ESPOW solar laptop charger has been making backpacks and laptop cases with built-in solar chargers since 2004. But so far most of the companys backpacks have only generated enough electricity to charge small items such as phones, cameras, or tablets.

Now Voltaic has introduced a new 10W backpack called the Array which can charge a laptop computer. If your Solar laptop charger attached to your current backpack, you can also pick up the slightly cheaper Fuse 10W Solar laptop charger, which is designed to be strapped onto an existing rugged backpack.
Both systems include three 3.4 Watt solar panels and a 16000mAh, 60 battery. This allows you to charge the battery whether your computer is plugged in or not. You can then use the battery as a backup battery for your computer. You can also charge the battery without the Solar laptop chargers by using an included AC Charger.
It takes 12 hours of direct sunlight to charge the battery, or half that much time if youre using the AC adapter. Voltaic says that youll generally get about 30 minutes of laptop run time for every hour in the sun.
The Solar laptop charger battery also has two outputs, so you can charge a laptop and phone, tablet, or other device at the same time.
Taking your laptop entirely off the grid doesnt come cheap. The Solar laptop charger Charging backup costs,while the Fuse charger is $339.
The backpack measures 18 x 14 x 8 and weighs 5.5 pounds including the battery and Solar laptop chargers. It can accommodate laptops with screen sizes up to 17 inches. Its made of waterproof fabric from recycled PET.
