【20cm/30Min Underwater‑Resistant】Ridingmark bicycle pump features a market-leading water-resistant function, allowing it to withstand immersion in 20cm of water for 30 minutes without damage. Rain, spray, or sweat—our pump handles it all and stays ready to inflate. Wipe off any visible moisture or water droplets around the valve before inflating.
【600mAh Long-Lasting Battery】Our mini electric bike pump can inflate 𝗦𝗜𝗫 700×25C tires to 80 PSI or 𝐓𝐇𝐑𝐄𝐄 tires to 110 PSI on a full charge. With an accurate pressure control of ±1 PSI and a maximum pressure of 120 PSI, it easily satisfies all your inflation needs.
【Fast Inflation and Auto-Stop】Measuring only 3.23×2.2×1.34 inches at 0.32 lbs, this mini air pump is ultra-portable. Equipped with an efficient brushless motor, it fills a 700×25C tire to 80 PSI in 60 seconds. Auto-stop halts inflation at the preset pressure to avoid overfilling.
【Universal Valves Compatibility】The tiny bike pump is equipped with Presta/Schrader valves. Note: To inflate Schrader Valve tires & TPU inner tubes with resin valves, you must use the air hose. Fits most bikes & motorcycles. The memory function only activates when inflating—idle presses won’t work.
【High Precision Compensation】Supports temperature, pressure drop, and altitude compensation with one-click calibration. Built on a professional 2.0 pressure algorithm and LED digital display, it delivers precise real-time tire pressure readings. We provide 24/7 support and a 2-year warranty.

Good pump but gets very hot
I used this to inflate two tires from about 22 PSI to 50 PSI. It worked perfectly and was reasonably quick, taking only a few minutes to get both tires up to pressure. The auto-stop and pressure gauge also worked well.The biggest downside is the heat. The pump itself got quite hot, but more concerning was how extremely hot the air hose/tube around the Schrader valve got. It also gets noticeably slower as the pressure increases. Getting to 50 PSI was fairly quick, but when I tried 75 PSI, it took nearly four times as long.It’s also quite loud for such a small pump.For emergency/portable use, I’d definitely keep it around. For pressures up to about 50 PSI, it works very well. I probably wouldn’t want to rely on it for regularly inflating tires much above that, though, given how much the speed drops and how hot the pump and hose get.

Excellent pocket size compressor, only good for small tires
I really had no faith in this thing when I first opened it up. How in the world can this little thing actually pump a tire up and not burn itself up? I have several portable compressors but none small enough to put in your pocket or bicycle tool bag. We have several bikes at our beach house and they don’t get used often so it seems every time we do want to use them we have to fill the tires up. Two tires were completely flat and this little guy ran both of them up to 48 PSI without running out of charge. Each one took a little over 4 minutes on a tire that is what I consider a hybrid between Street and trail. It certainly isn’t fast but look at the size, it did pretty well. After the first Tire I have to warn that this unit gets awful hot, almost too hot to touch. After the second Tire I had to leave it sit and cool for a minute or two. It’s really not the compressor’s fault as its size and the fact that compressed air is hot no matter what is doing the work is going to produce this issue. Anyway, I don’t have a lot of use on it yet so longevity is certainly suspect but for the price it might just be worth keeping with you on your bike trip. Speaking of that, at the time I got this it mentioned it could fill up a car tire. I don’t know if you have a half a day to wait, or if this thing would even last long enough to fill up a car tire but I would not recommend buying it for anything bigger than a bike tire or maybe something the size of a small lawn tractor.

Tiny powerful electric bycicle air pump
I love how tiny this electric rechargeable bike pump is. It fits into your pockets and is convenient to carry in my small bicycle pouch. It can pump up to 120 PSI. It is waterproof so you could use it in the rain and not worry about damaging the electric circuitry. It’s short hose supports Presta and Schrader valves, so you could pump hair for both mountain and road bikes. It is USB-C rechargeable, so you don’t need a power source to plug into and you can recharge it on the go with a portable power bank. It is easy to operate, there are only couple buttons. I haven’t used it for too many trips so it is yet hard to predict how well it will take all the beating on the roads. Overall impressed so far.

