PEROVAD Pilot X7 20000mAh Power Bank liked, high capacity 20000mah,
Small size, nice when touching. How it will work, how many weeks, months or years. For a long time I wanted to buy such a device as an energy bank, now many devices for which it is necessary to recharge in conditions remote from the mains. I have not yet tried the fastest charge speed with a 3.4 A output as described on the seller's website. But I think that everything will work fine.
