FanttikX8 Ace Bike Pump 150PSI Fast Portable Tire Inflator, Cordless Rechargeable Electric Bicycle Air Pump, Auto Stop, with Presta and Schrader Valve for Fat, Mountain Bike, City Bike, Road Bike

I like the form factor for this pump. I use it to air up my roadie to 105 psi and my MTB to 22 (both Presta valves). It also works for Schrader. It does both super well and I like that it has presets that save those values. I just select the bike type and hit go and it does the rest. It has the capacity to air up several tires before needing to be recharged. It is small enough that I keep it in my bike bag at all times. It is super nice to be able to top off my pressure whenever it is needed. My first one lasted about a month, just past the return period for Amazon, but I contacted the seller and they sent me a new one super fast for no charge. Great customer service.

This Fanttik X8 Ace pump is one of my best cycling purchases. It’s compact, lightweight, and extremely powerful, inflating road and mountain bike tires effortlessly to accurate pressures (up to 150 PSI!). Cordless and rechargeable, it's incredibly convenient for on-the-go inflation or emergency repairs. The digital display is intuitive and precise, with an auto-stop function that prevents over-inflation. Compatible with both Presta and Schrader valves, it’s versatile for any bike. The build quality feels premium and durable—perfect for everyday commuters, trail riders, or anyone needing reliable tire maintenance.

I have an electric skateboard with all-terrain pneumatic tires (200x50mm tubes). The rechargeable pump for my car works well for at-home inflation, but its much too big to carry as part of skateboarding kit. This pump is just as functional (USB-C charging, emergency light, and settable pressure). Just like the full size pump, you set the pressure and inflation stops at the target pressure. In a way, it's better than the full-size pump, which uses a lever-style quick-release chuck, which loses a little bit of air when you detach it from the valve. Negligible loss for a high-volume like an automotive tire but more significant for a lower volume tire like a pneumatic skateboard tire or even a bike tire. The screw-on style chuck of the Fanttik pump has proven lossless so far, maintaining the target pressure when detaching from the valve.There are different modes such as ebike, city, etc, but the target pressures don't really make any sense and I've ignored them. It's much better to simply know your target pressure and manually set it. Used that way it's quite simple to use.I have only tried this with my skateboard tires and no problem with all four wheels...plenty of battery left over. However, I haven't really tried to test just how long it will go before running out of battery...or shutting down to prevent overheating the pump.The instructions, which are competently translated into English, are poorly organized with needed instructions scattered through the instruction sheet. Thankfully it's pretty short and quick to scan the whole thing. In addition, there are no clear instructions on charging the pump. The pump has a four segment battery indicator and it appears that each segment blinks as the pump charges. I believe that when all four segments are lit and not blinking the pump is fully charged, but that's not stated anywhere in the manual. I believe that's a pretty reasonable and intuitive guess, but it would have been nice if it were written in the manual.

This pump is great to pack on my motorcycle for trips. Small and powerful. I've been testing it before my long trip and it holds a charge for over a month. I got to use it when I pulled the riding mower from winter storage, it filled the tires fast

This pump absolutely sucks. It can't even pump up my touring bicycle trailer which are only 35-55 psi tires, let alone my recumbents tires which I like at 80psi. It's supposed to be able to go to 159psi.I would return it but I didn't try it out until this morning and I got it in January and this is April.

The best by far

Disappointment level high! I got this to keep in my pocket on a bike ride. This thing is huge and weighs a lot. No way can I take this on a ride without a backpack or panniers. Hoped to use it on local rides. It will sit in the garage instead. It might be great if you are in a support car for an event.My star rating has nothing to do with its capability. It will be unused.

Works very well. Needs recharging after 2 bike tires, but charges quickly.
