If you like the sound of a lightweight, pocket-sized electric pump that can automatically inflate an inner tube up to 120 psi, you need to check out the EausAir project on Kickstarter very quickly because it ends soon.
There are lots of little electric pumps out there these days, but the creators of EausAir Mini pump say this is “the world’s lightest and most portable 120psi visual inflator”.
It weighs a claimed 178g and measures 51.8mm x 35.9mm x 75.8mm, so you can easily carry it in a jersey pocket. For comparison, the Topeak Pocket Rocket – the best manual mini pump out there – is 109g, so we’re not talking about a vast difference.
> Best cycling mini pumps 2023 — tiny tools to get your tyres topped up
The Bosch EasyPump (£69) that we reviewed last year was quite a bit more at 420g, and much bulkier too. For even more context (hey, why not while we’ve got the scales out?) an Apple iPhone 13 comes in at 173g, so very similar.
The EausAir Mini features an aluminium alloy body, works on Schrader, Presta and Dunlop valves, and has a digital display. Many inflators at this size and price lack a screen, leaving you to guess your tyre pressure or rely on a quick press of your thumb. Inflation stops automatically when your inner tube hits the pressure you’ve set.
The team behind EausAir reckons it has an airflow of 20L per minute and will inflate a 700 x 23 tyre – if anyone is still running 23s – to 100psi in about 28 seconds. The sensor accuracy is claimed to be within +/-1 psi. The built-in 600mAh battery charges in 39mins via USB-C and there’s a battery-level indicator on the display.
You need to pledge at least $89 (around £73) to be in line to receive a EausAir Mini pump, and you need to do it before 12:57pm (UK time) on Monday, 30th October. As we always point out with crowdfunding, it’s not the same as buying through a retailer – rewards aren’t guaranteed. Delivery is planned for January 2024.
What do you reckon? Is it time to ditch the annoying mini pump and/or avoid the faff of CO2 cartridges and go electric? Or does the potential for a flat battery put you off? We’re interested in hearing your thoughts.

What I did not see here is how many times you can inflate a standard 28mm road tyre to x psi. If it is only once or twice or even threice, then the mini pump is safe.

I’m calling bullshit on that.
Other similar products get ~2 full inflations of a road tyre (700×28). https://escapecollective.com/mini-electric-tyre-inflators-nanofumpa-vs-cycplus-cube-review/
Officially, the Nano Fumpa only claims to be good for a single inflation: https://www.fumpapumps.co.uk/pages/nanofumpa-manual
Whilst the Cycplus Cube says <=4, depending on width: https://www.cycplus.com/products/tiny-pump-cube
It might have a slightly larger battery – the Kickstarter page says 600mAh for the EausAir Mini compared to 300mAh for the Cycplus Cube. I can’t find a spec for the Nano Fumpa but based on size alone I would have to guess similar. But even allowing for double or even triple the battery capacity, there is no way it is pumping up >20 tyres on a single charge.
Exactly. Add some cold temp
Exactly. Add some cold temp to reduce the battery capacity by 20/30% and it looks even more pants..
I consulted the one on
I consulted the one on kickstarter and they can fill 4 700*25C tires. The 20 mentioned in the news is that they describe that 20 can be replenished under 80%-100% air pressure. It’s probably that you have misunderstood this. If Cycplus (300mAh) claims 4, then EausAir (600mAh) claims 4, which is reliable. I bought Cycplus on Amazon, but didn’t really test it. But it’s no problem to use it twice now.
It’s also good exercise. I
It’s also good exercise. I only carry pumps on all my rides, never CO2 as I don’t see the point unless racing.
It takes me maybe 90 seconds to remove my pump, inflate the tyre, and replace the pump in the holder. Punctures are rare (especially on my one bike set up tubeless) and CO2 takes at least 30 seconds, so I’m losing maybe a minute a couple of times a year.
It feels like a MINI air pump
It feels like a MINI air pump is really easy to use. It is about the same size as AirPods Pro and is very convenient to carry. I bought a similar product on Amazon and it works great so far. It doesn’t require any complicated operations. You simply align the valve and press the switch to fully inflate the tire.
Can you test one at around
Can you test one at around freezing point please.
I’m sure an alloy box with a battery will love sitting in a jersey poket around freezing point and then tasked with inflating one, maybe two tyres.
What does that do to the time taken, and how may goes do you get at getting a 28 to 70psi?

