Portable foldable solar charging kit designed for reliable power on the move. conversion efficiency and a robust 50A charge controller deliver usable DC output and USB charging while protecting connected batteries and devices. Key benefits Maximize solar output: 23 to 24 percent conversion efficiency captures more energy from direct sunlight to reduce charging time. Versatile power outputs: Provides DC 18V and 9V outputs plus USB 5V for phones, tablets, cameras, and other 5V devices. Safe battery management: Advanced 50A charge controller with automatic 12V and 24V detection, dual USB 5V 2A ports, and builtin protections against overcharge, overdischarge, and short circuits. Durable for outdoor use: IP65rated monocrystalline cells and a coating resist rain, dust, and typical outdoor exposure for extended field use. Extremely portable: Weighs just 20.4 oz and folds to a compact 11.02 x 11.02 in for easy packing and carrying. How this product solves common problems Charge on demand: conversion efficiency and multiple outputs let you charge batteries and devices directly from the sun, reducing dependence on wall power in remote locations. Protects your battery: The integrated 50A controller automatically senses battery voltage and applies protections that extend battery life and prevent damage from improper charging. Built for travel: Lightweight and foldable design makes it practical to carry on hikes, camping trips, or in a vehicle without adding bulk. Function, compatibility, and performance highlights Conversion rate: 23 to 24 percent under direct sunlight for efficient energy capture. Outputs: DC 18V and 9V for compatible chargers and devices; USB 5V for standard USBpowered equipment. Charge controller: 50A capacity, automatic 12V/24V detection, dual USB 5V 2A ports, and builtin overcharge, overdischarge, and short circuit protections. Construction: IP65rated monocrystalline solar cells and a coating for weather resistance. Size and weight: Folded dimensions 11.02 x 11.02 in and weight 20.4 oz for compact portability. Compatibility: Works with 12V and 24V battery systems and most USB 5V devices. Practical use scenarios Day hike and backcountry charging: Attach the panel to a pack or set it up at camp to keep a GPS, phone, and camera charged during multiday outings. Car camping and RV use: Maintain a 12V or 24V battery bank while running LED lights, small appliances, or charging power banks and devices. Emergency and travel backup: Store the folded panel in a travel bag or vehicle for quick deployment during power interruptions or when on the road.
