Fanttik X9 Ace Mini Bike Pump, 32s Fast Inflate Bike Pump with Gauge, 150PSI Electric Air Pump with Presta and Schrader Valve, Suitable for Mountain Bike, Road Bike, Electric Bike, MTB

This is a very handy and capable little inflater for my various bike tires. I have 4 bikes that have tire pressures ranging from 40 psi up to 90 psi. This little unit easily handles that psi range. I carry it on my bike rides - weighs less than two lbs, so not back breaking. Being able to easily change the compressor fitting from Presta to Shraeder is very handy, since I have both Presta and Schraeder valves on my various bikes. The hose fitting screws onto the tire stem, so there is virtually no air leakage (which I often get with a hand pump that clamps on). It takes about 2-3 minutes to pump up a partially deflated tire - not bad for such a compact unit (and less risk of the tire "exploding" if I used a regular compressor and overfilled). When you set the desired pressure, the unit automatically shuts off - so no risk of over-inflation. I can easily do about 6 tires on one battery charge. It typically completely recharges in a couple hours. Lots of awesome features on this product. My only complaints: the instruction manual could be a little more explicit, even the online version. It would be nice also to have a battery gauge to see when the battery should be recharged (I believe this is available on the heavier, more $$$ models). When you first use this, bear in mind that the tire pressure reading does not show up initially; it only shows up when you start the compressor (which would have been nice to learn from a better user manual lol). Overall, highly recommend this air pump.

EXCELLENT! It is not as small as the others on the market, but it is quieter, the battery last longer allowing you to inflate multiple flat tires on a long distance ride. I have a planned 9,500 mile ride with my 12 yr old son this yr around the USA. Flats are expected, and a hand pump is just not desired.It is a little heavier than the others as well, but I suspect that is also due to battery size and capability. I'll take it! Its an insurance policy on the cross country bike tour.I mentioned the size at the beginning as it being bigger then the others on the market. I need to point out that while this is the biggest I am aware of these little compressors, it is still small enough to fit a top tube pack. It is a bit heavy, so i would not want it in my pocket all day, but it certainly will fit, just not as comfortably as some others.At the end of the day, I chose this compressor because of PRICE. It does everything I need it to do. I am not a competitive rider, so I dont need to inflate in 30 seconds and often enjoy the extra break time to catch my breath to fix things if needed, so if it takes me 30-90 seconds longer to repair a flat, I am not concerned, you might be!Overall, I am really happy with this product. it is a well made product.USB-C charge port with a slow flash LED charge indicator and steady LED when fully charged.Digital display/ Programmable up to 150 PSIAuto-shutoff once at proper PSI.Shrader and Presta valve capable/ready

It's a bit slower than its larger and more versatile brother - but it works well - like really well. I think it's a bit heavy to carry with you though, while riding which is a downside (that's why it isn't 5 stars). Battery is good to fill 4-6 tires on one charge (700c road cycling - up to 100lbs without issue). Built-in support (without anything to lose) Presta/Schrader valve stem. One small critique is that the angle of the attachment doesn't allow you to set thee pump down as it's doing its thing as it is a bit rigid. but it is quick and the auto-off feature and being able to set the exact pressure you want - these features are clinch. If it's on sale - this is a must-buy - if regular price - if you can swing it and if you regularly have to top off your bike tires - this is a REALLY nice to have.

Works great! I use it to fill up my tires when my bike is in the basement on the trainer, fast and easy. A bit heavy but will probably replace the CO2 refill system.

The Fanttik X9 Ace Mini Bike Tire Pump has been an absolute game-changer! It's incredibly compact and lightweight, so I can easily carry it on my bike during rides without adding any extra bulk. I've used it for my own tires, and it has worked flawlessly every time—pumps up the tire quickly and efficiently with minimal effort.What’s even better is that I’ve been able to help other cyclists on the road who have had flat tires. This pump has enough power to handle larger tires and is super easy to use, making it a great tool to have in case of emergencies. It’s durable and well-built, and I feel confident that it’ll last for many rides to come.If you’re looking for a reliable, portable bike tire pump, I highly recommend the Fanttik X9 Ace—it’s small in size but big on performance!