And honestly, if it’s on kickstarted all stats are probably best case lab conditions and will be available in 2026 after they’re available in stores for a lower price.

Great news. They’re interesting, but my concern is low temp conditions.
if you can include some cold temp research, that’s would be fantastic.

Will be interested to read
Will be interested to read when it’s ready, the flaw with most of these is the lack of ability to set a PSI and it stop once you’re at the right pressure. A very useful feature if running latex / tubeless and wanting to top off quickly before a ride without getting out a proper pump and obviously making sure you’re at the right pressure after fixing a flat on the road.

I bought a similar one on Amazon and I think it works great. But the configuration of the one in the news seems to be much better than mine, so I bought it early. But I still like this mini air pump, it’s so convenient.

This configuration is a bit lower than the one mentioned in the news, I bought one, the price is the same, but the cycplus can only hit 100PSI, the battery capacity is only 300mAh, while the Heatou in the news I looked at it, it shows that it has 600mAh, and is able to hit 120PSI. i have a feeling that it’s just an upgraded version of the cycplus.

Although of course, the average person here on a typical Dutch bike is not really likely to buy this thing. Nobody caries a pump here either afterall.

Are punctures such a frequent
Are punctures such a frequent problem that its really worth investing in an expensive electrical pump of variable capability ?
I last had a puncture riding the Way of the Roses in 2020. Since then Ive done LEJOG and Munich/Rome without punctures – maybe I was just lucky.
Also one advantage of moving to wider tyres is that they are easier to manually inflate with a hand pump.
I bought a similar model on
I bought a similar model on Amazon. The configuration is lower than this, but it is enough. I bought it in July. In September, my friend and I were riding in the mountains, and sharp branches directly punctured the tires. It’s really terrible. Bad luck. Fortunately, the MINI air pump came in handy the first time I brought it on. Otherwise, encountering a flat tire outdoors would be a real headache.
Don’t know if the *puncture*
Don’t know if the *puncture* is the problem, or where the tyre went flat *is*.
I ride through a couple of areas of Glasgow that are densely populated with pedestrian, have narrow pavements and a reasonably high Ned content.
A puncture in that area, I’d try to shove a CO2 cannister in there first to get me somewhere a touch safer to deal with the tube replacement.
In more suburban areas, I’d probably use CO2 or an electric pump as I just want to to get rolling again ..
I don’t feel particularly safe dealing with punctures in urban areas; I’m a vulnerable solo target with easily stolen expensive kit, diverted attention and just want to get away quicky.
It’s not changing the tube that takes time … its the finding the cause of the puncture in the first place so it doesn’t then do the same to the next tube.
I’m more likely to use the mini-pump out in the sticks where I’m not as likely to be in someone’s way (or at potential risk from Neds)
A CO2 will inflate a road tyre in a few seconds (or less), an electric pump in around a minute (to 100psi according to the leaflet that came with mine), and a mini-pump takes significantly longer.
For me … the technology is about personal safety as much as ease.

I’ve heard these small electric pumps get too hot to hold when in use. I’d be curious to know if that is a factor with this design as well.

I’ve had a mini fumpa since 2019. The manufacturer warns against using the new tubolito style tubes without an adaptor as the pump head might melt the plastic valve but the main body barely gets any hotter and is certainly nowhere near too hot to hold.

What I’d like to see is an electric pump in a mini pump design based around a 1500mAh 18650 cell.

In fact, I think the battery capacity is not a big problem, originally cycling needs to be light, but if such a large capacity battery instead of bulky and not conducive to carry. The purpose of this kind of MINI air pump is to deal with the unexpected situation of flat tire, emergency only. I bought one from Amazon that is only 300mAh, but it’s enough for emergencies, I used it twice and felt it was just enough to be good.

It would be an interesting exercise to list all of the cycling gubbins things with a marker: “not needed by anyone” vs “not needed by most” vs “needed by a few” vs “universally beneficial”. Or summick.
Besides these silly-pumps, what else is universally not-needed by cyclists? I’ll add: the handlebar data-collection gizmo (all types).

