Hi. I'm considering getting the Transcend 3 travel CPAP. However, I've read some bad reviews of the P8 two-night battery (only a 9 month warranty, dies within a year, etc.) Two questions: (1) What's your experience with this battery? (2) Are there other lightweight batteries that would work with the Transcend 3, or should I stick with the one that's made for it?
Thanks for any advice you might have!
