Great device runs my resmed 10 (no WiFi version) 4 hours with every feature on included humidity,heated tube. So with those off you’ll hit 1-2 nights at off temp and humidity. Great device works perfect just be aware recharging is slow

Very pleased. It powered my Resmed Airsense 11 for 5 nights (no heat) and recharged my iPad with 3% power remaining. It outperforms my two Medistrom CPAP batteries at a fifth of the price. This is an awesome battery. Downside: it takes a long time to recharge to full capacity. But it is a high capacity battery.

So far I would give it 10 stars. But to be fair I have only had it few days. I would like to have the opportunity to review again in 30-60 days, please give me that opportunity to do so. Please communicate that back to me.

Horrible. I’ve bought many products from you and the last doesn’t work and nobody will get back to me about how to repair or return it

I tested it at home overnight and used 70% of the battery for 8 hr powering a ResMed AirSense 11 with the tube at 82F and humidity set to 4 (ambient humidity was 30% RH). I still need to do a trial run without the humidifier and heated tube, but I expect a significant improvement.
