CYCPLUSTiny Pump Bike Pump Portable Ultra-Mini 100PSI Electric Bicycle Pump Type-C Rechargeable Battery, No Pressure Display(Winner of The EUROBIKE Award 2023)

Wow! this mini pump works great. It filled a 700x26 Pirelli tire/tube from very low psi to 70psi in less than one minute. It is small enough to fit in my under seat bag, which is a small bag.

Awesome little gadget! It's much smaller than my excellent Cannondale mechanical mini pump and easily fits in my seat bag. It's also a touch lighter (116 g for the Cycplus pump vs 119 for my mechanical pump).The unexpectedly cool thing is how easy and quick it is to use. I unzip my seat bag, pull out the pump, press the button to turn it on, just press onto the valve, then double-press it to start inflating. I feel this is much quicker than undoing the strap of my mechanical pump and extending the short inflating hose. From memory, it takes 20 seconds to completely inflate my 700c x 32 tires to 60 psi.In fact, I had a slow leak in a tire recently and I could re-inflate it and get back on my bike while waiting for a red light to change. I probably inflated the tire from 25 to 50 psi.Of course, since it's battery-powered, the negatives are that a) you have to make sure it's charged and b) you can't pump tires forever with it. I've never had it run out of battery on my, but I did get the red low-battery indicator after 4 times pumping my 700 x 32 tires to about 50 psi. Compared to a CO2 inflator though (how many spare cartridges do you carry?), I think this one's a no-brainer.

It’s very small and it does work, and you need to use the hose that was supplied with when you are pumping up TPU tubes. Otherwise you will melt the TP tube because of the heat that the pump generates.

I have been using the pump for 2 seasons mountain biking, It is so good and performs flawlessly, You don't need to take CO2 or a mini pump with you on the trails. This pump will do the job. It can pump a 29" tire from zero to 25 psi at least 4 times.

Product of the year in my opinion! What a great product. So easy to use and I can carry it easily in my pocket, not even feeling it there. Operates flawlessly. Seriously, one of the best products I have ever bought on Amazon. I also have a larger air compressor made by Cycplus that has been great for years. For biking, this mini is just wonderful. Thank you Cycplus!Update: so ridiculously easy to use, so quick, quiet compared to most others. Don’t even need the models with PSI display. You’ll know when you’re fully inflated by touch. Very happy with this purchase.

This item worked great the first time fixing a deflating tire on my fiancé’s way back from the trail but when his tire went flat and he needed to pump a tube (fully charged) it did not have the power to pump it up so he walked back. Would love a replacement if possible.

This pump is not a necessity, but if you are running TPU tubes, it's either a hand pump or this. CO2 and TPU don't go well together with cold and plastic you'll get a snap crackel pop! The unit is nice being able to set your pressure and inflated to what you need. No guessing, thumb guessing, or carrying a gauge. All in one! Small, light weight and fits in a jersey pocket just fine. Definitely play with it at home to get an understanding of how it works. Hands on vs out on the road when you are already chasing daylight, lol.

This is a blessing! There’s nothing worse than getting a flat tire and struggling with a compressed air cartridge.I get about two full tire inflations from a single charge. I only wish I had purchased the slightly more expensive version with a display to set the desired pressure.
