KFDReplacement Resmed AirMini Charger 24V 0.83A AC Adapter Compatible with Resmed Airmini AutoSet CPAP Power Cord 20W 38831 38839 CPAP Machine ResMed Air Mini Supplies Airmini Power Supply Cord Cable

Much smaller - thinner wire and smaller brick - which makes it fit into a smaller bag. Works just like the OEM.

This KFD Replacement charger for the ResMed AirMini works great! There are some differences between the original ResMed Charger and this one. For me, the differences aren’t significant, but they could be for someone else.1. The KFD is smaller and lighter than the original charger. KFD=140g (4.9 oz) vs ResMed =202g (7.1 oz) so, for a travel CPAP, saving 2.2 oz might be significant to some. See the photo for the size difference.2. Measuring from the machine to the plug pins, the KFD’s cord is about 4.5” shorter than the original ResMed charger cord. KFD= 71” Original= 75.5”3. The KFD cord is small and round and can wrap into a smaller space. The original has a flat strap-like cord.4. The KFD plug pins are vertical and the original KFD is horizontal (see photo.) Both are non-polarized (pins are the same size.)The charger worked fine with my AirMini. The connections fit snugly. Unless you need the extra few inches of length or flat cord that the Resmed offers, this is an excellent replacement charger and is lighter and smaller for travel.Full Disclosure: I received this product at no charge through Amazon's Vine program in return for writing an honest, accurate product review. Amazon's only requirement is that I review the products I order, not that I praise them. I don't pull my punches; if a product is bad, I say so, and if I love it, I say that. I have an obligation to tell you, the shopper, what I think so you can make informed purchases. I also believe sellers/manufacturers need to know if their product deserves 5 stars, or if they missed the mark, how they need to improve it.

Lost my charger for my Resmed AirMini after a recent trip, and this replacement charger works perfectly. Same size and configuration as the original OEM charger. Recommended.
