Please NOTE :
Power bank has two regular standard of capacity , one is the battery capacity, one is the rated capacity. The 10000mah power bank, being labeled 10000mah/3.7v core capacity be converted to rated capacity 6200mah/5v.
Why exist this difference?
The most important reason is the conversion rate. Because most of power bank’s battery voltage is 3.7V, and power bank needs to increase the voltage to 5V when charging the mobile phone, which making the power bank’s conversion efficiency only 3.75/5=74%, Also include generated heat when battery voltage boosting, and various of wire consumption, Electricity and self-consumption. these points add up to account for 30%-40% of the power of the mobile power source.So the 10,000mAh power bank can really be used by us only about 6200mAh.
Also, The conversion rate of the entire mobile power industry is basically in the range of 60%-70%. Please kindly noted.

The appearance of powerbank corresponds to the description. The declared capacity is 10000 mAh, the nominal same 6200 mah-for 600 rubles I would say that it is not bad. Executed qualitatively, charges and charges quickly. Brought by courier delivery service in 5 days, warning in advance that they will be by a certain time. Seller recommend

Well, it will. Delivered by the delivery service, which I did not ask and with very bad reviews online, in 2 weeks! When I opened it, I thought it was broken, so I heard the pieces of something flying in the box. The good broke only “substrate” plastic, so that the delivery of the claim is not particularly. The bank itself is intact and safe, almost fully charged. Looks cute, nice to hold in your hands. Functions of fast charging it does not have (!). For such money in principle is not bad. Comes with a short USB cord. There is a distrust to the bank, I think that it will not last long. But there are no assumptions for it, just a personal feeling. Buy you or not? I don’t know. As you want ….
