Product description
Why isn’t the rated capacity 20,000 mAh?
Due to a 35% energy loss from the battery cells and conversion circuitry, a fully charged JUOVI 65W 20000mAh power bank (two 10000mAh cells) delivers an estimated 13000mAh to devices. Rated capacity: 13000mAh (5V/3A).
What is the power output when using multiple ports?
The power bank has a single circuit with a fixed power cap. One port gets the full 65W. Using multiple ports causes overload and severe heat, so the system automatically lowers the total power to a safe 20W and shares it among devices.
How to turn on the low-current mode?
Double-click the button to enter or exit low-current mode. In this mode, the device stays on for two hours and fast charging is supported.
Why does the output sometimes fail to reach 65W?
Because the product’s temperature rises quickly during high-power output. For safety reasons, the high power output is not stable; it will decrease as the temperature increases.
Why doesn’t the recharge speed match the description?
The recharge speed of a power bank mainly depends on the charger and the cable. If the input can reach 45W, the power bank can be fully recharged within 2 hours.