Awesome tool for way more than bike tires.
This is the coolest gadget and I really hope that it holds up!I’ve got various lawnmowers, small garden trailers, wheelbarrows, just a ton of things that have tires and I’m always finding them flat when I need to use them due to small leaks. They are never near the air compressor when I find them either, this little pump makes inflating them a snap and takes just a few seconds for those little tires to get inflated to the perfect psi.I also found that it is really good at inflating the airbags in my F350! I have manual Schrader valves, adding an onboard air setup the hundreds just isn’t in the cards…. But, I can adjust the bags anywhere anytime to the perfect psi with this little pump. Because it is high pressure but low volume it takes just a second to get the ride perfectly tuned.I’m new to this vehicle and I want to try out different psi in the bags to see how it reacts, but I’m not about to stop at a gas station and air up and down during a trip, with this tiny gadget, I toss it in the center console and pull it out when I think I want to make a change.The battery doesn’t seem to last a huge amount of time, but it is enough to air up the bags a few times and it does multiple tires in between charges. Luckily, when it is in my truck, I just plug it in and it is ready a couple miles down the road to try a different psi.Definitely worth the money as it saves time inflating to the perfect psi every time.

Great upgrade from small hand pump
I’m very impressed with this little Gizmo and it will be taking up residence in the small array of tools that I pack if I’m doing anything more than a few miles.It arrived to me with only one bar on the battery display, out of three. I promptly went to work with it without charging it up and fully inflated 2 medium/hybrid tires from from 0 50 psi. That was enough to make it feel quite warm.That was also enough to get rid of that last bar on the battery display, so I took a break to let it cool and charge. The listing here says 45 minutes to charge. I don’t think it even took that long to get a full charge. At this point. I went back out to the garage where I have several bikes that rarely get used. In pretty quick succession, pausing only once about halfway through to let it cool, I was able to inflate six tires from zero to plenty-good-enough. (Two were small road bike tires set to 100 PSI, and the others were hybrid tires set to 50/60 PSI.) I still had a bar left on the battery charge display, and I’m quite certain I could have done at least one more tire, but by this time the display was reading “Hot.” This is a feature I hadn’t known about. It’s a nice feature that it gives a warning when it’s getting alarmingly hot. This warning should probably not be ignored.For such a small thing, it is impressively loud. Between the loudness, the heat generated, and my worry that this tool probably has a finite lifespan, I don’t plan to use it when changing tires at home. I would use it regularly to top off bike tires that haven’t been used for more than a week, where it’s quite convenient and will do the job quickly. I think when I’m at home and going from zero pressure, either changing a tube or tire, I will continue to use a nice big bike pump and get a wee bit of exercise without hurting my ears.RidingMark, the manufacturer, has another model listed in their store with very similar specs, listed at more-than-25% lower price than this one currently, that is just a few grams different in weight. The only remarkable difference I can tell from the listings is that this one has a decent waterproof rating where the less expensive one doesn’t. I haven’t, however, held that one in my hand or tested it, so I can’t say with any authority that it will perform as well, but it appears to probably be a prior model.Not having a clip on the body of the pump to hold the hose for storage or backing, is a small mess on the design, but I don’t think it will be prone to getting lost in the the smallest assortment of tools I keep packed in a bag within my bag: Park tool, this pump now, tire levers, patch kit, a couple Allen keys, and screwdriver.The difference in either weight or volume between this and the small hand pump I’ve carried for many years is negligible. This has the great advantage of setting the desired pressure and pressing a button to get to it. I’ve never carried a tire gauge with my tool kit before, so in the past when fixing flats in the field, I was just guessing what pressure was good enough. I probably wasn’t getting road bike tires nearly up to 120 PSI either. This is a great improvement.

