X10 Ace Mini Electric Bike Pump, 120PSI, 22s Inflate, Auto Stop | Portable Air Pump with Presta/Schrader Valve, for Road Bike, 1 PSI accuracy, 4.23oz, PSI/BAR

Sometimes a mistake proves how terrific a company is. I am a big cyclist who rides in a lot of different clubs. I am not savy enough to be able to change a flat tire on a road bike but with the Fanttik X10 Ace Mini Tiny Bicycle Pump and Gauge everyone is thrilled to watch how this amazing pump does all the work to inflate a tire to the correct PSI.I ordered 2 because I have 2 road bikes and one came without the Presta valve adapter. Just received that part a few days after my complaint. Thank you.

I have always been skeptical regarding electric pumps. I always carried a mini pump on my bike and didn't know why you would ever want one of these. Well my trusty mini pump fell out of my jersey pocket on a ride AND I had a puncture on the way home. My Local bike shop didn't have the mini pump I wanted and a friend swears by his mini pump. I originally got the Fanttik X11 and this converted me instantly. Easy to use, and I didn't have to worry about unscrewing my valve core when getting the tube attached to the valve. The down side of the X11 is that is was big, rather heavy and the tube to attach to your valve is permanently attached to the unit. Too big to fit into a saddlebag and was rather heavy to be in the back of your jersey pocket.I decided to leave that one at home for pre-ride fill ups and get this Fanttik X10 mini to carry on me during my ride. This is about half the size of the other one, and definitely lighter. It is about the same size and weight as my earbuds inside of the charging case. The battery isn't quite as good as the X11, but it is more than enough to charge it once a week and have it refill my tires before every ride. The pump is really powerful and generally fills my tires from 45 to 55psi in about 10 seconds. It is nice to have a digital PSI reading, as my hand pumps never had one. This was about half the price as my Lezyne Floor pump that is not collecting dust in my garage and this is very well built. If this dropped on the floor I would not be worried that it wouldn't still work. I also love that I don't need to use the hose for presta valves (you do need it for Schrader valves or if you are using TPU inner tubes with plastic valves as they can melt due to heat). Using this 4x per week I have never had this go down to the single power dot (there are 3 dots that light up depending how much battery you have left).It is very simple to use. Hold the power button to turn it on, select your exact PSI you want to use, and touch the power button once and it starts up. Once it gets to the PSI you selected, it will shut off on its own. You just need to push it on and pull it off of your valve. Nothing to screw in or a chuck to pull to lock it on your wheel. I have had no issue with it leaking air while attached to your valve. Now this is not quiet, but all e-pumps are pretty loud. The battery is nothing like the X11, but I expected this as it is half the size and a lot less weight. When I feel up my first tire the first battery light goes out. But I would still trust it if I had a flat. However if you are the type of rider that would just throw it in a saddle bag and not charge this for a month or longer, this may not be the option for you. I do about 4 rides a week and run my tires tubeless, so I tent to loose about 5lbs of pressure every 1-2 days. This is perfect for just getting that quick top off and be there in case of emergencies. I charge mine every Sunday night along with my bike computer and my bike lights and I feel like I still have about 50% of my power when I charge it up..

Where was this when i was buying gas cartridges that you have to discard even after a small use ...this is brilliant , weighs nothing in comparison and loads of battery power even after using on a flat tyre and no more gas cartridge frozen fingers beware in winter time ,this is so quick to use!

モーター作動時に爆音が出ますので室内では使えません。また屋外であっても人が多いところでは、周辺の方を驚かせてしまう可能性がありますから、周りに十分注意して使用してください。また、付属のホースを使用して空気を入れる際に、稀にチューブレスレディのバルブのコアを間違って外してしまう可能性がありますから、使用前に取り付け取り外しの練習をして使用することをお勧めします。上記２点があって星をマイナス２しました
