Anker PowerCore 15600
Does your phone run out four, maybe five times a day? Unlikely, but the Anker PowerCore 15600 has you covered regardless. This power pack boasts a ridiculous 15,600mAh battery, enough to top up an iPhone 6 five times over, a Galaxy S6 four times, or an iPad Air 1.5 times. Charging is also ultrafast thanks to dual 2.4A USB outputs coupled to PowerIQ, which replicates the charging protocol of each plugged device’s original charger.
