The Easylonger cpap batteries are a much better bang for the buck. I got the 72000 mah with resmed connectors for $169. EASYLONGER ES720 CPAP Battery Backup, 266.4Wh Portable Power Supply for ResMed AirSense 10/11, AirCurve 10/11, AirMini, Philips DreamStation 1/2, Emergency CPAP Battery for Outdoor Camping https://a.co/d/038YOV8S For passthrough power when there might be an outage you need the resmed 12v car adapter. I get 2 nights with low humidity and low heat.
