The charger has USB sockets through which you can charge your devices such as a smartphone, tablet or portable battery. When you connect the solar charger to a portable battery, you can store the electricity there to charge your smartphone later, or you can use it as a stabilizing interface while charging (if your portable battery allows simultaneous charging and power supply). With the included clips, you can attach the solar charger to your backpack when you go on an adventure.\u003c\/p\u003e\n\u003cp\u003e \u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003cbr\u003e Model: 420-70\u003cbr\u003e Solar panel output power: 21 W \/ 7.6 V\u003cbr\u003e Solar cells: monocrystalline, with high conversion efficiency of 22%\u003cbr\u003e Connectors: 2 × USB-A (female) 5 V \/ 2 A\u003cbr\u003e USB output: 2 × 5 V \/ 2.1 A (total maximum 21 W)\u003cbr\u003e Dimensions (opened): 53.9 × 27.8 × 0.3 cm\u003cbr\u003e Dimensions (folded): 19.6 × 27.8 × 3.1 cm\u003cbr\u003e Weight: 0.68 kg\u003c\/p\u003e\n\u003cp\u003e \u003cstrong\u003ePackaging information:\u003c\/strong\u003e 1x Sandberg Solar Charger 21W 2xUSB, 4x carabiners, 1x user manual\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/div\u003e\u003c\/div\u003e Official manufacturer's website: https:\/\/sandberg.si\/sl\/product\/solar-charger-20w-2xusb\u003cbr\u003e\u003cbr\u003e\u003ch2\u003eSame summary\u003c\/h2\u003e\u003cp\u003e The Sandberg Solar Charger 21W 2xUSB solar panel charger is designed for users who travel frequently, spend time outdoors or need a reliable solution for charging mobile devices without access to a socket. Due to its portability and the possibility of using two USB outputs, it is a particularly useful choice for those who want to charge multiple devices at the same time, for example when traveling or camping. It is important to check the compatibility of cables and devices, especially if you have models with specific connectors, as the universality of connectors is not always perfect. The panel offers basic protection against overvoltage, but the charging speed may vary depending on weather conditions and sunlight.\u003c\/p\u003e\u003cp\u003e \u003cem\u003eRecommendation source: Enaa guides and team experiences.\u003c\/em\u003e\u003c\/p\u003e\u003ch2\u003e User view\u003c\/h2\u003e\u003cp\u003e Typical users of this solar panel are travelers, hikers, camping enthusiasts and anyone looking for independence from electrical sources in nature or on the go.
