“This portable charger saved me during fieldwork in remote parts of Africa. It can charge off of many different kinds of solar setups and a car battery inverter. It does not charge quickly, but the amount of charge it holds is well worth the long charging time. I used it to recharge two different kinds of tablets – an old ASUS that is probably not even being sold any more, and a Surface 3. In both cases the charger was able to charge the tablet at the same time the tablet was running,” said reviewer Cello on Amazon. More information.
