Electric bike pumps reviewed: The fastest, lightest, and loudest portable inflators [Updated]

Asmax T30

The Asmax T30 is the most affordable among the smaller, trail-portable pumps tested above. It’s also one of the fastest to inflate a tire from zero to 20psi, and blows almost six inflations on a single charge. Oh, and it’s the lightest of the crop.

Asmax gives you an extension and a couple of adapters to fit Presta, Schrader, and Dunlop valves. Initially, I couldn’t understand why the hose didn’t fit my Presta valve. Turns out it’s set up for Dunlop, which I know nothing about because I’m not a thousand years old. To use the hose on your Presta, you need to screw the red Presta connector onto the end of the hose.

Where the Asmax falls short is in the sound department. It’s the loudest pump that I measured at 90dB. Based on a quick search, this is on par with a lawnmower, blender, or a person shouting in your ear. All of these pumps sound more like a hairdryer to me, and I wouldn’t call any of them “quiet” by any means. In fact, anything above 85dB can damage hearing over time, so you may want to plug your ears while you inflate.

Like the State inflator, the Asmax T30 has an LED to help you find the valve in dark conditions. The Asmax’s digital display renders smoothly, though it can be hard to read in bright conditions.

Fanttik X9

The Fanttik X9 is by far the largest pump in this test. I don’t recommend this model for on-trail use unless you’re a strong rider and don’t mind hauling extra weight (it weighs almost a pound!). Still, I had to include the Fanttik X9 in this test because it’s the most-purchased pump among Singletracks readers. I suspect this is because of the price (you can often find it for less than $40) and its promise of long battery life.

By the twelfth inflation during my test, I was hoping — no, praying — that the damn Fanttik battery would run out. Of course, if I were on the trail, I would be rooting in the other direction. The Fanttik ultimately inflated 15 tires from zero to 20psi, double what the next-best pump could do on a single charge.

The Fanttik X9 comes with a rather convoluted hose that screws onto a Presta or Schrader valve. All the others in this test simply press onto the valve, making them faster to attach.

Surprisingly, the Fanttik proved to be the slowest pump in the test, but also the quietest. Though it’s a quality pump, I recommend spending a few bucks more and getting a Fanttik X10, which weighs about half as much and takes up much less space in your pack.

Fanttik X10 Ace Mini

Unlike the X9 above, the Fanttik X10 Ace Mini is portable enough to take on the bike. The USB-C rechargeable battery delivered eight 0-20psi inflations in our 29×2.4″ tire test, placing it in the middle of the pack. It might’ve eked out one more inflation if not for a strange quirk: instead of stopping at the 20psi target, it didn’t shut itself off until the gauge reached 21psi. This is the only pump in the test that did this.

The Fanttik X10 Ace Mini attaches to a Presta valve with or without the hose, though if you’re inflating a TPU tube, you’ll want to use the hose to avoid melting the tube. It’s one of the lightest electric inflators we’ve tested and is super easy to operate. It’s not one of the fastest or slowest inflators, and it’s middle of the pack for noise, too.

The X10 Ace Mini is one of the best all-rounders we tested, not the best or the worst at any one performance metric. And at the sale price, it easily offers one of the best values.

Fanttik X10 Ace Tiny

Despite the name “Tiny,” this Fanttik X10 Ace is almost identical to the Mini above. They’re almost the same size, and both let you attach the pump directly to a Presta valve or use the screw-on extension hose for Presta and Schrader valves.

The Tiny is a little heavier than the Mini, a little slower, and delivers one less inflation per charge. But it’s also a little quieter. The main difference basically comes down to looks, with the Mini sporting a silver finish and a brilliant display.

Personally, I’m a sucker for a good-looking bike tool, and along those lines, the X10 Ace Tiny has the Mini beat. Practically speaking: the Mini is the better value.

Flextail Mini Bike Tire Pump

I’ve used the Flextail Mini more than any of the others on the trail, and it’s proven to be incredibly convenient and reliable. It’s one of the lightest and most compact in the test, and among the trail-size pumps tested, it delivered the most inflations on a single charge. However, it’s also one of the slowest.

