Monocrystalline cells with ETFE lamination convert sunlight directly into power. IP67 rating and foldable form make it practical for outdoor use.
Rapid daytime charging, thanks to 20W dual USB outputs
Monocrystalline solar cells convert sunlight into electricity, routed to two output ports, USB-A and USB-C, each rated at 5V/3A max. An intelligent charging chip negotiates current with connected devices for stable delivery.
Phones, USB fans and small power banks gain useful charge quickly in strong sunlight, as user feedback confirms strong performance in full sun.
Durable weather resistance, with ETFE lamination and IP67 rating
ETFE film combined with monocrystalline cells increases light transmittance to about 95% and supports a quoted 24% conversion efficiency, while the IP67 rating protects against dust and splashes.
The rugged construction stands up to drizzle and dusty trails, so the panel can be used confidently during multi-day trips and unpredictable weather.
Compact portability, with foldable form and carabiner mounts
Folds down to roughly 8.7 × 8.5 × 1.2 inches and weighs about 0.86 lbs, including two carabiners for hanging on a rucksack or tent. No internal battery is included, so devices must be connected to receive power directly from sunlight.
The panel stows easily in a daypack and clips to a backpack for charging on the move, making it a practical companion for lightweight trips and emergency kits.
