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.

I'm so glad to hear that I am not the only one with problems. I used it in 2017 and it did charge the battery at least partially. But never again. I sent it to the Philips service department but, after 2 months or so, they said it worked. It doesn't. I argued and got a replacement panel. I backpacked with it for 10 days in 2018 and never got it to recharge. I was ticked for carrying the extra weight. Then I bought a new battery thinking that was the problem. Still no charge and it's not returnable. The light comes on the panel but not the battery. Now I have two batteries which, fully charged, should last for 4 maybe 5 nights, if I'm lucky. But they weight 2.2 lbs together plus the weight of the cpap! So much for ultra light hiking.

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.

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.
