Why is my power bank providing fewer charges than expected?

A power bank loses 30%-45% energy as heat during charging due to cable resistance and internal circuitry. A full charged 20000mAh bank provides about 11000mAh-14000mAh to devices.

How to activate the low current mode?

Double-click the power button to enter low-current mode.

How to keep the screen to always on?

Just press the button to access the "KEEP SCREEN ON" setting, then press and hold the button for 2S to select whether to keep the screen always on. Set it to "yes" and the screen will always on.

Why does the power bank stay at a certain battery level for a long time when charging? Is this phenomenon normal?

This is due to the power bank's heat protection, which lowers charging power when overheating. Charging returns to normal after cooling. This often happens after the battery depletes or charges at high power. It's a normal occurrence.

Why does the battery drain so quickly?

When the settings selection screen is always on,both the screen and MCU are working, so it is normal that the battery drains quickly.it uses about 18% of the battery in 24 hours. We recommend to turning off the display screen during use.
