Rarely review, but this merits attention. Used Resmed Airsense 10 for apnea. As a fly fisher, I've sought off-grid solutions, but car batteries & converters were a pain. This month, a helicopter trip made it worse. Bought this battery months ago, tested at home, got 32+ hrs. It charged fast, powered CPAP 35+ hrs, charged gadgets, and still had 25% left. Bad reviews on duration likely used power-hungry add-ons.

Durable. Bigger than expected but good. Ran Air mini all night, battery at 100% am, charged 2 phones. Tried Resmed pilot battery first, only lasted one use. This one has 2 USB, 2 12V ports, and a DC output. Cable for Air mini worked well. Comes with other good cables. Recommend for camping or power outages.
Name: Steve in Florida

During the hurricane, this battery was a lifesaver for my CPAP. I'd bought and tested it before. It powered the CPAP over 30 hrs and charged my phone. It's compact and easy to use. Ignore complaints about charging time; it's reliable. Highly recommend for backup power, especially for medical devices.
