HOTOMini Bike Tire Pump, 25s Fast Inflate Bicycle Pump with Guage, 150PSI Portable Electric Bike Air Pump with Presta and Schrader Valve for Road Bike, Motorcycle, Mountain Bike, Car, Sports Ball

This HOTO rechargeable mini air compressor/tire pump is a game changer! I use it on gravel bike and mtb tires. It takes very little time to go from zero to 40+ psi and it can be used numerous times before a charge is required. It pumps faster, more often and can quickly handle a high psi road bike tire on a single charge because it's slightly bigger and stronger than the competition. I've used it 4 times on one ride for a guy with a dry tubeless tire. It still had over 75% of its battery life left. It sat in my garage, unused, for a month and still maintained a full charge. The cheaper, smaller pumps I've seen require a charge before almost every ride. Not this one! It charges fairly fast and it can easily be stored in a jersey pocket or in most bike bags. It's not the smallest pump, but it's still very portable without being a burden. It's a massive time saver and it eliminates the need for CO² cartridge waste. After adding tubeless tires, investing in this pump was my best upgrade. It quickly pays for itself in no time by saving you lots of time, sweat and money.

Mighty little guy. What I love most about it is that it is portable enough to fit in my bike pouch. The build quality is solid, sleek, functional and smart. Memory feature is a plus. Have not fully use yet to know about battery life.

I do like the pump. I find cartridges difficult to use and pumps don't get the tire up to a decent pressure without a lot of work. The pump screws on to the stem in a way that all the air gets into the tire, and then unscrews in a way that doesn't let almost any air out. It has enough charge to fill multiple tires to 90 psi.Couple of caveats:The LED is very dim. It can't be read outside in the day light. This means that if you haven't previously set the target PSI indoors, you won't be able to set it on the road. If it was correctly set beforehand, though, it's ok that you can't read the pressure as you fill the tire as it automatically turns off when it reaches the target pressure.The other thing is that it doesn't always start up when I click the "on" button. I've always eventually been able to get it to start, but this is a bit disconcerting when you're out on the road with a flat.Finally, I did have one instance where, after filling the tire, and unscrewing the pump, it took out the stem's core! (The thing in the middle of the stem which allows air in and keeps it in!) By hand I couldn't get the core back in well enough to prevent it from getting unscrewed when I unscrewed the pump - eventually I filled the tire by just pressing the pump hard onto the stem without screwing it on. No fun, but that only happened once, probably with a core that was loose to begin with.

Why did you pick this product vs others?:What a game changer no more Co2 cartridges. I ride tubeless and this has been a life saver both on gravel tires 50psi and road 100 psi

Small and convenient to carry on the bike.

This is a major step up from carrying a hand pump or Co2 charged bike pumps. It's relatively compact and fits in most of my bike bags really well. I've had no problems pumping up normal size bike tires or my 4.5 inch e-moto tires. The battery feels like it lasts forever. Really cool do it all compact pump.

Small enough for a trunk bag or large seat bag. Big enough so that heat dissipates and you can hold it in your hand. Battery holds the charge and can fill large tires multiple times. Permanently attached hose ensures you can connect the pump even when spokes are close to the valve.

The media could not be loaded. I bought this air pump as I was frankly tired of paying for filling my tires (atleast $1 every time) and thought that It would also be helpful in filling up soccer and basket balls.The pump is as described literally pocket sized and works great. Its able to fill one of my car tires in under a minute which honestly is great.I also like the auto shut off feature in that I dont have to worry about overfilling it.The only thing that is a deal breaker for me is that its just too loud. I live in a rather quiet neighborhood and I'm sure my neighbors won't appreciate the random loud noises going on for a few minutes.
