Lightweight, Durable & Powerful: The Portable Solar Charger's military grade PowerFilm Solar modules begin charging the battery immediately when placed in the sun, even in low light conditions. In full sunlight a completely depleted P4 Overnight battery will charge in approximately 6-hours and a completely depleted P8 Multi-Night battery will charge in approximately 12-hours. If your battery is less depleted then charging time will be reduced.
Simple & Easy to Use, Perfect for Remote Locations: The Transcend Solar Charger is a 14W, foldable solar panel designed specifically for use with Transcend CPAP Batteries -- no extra cords or adapters are needs, just plug your Transcend P4 or P8 Battery into the Solar Charger and you're ready to go. When rolled up the Solar Charger is about the size of a small, folded newspaper and easily stows in a backpack or travel bag. In use it unfolds to dimensions of 54.5 x 12.5 inches for efficient and convenient charging.