The Flextail Mini, like all the other pumps tested, comes with a short, removable extender hose. I’ve found it’s much quicker and easier to attach the pump directly onto a Presta valve. However, all of these pumps get very hot, which can melt (!) TPU tubes and valves. So if you’re pumping up a TPU tube or carrying one as a spare, you should also carry the extension hose with your mini electric pump, even if you don’t use it every time.

The Flextail Mini is the only inflator I’ve tested that also doubles as a safety light when mounted on the back of your bike. Another unique feature is an automatic shut-off to save the battery if the pump is running but not attached to a valve. I also like the transparent body that lets you see some of the pump’s inner workings.

Like all the pumps in this test, the Flextail Mini allows you to set a target pressure (in my case, 20psi), and once your tire reaches that pressure, the pump automatically shuts off. The Flextail remembers your target pressure between uses, as do all but one of the other pumps below.

Lezyne E-Drive

The Lezyne E-Drive offers features many inflators can’t match. For starters, it has a replaceable battery, so when it starts to fade, you can replace it instead of chucking the whole pump. We also got the most inflations from a single charge of any pump tested, other than the (non-portable) Fanttik X9 and it was the fastest inflator too.

Only the E-Drive, along with the Topeak E-Booster and State Inflator pressure gauges, offer sub-psi measurements, which is great for tire-obsessive types. Lezyne includes a dry bag with the E-Drive, which is important since electric bike pumps should never get wet. Though some of the other pumps we tested come with carrying cases and bags, none are as watertight as the Lezyne Caddy Sack.

We even managed to seat a tubeless Maxxis Dissector mountain bike tire using the Lezyne E-Drive. However, it didn’t work for another tire we tested, so don’t count on replacing your shop air compressor with this mini pump.

The clamp-on Presta chuck is nice and secure, though the E-Drive is one of the only pumps here that doesn’t offer direct inflation. That means you need to use the hose every time, which adds to the overall size and weight of the system.

Unscrew the Presta chuck, and there’s a Schrader attachment. The E-Drive delivers up to 120psi of pressure, making the Schrader attachment an option for topping off your fork. At $149.99, the Lezyne E-Drive is one of the priciest pumps out there, but there’s a good chance it’ll outlast the others. Replacement batteries are set to be priced at $19.99.

State Electric Bike Inflator

The State Electric Bike Inflator is the only inflator in the test with a floor-pump-like pump head that presses and locks onto the valve for a secure connection. Of course, you don’t have to use the hose; the pump comes with a more compact direct-connect adapter. Just remember not to use it with your TPU tube.

State is one of two pumps on test that features a tiny white LED you can turn on to illuminate the valve while you’re pumping, which is handy for early-morning or late-night ride repairs. Though it’s heavier and louder than most of the pumps tested, it also delivered more than six inflations on a single charge.

The State is the only mini pump I tested that doesn’t “remember” your preferred pressure cutoff between uses.

Topeak E-Booster Digital

Topeak is known for their innovative pumps and tire pressure gauges, and they’re currently offering two different mini electric inflators. The one I tested, the E-Booster Digital, has a unique valve selector switch for use with Presta and Schrader valves.

In the first round of tests, the Topeak E-Booster turned in a very slow zero-to-twenty time, so much so that I decided to run another test just to confirm. Apparently, something was wrong the first time because the E-Booster ended up being one of the fastest pumps in the test, clocking just under a minute in the 0psi to 20psi timed inflation test.

We tested three new pumps in October this year and found one of them — the Lezyne E-Drive — was even faster than the Topeak. However, the Lezyne was tested on a 2.4″ tire while the Topeak was tested on a 2.5″ tire. To compare apples to apples, we put the Topeak pump on the same 2.4″ tire (a Maxxis Assegai) and were unable to get an inflation time under a minute, leaving the Lezyne as the fastest in our test.

Unfortunately, the Topeak is the heaviest of the mini trailside pumps I tested. Not only that, the battery only inflated the 29×2.5″ tire 3.95 times before running out. The stated battery capacity is 600mAh, about half what some of the others, like the State inflator below, spec. Clearly, it’s not a bigger battery that’s making the E-Booster heavy.

I can’t say for sure, but the E-Booster felt like it got the hottest of all the mini pumps, so perhaps the motor inside just isn’t as efficient as the others, which would be a double whammy.
