They promised to deliver by July 23rd, surprisingly, but I already picked up the small package at the post office on July 24th. Incredible delivery speed. 17 days to Moldova.
The included battery has 3.17V. The technician lowered the voltage to 2.0 V and the screen lit up. At 1.9V it no longer turns on. I don't know if it will measure pressure at this voltage; measuring pressure with soldered wires and a laboratory thermometer is not entirely convenient...
Consumption 0.5...0.8mA in the range of 2.0...3.2V. In standby mode, it's less than 1 µA.
I soldered 2 batteries of 1.5V each (voltage 2.95V). At 2.95V it shows the same pressure as at 3.17V. I compared it with a mechanical pressure gauge - both show the same readings at 2.00 and 3.00 bar, but at 5.5 bar (mechanical), the electronic pressure gauge shows 5.8 bar.
Both keychains show the same pressure, with a difference of up to 0.01 bar. How did they do this? I don't know. There are no trimming resistors on the board.
Two weeks of delivery by Russian Post.
excellent tester
Everything is fine, the order was received on time and corresponds to the description. Thank you.
fully corresponds to the description
in my case it measures accurately, with a difference of 0.1-0,2bar
All good! Came very quickly, under two weeks. Battery was included, it works as it should. I haven't compared the readings against a service station compressor meter, i will add an additional review later.
This is the third time I order this gadget.

Dear Wilson,
We have successfully delivered the missing items. Please check your email for proof of Delivery.
Very convenient as a keychain, the tire pressure gauge is always with you.
Works great.
A fully working pressure gauge, there are different pressure measurement systems.
Thank you! Arrived quickly. I haven't tested it at work yet, I hope it won't let me down.
It came with a battery, works perfectly (this is not the first time I order). With other pressure gauges, the readings match.
Recieved item as discribed, delevery time was good. It measures the pressure very well. Need to compare the values with calibrated gauge.
The keychain works great.
Fast delivery, the readings match the mechanical pressure gauge, I will determine the error using the reference gauge. I recommend the product
So far everything is fine, I just received it, tried it, everything works well! Let's hope it's long enough!
Works, comfortable to use. I didn't check the accuracy.
fast delivery product works everything is fine
Working! I recommend!
It works fine, the battery is already inside.
You can switch pressure measurements for someone who is used to it.
Received. Tested on the wheels of my car it seems to measure well.
I haven’t checked it yet, I attached it to the key fob and it still dangles there.
Exactly shows!
excellent product I recommend 👍
Works fine. Excellent purchase for your own price!
One wheel was enough to measure, then it shows 0 and does not respond to pressure.
Great! If only the pump was pressed iron, otherwise it would be plastic, I’m afraid it will rub out quickly

Let customers speak for us
I liked this jump starter, I tested it and I am satisfied. The vehicle had a low battery, I connected it and it started quickly. A tire deflated and I inflated it. practical and very useful

great piece of equipment tires and battery covered, keep in my top box of my Canam spyder.
Easy to operate, auto stop inflation function is really practical.this is a very good product, thank you Autoxmatch
Compact and powerful, saves me when car battery dies unexpectedly.
Must-have for drivers! reliable emergency helper for road trips.
Works great for jump starting my car, inflator is super handy!
Love the integrated air compressor function! i use it to inflate car tires, bike tires and even inflatable pool toys. preset pressure modes are very convenient, it stops automatically once reaching the value i set. no need to carry a separate tire pump anymore, saves lots of space.
Fast shipping, multi-tool solves flat tire & dead battery problems.
Solid build quality, fits well in car glove box, totally worth buying.
It arrived almost on time. I haven't tried it yet, but it looks good and the battery was fully charged.

This jump starter has saved my butt more times than I can count. I spend a lot of time outdoors where there’s no cell service, so when your battery dies, AAA isn’t coming.
This thing is incredibly easy to use, starts my vehicle every time, holds a charge for a surprisingly long time, and is small enough to fit in the center console. The built-in flashlight is a great bonus, and I love that it can also charge my electronics on it.
