HKY Replacement Resmed AirSense 11 Power Supply 24V 65W AC Adapter

What buyers think

Buyer-review evidence highlights a consistent theme: the adapter is a good fit for AirSense 11 users, with reports of the machine starting normally and the connection not overheating during use. Reviewers also mention convenience for travel, using the smaller or alternative power supply in a travel case as an extra at another location. Overall, the review pattern points to reliability for the intended machines, but it does not provide much detail about long-term durability beyond day-to-day operation.

Compatibility and key specifications

When you’re replacing a CPAP power supply, matching voltage, wattage, and connector fit are the two biggest factors. This HKY unit is rated for:

• Input: 100-240V, 50-60Hz
• Output: 24V, 2.71A, 65W
• Connector type: barrel connector, with a DC connector intended to match the pictured/compatible design

Supported devices: ResMed AirSense 11 CPAP machines (including AirSense 11 AutoSet and AirSense 11 Elite) and ResMed AirMini Auto portable CPAP machines.

Not for these models: ResMed AirCurve 11 series bilevel machines (including VAuto, ASV, and similarly listed variants), and it is also not intended for ResMed S9 or ResMed S8 series devices.

North America power cord: It includes a US and Canada style AC power cable.

Why this power supply is a good backup option

If you frequently travel, keep a spare at work, or just want a redundancy plan for your nightly therapy routine, a replacement power brick can reduce stress. This model is specifically positioned as an AirSense 11 and AirMini Auto power supply replacement, and buyers repeatedly describe it as straightforward to use with a good plug fit, making it practical for “grab-and-go” setups.

Safety and protection features to look for

Power supplies for medical devices are not the place to gamble. This HKY adapter lists multiple protection and safety-related design points, including overload and short circuit protection, overheat prevention, and electronic shielding. It also notes flame-retardant-grade materials (UL94 V-0 grade) and electronic protection (OVP, OCP, SCP) as part of its design approach.

As with any replacement adapter, the best way to reduce risk is compatibility checking, using the intended cord version, and verifying the connector matches your device.
