In its travels, portable power system manufacturer Powertraveller says that it's come across the question many times: "Can you make a battery with enough charge to run a laptop all day?" It now has an answer. The silverback-gorilla is its beefiest portable power pack yet.
The Solarmonkey Adventurer is the latest in Powertraveller's line of portable solar chargers. It's the company's first to offer an internal storage battery, providing a little more flexibility. As its name implies, the device was built to hold up to the rigors and abuses of field use thanks to the device's two solar panels being contained in an insulated clam shell case.
