POWEROAK CPAP Battery Power Supply External Battery Backup Power Bank for ResMed S9,Air-sense 10,Philips Respironics- Dream Station,Remstar System One 60 and 50,Transcend mini,HDM Z1. : desertcart.co.uk: Business, Industry & Science

Review: A real CPAP find...... - I needed a battery for my CPAP, mainly for any overnight/long haul flights, where there isn't an available power socket (NB: I have not checked with any airline that I can take this on-board as some airlines, such as Virgin, don;t even allow CPAP use without prior consent). The official ResMed battery in the UK is £480 inc VAT, which is a complete rip-off and exploitative, and gives you up to 2 nights back up. I found this product for £315 (saving of £165), and checked out the company web-site to make sure it's not some fly by night. It's a Norwegian company that seem to supply industrial power solutions. So I decided to buy one. It has a handle and is relatively easy to carry, but note it is quite heavy at 4lb for it's size. It also appeals as can be used to power laptops/phones and not just the CPAP. I use a Resmed Airsense 10. Once purchased, they contacted me prior to despatch to check it was compatible with my machine. It came well packaged and with a number of connections. You have to check you have connected to the right voltage. I charged for around 4 hours to get it to 100% on the display (it came part-charged) and used it last night. The down side was that when turning on and selecting voltage it does 'beep' which was annoying as my partner was asleep, so next time I will make sure it is connected before we retire. The upside was that it worked perfectly throughout the night and records 80% of power left this morning ( I hade around 8 hours sleep) so this machine will give up to 5 nights sleep, as opposed to ResMed's 2 nights for more money. So bottom line....can't fault it at the moment and very pleased with purchase. Will update here if anything negative comes out over the next few months but certainly pleased at moment.
Review: Excellent power backup for my ResMed S9 and AutoSense 10 - CPAP PowerOak review It took 5 hours to charge from 0% to 100%. 1st night: 8 hours use, dropped to 72% (WITHOUT humidifier) 2nd night: 7 hours use, dropped to 0% (WITH humidifier) If my math is right, I can use PowerOak for roughly 4 nights with 7 hours usage. With humidifier, was just a test, but it was good to see that I can get one night good sleep, but wouldn't start 2nd night, as I am terrified that I would be cut-off from power supply in the middle of the second night. COMPARISON BETWEEN MEDISTROM CO-PILOT 24 & POWEROAK As I own both, I can now compare the two. DESIGN Co-Pilot 24 has a sleek design and looks like majority of power banks, external hard drives and similar. PowerOak is much larger, and with a carry on handle, it is easier to carry around. (Co-Pilot: WON, PowerOak: 0) SIZE Co-Pilot 24 is smaller in design than PowerOak. Even with Co-Pilot 24 Plus, that doubles the power of Co-Pilot 24, is still smaller and thinner than PowerOak. (Co-Pilot: WON, PowerOak: 0) POWER Co-Pilot 24 gives me one and half night of power. With combination of Co-Pilot 24 Plus, I can get 3 nights of roughly 7 hours of usage. PowerOak gives me 4 nights of roughly 7 hours usage. (Co-Pilot: 0, PowerOak: WON) TRAVEL Co-Pilot 24 is allowed as carry-on into the airplane, PowerOak is not. (Co-Pilot: WON, PowerOak: 0) PRICE Co-Pilot 24 = £399 to £639 (plus £7.99 delivery) from desertcart Co-Pilot 24 = £365 (plus £7 delivery) from eBay Co-Pilot 24 Plus = £333 (plus £7 delivery) from eBay PowerOak = £259.99 (£234.99 with £25 voucher) (Co-Pilot: 0, PowerOak: WON) SUMMARY Despite Co-Pilot 24 won in my little test, it is really down to what YOU prefer :-) ... I like to have a choice and freedom, so have bought both of them. Will use my Co-Pilot 24 for my frequent flights, but PowerOak, when I go camping or similar, where I will spend a weekend or a few nights in a middle of nowhere.

## Questions & Answers

**Q: where can I buy a replacement power cable to connect it to my cpap resmed airsense 10?**
A: Well I'd contact poweroak first or try eBay. Failing that a computer shop usually has a wide selection of cables and connectors, or try an electrical or hardware shop.

**Q: I have a dreamstar evole would it be compatible with this?**
A: No idea, but
Comes with lots of adapters and works fine with my Philips system one

**Q: Can this be left on charge for several days or does it have to be unplugged from mains once fully charged?**
A: The operating instructions do not mention this situation. The Poweroak comes with a separate transformer, a lead from one end plugs into the mains power socket and the other lead runs from the transformer into the Poweroak unit itself. Recharging is quite quick. About 6.5hours from empty to full. It will recharge to about 98% in about 4 hours but like most batteries takes a while to cram in the last 2% or so! 
Once charged the battery seems to hold a full charge for several weeks. Possibly longer. The instructions say to ensure the battery is charged to at least 60% if it is in storage and to check it every 6 months to ensure it is at 60% (or above if you left it fully charged).
I suppose you could leave it on charge for several days if you had to. It appears to have its own management system so knows to stop charging. However as with all electrical items it is not good to leave things plugged in unnecessarily as even when not charging the transformer will be drawing power. So I cannot give you a definitive answer.
i have not yet posted a review of this product as I have been evaluating it. However I am impressed with its performance. It has run a cpap machine for 5 full nights in a row before needing recharging. Slightly longer if you ensure all non essential cpap functions are turned off. (ie put the device into aircraft mode if it supports this function and turn off any humidifier or heater function.) 
This has made camping and trips away much easier. The item is expensive but has now been used for a total of 40+ nights in the last 6 months with no apparent loss of efficiency (yet!). Just remember there is a separate transformer and wires to consider when packing it. If you are away for just a couple of nights you can recharge it when you get home and save carting the extra bits around. 
While this does not completely answer your question I hope it helps.

**Q: Is there a way to charge this powerbank in the car? with a dc adapter or a usb cable? thank you**
A: There is a USB port on the 'in put' side, but I have never tried this. 
The battery is fantastic. It lasts be 4-5 nights without the humidifier and 2-4 days with the humidifier. 
I would strongly recommend this product.

### ⭐⭐⭐⭐ It works.
*by A***O on 3 September 2021*

It works as expected. Used it for CPAP 5 nights in a row and battery life from 99% dropped to 36%. Very easy to use. Size is small and portable. Only drawback is that I didn't realise that it does not have UK 3 pin plug socket so that limits the appliances I can connect to it. Good for CPAP power back up and frees me from looking for wall socket when I travel.
