SunJack 40 Watt ETFE Foldable Portable Solar Panel Charger with Kickstands

The world's most versatile and powerful 40 watt folding solar panel charger. Compact, weatherproof and multi-use, these 40 watt solar panels fold together into an all-around charger perfect for camping, long trips, power outages, disaster prep and more!

Designed in the USA. Backed by a local American company.

RUGGED, DURABLE & WEATHERPROOF: Designed for all weather conditions and environments. Each of the four connected solar panels are sealed with a waterproof ETFE exterior layer that improves performance and durability, extends the panel’s lifespan and requires far less maintenance when compared to the exterior construction used by most portable solar chargers. The USB ports are waterproof rated IP67, the junction box’s PCB is coated with a waterproof seal and silicone bonded to the panel.

COMPACT & PORTABLE: The 4 panel system folds down to the size of a tablet and easily fits into most backpacks. The pocket provides storage space for electronics and accessories and the mesh design intuitively allows airflow to prevent devices from overheating. The elastic straps secure phones, power banks and more during storage, travel and transportation.

POWERFUL & FAST CHARGING SPEEDS: With up to 40 watts of power, the monocrystalline panels sealed with ETFE provide maximum efficiency and UV-ray permeability. The 21V DC5521 port (25.1V open circuit voltage) provides enough charging power for most power stations while the dual USB ports can charge most USB-C (PD30W) and USB-A (18W max) devices. The ETFE construction is highly efficient, with a UV permeability of 95% compared to 80% from standard PET construction.
