Rockpals DC Converter Compatible with S10 CPAP Series and Rockpals 300W/500W Portable Power Station

Good CPAP battery. Have had the battery since last October and it has worked perfectly each time I've used it. Can be recharged either with 110 outlet or 12 V. Also with solar panel according to instructions but I haven't tried that charging method.I had some questions about how it would work with my CPAP and Rockpals customer was excellent. Got right thru to a knowledgeable human without any phone robot machine. They were patient with my questions and answered them all.After a few months I managed to store the charging cord in a super secure location that even I couldn't remember. So I called customer support and again super service with no hassle and a new cord is on the way. Highly recommended.

good converter, compact, can use with a variety of battery packs or car cigarette lighter. Seems to work just as good as official Resmed converter if not better, and is cheaper and seems more durable. I use the version that fits the Resmed Airsense 10 CPAP instrument.

looks like a well built unit. do not have a use for it came with my product.

Read the product description and title carefully. Rockpals will not provide support or back their warranty if you use the converter with anything but their power stations. I used the product in an RV with a DC socket and it worked 1st trip out for a few nights. On my second trip, the converter stopped working because of an apparent short. I contacted support and was told because it was used outside of their power station they would not honor the warranty. I guess it's my own fault for not looking closer at the info provided, but maybe the next person who is in a hurry might benefit from my warning.

Tried it out and it works perfectly when used in the car. We had a battery pack but without this converter it would only run my machine for maybe few hours. With this it runs on dc converter for the whole night. Need to try few times and once located it works great than before.

I was pleasantly surprised at how many nights I got out of a single charge for my cpap. I couldn't take it on a plane and went to order another one and have it delivered to where I would start a road trip from. Great portable charge box and I will likely order another one.

After purchase it was used for 4 days in a camper without hook-ups. Did not run the battery down overnight like I was expecting. Uses less 12 volt dc power than a led light. Very pleased with this product. When ordered it was received the next day. Excellent service.

I did not get the charge cords pictured, so thought this photo was misleading. It can’t be taken on an airplane, but it’s for my RV and that doesn’t fly!

Rubbish. Stopped working almost immediately. Investigated the circuit board. Seems to be an unstable circuit - crap design.Replaced the FET with a compatible replacement.. circuit still failed.Do not purchase!!!!
