Can the battery charge from an USB port?
The iCarrier can only charge from the supplied AC wall charger. It will NOT charge from an USB port NOR can it be used in conjunction with the IMP03B (USB cable for New Trent power bank) to charge.
I pressed the power button and nothing happen, device does not charge!
The iCarrier : IMP120D has a delay on of 2 seconds, a simple press of the button will not turn battery ON. To properly turn ON and OFF battery press and hold power button for 2 sec and the light will turn On confirming proper initiation of battery, if device is connected (not silent) it will beep and the charge screen or icon will appear.
