Powermonkey-eXplorer

Unlike some of the more fragile solar chargers we've seen, the Powermonkey is built to withstand occasional rough handling - essential for a tool designed for use on the move. The soft rubber coating protects it from knocks and adds a certain amount of protection from moisture.

Its ruggedness isn't the only area in which it excels. While most chargers simply inform you when they're fully charged, the eXplorer has an indicator LED and an LCD showing the exact battery level. This makes it far easier to judge when certain devices can be charged. The detachable battery pack and solar panel also free you from carrying both when the battery is full and the panel isn't needed.

Our only real criticism is that it comes bundled up in a lot of packaging, including a disposable box and a reusable nylon carry case. With a product as rugged as this it seems unnecessary, and adds to the price and environmental footprint of what would otherwise be a very green product.
