The Xtorm SolarBooster 21 Watt Panel AP275U is a compact, 21 watt foldable solar panel suitable for e.g. smartphones, action cameras, USB powerbanks and other USB and USB-C devices.
The 21 Watt solar panel is made of high-efficiency SunPower¨ solar cells, generating 25-35% more energy compared to other commonly used solar cells. The SolarBooster 21 Watt can generate approx. 60 - 70 Wh per day, depending on the weather conditions. The Solar Booster AP275U has two outputs. One USB-A and one USB-C. Under optimal weather conditions, a charging current up to 3000 mA can be generated.
For optimal use, combine the SolarBooster AP275U with a USB-(C) powerbank. The generated energy is stored in this powerbank and can be used for charging your USB-(C) devices at any time. With the handy LCD indicator, it is easy to see how much Ampere the SolarBooster is supplying at that moment. Tip: The yield in Watt is calculated by the Amperage x 5V = amount of Watt per hour. Example (1.4 A x 5V = 7 Watt). The SolarBooster 21 is made of a durable fabric, weighs only 425 grams and is the perfect addition for your outdoor gear.
Due to the handy design and the included carabiner, the SolarBooster 21 Watt panel is very easy to attach to a backpack, tent or bicycle. When the solar panel is not in use, it can easily be folded. The material used is waterproof, strong and flexible.
