Charges in One Day

Placed in direct sunlight, the Transcend Solar Charger takes approximately six hours to charge fully (for the overnight battery).

Military Tested Strength

Constructed from Power Film, the super thin charger is durable and comes ready to use. Simply unfold the device, lay it flat, and connect your battery to the charger.

Transcend Solar Charger Hiking Guide


Can I roll up the charger?

The Transcend Solar Charger folds more than it rolls. The solar panels fold on top of each other, and the device is approximately 10.5" x 3.5" x 2" folded up.

Does the charger come with, or come attached to my device's battery?

No, the charger is an external device that attaches to the battery. It does not come on any battery or CPAP machine.

Do I need to worry about keeping my charger clean?

Transcend designed its Solar Charger with outdoor use in mind. The charger can withstand some dirt and wear and tear. Clean any accumulated debris with a damp cloth.

This is totally worthless. Would barely add any charge despite a full 12 hours in the sun. Sent it back because I thought it was defective. Second charger was also worthless and would not charge a p8 battery. I'm looking for another option. The challenge is the proprietary plug on the P8.

Tried to use. Would not charge Transcend battery even after three days of full sun. Do not buy!

Bought this a number of years ago. Used it the first time then, although slow, seemed to work. I was excited. Then went to Iceland this year 2018, even with extended sunny days , nothing. Lit up but wouldn’t charge. Tried it again at home this fall in bright light outside, again got red light but no light when battery plugged in. Called manufacturer, they said past warranty. Expensive for one use!!! Don’t waste your money.
