Those of you who have been following this blog for a long time know that we are a big fan of solar chargers. Not all e-readers can go for weeks on a full battery charge. The Solartab happens to be a solar panel with a built-in cover to ensure maximum sun exposure. The cover serves as a stand, so you can angle your solar charger towards the sun for maximum exposure to sunlight.
The device does have an internal battery, so you can use it even at night. The Solartab has 2 USB ports and a mini USB port. Since it has a portable design, you can use it anywhere. This exciting product will be Kickstarter soon.[Source]
