Yes, you can use a mobile power bank when your device has more than 10% battery remaining.
However, if the battery level drops below 10%, Curtain and Curtain 3 will switch to trickle charging mode to protect the built-in lithium battery. In this mode, only a very small current is used for charging.
Most commercial power banks automatically shut off and enter sleep mode when they detect such a low output current, assuming the device isn't charging. If this happens, your Curtain/Curtain 3 may stop charging. In this case, please use a 5V1A charger or our solar panel instead.