A handy item to have for when you’re in a pinch
I recently got back into cycling after years of staring at my Schwinn taking up space in the garage, and I had no idea how many inner tubes one can go through just riding around on public streets and bike paths. We’re not even talking rugged mountain trails with their numerous gotchas lurking at every bumpy turn. I was tired of hauling out the giant car tire inflator before seemingly every ride, so I was excited when this little handheld inflator from Ridingmark came my way.This AS290 model quite literally fits in the palm of my hand and weighs just a few ounces, making it, I suppose, convenient for packing into a saddle bag and having with you when you’re on a serious long ride and need to pump up or change out a tire. Since most of my rides are around the neighborhood, I have yet to take this with me, but I sure do appreciate the ease with which I can attach it to a valve in my garage and be at the proper tire pressure in a few seconds. Let me just say that this convenience does not come without some caveats. For starters, if you use it with a Schrader valve, you will have to use the included tube attachment, which is about 3 inches long. Second, this sucker is loud. It sounds like a swarm of angry hornets when you start it up, and if you need to run it for more than a few seconds be prepared to burn your fingers when you have to detach the tube from the valve stem. I took my two tires from roughly 20 lbs. up to 60 lbs. each and was seriously concerned about overheating, although it got through the task with about two-thirds of a charge still remaining. That’s useful to know if you take this on the go. Just be sure to charge it up ahead of time with the included USB-C cable.The pump controls are intuitive to set even without the included instruction booklet. A long press on the power button gets you started, hitting the + or – buttons will set the target pressure, and then once you attach to the valve you hit the power button again to start inflating. The pump shuts off when it reaches the target pressure. There is a rubberized door on the left side that protects the inflator and charge ports from water, which isn’t much of a concern for me when I’m just using it at home.I paid right around $60 for this when I ordered it for review. You’ll do much better than that (and honestly should) at current prices. High marks for convenience, mild concerns about heat generation, and no opinion yet on durability; I’ll revisit this review if things change. You certainly might want to consider this product if portability is a consideration when you are on a serious bike ride that takes you far from local services.

Lightweight, portable mini pump
Mini-pumps are my impulsive-bike-component-purchase-kryptonite. The reason being that they’re so useful, make great gifts for people, and anyone who rides bikes knows how critical an inflation device is when you get a flat on the side of a trail. That’s why these are so awesome. They pack away easily into any small pack/bag/downtube storage and you can just forget its even with you until you need it.This mini-pump is shockingly lightweight. I’ve got a handful of others, but this one feels like its the lightest one I own. Now that could be a double-edge sword — the lightness could very well be because the battery isn’t as big as the others — but so far that hasn’t been an issue. I was able to inflate 2 mountain bike tires with this without running out of battery and that’s good enough for me, if I’m in a situation where I need more than 2 or 3 inflates with a mini pump my ride is already over.The noise level on this is typical with most other mini pumps, its loud but that’s because it has to be. The ability to set a pressure, start the pump, and go do something else while it inflates is also nice because it auto stops at exactly the right PSI.As mentioned I use this for my mountain bike tires, so high volume low pressure is the name of the game. 29″ tires at 26-28PSI means the pump works for a while but doesn’t need to force high pressure into the tire, maybe that helps it last longer, not sure. But overall this thing is fantastic. It worked for my Presta valve bike as well as a bike I have with Clik valves using the Clik adapter I already owned.

Nice little light, good quality, works well.
Really seems to work well, and simply amazed at how small it is! This thing is tiny, but worked very well to bring my ebike tires up from 8 to 28 in about 1 minute.The air flow is very minimal however, I certainly wouldn’t use this to inflate tires with a large volume. Not for use in car or truck tires, maybe lawn tractor tires, but that’s about as big as it could handle. This is certainly designed and reccomended for bike tires. And for that, it works well.It is rechargeable and can be easily carried in your pocket. It is quite loud when operating, not a quiet little pump, but works. Once turned on, you set your desired pressure, attatch to your valve and turn on. It will automatically stop pumping when it reaches the set pressure. The pump is capable of 120psi, bit in most cases, 20 to 40 is normal.The screw on air stem is easy to screw on and attach and the tire stem is easy to attatch as well. The air stem does get quite hot during inflation, but the pump stays relatively cool.The whole unit is well made, easy to operate and seems to be of good quality, no complaints with this unit.
