Resolution / Answer

The Power Pack provides additional power to charge the main battery. The longer the device battery is left without charging, the battery power will continue to drop. The Power Pack will deliver power to allow the device battery to come back up to a usable state.


After connecting Power Pack to terminal and followed by Power Pack button pressed, it takes around 5 minutes to boot up on ET55 terminal.
