Dear Customer: As the Chinese New Year is approaching, the COVID-19 virus will be controlled at the same time. The customs port has entered a semi-closed state. The power bank logistics company notified the temporary suspension of logistics transportation channels. The restoration date needs to be February 28. Customers who need to buy power bank should try their best to buy from non-Chinese shipping locations. Orders from China's shipping location will extend the time. Sorry for the inconvenience caused to you. I hope that in 2021, we can move forward together.




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 6500mah/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 6500mAh.

Also, The conversion rate of the entire mobile power industry is basically in the range of 60%-70%. Please kindly noted.

Please search on Google if want to know the details
