Has anyone tried one of these portable electric pumps?

Frankly, if I could find one of the higher-quality electric pumps with a pressure gauge, smaller size/weight, and not too expensive, I would get one, just to try.

Zero Friction Cycling has launched his approach to standardised testing of these, so it will be interesting to see the results. The initial results for the Cycplus AS2 are in.

I have (knock on wood) not suffered a puncture on the road for many years, so my 'old school' lightweight, compact hand pump remains sufficient. For extended rides on my gravel bike (set up tubeless), I can easily see the higher pressure of an electric pump coming in handy.

They wouldn't be a bad idea if they fit alongside the water bottle cage like a mini does, but I don't want to stuff it in my saddle bag. Having said that my problem with these electric pumps is the limited air supply they offer, which is the same problem I have with CO2, but CO2 has more cons, but they are faster than the electric ones.

For me, I'll stick with manual hand pumps, cheaper, far more reliable, lighter in weight, convenient to carry, free to use. The only brand I like is the Lezyne Road Drive series; but with any pump the smaller it is the more difficult it is to pump air especially as the PSI increases. Knowing that my regular road bikes I have the middle size Road Drive, but on my touring bike I carry the larger one which is about 11 inches long, so I have it mounted to my water bottle cage that is mounted to my fork. The long version does work very well, if someone wanted a near frame size pump without the weight on a road bike because they want an easier pump to put air into a tire with that's the one to get. That long one looks good on my bike because it is small in diameter, it's shiny black, the bike is a medium dark blue, with black components, bolts, and water bottle cages, so the pump just blends in with the bike.

I have not. That sounds really convenient. I just carry a stick pump with me in my backpack in case I get a flat.

It's a workout to get up to usable PSI.

Yup, I tried one last week. My bike buddy had one, which we used on my tubeless.
Would I buy one? Probably not. I didn't see any advantages over my small manual pump, which I carry

I avoided lowering my tire pressure for descents because I dreaded pumping them back up for the climbs. While my friends did it constantly, they were on skinnier tires that were easy to fill with a hand pump. My fatbike tires take 70–100 strokes each, and I just wasn't interested in that workout.

​So, I definitely see the application for these mini pumps for my needs.

That said, in real life, I’ll probably stick with my hand pump. When I’m going up and down on a daily basis, I don’t see enough of an advantage in the constant pressure changes.

Now, I just wear better-cushioned gloves and complain less about the bumpy ride downhill!

After several years in the marketplace, and over 15 brands now, there is still not an affordable one - (under $40 US) and the one or two under $20 I would not trust. They will get better and come down in price, but for now, Co2 on the road and stand pump at home and in the car does fine.

Its convenient for road bike tires because itll easily let you get to your preferred PSI exactly so you can maximize rolling resistance you compute from online Tire Pressure calculators, it’s a world of difference and you can literally feel the Watt savings just by inflating your tire to the actual recommended PSI for your body type and Riding

UPDATE from my 3/26 post.

I hadn't had a flat for about a year before writing that post, my arthritis in my left hand/thumb has gotten worse over that year. About a month ago I had a flat, and was trying to pump my tire with a Lezyne Road Drive medium size pump and my hand hurt like hell trying to do that, I did manage to get it to about 70 psi but not without stopping several times.

Long story short, I surrendered that day, and bought a CYCPLUS AS2 PRO, this one seems to have the best inflation numbers of the others for its size. I store it in my saddle bag. I also continue to carry the pump just in case something weird happens and I need to more inflation than the battery will supply. I also transfer it to my touring bike when I go bike camping, even though that bike has a Lezyne Road Drive large pump it still hurts my hand.

I looked at all the brands out there and the AS2 PRO seem to be the best and the highest reviewed. I got on CoPilot to double check my research and it too concluded the same thing I did. There is a situation, my criteria was a pump that could do 700x25 up to 700x40, I don't use any other tire sizes, so if I had a 26x2.00, or a fat tire bike for example I might have gotten a different answer other than the AS2 PRO.

I haven't used the pump yet due to not having a flat, so I can't respond to how well it works but all the reviews and videos I saw showed it working very well, if someone wants, I can test it by deflating a tire, but I don't see the reason for doing that but I will for giggles.
