OXSUN Folding USB Solar Panel
Unfold at your next stop. Original 21W with a pocket option.
Solar charging between the miles
A folding OXSUN panel for compatible low-power USB devices during cycle touring, camping and other outdoor trips. The fold-out design has hanging eyelets and a pocket for a phone or cable.
Panel rating and charging ports
The supplier rates the panel at 21W, with a panel working voltage (Vmp) of 9V. The separately specified charging outputs are USB-A 5V/2A and USB-C 5V/3A, 9V/2A or 12V/1.5A. These are supplier specifications, not guaranteed output; check your device and cable requirements against the supplied instructions.
Let the conditions set the pace
Solar output depends on sunlight, panel angle and conditions. The 21W rating is not a promise of continuous output or a particular charging time. This listing does not establish compatibility with electric-bike or scooter traction batteries.
What comes with this option
The exact selected listing specifies one solar panel charger, one cable and two carabiners. The supplied cable’s connector ends are not specified; check its suitability for your device before use.
Set up while stopped
Unfold and position the panel securely while stopped, keeping it clear of moving bicycle parts. Keep connected devices and the junction box dry, and do not immerse the panel charger. Follow the supplied use and care instructions.
