Cordless Bike Tire Inflator Air Compressor - Zacro 150PSI Electric Battery Powered Mini Bike Air Pump with PSI Gauge and LED Lights, Fit for Bicycle, Cars, Motorcycles, Ball [Included Portable Bag]

Pro:It is small, like a can of beer. The hose slots inside the hole when not need. The bag has velcro straps to attach it to bike frame.The memory psi for car bike and balls can be adjusted and it remembers.Battery last long. Used it for topping up fat tires bike and car tires. Don’t need to charge often and don’t seem to loose charge when stored.Cons: no good place to store the accessories pump attachments.The lcd is too dim to see outdoor. Really really hard to see.

This a great air pump. It works much better than any little hand pump you can put on you bike. Doesnt tire you out to pump up your tire to the correct air pressure, not just enough to get you home like the hand pumps. You've got to be Heman to pump a tire to pressure with a hand held....

Charges easily and inflatge quickly

Super easy to use accurate description easy to carry

It's a great little tool, but seriously - it's much faster to pump the air in by hand. I went ahead and hand pumped the other 3 tires up by 2 pounds each while waiting for this one to add two pounds to the rear tire. Would be excellent for folks who are unable to use a hand pump, that's for sure.

Excellent small bicycle compressor! Very nice fit and finish. For the dummies who are returning this because they supposedly didn’t receive a hose, it’s recessed within the main body! Just pull it out and attach it! Love the digit pressure settings so you can attach it and let it run. It will be a permanent attachment to my heybike mars ebike that I bought off of Amazon and absolutely love!

The media could not be loaded.  Small, quite light pump with a convenient storage bag that has velcro stripes to attach to the bicycle frame. I pumped the bicycle wheel today, it took literally less than half a minute from zero to full. I was reluctant to use the preset value, so at first I was gradually increasing the pressure limit. 1 PSI increase in the bicycle tire was taking a few seconds. A bit loud but very fast.

This pump is very easy to use. I use it to adjust my car tires & bicycle tires.I especially like how it connects (screws on) to the tire stems for leak free connection.The display mode icons is very hard to distinguish, so I just know the one on the left is for car mode.Now, I just hope this unit will last.

The Zacro Portable Air Compressor is easy to use and pretty powerful for a small unit. The air compressor has a sleek, durable body with a large, easily readable LCD screen and an intuitive control button. The compressor reads the current tire pressure on my bike tires and it's very accurate because I compared it to my manual pump. It inflates my tires quicker and easier than with my current floor pump which costs even more than the compressor. It comes with four different tips so I can use it on a variety of tires, including bikes, balls, motorcycles, cars and inflatables.I love that I can preset the ideal pressure on the compressor, as specified by the tire manufacturer. The compressor then remembers this air pressure every time for a super quick way to pump my tires. The maximum air pressure of 150psi is more than I need for my hybrid Giant tires, which only need about 80psi. This pump will also be good for road bikes. It's versatile as I can use this for balls as well as smaller inflatable boats, as well as car tires in an emergency. On the downside, it does take a bit to inflate car tires, but it will do ok in a pinch. Overall, this is a handy air compressor that's great for pumping bike tires and more. Full marks from me!

The media could not be loaded.  I have used this wireless compressor a few times now on single charge to inflate the tires to normal pressure on my ATV and trailer, no issues found.It was very satisfying, pulling this out from storage box and use it, right the way without wire to plug in, no long hose, no guess work or additional pressure gauge to use, It’s all in one build in, portable, light weight and works great in the field or road for a car, many bicycle tires or off road toys and sport balls or beach toys.Of course, this little air compressor is slower to build up pressure in tires than a shop compressor and that is normal, as expected for its size and the 2500 mAh battery capacity.Some points I liked:1. The preset and adjustable pressure settings, stops compressor automatically when pressure is reached. Also, displays the current air pressure in the tire when attached to compressor and during use. Accuracy was right on and verified separately with my pressure gauge.2. Good compact design to store the 6” air hose in the compressor when not in use and easy to setup. Also, no pressure loss when installing or removing the hose from the tire valve. This is because the tire adaptor is the screw on type instead of press and clamp.3. The storage pouch with long Velcro straps to attach on the bicycle frame is ok but should have a compartment for the small attachments instead of plastic bag.The cons:1. Battery capacity is just ok.2. The control buttons, all work but too close together, it is hard to press the correct button with gloves on or with big fingers. Also, no back LED lights on buttons to see them at night.3. The screen display is ok to read the info better at night compared to day light in the sun, not much they can do about that, as an improvement.Overall, I didn’t notice any heat build up on the compressor, just a bit on the hose ends, good value, great quality materials and design, looks sturdy and hope the pump will last a wile.Thanks

