Bundle - CPAP Battery/Backup Power Supply and Car Charger - for Philips Dream Station, System One and other 12V Devices - the Smallest and Lightest Battery

I have used this battery with a Remstar Auto A-flex. It lasted me 2 nights of camping in low degree weather. Would recommend.

In mid-June 2022, my wife and I concluded a 73-day road trip in our Subaru Outback, which we had converted to a mini-RV for the occasion. The 15,818-mile trip extended from Mexico to Canada and in the U.S. from the Atlantic to the Pacific.We slept in in the Subie RV for a total of 34 nights--mostly in campgrounds, but sometimes in the driveways of friends and family--and on each of those nights, I powered my CPAP machine with the 12-volt Medistron battery.It worked GREAT!Specifics: Phillips Dreamstation Two CPAP machine, with humidifier off, non-heated tube, using the Fisher & Paykel Simplus nose mask (which I thought might use less energy than my F&P nose/mouth mask). Medistron battery was charged while driving, using the accessory car charger. Charge time about three hours--maybe less. One charge powered the CPAP for two solid 9-hour nights of operation. Simple to charge and use.I could have used the Dreamstation's power block and cable to charge the Medistron battery from standard electrical outlets, but never needed to do so. Often we called on the Medistron to power and charge an iPhone and two iPads when their batteries ran low.As I've only owned the Medistron for a few months, I can't speak to its longevity--but it appears to be a well-built, quality product. I plan to charge it up at least twice a year as directed, and hope it will last for a lot more cycles.This thing is pricey, but in my application it was absolutely priceless.

I have a Philip Respironics system one - REMstar auto 567. According to both the manual and the product description, this pilot 12 model is compatible with this device. However, it does not work. Every time you plug in, it battery gives out error message. I'm returning it.

Avoid this CPAP battery like the plague. In discussion with my Medical supply company, ResMed highly recommended this portable and rechargeable battery. In reality and for the price, it is a hugely underperforming battery. Even following the instructions for turning off my ResMed 10 features to maximize the charge length, this battery lasts maybe 5 hours. You will NOT get a full night of CPAP use with this battery. And, I have a friend who confirms this poor performance with this same exact product! Do NOT buy it!

CPAP back up battery/bundle. Purchased for a caravan holiday, however due to Covid, have been unable to use it as yet. The product is excellent and was the best price available. Also delivery was sooner than expected. Happy customer.
