Our mobile devices have precise battery meters, but the portable chargers for them may have at best a couple of LEDs. The Fig Battery Back takes the guessing game out of determining if your charger has enough power to restore you to Candy Crush saga heaven (or maybe hell). The Fig has two USB ports, making it able to charge both smartphones and tablets . The Fig also has the capability to recharge via solar power. Units are available in 6000 mAh and 10,400 mAh. For $59, a backer gets one 6000 mAh Fig unit with an expected delivery date of April 2014.
