FAQ
Q: Power bank has two regular standard of capacity , one is the battery capacity, one is the rated capacity. The 20000mah power bank, being labeled 20000mah/3.7v core capacity be converted to rated capacity 13000mah/5v.
Why exist this happening?
A: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 20,000mAh power bank can really be used by us only about 13000mAh.

The product corresponds to the declared characteristics! Delivery took 31 days, most likely because of the coronavirus. Already 4 times I charge my phone to 100% and the indicator only for one division left!!! Thats cool! On nature you can take and not worry that the phones will sit down! In general, the thing of its money is worth, especially took on the shares for 950 rubles!!!

Características do produto corresponde ao declarado! 31 entrega demorou dias, provavelmente por causa de o coronavírus. Já 4 vezes carregar o meu telemóvel a 100% e o indicador apenas para uma divisão à esquerda!!! Isso é legal! Na natureza que você pode tomar e não se preocupe que os telefones vão sentar! Em geral, a coisa de seu dinheiro vale a pena, especialmente assumiu as ações para 950 rublos!!!
