Does anyone have real world experience of mini E pumps such as Fumpa pump, muc off air Mach etc? They seem to be getting a lot heavy marketing as the solution to carrying CO2 and mini pumps but I haven’t met anyone who uses one yet.
Do they do the job? Get to pressure, easy to carry etc?
They seem like a good idea in principle but the flood of targeted marketing I’ve had on social media about them makes me a bit suspicious.
The Cy plus AS2 Pro seems to get decent reviews.
Have a friend with a Fumpa and it seems ok. It's nice and small for fitting in a jersey pocket. Seems to have a quite limited number of times it will pump your tire up on full charge so if you end up with a slow puncture and need to pump a few times to get home or if you screw up replacing your tube and end up punctured again you will struggle otherwise it's ok. He likes it, I still prefer a small hand pump for reliability
I’ve got a Cycplus AS2 Pro, I got it early November
It gets used on my mtb with 29 x 2.5 tyres probably weekly to keep them up to pressure.
I love it. Never needed to used it from flat as yet out on the trail, but I have used it at home reseating tyres . I’ve used it on the trail to pump a lads tyres up that were a bit flat he was well impressed
Best bit is you just set your pressure you want put it on the valve and it’s done, I wouldn’t buy one that does allow you to set pressure
They do get very hot when using them.
Will have to see how long it lasts, but it’s 100% reliable so far and weighs less than a normal pump
When I bought it, I put it in the basket. Overnight I got a 10% off code. Ended up costing me about £75
I’ve got a cheap AliExpress one. Basic, no gauge. I’ve used it to top off tyres and fill my tubeless fire extinguisher based inflator.
Its pretty good, small enough to fit in a frame bag or seat pack in the small resealable bag it came in.
On the MTB punctures are so rare my frame mounted pump Often doesn’t work or is full of muck the time I actually need to use it, that said for a big ride I’d take a (tested) normal pump.
Thanks for the replies.
I think I will give one a try. Agree that trail punctures are a rarity so it might be easier carrying one of these rather than a pump.
I actually mistakenly ordered the Cycplus AS2 instead of the Cycplus AS2 Pro - and it seems only the Pro version has the guage.
Much like Funky Dunc I like the idea of quckly popping it on before leaving the door to set the pressure with the guage like the car pumps.
How much air do they throw in? Would it work to inflate a tubeless tyre if the beat was cracked?
Never tried one and with my limited exposure of them, I'd suggest they'd be great for half of the times I'd use a pump...so I'd be sticking with my pump and co2 cartridges solution.
@FunkyDunc, if your setup is tubeless, then add a wee bit more sealant in and you shouldn't need to keep topping up on a weekly basis. Apologies if you know that already, but if so, something is leaking if you need to top up weekly.

Probably won’t seat a tyre but mine will charge my inflator without the noise of my compressor, also dead handy for topping up tyres when a bike is hung on the wall.
Sure they have their limitations but, they recharge and unlike CO2 won’t cause the sealant to go off.
I’ve had an as2 pro for a while.
I haven’t needed to do a full inflate out in the world but being able to top up a squishy tubeless tyre to the correct pressure has been useful a few times. I’ve always liked the compactness of CO2 but never managed to reliably use a canister more than once - this solves that for me.
In terms of flow rate I’d say somewhere between a frame pump and a track pump. You’d maybe get away seating a tubeless tyre with one but it wouldn’t rely on it for that job.
Just ordered an AS2 Pro Max, will head back with a review when it arrives
The rock bros inflator was surprising. These rims have been easy to seat tyres on with just a track pump though so make if that what you will

They did catch my eye, but ended up going with the AS2 for the hose
The rock bros comes with a hose, Schrader and football adaptor
Clubmate had one on a ride last week, apparently the battery didn't like the sub zero temperatures so only inflated the tyre once. No idea how long it has been since it was last charged though.
I was pretty impressed still. But I'd probably still carry it and a mini pump for road rides. Although I suppose a power bank would solve that issue equally well.
For anyone interested, Cycplus AS2 Pro Max is £101 at the moment from Amazon.

I've not used mine yet, but it arrived a couple of weeks ago.
It's huge for what it is and to me seems to negate the point of having a mini electric pump. Yeah it'll be easier than using a normal pump and last longer than C02. But you have to have a backpack or hip pack to carry it and to add to that, it's not waterproof so you have to put it in the crappy supplied ziplock sandwich bag. Buying again, I'd try and find something pocketable - in fact I think this will go on eBay
I met a chap who was stranded as his mini electric pump had run out of power.
A complex solution in search of a problem and a triumph of marketing over utility

I did wonder why you went for that one, I assumed you wanted to pump up car motorbike or car tyres !?!
The AS2 Pro is about half the size of the one you (incorrectly?) ordered.

Not the pumps fault that he didnt charge it.
I think hand pumps are overly complex. I just set the pressure i want, put it on the valve and sit back for 5 seconds whilst it pumps up, not sure why that is more complex that a hand pump that requires effort and guessing as to what pressure you are at.
Charge the headlight ,Garmin, power meter, rear radar , gears , ebike , emergency powerpack and now the pump 🙂
I think the concept sounds nice but I’m afraid happiness is an endless decent mini-pump when your on a nice long bike ride.

It failed out on tbe trails. How was he supposed to charge it miles from anywhere? He had used up its capacity in a day. It was a tiny one and he had high volume tyres
Ah that’s why you carry an emergency power pack, so you can charge your pump en ride 🙂
(Then you have to carry another/bigger battery pack for real emergencies.)
It’s just another variation on carrying just c02 cylinders without a pump with the inherent comedy issues that has.
I just bought one of these from AliExpress. Cyclami A2s cost 26 quid. I was not counting on using it as my sole emergency pump, but I thought it might be handy to quickly top up my tyres when heading out of the door, and to take on local rides where I have the backup of asking MrsJ to come pick me up in the car if it all goes wrong.
Observations -
- the battery is quick to charge but its capacity must be low as I don't see it filling more than 2 tyres at most.
- it's incredibly noisy and it gets quite hot
- it takes a long time to inflate the tyre
- it's hard to keep a good seal to the valve without using the screw on hose, whcih somewhat negates the value for a quick top-up
I didn't pay much for it. If I'd paid full whack it would be going back
Update now I've tried them all, spoiler -there's very little to choose between them unless you need the extra capacity
So they cost a lot more than a mini pump, need charging up, can do about 2 tyres before they run out and people are recommending that your carry a powerbank as well to charge it up if you need it more than that? And no one knows how long they’ll last before they die as they all seem to be generic Chinese products? Also I’m guessing they’re not very recyclable.
I’ll stick with my trust Lezyne mini pump and track pump.
