Dual USB Solar Charger

Fast Charging Technology: PowerIQ delivers the fastest possible charging speed up to 2.4 amps per port or 3 amps overall under direct sunlight. 21 watt SunPower solar array is 21.5-23.5% efficient, providing enough power to charge two devices simultaneously. Incredibly Durable: Industrial-strength PET polymer faced solar panels sewn into a rugged polyester canvas offer weather-resistant outdoor durability. Highly Portable: Compact size (11.1 × 6.3in folded or 26.4 × 11.1in opened) and stainless-steel eye-holes on each corner allow easy attachment to backpacks, trees, or tents. Lightweight (14.7 oz) and ultra-thin design (1.1in folded or 0.2in opened) make it ideal for long treks.
