Digital Bicycle Tire Inflator Gauge with Auto-Select Valve Type - Presta and Schrader Air Compressor Tool

I use this on bikes and cars. It quickly adapts to presta and schrader valves with little/no adjustment. The gauge seems pretty accurate, too.It's probably a bit underbuilt for use in a professional shop, but for home use it's perfect.I got it for setting up tubeless tires on bikes and it works great to give a fast shot of air (with valve core removed) to set the beads. This tool made the often PITA setup a LOT easier.

I bought this to use with tubeless bicycle tires. Hadn't needed an inflator before for presta valves. But tubeless bike stuff has a learning curve and a clip on inflator is a major timesaver when doing these installs.It works right, is well made, and sturdy.This will replace my Schraeder-only inflator. Which is not very old. But there's no reason to have 2.I've had it just a few days, but it's been spot on.My only regret is, I recently saw a better air chuck. The better one looks far easier to clip to a valve. Operator presses the chuck onto the valve and then squeezes a trigger to attach. It's a better, one handed, method.Currently the new style is overpriced, I might buy one if they come down in price. I bet the new style becomes the common type some day.But conclusion, this inflator is great. Big timesaver with presta valve bike wheels, plus it also works on normal schraeder style.I'm glad I bought it.

This is great for bikes and other tires that have a long valve stem. This barely works on car/truck tires that have TPMS sensors since their stem design is typically shorter and will not full insert into the inflator. To correct this, you need to replace the small spring (see photo) that pushes the plunger into the Schrader type valves that cars and trucks typically use. The shorter spring in the photo is the one that comes with the inflator. The longer spring is what I replaced it with and it works great.

I just bought a nice Specialized Sirrus 5.0 and it is my first bike with Presta valves. I wanted a nice accurate gauge to go with it so I purchased this one. It works flawlessly with both Presta and Schrader valves. Don’t believe the review that said otherwise. I doubt they understood how to prep the Presta valve prior to pumping. What really impressed me was the fact they included nice Energizer batteries with the gauge. It also came with a nice little case of spare parts and a couple of Presta valve caps that came in handy, as my bike didn’t have them yet. Great instruction sheet as well.

This tool is awesome! Works flawless on presta and Schrader valves with no issue at all. Very easy to use and so far has exceeded my expectations by a long shot.

Left it attached to bike tire for 8 hours and neither leaked air. I wish the head was metal though but great for the price.

Something went wrong after using it less than 5 times. The air wouldn’t stop coming out. Very disappointing. 2nd item I bought from this company and both items failed.

I purchased this inflator to use with my compressor to rapidly set the bead and fill tubeless bike tires. The inflator seems to be well made and has a pretty easy to read pressure gauge. Overall, if you are someone that is going to install a couple tubeless tires every year or so - this will work. It will annoy you a bit, but it will work. If you are going to do more tires per year or if you have a bike shop - this is NOT what you are looking for. Here's the things to be aware of:- The "universal valve head" will NOT lock on to a Presta valve that has had the core removed. I prefer to do the initial inflation with the core out (after filling with sealant), because it fills and locks the bead very fast. To use this inflator, you need to put the core back in first. It will work that way - just not my preferred method.- In order to lock the head onto the valve you need to push down very hard. I mean really hard. (even the directions say this). If you don't, it won't lock on and inflate.- While you are inflating, the pressure gauge is all over the map. Once you stop inflating it takes a moment or two and the gauge settles down and reads the pressure. I didn't calibrate it - but it looks like it is in the right ballpark.Bottomline - this inflator works. But it's quirky to use. I probably would have ponyed up for something higher quality if I were doing it again. Not worth returning though - I'll live with it until it breaks. Hope this helps some of you.
