External 90 Watt Power Supply for ResMed S9™ Series CPAP and BiPAP Machines

Good replacement for the original.

The staff that helped me was incredible, power supply worked great

No issues at all. Exactly like the one I was replacing. Glad for the photo of the plug so I could confirm it had the right kind of connector. No Rx confirmation needed, and it arrived right on time.

100% Highly Recommended... Excellent Prices.

My resmed S9 battery takes this power supply to charge, and since I’m passing my old machine on I need the power supply to recharge the battery that I’m keeping. Tried it and works well. At this price you should have a spare in case of power spikes. How many computer power supply’s have you bought over the years? Think about that!

Everything I ordered was first-quality and brand-new. Fabulous service, an excellent experience by every measure.

This product works good but I had to purchase bumpers for the bottom to keep it from sliding off of the nightstand.

was what I wanted, the price was good, and came on scheldue

I purchased this unit to replace the power supply that came with my ResMed S9 many years ago. (That one finally stopped producing power.) The replacement is similar to a power supply I bought for travel purposes a few years ago. Both of the newer units have several improvements over the design of my original power supply: 1) They are shorter and a bit lighter, so they're more compact and will fit in smaller places. 2) This new design has a Velcro-type strap built into the "brick" that is very convenient for storing the power supply if you're taking it out of service. With the built-in strap, you can secure the folded cords to the power supply so that they don't tangle and dangle. The high-voltage cord that runs from the power supply to a wall outlet is approximately 5 feet 9 or 10 inches long. It is detachable from the power supply. The plug that plugs into wall outlet is the standard 2-prong US-style plug. The low voltage cord that runs from the power supply to the CPAP unit is approximately the same length as the high-voltage cord, giving a total span of almost 12 feet from the wall plug to the CPAP unit. The low voltage cord is permanently attached to the power supply. The plug that plugs into the CPAP is identical to the plug it replaces: an elbow-style 3-pin connector. The power supply does exactly what it's supposed to do: Drop the voltage and condition the power. It appears rugged and well-made. The strain relief for the low-voltage cord appears well-designed and identical to the one on the original. I'm very pleased, though not surprised. CPAP.com's products have always lived up to expectations, and I've always been happy with ResMed. --LM, a 25-year CPAP patient and a happy customer of CPAP.com.
