The Xtorm Solar Charger 10000 is a robust, durable solar charger designed for outdoor use. It offers you freedom and energy to go wherever you want, making it perfect for all your adventures. The solar charger can be charged in two ways: either via USB-C or simply by taking it outside and letting the built-in solar panel do its job. The efficient SunPower cells work even on a cloudy day. If you leave the solar charger in the sun during the day, you'll have more than enough energy to recharge your smartphone at night.
