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 bought this for my road and ebike, but had to use it on a car tyre recently and it did a great job. Easy conversion between presta and Schrader, which is a huge + for me. Heavy, but that's probably because it has a good battery. Will easily fit into a saddle bag

I'm a cyclist and I love the way this little pump will show psi. If you're using the Presta side (just unscrew and flip the head), no problem. But I have some uses where I need the Schrader side....not so easy to thread onto a Schrader valve. Maybe it's just me. That is the ONLY reason why I gave it 4 starts. I won't ride without it. But keep it charged up. Nice design and reliable.

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.

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.

If you want to inflate a Presta valve you must insert into the valve and screw it in the valve too. It will not work otherwise, it took me a while to figure out. Even after writing to their excellent customer service, i think they have instructional language challenges, they could not explain this. The machine works well, just needs better instructions. Their customer service is excellent, very attentive. I hope they read this message and fix the instructions.

Works as advertised. I love this thing. Streamlined my pre-ride workflow and makes it’s so easy to get consistent tire pressures and ride quality.

Works great. It gets near daily use in my household. It survived a CX season in my back pocket at some cold and wet races. I don't take it with me on rides, it's a bit heavy for that, but could easily fit in a jersey pocket or a larger saddle/top tube bag.
