3.5W/5V USB-C Solar Panel Charger with 3m Cable - Portable Outdoor Power Supply for 3V-5V Devices Lights, Cameras, Fans
Power small electronics sustainably with this compact 3.5W solar panel charger. Designed for low-power outdoor and emergency use, it delivers a stable 5V output via USB-C (Type-C) so you can run or top up compatible 3V-5V devices such as small fans, LED lights, monitoring equipment, and other USB-powered gadgets. With a high conversion rate of up to 22%, it's built to capture sunlight efficiently in good conditions - ideal for camps, cabins, sheds, and off-grid setups where mains power is not convenient.
A long 3m cable gives you flexible placement: mount the panel where it gets the most direct sun while keeping your device in the best position. The single-crystal silicon cell construction with PET lamination adds durability and helps the panel handle regular outdoor use.

Interesting facts about small USB solar panels
- Solar panels rarely produce their maximum rated power unless they re in strong direct sun and angled correctly - even partial shade can reduce output significantly.
- Longer cables can be helpful because the best sun spot is often different from where you want your device placed.
- Charging a power bank first can give steadier results than charging a phone directly, since sunlight can fluctuate with clouds.
Good to know
This panel is best for low-power devices. For stable charging of sensitive electronics, consider using a power bank or a suitable charging controller between the panel and the device.
