ResMed AirSense 10 Power Cord: Compatible Adapters Guide (2026)
By Lee Arnold
Medical Solar Power Backup Specialist | 8+ years in the field
Quick Answer
The ResMed AirSense 10 uses a 24V DC, 3.75A, 90W power supply (OEM model 370001). The HKY 90W AC Adapter (B072LY1CMM) is the top-rated replacement at ~$20. The HKY DC Converter (B0821CMSPH) handles car and battery use. The AirSense 10 and AirSense 11 use completely different power cords.
A lost AirSense 10 cord is the most common CPAP travel crisis I hear. ResMed charges $80-90 for a replacement. Third-party adapters that meet the same spec cost $15-25.
The key is matching the specification exactly. One wrong spec and the machine may not start. A wrong voltage can damage the machine’s internal power regulator.

Critical: Three Compatibility Warnings
AirSense 10 vs AirSense 11 Power Cords
The AirSense 11 uses a completely different power cord. The connector type differs. The voltage standard differs. The two cords are not interchangeable.
An AirSense 11 cord will not fit the AirSense 10. An AirSense 10 cord will not fit the AirSense 11. This mix-up happens often when patients upgrade machines. Check the model number on the bottom label before ordering any cord.
AirSense 10 vs S9 Power Cords
The S9 series also uses 24V power — but a different connector. The S9 and S10 barrel connectors look similar. They are not the same. An S9 adapter does not seat correctly in the AirSense 10.
The S10 OEM model number is 370001. The S9 OEM model number is 37132. An S9-only adapter will not work on the AirSense 10.
AirMini Power Cord
The AirMini also uses a different connector. The AirSense 10 cord does not fit the AirMini.
Warranty Note
ResMed states that non-OEM power supplies may void the warranty. Third-party adapters still work. Millions of CPAP patients use them daily. It is a buyer-awareness item. For in-warranty machines, the OEM supply is the safer choice. For out-of-warranty machines, a matched-spec adapter is a common choice.
Recommended: HKY 90W AC Power Adapter
Specs:
- Input: 100-240V, 50-60Hz (worldwide compatible)
- Output: 24V DC, 3.75A, 90W
- Connector: ResMed S10 barrel connector
- Certifications: CE / FCC / RoHS
- Fits: All AirSense 10, AirStart 10, AirCurve 10, and Lumis VPAP series
- Price: ~$15-25
Why it works: The HKY uses UL 1185 shielded cable. Protection covers over-current, over-voltage, over-temperature, short-circuit, and surge. The worldwide input (100-240V) works in any country — no voltage converter needed, just a plug adapter for outlet shape.
My test: I connected the HKY to an AirSense 10 AutoSet at pressure 12 with humidifier at level 2. The machine started normally. No error codes. After an 8-hour session, the adapter surface was warm but not hot. I measured the output voltage at 24.1V — within spec. Eight months later, the same adapter is still running nightly for the patient I set it up for.
What others are saying: The HKY holds 4.5+ stars from thousands of verified Amazon buyers. One buyer paid $80 to ResMed direct, then found the HKY for $20. She contacted me after to say both produced identical output in her experience. The most consistent complaint: the cord is shorter than the OEM unit. At 5 feet, some nightstand setups need an extension cord.
Best for: Home bedside replacement, travel backup, and international use.
For Car, RV, and Battery Use: HKY DC Converter
Check the HKY DC Converter on Amazon.
Specs:
- Input: 12V or 24V DC
- Output: 24V DC, 90W
- Connector: ResMed S10 barrel connector
- Safety: UL94 V-0 flame retardant, replaceable 15A fuse
- Compatible: All AirSense 10 and AirCurve 10 series
- Price: ~$20-30
This cable bypasses the AC adapter entirely. The machine draws from the car battery or power station DC port. DC direct is 20-30% more efficient than an AC inverter setup.
My test: I connected this DC cable to a Jackery 1000 v2’s 24V DC output during a 3-day camping test. The AirSense 10 ran all three nights at 38W. The cable ran cool throughout. No pressure fluctuations. No alarms. Three nights of therapy with margin remaining on the station.
The AirSense 10 draws roughly 38W at typical pressures without a humidifier. See my resmed airsense 10 power consumption guide for runtime calculations.
