I was happy to get the power bank, as the specification promises to charge actual smartphones according to PPS 3.0.
However, compared to my old 20000 mah Anker powerbank, the loading capacity is really poor. It is not able to load two smartphones completely, charging will stop before the second one is full. The four LED are then off. When connecting then the powerpie to a charger, two LEDs are on again, and recharge of the powerpie is appropriately quick. Very often my smartphone is complaining that charger is not connected correctly if powerpie is used.
I think about complaining the unit at all even it is hard to get a proof about maifunction.
I bought the device and after 7 months it broke. I contacted technical support. I followed their instructions. After that, they promised to replace the product with a new one. But they didn't. They do not respond to my mail requests.
I still don't have it, after having ordered it 4 months ago. Shipping has been disastrous, I can't even track it so there's no guarantee that it will arrive, I spent 60$ for nothing. If you really want it, try buying it off Amazon or the EU shop, but be warned, shipping is very bad
Good evening.. the product was purchased and it was very good in use.. even better than the mobile charger inside the box.. but the idea of buying from this site again is not desirable at all.. my shipment continued to arrive by mail inside America for more than a month and a half ...and two weeks later he brought me to a magazine for my residence!! I mean, after two months!! Note that customer service does not respond quickly but ignores the email for a long time!!
Bought this powerbank after seeing so many good reviews, and was not dissapointed.
Fully charged the powerbank under 3 hours for a 20000mah capacity.
Phone charging is also super fast.
Recommended for those who travels frequently, fast charging is the best feature here!
