Every one of our solar chargers and batteries will charge a tablet, but we recommend you use a larger solar panel (measured in Watts) and battery (in mAh or Watt hours) than if you are simply charging a smartphone.
Our most popular chargers for tablets are:
Arc 10W Kit with V44 Upgrade (10 Watts, 12,000 mAh)
While all of our batteries will recharge a tablet, only our V44 USB Battery and V88 Laptop Battery will reliably fill a laptop from 0-100%, since some tablet batteries are too large for the V15 to provide a full recharge.
To charge your tablet, simply connect the USB cable that you use to charge from the wall into the battery included with the Voltaic charger. The Voltaic battery can be recharged from the sun or any USB wall or car charger.
