Powertraveller Powermonkey Explorer 2 packs a whopping 6000m Ah into its lithium ion rechargeable battery. This can re-juice you iPhone 5 or other smartphone about 3 times! It will also charge your Go Pro (4times!), GPS unit, iPad, Sat-Navs , rechargeable head torches & a plethora of other 5V devices. The incredibly robust, anodised casing is easy to grip & is that tough that it can support the weight of a Landrover Defender. (we dont recommend you actually trying it because lets be honest, that would be silly). The attached cables are IP65 rated to keep out splashes & dust. The unit seal itself has a rating of IP67 meaning it is waterproof for 30min at a depth of 1m using the supplied cabel. It has been tested to work within a temperature range of -30ºC to 50°C. This stupidly tough design can withstand heavy knocks & spills, it can perform in harshest of environments without compromising on charging capabilities; its pretty damn awesome. Looking into the future, the Powermonkey Explorer 2 will eventually have its own hand crank & wind turbine modules. The ability to add future power generation options makes this a world-class product, set at the forefront of portable charging technology. The powermonkey explorer 2 can also be charged via Powertravellers famous Solargorilla and the forthcoming Solarmonkey expedition solar panel.
