On some usb mobile charger and once it's full the only indicator that's on is the one led on the charger. The phone shows no other signs it's full unless I turn it on.
Hope this helps,
I have the tracfone LG 840g and bought the Motorola Vehicle Power Adapter micro USB rapid rate charger.
Should these chargers always show that they are charging the cell phone when connected? I notice nothing looks like it is charging up my phone. When I charge this phone with my regular wall plug in it shows the battery bars flashing and charging.
Do I have a defective charger or one that might be incompatible with my tracfone? Or could it be charging without any visible signs?
