KEPEAK Mini Bike Pump, Bicycle Pump with Digital Pressure Gauge, Portable Bike Air Pump Tire Inflator with Presta and Schrader Valve for Road, Mountain, City, E-Bike and Ball

The new electric mini—actually, more like micro—bike pumps are a fantastic invention. Most of them are likely manufactured by only a few OEMs in China, similar to many other products. That doesn’t bother me; I focused on finding features, honest reviews, and a price that was attractive without being excessively cheap.This particular pump ticks all the boxes. Its greatest appeal is the two ways to connect the device: by hose or directly to the valve. Most importantly, it comes with separate connectors for Presta and Schrader valves—no pesky Schrader-to-Presta adapters that many other models offer. That’s a thoughtful feature.Like all of these pumps, it does get hot and can be noisy, but it works very well and quickly. I tested it on a fully deflated tubeless tire that was still locked onto the rim. It took just 25 seconds to inflate the 700x30c tire to 30 pounds. Fortunately, I haven't needed to use it during a ride, but I did use it to top off the air in both the front and rear tires. It took only 7 seconds to raise the PSI by 9 pounds—I'm not exaggerating; it’s very impressive.I can't comment yet on its longevity or whether there will be any battery depletion issues. I've kept it in my bike bag for the past two weeks, (eight rides), and it was fully charged when I took it out to top off the tires.If I need to pump up a tubeless tire that has lost its seal during a ride, that could be a deal breaker. However, as said previously, tubeless tires are designed to stay locked onto tubeless wheels even when riding on them while flatOverall, it's a marvelous invention.

I’ve been using this mini electric bike pump for over a week now, and I’m genuinely impressed. Despite its tiny size, this thing packs a punch. It inflated my road bike tire from 0 to 50 PSI in under a minute, just as advertised. It’s accurate too—the digital gauge displays real-time pressure, and the auto shut-off feature is super handy so I don’t have to worry about over-inflating.The pump is incredibly lightweight and portable—small enough to fit in my jersey pocket or saddlebag without adding bulk. I also love that it remembers my last pressure setting, which saves time when I’m topping off tires before a ride.I’ve used it on my mountain bike and even to inflate a soccer ball using the included needle. The noise is noticeable, but nothing too annoying, and the air hose does get hot after use, but that’s to be expected with such a fast motor.

I just received the pump several days ago and my first question which was satisfactorily answered was battery life. I was able to pump and deflate a 32 mm tubeless tire to 45 psi 5X. The battery was not depleted so I may have been able to get 1 to 2 additional cycles but this was more than adequate. I also carry a small power bank with me for lights and computer charges as an emergency backup. The pressure gauge was a plus and seemed to be reasonably accurate. I was able to validate it with both a Topeak digital gauge and floor pump gauge so I suspect it is within an allowable 2psi. One of the big pluses over CO2 for tubeless roadside repairs is the ability to more accurately and slowly inflate a plugged tire to avoid blowing through the plug with a sudden CO2 blast. It is also reasonably compact and worked well without the added extension hose. My biggest concern is durability. There is a lot of plastic here and I have concerns about how this will hold up over several years. For now, I still have room in my seat bag to carry CO2 which I will continue to do as a backup. My frame pump however has been ditched.

Excellent little bike pump. Pumped up all 4 bike tires without any issues BUT it did get very hot towards the end.Still had plenty of battery capacity remaining after doing that. Both types of tire valves worked fine.A little complicated to work out how to use it, but got there eventually after careful reading.We ordered another one at the same time but it weighed almost double so we returned it without testing as we needed a lightweight one.I tried it to pump up car spare to 60 but it only made it to 40 before stopping due to overheating, I didn't deduct anything from my review since it isn't designed for that, I just ran it as a test.

Product works amazingly easy and fills tires quickly.

garbage.used 2 times. I literally pumped 2 tires from 20psi to 24. now it is dead. Gets extremely hot on charger (like burn your hand hot) the charging LED never illuminated, and it will not turn on or function. I have contacted KEPEAK and I'm awaiting their response and resolution.UPDATE:A new unit is on the way from the manufacturer. Will update with info on the replacement
