Muc-Off has expanded its inflation range with the AirMach Electric Mini Inflator Pro. Designed for riders who want the easiest and most precise way to inflate their tires, this next-generation electric inflator builds on the success of the original AirMach Electric Mini, packing even more features into a sleek, pocket-sized design.
Small in size but mighty in performance, the AirMach Electric Mini Inflator Pro delivers rapid inflation up to 120psi. Weighing just 122g (142g with case) and measuring 48.5 x 64.5 x 28 mm, this mini powerhouse is easily stowed in a jersey pocket or bike bag, ensuring it’s always ready when needed.
Tested weight => 142g with case, 121g without case
One of the most significant upgrades over the first-generation model is the integrated LED display, which provides real-time readouts of air pressure and battery level, allowing riders to dial in pressures with precision. With a new 450 mAh lithium-ion battery, the Pro version can inflate up to four road bike tires on a single charge and recharge in 30 minutes via USB-C.
Tested => Inflated four 29 x 2.5″ mountain bike tires from flat to 28 PSI!
The AirMach Electric Mini Inflator Pro is the latest addition to Muc-Off’s extensive inflation line-up. Whether riders prefer a manual pump like the AirMach Mini (81g) or AirMach Carbon (132g), the speed of CO2 inflator kits, or the all-in-one puncture repair and inflate power of BAM!, Muc-Off has a solution for keeping riders pumped in every situation.
The AirMach Electric Mini Inflator Pro is priced at £100 / €125 / $155 and is available worldwide through the Muc-Off dealer network, select e-retailers, and directly from www.muc-off.com.
Impressions
The AirMach Pro is a compact, light, water-resistant, fast-inflating, and powerful mini battery-powered tire inflator.
Weight-wise, the AirMach Pro (142g with case, 121g without case) falls within the range of most hand pumps, although a lighter option is available with smaller mini pumps. One thing I don’t miss is that the seemingly endless pumping required with a hand pump is no longer necessary. Hook up the AirMach Pro, set the pressure, push the button, and, in no time, your tire is set!
The small size makes it easy to toss into a pack or frame/tool bag on your bike, though the robust aluminum body is centrally heavy, so it’s not ideal for a jersey pocket.
Measured size
- 1.9″ x 2.6″ x 1.1″/48.6mm x 64.6mm x 28mm
Tap the side-mounted power button, and the bright LED screen lights up. It was enjoyable to have the LED screen, which displays the battery level, the pressure unit (PSI or BAR), and the desired pressure level. Set the pressure using the + and – buttons, attach the nozzle to the valve, and then press the power button again. The unit inflates the tire and shuts off when the desired pressure is reached. The battery shows three segments when fully charged.
I was able to inflate four 29 x 2.5″ mountain tires from flat to 28 psi, taking around 60-70 seconds each time. I didn’t have any high-pressure road or gravel tires to test, so I am unsure of those statistics. If you are inflating several flat or near-flat tires, allow the unit a short time to cool off, as it automatically shuts off if it overheats. During the latter part of my test period, I was using the new Clik Valve Core system, so I attached their adapter head to the AirMach Pro extension hose. I found the extension hose easier to use for inflating any tire, and it’s required when filling plastic/resin/TPU tubes to prevent overheating the fragile valves.
Measured weights:
- AirMach Pro with case 142g/121g without case
- Silicone case 21g.
- Extension hose 14 g.
- Presta hose adapter 7g.
- Main red nozzle 7g.
The 450 mAh 7.4V lithium-ion battery is relatively long-lived, and since I only use the AirMach Pro to top off tires, I rarely charge it, typically waiting for many months. When charging via its USB-C port, it takes about 30-45 minutes, depending on the power source. If you are out in the field, it’s easy to plug in the USB-C cable and charge it from your vehicle or a portable battery pack.
I found it somewhat hard to locate the side-mounted power button, especially with the cover on, which made the click indistinct. I have grown accustomed to pushing the button, but it always feels like I’m blindly reaching to the side to initiate, especially during the inflation step.
It won’t truly replace my trusty floor pump, though. Even when I am at my truck, it’s easier to grab the AirMach Pro and top off my tires. It’s not a replacement for a heavy, large-frame pump or multiple CO2 cartridges, though I was never a fan of the latter, as they can’t be tailored to the desired pressure, can be leaky, and can cause frostbite. The one thing the AirMach Pro can’t do is pop a stubborn tire bead up onto the rim’s internal shoulder, as it lacks the air throughput that air compressors and high-pressure air chambers excel at (and, on occasion, CO2 cartridges). Let’s be honest, it was never designed for something like that.
It is a bit noisy by grand scheme standards, but it’s a minor annoyance for a compact, portable battery air inflator, and I never find it obtrusive outdoors.
You can save a bit of weight by not using the silicone cover (-20g), but it provides extra protection, keeps the metal unit quiet when it gets banged around in a pack/bag, and prevents heat from transferring to your hand if the unit gets hot.
The complete kit includes the inflator, silicone case, storage bag, USB-C cable, toy nozzle, ball needle, extension hose, Presta valve converter, spare valve seal, and O-ring. I didn’t really use anything but the main nozzle, extension hose (with Presta & Clik adapters), and the spare parts. I eventually only carried the extension hose with the appropriate adapters, dropping the red nozzle from my repertoire.
Air Nozzle Fittings
- The main red nozzle default is Presta valve.
- Remove the top of the red head unit and internally convert it to a Schrader valve.
- Remove the red head unit, attach the extension hose, and the default is a Schrader valve.
- Add the Presta valve converter to the end of the extension hose.
- Add the Clik valve converter to the end of the extension hose.
Bottom Line
I no longer carry a mini hand pump since the Muc-Off AirMach Pro has proven to be robust, fast, long-lasting, and easy to use. Turn the unit on, set the desired pressure, attach it to the valve, and press the inflate button. The unit will shut off automatically when the pressure is reached. Easy peasy! Top off tires, or fully inflate four tires from scratch.
