While charging, the device won't power on. It has to be disconnected form the charger, set on and then connected to the charger again in order to have it active, while charging.
VZ sold it for $50 and that's a great deal. The only recurring irritation (limitation) is the charging characteristics of the unit. When you plug in the 110v cord, the unit will not charge if you are still using it, even for a simple app like reading a book. The battery meter continues declining and when it hits zero, the tablet shuts down, even though the charger is plugged in. When I went back to VZ about it, they said the only fix is a high power battery for $130 to charge it while using it. What a drag to have to be so battery conscious all the time. Otherwise the unit is very good.
