[Product Review] Resmed Converter with Jackery Explorer 160 Battery
#1
Resmed Converter with Jackery Explorer 160 Battery
I recently used a ResMed Air10 DC/DC Converter 90W (model 37003, product #37297) and a Jackery Explorer 160 portable power station to power a ResMed AirSense 10 Autoset during a short off-the-grid camping trip.  This setup worked perfectly, with one capacity caveat noted below.

Jackery's website states that the Explorer 160 should not be used to power CPAP machines, instead recommending a significantly larger and more expensive model.

I found the Explorer 160 had plenty of juice for 2 full nights (approx. 7 hrs per night), with 20% capacity remaining after the second night.  I was able to recharge the battery after the second night back to 45% capacity from a car's 12V cigarette lighter with the vehicle idling for an hour.  That gave me enough juice for 7-1/2 hrs the 3rd night, with 5% capacity remaining.

I used the Explorer 160's 12V DC output to power the ResMed converter, which in turn delivered 24V DC to the ResMed AirSense 10 Autoset's input.  To minimize power usage, I turned humidification and temperature off.  The Autoset operated in APAP mode, with pressure settings of 8.0 min to 16.0 max and EPR 2 full time.  Average pressure (IPAP) for the 3 nights was 11.02 (average EPAP = 9.02).  As far as I could tell, the therapy provided by this setup seemed identical to the therapy I receive using normal AC power.

I purchased the ResMed converter from Supplier #1 and the Explorer 160 through Mr. Bezos' company, fulfilled by Jackery itself.

RE: Resmed Converter with Jackery Explorer 160 Battery
Looks like a nice 4-pound solution for $149 on Amazon, but I might take the advise to opt for the larger Explorer 240 at $249 (6.6 lbs) for the additional capacity. The question is, how will long-term durability be if you continue to draw the battery to near-zero capacity. I would want to keep the charge state above 50% to avoid potential damage. In addition the 240 is supposed to provide a pure sine wave vs the square wave of the 160. This might be better for the CPAP. Good lead, thanks, and hope you will continue to update your experience here.

RE: Resmed Converter with Jackery Explorer 160 Battery
You're right Sleeprider, as usual!  The capacity of the Explorer 160 is sufficient for a couple of nights off the grid, but additional nights seem to require at least some recharging, and the lack of a true sine wave is also less than ideal.

I chose the Explorer 160 instead of the 240 for two reasons: (i) the 160 is $100 less expensive, and (ii) the 240 is too powerful to be carried on commercial flights or put in checked baggage in the U.S.  TSA regs prohibit transporting uninstalled lithium-ion batteries (including power stations/chargers) of any size in checked baggage, but allow lithium ion batteries up to 100 watt-hours to be carried on.  With the relevant airline's consent, a passenger may carry on up to 2 lithium ion batteries with capacities of 100-160 watt-hours.  Since I was flying to and from my camping destination (and not having a private jet at my disposal), I was limited in the capacity of the battery I could take with me.  Arguably I shouldn't even have taken the 160 on board my flights since it has a 167 watt-hour rating, but it cleared TSA's inspection both coming and going.

Here's the link to TSA's FAQ on batteries carried by airline passengers:

RE: Resmed Converter with Jackery Explorer 160 Battery
I have a Jackery Explorer 290 and a Dream Station2 CPAP.  I also have a power cord device that has a cigarette connector to attach to the Jackery and the plug that fits the Dream Station2 with an output of 19.5 volts.  Is that voltage too high?

RE: Resmed Converter with Jackery Explorer 160 Battery
The Resmed machines operate on 24 volts DC. When using a 12-14 volt source there are Resmed DC 12 to 24 Volt converters that will deliver the correct voltage to the CPAP. I'm not certain what happens when connected to a 19.5 VDC source.

Lakeranger: As far as I know, the DreamStation 2 operates on 12 volts; I would be very hesitant to connect 1 19 volt supply to it. Just because the plugs fit, it doesn't mean everything is compatible.