I've been using electric tire pumps for my e-scooters and bikes for quite a while, and they do have some advantage over hand or floor pumps, although, I prefer using a larger compressor to fill deflated car tires (or else it takes too long with a small device like this). I do like that this pump comes with a case that can be mounted to your bike frame or seat post, but the case does not have any rubberized backing to prevent it from slipping, nor does it offer any padding to protect the pump from vibration.The pump itself is fairly compact, but about twice the thickness of my go-to electric pump. This may not be an issue for most people, but if space is a premium, then this may be too big to carry on your bike or in a backpack. Fortunately, this pump charges via USB-C and the valve tube is stored neatly in the housing of the pump. You get various nozzle attachments, including a ball and presta valve adapter, but I've only been using it with the standard Schrader valve. Unfortunately, the included Schrader valve is terrible at keeping air in, and I find that I lose a lot of air while removing the valve. On a hunch that it was *not* me, but the valve, I grabbed a valve off another pump and used that with this pump - no air loss. The included valve is not great quality, but you can replace it with something better. You should even be able to use a valve extender, which often helps to prevent air loss when connecting/disconnecting the valve. As with most electric bike pumps, you can set different modes (i.e. car, bike, motorcycle) and it will save the pressure value for the next time.  You can change the unit of measurement between PSI, BAR, KPA, and others, which is a very good thing! As for performance, this unit is pretty quiet - more so than my other pumps - and pushes air faster than the average electric pump. In conclusion, provided you replace the tube valve with something better, and you are ok with the size of this pump, it is pretty good overall!

We’re a sporty bunch with about half a dozen bikes (never mind several cars) that does much of our own bike maintenance. We’ve tested out about a dozen different electric inflators with this “tube” form-factor being one of the more common ones.As inflators go, this one is accurate, quiet and quick. We especially appreciate that the hose can be stored in a slot in the unit which saves a tonne of space. Functionality is very similar to others we’ve tried: set the mode you want (a pictogram indicates things like car, bike, “user” mode, sports balls), select the pressure with up down buttons and hit start. It’ll stop when target pressure is reached, and it measures as accurate, tested against other digital pressure gauges.We have a few gripes, however.First, the display is a bit difficult to read. Not a deal-breaker, but we wish the pictograms and scale indicator (PSI, BAR, kg) were larger.A bigger gripe we have is that certain modes default to PSI and others to BAR. This makes ZERO SENSE at least to the North American market: we deal is PSI for 100% of our inflation pressures. Yes, things like car tires are often double-marked with PSI and BAR, but virtually no-one uses “BAR” as a unit of measure day-to-day. You have to manually reset the pressure scale for those modes every time the pump is powered up. Frankly, we’ve taken to just ignoring those and using the modes with PSI by default.Overall, we like it in use but we’d suggest you look at other units available that address the above issues, for example, one branded “Dexpole” with Amazon ASIN B0965KZ6MH.Still, it gets a “very good” rating from us as it’s functional and accurate.

If you have never owned a pump and are lucky enough to live close to a gas station with access to a free air compressor, you may assume that having your own portable one would be unnecessary, and for the most part, you would be right. However, if you own a bike, scooter, trail stroller or inflatable mattress, you would be wise to invest a little money in having this convenient tool on hand.As a winter bicycle rider, having a pump available at the ready is essential. The cold air tends to lead to a quickened loss of air in tires and in order to keep my ride safe, I make sure my tires are properly inflated for each ride. This portable air compressor gives me an accurate reading of where the pressure in my tires are at and allows me to inflate them on the go.For our jogger stroller, the front tires get sluggish in winter due to the cold air as well, and I don't need to have more work pushing a frumpy tire through the snow.I found that while the larger areas to inflate (mattress) tended to take a long time to complete, which is fine, it is not overly loud or anything.
