Works great! But, Schrader adapter component seems to be problematic. Read review for details.

I have both Presta and Schrader tires. Initially, I tried using the red Presta attachment. Very intuitive. I hooked it up, charged, and it worked as advertised. I then tried the Schrader. I spent about 15 minutes trying to screw the white Schrader attachment on to my valve. I could never get it to thread. I tried several times over and over, then realized what might be the problem: the Schrader attachment had no threads! So, I started the return process to get a replacement. The new unit arrived a couple days later. But before using the new unit, I checked to make sure it had threads on the Schrader attachment. It did. So, I tried again. But, I could never get the new red Schrader attachment to thread on to my tire stem. After about 10 minutes of trying, I looked at the attachment. After all my attempts, it now had no threads. I know how to carefully thread screws, but this simply would not thread on. And eventually, all the plastic threads wore off the new red Schrader adapter. I was about to return this one as well, but then decided to conduct an experiment. Turns out, the included extension hose has the exact same thread as a Schrader. So, I screwed the extension hose directly onto my Schrader tire stem. Perfect fit. There is no pin or stub in the extension hose to open the valve, but the pressure from the pump was sufficient. I was able to quickly pump up both my front and back tires using only the extender attachment hose. I'll probably not return the original since I decided I need 2 of these anyway. Eventually I'll get charged for the second unit, but I'm cool with that. So, not sure if it's a defect or I'm doing something wrong, but the red Schrader adapter doesn't do anything except wear out.

Also, the included extension hose works great to extend the Presta attachment as well. The documentation is a bit misleading, indicating the extension hose is only for the Schrader. But I found it awkward connecting the pump directly onto the Preseta tire stem. So, I use the extension hose for both types of stems. I simply don't use the red Schrader attachment on my tire stem when pumping a Schrader, since it doesn't seem to work at all for that.

Hope others find this useful, since the device works very well. Just that little issue with Schrader!
I've attached images of both failed Schrader adapters.

Updated to 5/5 after not using provided adapter

Reviewed in the United States on August 6, 2025

Edit:
There are 2 different products being reviewed here together. Ultimately found that if you just use the tube for shrader valve, not the white adapter, it screws right in to the valve and works perfectly. Presta works with adapter perfectly as well.

Works great for tubeless presta valves on my mtb. Pushes on, holds, it's great. Little noisy as others stated and it definitely gets hot. But shrader valves on my gravel bike, forget it. It leaks out more air than it lets in. There's no way that I've found to push it on and have it stay on with a shrader valve. If I hold it as still and pushed in as I can, I can hear air still leak out and I can't build up pressure past 25. Useless. Wish the adapter were threaded so I could just screw it on to the valve and let it fill. Only works for half my applications , so 3/5

Great for Airplanes

Reviewed in the United States on October 25, 2025

I'm very impressed after my first few uses. I'm using it as a travel compressor in my 1971 Mooney airplane and it makes quick and easy work of the tires up to their rated 30psi. It also works great in my mountain bike. It is noisy, but so are all other small compressors I've ever used, but this one is 10x smaller and completely portable. Inflation speed is fine for small low pressure tires. I haven't tried it on a road bike yet to 100+psi, but I'm sure that will work well too.

Great 127g 95db Mini Pump

Reviewed in the United States on February 15, 2026

Great little inflator! Ran it through some paces and pulled the back cover off to see some specs and take some photos. Here's the results:

– 85db at ~1m distance when running. It's LOUD but not horrific.
– 126.88g, measured. Not 108g as claimed. (vs ~80g for CO2+adapter)
– Motor is a brushless motor, amazing to see these in consumer devices now! This explains how it can be so efficient and powerful.
– Battery is 500mah 2S 7.4V 3.7Wh (equivalent to 1000mah if 1S)
– Flashlight is handy but only barely.
– Best thing: unlike CO2 this is a real *tool* you can use any time and just charge up later. More like a wrench set than a disposable one-time-use emergency item.

9/10 would recommend and buy again. I'll update in the future after more real world testing.
