21W Foldable Solar Panel Charger with USB A & C

Reliable solar power for phones, tablets and gear outdoors

This 21W foldable solar panel delivers stable 5V USB power for charging smartphones, tablets, cameras, GPS devices and power banks when you're away from mains electricity. High-efficiency photovoltaic cells are arranged in a flexible, fabric-mounted array that folds down for transport and unfolds to maximise sun exposure at camp, on the trail or on the road.

The panel integrates USB-A and USB-C outputs with PD (Power Delivery) and QC 3.0 fast-charging support, allowing compatible devices to charge faster than with standard USB. Additional regulated 9V and 12V outputs expand compatibility to a wider range of small electronics and portable batteries. The weather-resistant outer layer and reinforced stitching are designed for regular outdoor use, from day hikes to extended trips.

Lightweight and compact when folded, the panel features multiple attachment points so it can be secured to backpacks, tents or vehicles. Simply unfold, angle towards the sun and connect your device - no additional controller is required for USB charging. This makes it a practical solution for keeping essential devices powered during camping, hiking, travel and emergency backup situations.
