CPAP freedom

At last i can enjoy thunderstorms without fear of having my sleep ruined by an electrical outage. A first class product, easy to use and incredibly reassuring for those of us who can’t sleep properly with a CPAP.


Followed the instructions to shut off the humidifier and put it in airplane mode. I got two nights on one charge.


Yes, we received the unit And got it up to full charge. To be honest with you. I have not used it with my CPAP machine yet because we got this for power outages back up. When I do use it though, I will let you know. Thank you.

EXP PRO batteries can be recharged 4 different ways:

-AC power (Standard wall outlet) - Included
-DC power (Car 12v socket, other batteries) - Included
-Solar panel (We recommend the EXP PRO 60 Watt Solar Panel
-Type-C port - Use PD charger for faster charging 

Connecting To Your CPAP

The EXP48PRO includes the DC power cord that connects the battery to your CPAP machine.  Please be sure to select the correct cord for your machine when ordering. 

Since any inverter, either built into the battery, or a stand-alone item consumes a fair amount of power we recommend using the DC power cord.

Have used this battery as well as its bigger brother. It is a powerful yet fairly light unit. It recharges in about 2.5 hrs after 1/2 depletion. I can get at least 2 nights (14 hrs) use with my Resmed 10 without the humidifier or heated hose activated. I got 5-6 nights with the larger battery without humidifier and heated hose. Overall, happy with this and would recommend.


I had purchased some batteries in the past and I wasn't too happy with them. I decided to give it one more shot and I bought this one. This battery is amazing! It lasts a while and doesn't take that long to fully charge. My machine works perfectly while it is plugged in and I can use it for about 2 nights before I need to charge it. I'm so happy I finally found a battery I like.

I live in Florida so I wanted to buy a battery to use in case of a hurricane. I looked around and finally decided on this one. I charged it once I received it and hooked it up to my machine to see how it would work. My machine worked the whole night without interruptions and I was even able to hook up my machine to it the next night as well. This battery is definitely worth the price!

Big capacity, but small size and weight when compared to sim I tested this and I was able to get 3.5...nights of 7-8 hours of sleep with the Z2 running at 13-14 hg pressure. Hopefully after a few uses the battery will get 4 complete nights, as batteries tend to not be full capacity until they get used a few times. Overall I'm satisfied and I'm thinking of getting a second one for an extended remote camping trip to power camera battery recharging equipment.
