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

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

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!

Does the job of pump and pressure reader quite effectively. Just a bit heavy and I think twice before lugging it with me on a ride. One star off for the weight... otherwise I'm loving it.

This unit is great for managing tire pressure on bicycles. It's relatively inexpensive, does its job well, charges with USB-C, and the battery lasts many, many applications. I've used it over a dozen times before needing to recharge. Small enough you could put it in a jersey pocket or bag if you want.

So far, great little pump. I also have a larger Xiaomi pump that is similar. These were the only two I found that had well-designed integrated presta adapters, rather than the classic little brass ones that screw onto the valve not the pump and always get lost. I used this guy to pump two motorcycle tires from 26psi to 32psi, and two gravel tires from dead flat to 50psi, and it had the battery for that. I didn't keep going with other tires to see how far the battery can go, but this appears to be enough for my usage. I think it would reinflate a single truck tire from flat (which is my worst case usage), and definitely is enough to top off or reinflate my smaller tires.

Great little pump. I use it mostly for topping off tires. Road bike tires such as 28mm tire take about one second for each pound of pressure. Large tires for mountain bikes you can triple that. So if you are pumping up a totally flat tire it will do it just fine just takes a little time. A hand pump will still be faster.Speed aside this is a great pump to have on hand for keeping tires up to pressure between rides. It is small and compact easy to use. I especially like being able to dial in the pressure you want and it auto shuts off when the pressure is reached. Same exact pressure every time. I think is a little big and heavy to carry with on a road bike, but if you are touring around or commuting I think it would be fine when weight or bulk is not an issue. It will be my pump of choice to take on a multi day bike tour along with a couple CO2 cartridges.

Love this bike pump. It's a must have in my Onewheel bag. Not too loud, quick for it's size, and programmable. It has a premium feel to it and super compact.

It works so well that I ditched using my air compressorVery practical, easy to useThe screw on connector (to tire valve) seals the connection so no leaks. I have bikes with both types of valves and it works great on bothInflates to high pressure (100+ psi) for my road bike tires with no problem. Easy to program exact pressure you need and now I don’t have to keep checking how much pressure I have in the tire, it simply stops automatically!Compact and relatively light you can take it with you on your rides which now I do always; it even let me help a fellow cyclist one day that needed to inflate his tire on the trailBattery lasts long time and permits quite a few tires inflations before needing to be rechargedDefinitely recommend !!
