Instant Off-Grid Charging (No Built-in Battery)
The V21W5V is a true USB solar charger that converts sunlight into usable power—no internal lithium battery to worry about. Just unfold the panel, face it toward direct sun, and start charging compatible devices. It’s a practical portable solar panel charger for outdoor trips where you need lightweight, simple power.
21W Output for Daily 5V Devices
With 21W (Wp) panel power and 5V output, this solar battery charger supports common 5V electronics such as phones, earbuds, small fans, GPS devices, and other USB-powered gear. Performance depends on sunlight intensity, angle, and shading—best results come from full sun and optimal tilt.

Built for portability, the V21W5V folds down small for backpacks and storage. Unfold it to capture more sunlight, then pack it away quickly when you’re on the move. This foldable solar panel charger is ideal for hiking, camping, road trips, and outdoor work setups.
Durable PET Mono Cells for Outdoor Use
The panel uses PET surface material and high-efficiency monocrystalline cells to help improve durability and everyday outdoor usability. Whether you’re in a campsite or on the road, the V21W5V is built to be a reliable solar panel charger you can carry and use repeatedly.
