Has your action camera run out of battery again in the back-country on ski tour? Your smart phone drains your rechargeable battery like a triathlete drains his hydration pack? Then the Explorer 24 solar panel by Brunton is just the right solution for any shortages, large or small, in your energy supply. The Sunpower Photovoltaic cells ensure 24 Watt total output and dont just fire up USB devices. Even 12, 15 and 18V are made possible via the variable output. An integrated IC Control Chip supplies the correct voltages and continually optimises the output level using the Auto-sync function - always adjusting to the suns current position. Theres no catch to this device. The Explorer 24 can be folded together very easily and so only takes up a quarter of the room. Just perfect for transportation, whether in your car or backpack. The device is also protected from external influences by a robust case.
