    This charger when plugged into the ac power was fully charged out of the box in around 3.5 hours. Bought it for emergencies because of the storms and hurricanes we get around NC.

    I bought this to use while traveling. I need to be able to charge my 5th generation I-pad and my Android phone. It worked great on the phone but totally inadequate for the I-pad. The salesperson didn't know this. I returned it and bought a more recent model (Power core + II) on Amazon.

    This is my 2nd PowerCore. This one is even better with the 3.0 port. The power remaining indicator tells when to recharge. I take this hiking so mapping app on phone is always powered up.

    This is so handy and convenient in flight when you need to charge your phone and computer. It’s a little bulky but It is worth the extra weight for the quick charge and convenience.

    Used this charger on a two week trip to PR. It charged a Nintendo Switch twice and a iPhone at least three times before dying out. A must buy for anyone always on the move.
