm Go2 10000 mAh 15W Solar Powerbank - Black

I have one like this. Overall, I'm satisfied. Once, the charge indicator got confused, but after fully discharging the power bank, it works as it should. The capacity, at least by my feelings, is honest. Charging from the solar panel is quite slow, but overall, I wasn't really expecting anything amazing in that regard. The gadget is always with me and overall I recommend it.

Overall, the product is fine, although a few things disappointed me. My other power bank, which has twice the capacity, is similar in size and weight, so this one discharges faster. The solar panel is an interesting solution, but it needs to be directly in the sun to work. My testing shows that it can't be conveniently charged on a backpack, as it easily loses access to light. A full solar charge takes several days, so the panel is rather optional, and it increases the size and weight of the equipment.

I always keep it in the car. On sunny (or just not cloudy) days, I put it in a way that lets it get some extra charge from the sun for free. The torch can be useful, though I rarely use it. I treat solar charging more as a backup, just in case – after all, you’re not constantly using your phone or radio. In my opinion, it’s worth buying.

The power bank is really a great choice – it often saves my phone when I’m not at home. Unfortunately, I don’t recommend solar charging. If you want to use this feature effectively, it’s better to buy an additional solar mat, which I plan to do soon.

I appreciate the light design of this power bank. It's nice that a cable and carabiner are included, and one whole side serves as a torch, which is activated by pressing the power button twice. The manufacturer states that charging from the mains takes 4 hours and the capacity is enough for two full charges of a smartphone. Unfortunately, solar charging is poor – according to the manual, it would take as much as 1000 hours to fully charge it.

I was a bit hesitant to buy it, but this power bank turned out to be fantastic – it performed well during a mountain trip and charged itself in the sun. It’s a solid device, good quality, and meets my expectations. I recommend it, I'm satisfied.

The power bank allows you to charge a smartphone with about a 4000mAh battery twice. Unfortunately, the LED indicator is misleading – after placing it in the sun for several days, it shows a full charge, but once you connect a device it turns out there was only enough power for a few percent. Therefore, the indicator is only useful when charging from a power charger, not for checking the current energy level.
