The Jumpr™ Portable Solar Power Banks can fit inside a variety of bags and can power smartphones, tablets, and MP3 players. I was impressed with how thin and sturdy they were. Positioned highest, on the rear pedestal sat the crown jewel of the Enerplex lineup, the GENERATR1200™. The representative explained to us that the GENERATR1200™ is a 1231 watt-hour lithium ion solar battery, capable of powering and charging large electronics from smartphones and tablets to refrigerators and televisions. What makes the GENERATOR1200™ superior to other batteries is the fact that it's 60% lighter.
