The extreme solar is a lightweight, clamshell solar panel, offering a 5 watt, 5V 1A (Max) output - perfect for charging smaller devices such as smartphones, GPS systems and handheld action cameras on the move. The panel opens to a 210 degree angle, making it easy to attach to back packs, tents or bike panniers whilst allowing optimum power from the sun. The extreme solar features useful 2-colour LED indicator; when the LED shows red, solar charging is at a minimum, when the LED shows green in colour, solar charging is at an optimum level. Housed in a rugged, water-resistant casing, the extreme solar includes MPPT technology which means the panel will still deliver power even in low light conditions - offering users reliable solar charging from a compact unit.
