Muc-Off’s AirMach Electric Mini is constructed from aircraft-grade aluminum and includes a removable silicon case. The pump charges via USB-C ports and works with Presta, Schrader, and Muc-Off’s Big Bore valve stems. Although it lacks a digital display screen, it is the most affordable and one of the smallest electric pumps in the group. For those who would like a digital display, Muc-Off does have a newer model with a screen which retails for $140.

The Trek Air Rush mini electric pump was far and above the most accurate pump of all those we tested. While the other pumps were typically a couple of PSI off, the Air Rush inflated our test tire to within 0.1 PSI of our desired setting. While being the most accurate of all the electric pumps, the Trek Air Rush also has one of the longest battery lives, making it a unit we’d think very hard about adding to our tool bag.

The Fix Eflator Mini takes up minimal room in your pack while weighing roughly the same as two CO2 cartridges. The Eflator will have you back riding in approximately one and a half minutes, but note that it was a couple of PSI over our desired target. Like many of the pumps in this lineup, Fix designed the Eflator to work with both Schrader and Presta valves, and they also include a needle for ball inflation.

The Cycplus AS2 Pro is easily one of the smallest and lightest mini compressors in the group. It is also the fastest by a long shot, beating all other pumps by 33 seconds on average. However, speed comes with an accuracy penalty, as the Cycplus AS2 Pro was 2.5 PSI under our desired target. Once you know the units accuracy discrepancy however, it would be easy enough to add 2.5 PSI to your selected inflation number and rest assured you’d be pretty dialed. Despite the accuracy, we like the units size, speed and sound.

The Viair Recon Mini features a digital display and the ability to preset a desired PSI, allowing the pump to stop once it reaches that pressure automatically. The Recon Mini was on the louder side, at 55.6 decibels, and took just under a minute and a half to achieve our desired 25 PSI.

Topeak’s E-Booster was the largest and heaviest mini compressor out of the group. Despite its stout size, it can still easily fit into a hip pack, although in-frame storage (depending on the bike) might be out of the question for this one. The E-Booster is also the most expensive pump in the lineup.
The Wolf’s Last Word
Different pumps had some distinct features that set them apart. We loved the speed of the Cycplus as well as the accuracy and ease of use of Trek’s Air Rush. Our Muc-Off pump didn’t have a display screen, but newer options do. If we’re being honest, we’d be happy to ride with just about any of these in our hip pack but we felt that the Cycplus AS2 Pro would likely be our pick as it was compact, fast and quiet. That being said, they all got the job done just fine, we’d suggest you look for what is on sale and find a good deal on whichever unit excites you most.
