The RYOBI 21 Watt Foldable Solar Panel powers any small electronic device with a USB-A or USB-C port directly from the sun. It is ideal for powering your phones, tablets, power banks, speakers, and even your RYOBI 18V ONE+ batteries when combined with a compatible RYOBI power source. It can charge a RYOBI 18V ONE+ 2Ah battery in 3 hours and your phone in as little as 1 hour and 50 minutes. The 21 Watt solar panel is an ideal portable power solution, weighing in at only 1.5 pounds and measuring 12.25”x 6.5” when folded. The compact, lightweight, foldable design makes storing and transporting easy, so you can take it with you to charge devices when hiking, camping, at the beach, and anywhere under the sun where you’d need portable power. It can be opened up flat on the ground to capture light during peak sunlight hours, or can be strung up at a variety of angles using the (7) integrated hanging loops to maximize the amount of light it captures. The RYOBI 21 Watt Solar Panel is backed by the RYOBI 3-Year Manufacturer’s Warranty and includes the RYi20SP 21 Watt Foldable Solar Panel and an Operator’s Manual.
