At 1.6lbs (0.73kg), the HyperJuice 2 is the heaviest external battery featured here, but its large 27,000mAh battery will recharge your iPad, iPhone and other smartphone or tablet several times on a single charge. In fact, the HyperJuice 2 can even power a MacBook–with an Apple MagSafe Airline Adapter–for up to 18 hours of power. An OLED screen shows detailed battery information, including the percentage of power remaining, battery temperature and the estimated time to fully charge (or discharge). Finally, a modular design allows battery cells to be upgraded individually.
