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

I'm only a few days in, but this works incredibly well. I did not initially read the instructions, so I will stress that you must screw the head onto your valve to get a good enough seal. This is not like a floor pump where you can just press it on. Overall, the battery is holding very well and gives you a number of inflations. It is a little heavy and loud, but for the price, it's nice to have the peace of mind and not have to spend 10 minutes cramping your forearms with a mini-pump when you get a flat out on the road. The speed doesn't appear to be too bad, as I've been getting about 1psi every1-2 seconds for a 700x39c tire. I know it's a little bigger than some of the other inflators out there, but I think the increased battery capacity is worth it, and I don't think it's unreasonable to ride with this in a jersey pocket.

This is a good product like other Fanttik products I own. Earlier I gave it a bad review but it was my fault as i was not matching the right kind of adaptor with the valves. It’s easy to use and inflates tires within a couple minutes from 0 to ideal psi. I wish it came with a longer hose so it was easier but use, but not a huge deal.

I use this for my Motorcycle despite not being advertised for that use. This pump has been excellent at keeping my tires at the proper pressure with temperature shifts. My only complaint is that it can be difficult to get the nozzle on rear tire's valve due to a short stem and the bikes belt/ chain/ brake rotor being in the way. I probably wouldn't expect this pump to fill from flat to spec, but its more than capable of topping off or refilling a plugged leak.

I watched several reviews of compact electric pumps for travel and chose this slightly larger one because it can fill my tire up to 7 times or more, most others only manage less than 3. Despite being larger, it's still compact and can handle the 80 PSI my tires need.I really like the secure connection, it seals well, and hardly any air escapes when attaching or removing it. I like it doesn't have the high pitched sound of other mini pumps.My only complaint is that the power button can be accidentally pressed in a bag. It takes two presses to turn on, but it still got activated once while in my backpack.

The PSI reading is way off. I set it to 20 psi to inflate my bike tire. It immediately turned off because it was showing my flat tire had a psi of 67. I had to increase the psi to 150 in order to inflate my tire.*Update*I am changing my review to 5 stars. It turns out I was supposed to flip the valve to the Schrader valve. After sending the original pump back to Amazon, Fanttik customer service contacted me and offered to replace it for me. After I received it, I was having the same issue but they followed up with me and had me flip the valve to the correct side and it started working perfectly. This product is great and their customer service is outstanding. I will be buying from them again.

Set it to a psi and it goes to that psi. Kinda heavy, usb-c charging port. Not too loud but ot is a pump so it is noisy. Easily switch between shrader and presta, seriously, I did it yesterday to fill my sons tires. I will carry it in my backpack while mtb downhill riding. No idea how long the battery will last, should be fine since I will only be topping off when I lose some pressure on the trail.

This is almost an excellent pump. It would be outstanding if I could read the display.Whoever chose to use smoked plastic over the display should rethink that decision.I’ve used the pumps a bunch of times and it works wonderfully, but I’m always searching for a dark place to see the display. Fortunately I use it on the trails where shade is available. In an unshaded area, the display is invisible.It functions perfectly, but the display is a total letdown.The attached photo is an example of the display in a shaded area. Look closely, it’s turned on and displaying 00.
