So i bought a small electric pump off Amazon from the brand GPUTEK for £35
I was a bit sceptical about how well it would perform, a few home tests and it inflated a flat 2.4 tyre 4 times before the battery died
Anyway on today's ride a friend had a small puncture 5 miles into a 35 mile ride (he is still on tubes & not intrested in tubeless)
The pump was used every 5 miles to top the pressure back up from 10 psi to 28 psi, we recharged the pump using his powerbank for the last two uses
I was really impressed with it, saved me having to remove his rear wheel, find what had caused his slow puncture and then fit a new tube, no need for endless hand pumping in this hot weather (plus ive not used my small hand pump in over a year so need to check its still working ok) and no need for any one time use co2
I was very impressed and so was my mate, who whilst i was reinflating his tyre ordered one off Amazon on his phone whilst still refusing to go tubeless
Glad to hear that as I have a charged and thankfully so far unused one of those after using a similar one on a flat on a club ride the other week
Wouldn't be without mine now.
It's a Trek branded one, digital gauge and pressure setting. Small, lightweight, battery lasts ages, does exactly what it claims.
I think it's like those radar rear lights. Everyone scoffs and asks why you need one of those, then they get one and it's like "wow, how did we manage without?!"
So replacing a manual pump with one of these new ones also relies on a power bank to be carried about and plugged in? Seems an inordinate faff when a manual pump is so easy and reliable...the smaller size is appealing but the limited usage without something else to charge it up seems a major flaw.

Ours will/should do two road bike tyres from zero to 100+psi. That's a ride worth of flats. No power bank needed.
It's far less effort than a mini-pump.
If you think about it more like a less wasteful CO2 cartridge it makes more sense. If you carry two CO2 cartridges and an inflation head it is quite similar in mass and bulk. I would carry CO2 and a mini pump regardless so it's a step forward for the tubed bikes.
It won't bang a tubeless tyre bead back on the rim like CO2 but it will inflate quicker than a mini pump with more certainty on good end pressure.
I got one of these from Topeak for my birthday - muck like the radar light that I also got from another - another thing I wouldn't spend my own money on.
Unlike the radar - I probably still wouldn't spend my own money on.
If the radar broke I'd replace it tomorrow I've seen the light ( badumtish) If the electric pump broke I'd just revert to my manual pump.
And I still carry a manual pump.
As above I just view it as a replacement for the co2 carts I always carried along side a pump on a bracket.
I did use it a fair bit on my GGW and outer Hebrides tour - as it was majorly varied terrain I adjusted pressures a few times for extended off-road sections Vs the road. Far more convenient for that than my pump but very much a nice to have in my mind.
I like mine apart from the noise. it's offensively loud.
I’m currently touring with baggage transfer. I have track pump in with my cloths. In a minute I’ll go and see if the sealant has properly sealed a slow puncture. I pumped the tyre twice yesterday. If i was actually carrying my stuff then an electric pump would be fab. For the pressure gauge as much as anything
I was initially sceptical but I am now converted. Dead handy little device for checking/topping up pressures.

I have occasionally wondered how disturbing the noise is in adjacent Premier Inn rooms
I'm sure it not the worst thing you'll hear from an adjacent Premier Inn room.

We’ve all been there. But i thought we were talking about electric bike pumps

I would have thought it was easier to change a tube and find the puncture instead of repeated pumping. I would also teach your friend how to mend punctures so they as self sufficiant..
I was really dubious about these but a mate who runs stupid low pressures and is forever burping tyres has one and it's definitely a lot more environmentally sound than the CO2 canister he'd burn through on nearly every ride.
I'd also thought that you'd always find it flat when you need it but it's occurred that if you use it to check your tyre pressures at the start of every ride you'd be more likely to keep it charged.
I want one, but I'm super dubious about the quality/lifespan of the batteries in cheap Chinese stuff. Does anyone make one that you can replace the LiIon in when it dies? ie that takes a standard LiIon cell? that would be a winner.
Ok - it seems Zero Friction Cycling have tested a load of these a lot more thoroughly than any magazine is going to

and it even includes ease of replacing battery. and for all but the Fumpa but it notes he couldn't get a replacement seal out of the company because they were too busy, despite advertising their products as being serviceable/repairable.
Electric inflators. So the cheapest of the ones ZFC rated highly is the Muc-Off. £100rrp, can pick up for about £75 discounted. But appears to be a rebranded RockBros inflator which you can currently buy from the RockBros official store on Aliexpress for £51
7.4v 600mah pack seems to be a common thing. Only challenge may be the mini connector but I see it being an easier battery to change than the one in my Garmin.

£43 + P&P
Can't comment on performance.
There was a thread a while back about this. I bought the aliexpress one recommended in that. It is noisy but it's also brilliant. Not had to inflate a tyre on the trail yet, but even for just punching in the PSI you want on the bike you're about to ride (so that might be a specific use case for a man with too many bikes 😉 ), it's already worth the £30 or so I paid for it.
EDIT: it looks an exact copy of ^^ link posted above. Just with a different name.
No need to carry a power bank if you don't want to, it just happens that my mate had left his power bank in his bag as he uses his phone for navigation, after 5 top ups using the pump we just used the power bank for 10 mins to top the pump back up, Ive not used my manual pump in a year, I've no idea if its working ok, the electric pump will inflate four 2.4 tyres from completely flat to 30psi before running out of battery so no need for a power bank really
A slow puncture on a hot day, bike covered in dust and an oily chain (that’s another issue which I've given him advice on) id rather keep topping it up every 5 miles than deal with the faff of removing the rear wheel, finding what caused the puncture and fitting a new tube, he is more than capable of fixing a puncture, we just chose the quick and easy option, total time taken to keep pumping the tyre up over the 35 mile ride was no more than 5 mins

Coospo sent me the X1, can't compare with any others but I always take it with me and a few months later it saved a ride where I had a leaking valve used it a couple of times to get me the remaining miles back home, saved wasting Co2.
I like the look of the Cycplus ones. But there are about 4 models and I’ve no idea which is best. I like the idea of not needing a hose to attach to the valve.
So, does anyone use one of the AS2 variations from Cycplus and can recommend (or not).
I had an AS2 pro which I used daily to top up the commuter, based on the ZFC data, it seems to be the best compromise between battery life and weight, also have the handy digital gauge.
However, it died after 6 months with a pressure gauge error, Cycplus sent out a new one straight away after seeing a video of the error. I took the old one apart and it seems to be caused by sealant getting on the sensor, but no amount of cleaning could fix it so it's now sat in the spare box in bits.
I relied on it so much I bought one from my LBS before the warranty replacement arrived. The only one available there is the Muc off Pro one. The electronics looks exactly the same as the Cycplus one, I think all of them are probably made in the same factory in China.
However, there are a few improvements. The digital gauge is on the same side as the valve on the Muc off and the actuate button is on the side. This layout is much better in use.
Also, the design of the valve is much better in a way that there's a little silver cage under the seal that seems to trap sealant and it's very easy to take out to clean. It's also a much more difficult path for the sealant to get to the sensor even after the silver cage's been removed.
So although it's probably made in the same factory, it's much better designed than the Cycplus, so I kept the Muc off and sold the Cycplus.
Tuesday night: mate ripped a tyre on a descent.
Between us the group (well, me) had pumps, tubes, boots and levers.
My MucOff electric pump was brilliant. Got the tyre back up to pressure quickly and we all had a laugh in the process.
No need for a gauge as that's what thumbs are for.
Happy days.
