* High Efficiency: The solar cell+ ETFE film coating is up to 21% efficiency, while most panels in the the market is 15% or even lower, providing enough power to charge devices.
* The charging temperature is -20℃~80℃, no worries about charging under low temperature any more.
* Bendable Panel: the panel can be gently flexed to follow a smooth curve of 30 degrees max. Industrial-strength ETFE polymer solar panels sewn into a rugged polyester canvas, providing weather-resistant outdoor durability.
* Widely Use: Compact size and stainless-steel eyeholes enable easy attachment to backpacks, trees, or tents, ideal for long treks. Charge your electronic devices with built in battery or solar panel anywhere and anytime
