PRODUCT DETAILS AND DESCRIPTION

Powerful, compact, weatherproof and multi-use – the SunJack 40W folding solar charger is an all around solar panel that does it all and is perfect for outdoor adventures, camping, power outages, emergencies and more!

RUGGED & DURABLE: Designed for all weather conditions and environments. The waterproof ETFE exterior layer improves performance and durability, extends the panel’s lifespan and requires far less maintenance when compared to a PET exterior layer that is used by most portable solar chargers. The USB ports are waterproof rated IP67 – the PCB is coated with a waterproof seal and the junction box is silicone bonded to the panel. Waterproof, shock-proof, dust-proof and drop-proof. Designed for all weather conditions and environments.FOLDABLE, COMPACT & PORTABLE: Comprised from 4 connected solar panels, the panels fold down to the size of a laptop and easily fits into most backpacks. The integrated pocket provides storage space for electronics and accessories, and its mesh design intuitively allows proper airflow to prevent devices from overheating.

The ETFE construction provides a UV permeability of 95% compared to 80% from PET – makes the panels more efficient than other solar chargers.SMART TECHNOLOGY: The panel includes multiple smart IC chips allowing the USB ports charge simultaneously with the DC port, at the most efficient voltage, and provide the quickest, yet safest, charging speed. Short circuit, over-load, over-heat, over-charge, over-voltage, and current limiting protection. Automatic restore if shade occurs.PREMIUM FEATURES & DESIGN: Includes everything you need for seamless charging on the go.
