The SKS EMP is a neat electric mini pump that fits Schrader, Presta and Dunlop valves, and offers three typical road bike tyre inflations per charge.





Like most electric mini pumps, the SKS EMP is really easy to use. You turn it on, input your target tyre pressure (in either PSI or bar), hit the button that starts the pumping process, and then attach it to the valve. It stops automatically when it hits your target pressure – and that’s about yer lot.

The valve head is reversible, as you’ll have seen on a million other pumps out there over the years, and fits Schrader, Presta, and Dunlop valves (you’d need to use an SKS Clik Tec Adapter for a Schwalbe Clik Valve). You unscrew the tip and flip over a little plastic widget in there to swap between valve types.

The valve head simply pushes onto the valve and works securely that way, although I generally preferred using the supplied extension hose because the screw-on connection feels more reassuring. It operates like a traditional pump hose, screwing onto the valve. The extension is also suitable for TPU tubes with plastic valve stems (the heat generated by a compact electric pump can sometimes damage or even destroy them if you don’t use an extension hose).

SKS reckons you get three 700 x 28mm tyre inflations per charge and this claim holds up. I got a 700 x 28mm tyre up to 72.5PSI – the maximum limit for the TSS/hookless rims I’m using – three times, with a little bit of charge left over. Each inflation of a tyre that size took about a minute, so you can stretch your back out, watch the clouds go by or whatever, until it has done its thing.
What about a larger tyre? I got two 650 x 42mm gravel options up to 40PSI in 1:30mins each, although the EMP ran out of juice at about halfway the third time around.
The operating pressure is up to 120PSI (8.3 bar), which safely covers most typical scenarios (other than track). I actually had some 700 x 23mm tyres from ye olden dayes kicking around in the back of the shed, and the EMP got them up to 120PSI without too much strain.

How accurate is the pressure indicator? I used the EMP to pump up a bunch of tyres to various pressures, then checked them against the readings from a trusty Topeak SmartGauge D2 pressure gauge, and the readings always closely matched, so we have no worries there.
SKS says that you can recharge the 500 mAh 7.4V lithium-ion battery from empty (using the USB Type-C cable provided) in about 25 minutes, although I actually found it quicker than that. SKS advises you to recharge the pump fully at least once a month.
Weight? SKS says 151g. Ours did indeed hit the scales at 151g, but that was without the silicone sleeve or the pump head. Add those (SKS suggests you always use the silicone cover because the pump can get hot in use) and you’re looking at about 182g. The optional extension adds 13g (although it’s actually a net increase of 8g, if you want to get fussy, because it allows you to leave the 5g pump head at home).
We’ve reviewed lighter electric bike pumps here on road.cc. The Truflo Electron Compact Electric Pump was 120g, for example, and the Magicshine Airro was 145g.
Personally, I wouldn’t get too excited about a few grams either way. Essentially, it’s lightweight and easily small enough (83 × 33 × 52mm – smaller than some, a little larger than others) to fit into a jersey pocket with plenty of space to spare, and you get a little storage bag to stop it getting scratched by your keys, or whatever else you’ve got squirrelled away in there.

Is it noisy? I measured it at about 80 decibels from a distance of a metre. That’s not as loud as a hairdryer, say. You’re not going to miss it but, on the other hand, I wouldn’t say it’s offensively loud either.
At an RRP of €79.99 (you can find it for less… and more) the SKS EMP is more expensive than the Truflo Electron Compact Electric Pump (£49.99) that we reviewed earlier in the year, and a similar price to the Magicshine Airro Digital Electric Mini Pump (currently £70) and the Muc-Off AirMach Electric Mini Inflator (now £75).
On the other hand, the Topeak E-Booster Digital Mini is more expensive at £109.99 and Silca’s Elettrico Micro Inflator is £129.99.
In other words, the SKS EMP isn’t especially cheap, but it’s not particularly expensive when compared with options from other established cycling brands.
Overall
The SKS EMP doesn’t reinvent the electric mini pump, but it gets the basics right. Inflation is accurate, battery life matches the manufacturer’s claims, and the supplied extension hose is a genuinely useful inclusion, particularly if you use TPU tubes. It’s not the cheapest or the most powerful option available, but it’s a dependable performer from a company with a long history of making good pumps.
Test Report
What does the manufacturer say about this product?:
SKS says, “The EMP electric air pump inflates your bike tyres quickly and effortlessly up to 8.3 bar (120 PSI). At only 151 grams, the rechargeable mini pump feels effortlessly light – perfect for your ride-outs. The reversible pump head can be easily switched between Schrader (AV), Presta (SV) and Dunlop (DV) valves. With the included extension hose, the pump can be screwed comfortably onto the valve. The extension is particularly suitable for TPU tubes with plastic valve stems.
“Here’s how it works: Select the desired tyre pressure – the integrated memory function automatically saves the last setting used. Press start and place the bike pump onto the valve. The digital display shows the current pressure in either bar or PSI. Once the target pressure is reached, the pump stops automatically – so you are back on the road with fully inflated tyres in no time. Once fully charged, the battery provides enough power for up to three tyre inflations, ensuring you won’t run out of air on the road. Using the included USB cable, the electric mini pump can be fully recharged in approx. 25 minutes.

The SKS EMP does exactly what it’s supposed to do; the manufacturer’s claims are accurate. The fact that there are plenty of cheaper rivals out there these days could drag the overall score down a point, but it’s a very good product overall and that warrants an 8.