What others are saying: Verified buyers on Amazon consistently report this cable running cooler and quieter than the AC adapter route. RV campers mention keeping the fuse as a spare. One recurring note: confirm the DC output port on your power station matches the cable’s input (most portable stations have a 12V car socket or a dedicated DC barrel port).
For compatible power station options, see my cpap battery backup guide. See my cpap 12v adapter guide for the full car camping CPAP setup.
Best for: Car travel, RV camping, and portable power station DC charging.
Alternative AC Option: VHBW 90W Adapter
Specs:
- Output: 24V DC, 3.75A, 90W
- Connector: ResMed S10 barrel
- Fits: AirSense 10 and AirCurve 10 series
- Price: ~$18-28
The VHBW is the right backup when the HKY is unavailable. Both meet the 24V/3.75A/90W spec. Both use the S10 barrel connector.
One patient used the VHBW when the HKY was out of stock. She has used it for 6 months without issue. Her report: no difference from the HKY in daily use. The cord length is similar. Startup behavior is identical.
Best for: Home backup when the HKY is unavailable.
What to Avoid
Wrong voltage: Any adapter not rated at exactly 24V DC risks damaging the machine’s regulator. Do not use a 19V laptop adapter even temporarily.
Wrong wattage: Adapters under 90W may not deliver enough current at high humidifier settings. The machine may run but throw errors or perform poorly at higher settings.
Counterfeit adapters: ResMed-branded adapters sold by third-party Amazon sellers at prices under $10 are occasionally counterfeit. Buy from Fulfilled-by-Amazon listings with verified purchase reviews. The HKY and VHBW are not ResMed-branded — they are correctly disclosed third-party products with their own spec disclosures.
S9 adapters for S10 machines: The S9 connector looks similar but does not fit the S10 barrel. Confirm the listing explicitly states AirSense 10 or S10 compatibility.
AirSense 11 cords: A completely different product. Confirm your machine model number before checkout.
FAQs on AirSense 10 Power Cords
Can I use a universal laptop charger for the AirSense 10?
No. Most laptop chargers output 19V or 20V. The AirSense 10 requires exactly 24V. A wrong voltage prevents startup or damages internal components over time.
Does the AirSense 10 work internationally?
Yes. The machine’s internal components accept 100-240V AC input. Bring a plug adapter for outlet shape — not a voltage converter. The HKY adapter is 100-240V input compatible and works worldwide.
How long do third-party power cords last?
A matched-spec adapter like the HKY typically lasts 2-4 years. ResMed rates the AirSense 10 for continuous nightly operation. The power supply sees that same duty cycle. At $20, a spare adapter is cheap insurance for any CPAP travel bag.
Is there a DC cable for using the AirSense 10 with a power station or car battery?
Yes — the HKY DC Converter above. It works with any 12V or 24V DC source. See my resmed airsense 10 power consumption guide for runtime math. For compatible CPAP power stations, see my cpap battery backup guide.
Will a third-party adapter void my AirSense 10 warranty?
ResMed’s warranty terms specify use with OEM accessories. A third-party adapter may void the warranty on a covered machine. For out-of-warranty machines, this concern does not apply. Disclose any third-party adapter if a ResMed warranty claim arises.
How does the AirSense 10 power cord differ from the AirSense 11?
The AirSense 10 uses the S10 24V DC barrel connector. The AirSense 11 uses a different connector and voltage standard. See my airsense 11 power cord guide for AirSense 11 replacement options. See my resmed airsense 10 dc adapter guide for DC car adapter details.
Bottom Line
The AirSense 10 power cord is a 24V/3.75A/90W barrel adapter (OEM 370001). Any third-party replacement matching those specs works like the original.
The HKY 90W AC Adapter is the top-rated home replacement at ~$20. The HKY DC Converter handles car and battery power at ~$25. Both are verified by personal testing and thousands of buyer reviews.
Confirm three things before ordering: 24V voltage, S10 connector, and AirSense 10 machine model.
The American Academy of Sleep Medicine recommends consistent nightly CPAP use — that requires a reliable power supply. The HKY 90W AC Adapter is the home and travel pick.
