I attempted to use the unit with a usb wall plug and initially thought the charger was defective because the display flickered or dont display anything when attempting to charging two batteries charging a single battery worked fine

That was the case regardless of the battery manufacturer

Save much time cause able to charge two batteries simultaneously and charging status visible via the blue led screen

Works well i gave it 4 stars for being very light and not solid

I dont recommend plugging this into a computer it may not provide enough power to the charger to charge the batteries adequately

The cable provided with the charger does work fine however it would be nice if it was compatible with all cables

The battery life read out on my camera seemed to be better than normal then one afternoon it said 34 charge and the next morning it said totally dead

Im not sure if that is the charger the batteries or related to having gps on for 4 days and the last day perhaps not having a gps lock all night
