FAQ
-
Q: Why doesn’t it show 35W when charging my phone?
A:The 35W rating refers to the maximum output when used as a wall charger. When charging an iPhone, the power bank provides up to 27W fast charging, which is the maximum supported by iPhones.
-
Q:Why does it take so long for the power bank to recharge when plugged into the wall?
A:When charging in AC mode, the power bank uses a 9V⎓3A input, which provides a stable and safe charging current to protect the battery cells and extend their lifespan. A full recharge takes about 2 hours and 38 minutes, which is normal for its 7000mAh capacity and fast-charging circuit design.
-
Q:Why does the power bank seem to drain so quickly while charging my phone?
A:The power bank supports fast charging, which means it delivers power at a higher wattage to charge your phone faster.
-
Q:Why doesn’t it show the full 7000mAh capacity?
A:The 7000mAh refers to the typical capacity of the built-in battery cells before power conversion.
Part of the energy is lost through voltage conversion, so the actual usable capacity is about 4000mAh, which is typical and normal for all power banks. -
Q:Why does it charge my laptop slower than expected?
A:Smaller power banks are mainly designed for phones, tablets, and other small devices. It only support charging MacBook laptops.