Seems everybody forgets mini
Seems everybody forgets mini pumps, cartridges and now these electric pump thingies aren’t the only options.
I don’t use cartridges (I hate throwaway stuff, and I wouldn’t feel secure no matter how many I would bring with me on a ride anyway).
Mini pumps are only good at being mini. They sucks at actually pumping up tires. I’m not an impatient guy, but I always feel like an idiot when I’m doing over one hundred 10cm strokes only to find that it still isn’t enough.
These electric pumps are expensie, noisy, and – like with cartridges – I would not feel secure because of its limited capacity. And I don’t want another thing to charge.
So what do I use?
Simple: a slightly larger pump. I have the Hybrid Bike Hand Pump from Decathlon.
It’s super cheap but solid quality, and the bigger size and the hose makes all the difference in the actual pumping.
It fits in my frame bag easily, and when I don’t carry that bag it’s strapped on the down tube with two simple straps.
No charging, no endless pumping, no need to keep buying cartridges.
K.I.S.S.
The manual pump is really
The manual pump is really troublesome to use and cumbersome to operate, which wastes time and energy. I bought a MINI air pump similar to this one on Amazon, but that one only has 300mAh, and this one seems to have higher configuration than the one on Amazon. I’m a little excited, but I have already bought one and the experience is quite good. It is not as bad as you said. This is a fact. I’ve seen the manual model from Dicatron in the supermarket, but I didn’t like it very much.
Troublesome…?
Troublesome…?
No charging, no keeping an eye on the charge level, no worries about wether or not you have enough charge left if you get more flats, no questionable performance in colder temperatures…
You screw the hose on to the valve, and pump up the tire. That’s it. Takes about a minute, two minutes tops.
If you call that cumbersome than, well, yeah… I’d advise to envite your bike shop mechanic with you on every ride.
At least I feel like most of
At least I feel like most of the time when I ride I don’t want to carry bulky stuff, it puts me off really, maybe everyone doesn’t think or feel the same way. I still like the convenience of technology. Similar to how a lot of people like to carry a bulky DSLR camera when they go out on a trip, but I feel like using my phone to take pictures is enough for the main scenario functions as well.
I like the convenience of
I like the convenience of technology too, it’s just that on the one hand I don’t think these electric pumps are actually very convenient yet (for the reasons I stated), and on the other the simple pump I have is way more convenient then most (smaller) mini pumps. It’s a little bigger, but it’s very light and strapped to my bike or in my frame bag, so any never actually experience its ‘bulkiness’.

As for whether you buy it or not, no one can force you. Everyone has the right to choose.

Well, some don’t think that the effect of advert, fashion, peer pressure and so forth are “forcing” because the little homunculus said to live inside us all is somehow free of all such influences, and full of objective rationality, to enable “correct” chocies to be made. But that’s just made-up-stuff. Adverts, fashion and peer pressure all work to cause we consumers to consume stuff that we have no need for in any practical sense. Why do you think such techniques exist?
As to the right to choose …. even if there was a rational homunculus able to do so, if you ain’t got the dosh, you can’t “choose” all sorts of things, such as a bicycle costing thousands and thousands or even food, in millions of cases within Blighty alone.
And then there’s the things we should be able to choose but can’t because some git has removed them. A swim in the sea or a river without getting torpedoed by a turd, for example, is very difficult for many unless they travel a hundred miles or more to somewhere free of badly run efluent facilities. Many will try to drive to such a place but this choice will be denied by a loon in a car crashing into them.
And so forth.

Um, how should I put it, I think everyone has their own understanding. I’m not averse to new tech products, and I even love these gadgets.
As for what you said about consumer advertising, isn’t Apple, the best mobile phone in the world, also full of advertisements? This does not affect people’s love for it and the fact that Apple’s advertising contains fraudulent and false propaganda, etc.
Also, if you think it does not have such technology and is not practical, then I can tell you that it is really too practical for me. I bought a similar model on Amazon in July this year, although it It’s not as good as the Eausair, but I believe the customer reviews on Amazon have proven that it does work. I’m using it myself and it really helps me.
So, I think the discussion about consumerism and advertising can end here. Everyone’s views are based on their own social practice and cognition, so I respect everyone’s views. This does not mean that you are wrong, because everyone’s exit is different.
