Anyone try one of these mini electric pumps?
Very tempting. Even if I did recently buy a big box of CO2 carts. https://www.amazon.com/ROCKBROS-Elec...d_i=B0C77398NP

I bought one from AliExpress for under $20. Works as advertised. Charges quick via USB-C. Only problem is that there's no PSI gauge, so you need to count the seconds to get a ballpark estimate. For example 60 seconds would be around 70 PSI or something similar.

I've got a similar one I use when travelling (flying) instead of taking a track pump. It works well, but is pretty noisy! Mine's a FUMPA brand and has a digital gauge.

I use one. Great alternative to Co2 especially if you use TPU or are setup tubeless. Like other have said loud and no PSI readout but the unit also get really hot, so the rubber cover should stay on the device. You can get maybe two fully inflated tires on some road tires on a full charge.

First saw one of those on a group ride this summer. It was a Fumpa. Seemed like a cool idea, especially if you're not into contributing to the environmental issues of CO2 cartridges...but it also seemed to be really loud, slow, and bulky. So I don't see it as being significantly more valuable than a good frame-mounted pump.

The smaller design of that type are able to be stored easier.

Well, the hyperactive presenter on Cycling Weekly was raving about one that does have a pressure indicator:
It is featured in the last segment of this video.

For something like a pump that I may never actually use and will easily forget about until I need it, I prefer something completely manual and reliable that requires no batteries to charge. Chances are that if I had a battery powered pump, the battery would be dead on the day I had to use it. I also ditched CO2 for a manual mini pump as I was on a ride where I got more than 2 flats and only had 2 CO2 cartridges. With the modern trend towards wider tires and much lower tire pressures, getting a tire up to 60 PSI, even with a manual mini pump, isn't that hard... even for the scrawniest of bicyclists.

Anything that stops you building bigger arms has got to be top of the list for under the christmas tree. Q-tips FTW.

Instructions say it's good for about 6 wheels. Recharge is quick though, less than 25 minutes. I got lucky because it was a clearance promo item. Most are selling $40 and up.
I still prefer carrying a mini pump though. I just picked up due to the price and for the occasional times I fly with my bike and C02 isn't permitted on planes.

I have a couple of the Fumpa Pumps and they work really well especially for travel, I'm a fan,.

Do people really have that much trouble with a good frame-mounted pump? My Lezyne pumps (and others I've used in the past) have never failed me. I don't have to remember to charge it, and it's good for as many tires as I want. Or is this more about having a cool gadget?

You will use up your CO2 carts and it will leak out faster than room air.
I have seen a few riders use those little pumps and they seem to take way more time than a regular floor pump.
If I am going to ride 60 miles of hills, the extra 1.5 cal pumping up my tires doesn't seem like a big deal. But like Jeff N said above, maybe you just want a cool gadget. Like an electric can opener or electric wine bottle opener.

But if time to repair a puncture is important, nothing's faster than a CO₂ cartridge. If you're on a group ride, the less time it takes you to fix a puncture and get rolling again, the less time and energy you have to spend chasing the group.

Forget this and CO2. Group ride or not I am not using co2 but I do carry one cartridge just in case. I always have my Lezyne mini pump with me at all times. I never run out of air and it has a retractable hose. I can get it out and it does take longer than co2, provided you manage to get it in the tire correct. I can use the Lezyne and in about 150 pumps get my tires to 80psi which is fine. I have seen co2 not work or the rider gets it off a bit and runs out the cartridge. In the bitter cold it is not a good idea either. Once I had a flat on very cold day temps in the lower 30's. Got the co2 out the cartridge got so cold in hurry it burnt my hand and I have to call for help. Never again will I go through that, and I am a trained bike mechanic who should be able to handle a flat so easy.

Every inflator has pros/cons. Tubeless likely “needs” CO2. The electric pumps crap out after 2 uses and slower than CO2. Pump is slower but can be used repeatedly.
Personally, I carry a Lezyne pump and CO2. I only use the CO2 on a group ride where everyone is waiting for me, it’s worth saving a couple minutes then. On a solo ride I take my time and use the pump.
I don’t have interest in the portable electric Fumpa type device, but may consider in the future. Certainly they have their role, for example if traveling by plane you cannot bring C02.

A friend carries a larger one, with a fairly precise digital gauge, that works great and is good for 3-4 tires. Whenever there's a flat on one of our group rides, he's everybody's hero. But I'm glad that he's carrying it, and not me....
Not sure of the make and model.

If you get a flat, inflating the tire is not the time-consuming part anyway. Whether it takes 30 seconds with an electric gadget, or 3 minutes with a pump, seems irrelevant to me.
