After using the New Trent Enerpak USB chargeable 12000 mAh heavy duty charger, I wanted something for the shorter trips and to top off my devices.  I received the IMP52D iTorch.  At the time, my Ipad was at 70% and this wonderful little charger brought it to 100% in 1 hour and 38 minutes.  The charger showed 75% remaining.  I then charged my Iphone.  It took 1hour and 59 minutes, leaving 25% on the charger.  No complaints here.  I keep it charged at all times to top off my Ipad, Iphone and Kindle Fire.
