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

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.

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.

Works very good but not as totally confident as I thought. But I would buy it again

small enough to carry with me on a ride

I gave it 1 star review because it barely filled up a tire on my road bike. Another time I tried to use it, it did not start at all despite having charge. This product is unreliable. A waste of money.

Seems to be high quality. Yes, it's noisy, but that doesn't matter to me. It gets a little warm but not excessively hot. Inflates faster than I would expect. I have been charging it after each use, I haven't used the battery completely yet.There is no gauge or display, but I favor that for simplicity and durability.

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.

Great compact pump. Lightweight and filled a 700C x 35 tire easily.
