Our review
The Medistrom Pilot-24 Lite is a 95 Wh lithium-ion backup battery for 24-volt CPAP machines, sold with cables for the ResMed AirSense 10 and AirMini, that Medistrom says gives 1 to 2 nights of therapy with the humidifier and heated tubing off. This researched review reads Medistrom's product page, explains how the backup mode works, and says which machines need an extra cable.
What Medistrom lists
Medistrom's page gives a 95 Wh capacity from industrial-grade LG lithium-ion cells, a size of 6.7 by 3.5 by 0.8 inches and a weight of 1.3 lb, FAA compliance for air travel, and a recharge time of 2 to 3 hours (7 to 9 hours through the ResMed AirMini adapter). The box includes output cables for the ResMed AirSense 10 and AirMini and a short charging adapter for the AirMini.
Medistrom lists it as compatible with the ResMed AirSense 11, AirSense 10, AirMini and S9 and the Philips Respironics DreamStation Go, and says the AirSense 11, S9 and DreamStation Go need cable kits sold separately. The compatibility line also names 3B Medical Luna and Apex iCH among the 24-volt platforms it serves, and notes the DreamStation Go works with the Pilot-24 series only.
How backup mode works
The Pilot sits between the wall adapter and the machine. Medistrom says that while it is used as a permanent power backup, you can rest assured you will not be woken in the middle of the night to find your machine is not running: if the power is interrupted, the machine draws from the battery. That is the whole appeal for an outage: no alarm, no getting up to swap cables, and the battery is always full because it charges whenever the grid is on.
For the AirMini in backup configuration, Medistrom says to use its own AC adapter or ResMed's AirSense 10 adapter rather than the AirMini's. Our guide to CPAP in a power outage explains the trade-offs between a dedicated CPAP battery and a bigger power station.
Run time, and the humidifier rule
Medistrom's figure is 1 to 2 nights of continuous run time on an average pressure setting with the humidifier and heated tubing disabled. That last clause is the one to remember: a heated humidifier can multiply a CPAP's draw several times over, and 95 Wh will not carry it through a night. Turn the humidifier off, or set it to passover, as soon as the power drops.
High pressures, a full-face mask with leaks and a cold room all shorten the run time; expect one night with margin, not two. Medistrom does not give a watt figure for the output on the page.
Travel and limits
At 95 Wh the Pilot sits under the 100 Wh line that airlines allow in carry-on without approval, which is what Medistrom's FAA compliant note refers to; the battery still must travel in the cabin, not checked baggage. The page gives no warranty term in text, only a link to a warranty page, so ask the retailer.
It is a 24-volt unit, so it does not fit 12-volt machines such as the DreamStation 1 and 2 or the System One; Medistrom makes the Pilot-12 Lite for those. It also does not power ventilators.
How it compares, and who should skip it
Among the CPAP battery backups we list, the Pilot-24 Lite is the compact, always-charged option for ResMed users; a larger power station with a DC cable gives several nights with the humidifier on but costs more and has to be set up when the power fails. Our medical devices in a power outage guide covers registering with your utility and keeping a written plan.
Skip it if your machine is 12 volts, if you will not run without the humidifier, or if your outages tend to run for days: one 95 Wh battery buys you one night, and a second battery or a power station buys the rest.

How many nights will the Pilot-24 Lite run a CPAP?
Medistrom says 1 to 2 nights at an average pressure with the humidifier and heated tubing turned off. Plan for one night with a margin, and switch the humidifier off when the power fails.
Which cables come in the box?
Output cables for the ResMed AirSense 10 and AirMini and a short charging adapter for the AirMini. The AirSense 11, S9 and DreamStation Go need cable kits sold separately.
Does it switch over automatically?
Yes. Used as a permanent backup between the wall adapter and the machine, Medistrom says the machine draws from the battery if the power is interrupted, so you are not woken.
Can I take it on a plane?
Medistrom lists it as FAA compliant, and at 95 Wh it is under the 100 Wh carry-on threshold. Keep it in your carry-on, never in checked luggage.
