I’m surprised, I bought it to play pokemon go without having to worry about running out of battery, if it’s true that with the game on without saving battery and with the brightness at full, instead of adding it was subtracting, but I was subtracting a 1 at 8-10 minutes instead of a 1 every 3 minutes, something that has surprised me a lot is the led flashlight! I just looked for a mobile phone charger but I did not realize that I had a flashlight (quite powerful for very dark places the truth) and that has made it better! for pokemon go to be able to go by the mountain in search of nocturnal pokemon ! and if you use it to charge the mobile without playing anything it charges very well, the weight is not so much nor the size for me are good, since I take it in the backpack and the cable that I use mine (the one that comes is very short) comes to me from the backpack to the hand or to the pocket without problems. fantastic product !
Advantages: perfect for pokemon go. long lasting battery, led flashlight, 2 charges at once, if used together with backpack, etc. does not bother the size or weight. pleasant to touch.
Disadvantages: it depends on who buys it it can be annoying the size and weight, but it is a battery of 20,000 mah if you want one that weighs less looking for less load, the microusb cable that carries is very very short, but if you look to leave it in a fixed place is worth.
