Battery features updated Always On technology on the 2X USB-A ports. The output will not shut off even if your device is drawing low or no power. There is no low current cutoff.
To stop charging your device, double tap the Power Level Button or disconnect from the battery. To resume charging, tap the Power Level Button once.
Battery recovers into Always On mode after discharge, over-temperature and under-temperature events. Power consumption in Always On mode is approximately 7mA (26mW).
Always On is not active when charging from the USBC-PD input port on the top of the battery. Always On output is active when there is no input or when charging from the input port on the side of the battery.
