It probably does produce water, though considering the amount of air passing through it, the amount of water would be proportionally smaller and probably wouldn't build up enough under normal use to be noticeable.
It took me more than an year to realize you can screw off the air hose on the model 1S. I thought my unit was developing an air leak, then realized it somehow came loose. Now, it is much easier to pack in my rucksack.

I am convinced that the service life of the piston and cylinder would be drastically increased if the hose was periodically unscrewed and some silicone oil was sprayed directly into the piston. Silicone oil is beneficial to plastic, rubber and metal.
I had mine but it's universal version which is great ,and i find it much better compare to my michellin tire inflator which is the battery goes low with just adding air on my tires,the only thing that i like about michellin is the design,but this xiaomi has better battery
Cool video and amazing product. I realy wanna know how precise is the pressure indicated on the product comparing with a good barometer. Do you have that info?
Hi. Would tounhave a video tear down of the 2s? I need to know how to do it because i need to clean the pressure sensor part. Im having issues with mine stopping sbruptly and not continuing to pump. Thanls
Hi, I didn't know the 2S was out already! If you meant the 1S, I have an older video on my channel of it. The pressure sensors don't seem to have changed much between generations.
@@jasperaguila5513 If I'm not mistaken, the pressure sensor itself is mounted using two screws on the side of the housing of the sensor hose end. You would be able to remove it this way. I'm not sure if the main hose or any other hose is unscrewable, which may help.
It would be so nice if they added an extra power port and extension cord, so you could run of day a car lighter system. I think for the form factor it's a pretty nest device. I'm bit familiar with this form factor, so perhaps and probably there are better ones
If I had to take a guess, the lack of a power port on the device is also intended to indirectly limit how long you can use the device at one time (i.e. to prevent overheating). It's possible that the device would burn out if you were to add this feature and operate it for an extended period of time.
@@liminalsunset but it then could easily have a timer or temp measurement, I'm just free balling. I understand this device has its limits die to its form factor. I think it's still a nifty device. I bumped into it today as a shop here on the island sells a 1s. But hen I noticed there is now a V2. That's got me googling and looking at reviews. I think I prefer the V2 and would order it online vs buying it locally
Thank for great video. And after watching, I got an idea to mofify the pump by adding connector with a switch that can bring external ~8V DC source to motor pump (12~15V to 8V DC-DC conversion). That will save energy from internal battery and extend use for car/motorcycle on the field. Of course, initial pressure (e.a. from 0 to 30psi) will be manualy controlled for multiple tyres and final pressure (e.a. 32psi) will be by switcing to integrated battery and automatic stop when wanted pressure is reached. What is your opinion for that?
My opinion is that a better way to accomplish this would likely be to simply have a switch that allows you to power the device either from the battery or the external power source. This way all functions of the device are kept. As long as your external power source can supply 40 watts or so continuously, it will run fine. You should ensure that the battery is disconnected during this operation, as this charge rate is likely far too high for it. On the other hand, the battery power provided should be sufficient for most uses. As seen in the test, generally, charging for half an hour will be enough to fill one tyre of a car from empty.
I think that disconnecting battery pack and external powering whole unit with pump voltage (7.4V or above) will destoy charging and mesauring part of device. Also, my opinion is that unit is charged by 5V and battery is leveling charged for every cell. So thats why I suggest to external power pump motor only. I didn't open and measure voltages of my unit and that is why I asked you for optnion. Anyway, thanks for fast answer.@@liminalsunset
The reason for the capacity difference is that the batteries are two smaller ones in series, and in a phone there is effectively one larger battery in "parallel" so to speak. The amount of power stored is voltage times amp-hours. Thus, the battery in this device is actually equivalent to a 4000 mAh phone battery. The reason it is not 5000 mAh likely has to do with your other comment, because the power output (sustained) of these batteries is higher.
Hello Larry, Congratulations for this excelent video. One question, this us actualy a Xiaomi product?, why do not appear the orange “mi” logo on the box, nor on the product? I just bought one of this in Aliexpres and just yesterday I received, having the doubt where I have been cheated giving me an good imitation.
the rounded M Mijia logo is a sub-brand of Xiaomi. Xiaomi usually only uses the orange logo for Xiaomi branded products and not the Mijia ones, similar to how Honor and Huawei are made by the same company but don't have the same logo
dude they aRE BARLEY DIFFERENT.. they just made a second version so sell it for 70 instead of the 30 dolar price we were gettting... capitalism at its finest puke

This is what I call a quality review! Lots of details! Thanks mate!
Earned a subscribe mate!
Quality teardown and comparison which is very rare these days :)
Man, it's been a long time since I've seen a real review and not just an ad. Thanks!
Jeez man thats an in-depth tear down. Nice one.
The music is so annoying
thank you for review but please cut that nails :D
How to fix not changing in 2
This is an awesome comparison, your voice is calm as heck - could pass off as an ASMR channel tbh.
Amazing review! Do you know how accurate the chosen pressure is from the pump? If you input 35psi do you get 35psi?
Wasnt expecting an actualt teardown, cool video man. They inside looks beautiful on both if them, all black. Very impressive
Best comparison ever I have seen. 👍

mine is 2 version
Incredibly detailed review! Thank you very much.
Holy mother of Xiaomi air pump teardown!!!!
Could you please link the product what you use at 4:13 to disassemble the mini compressor? thanks!
Go on AliExpress and search for "curved screen disassemble tool" or "stainless phone disassemble" or similar and you'll see it
Yep, also leaving a comment to boost the video. Always appreciate someone that actually goes into details in a review.
is that an 18650 battery cells?
Yes, they are using LithPlus 18650 cells in the 2nd gen. I do not know if they use different suppliers for different batches.
Nice video man, i juat wondering if this device produces water just like conventional compressor?
It probably does produce water, though considering the amount of air passing through it, the amount of water would be proportionally smaller and probably wouldn't build up enough under normal use to be noticeable.
@@liminalsunset right, thanks man
Is there any grease in the piston on version 2? I know that on version 1 everything is dry like in the desert immediately from the factory.
I’m still wondering what that blocked out button does. Have you checked?

Wheelchair tubes are usally high preasure ones... the ones i use say 85 to 140 psi or 56 to 10 kg... luckily i bought a version 2 and works fine
Bro, can you compare the Xiaomi Air compressor 2 to the Bosch EasyPump ?
Hi. Would tounhave a video tear down of the 2s? I need to know how to do it because i need to clean the pressure sensor part. Im having issues with mine stopping sbruptly and not continuing to pump. Thanls

@@liminalsunset got it. Let me try that out tonight when I get home. Thank you for the tip!
Are they safe to be put inside the under-seat of a motorcycle?
So, can you easily swap the batteries for new ones?
amazing video, u won another subscriber
Perfect video man! Subscribed ;)
All clear now, Profesor! THX.
My inner nerd is so satisfied with this great analysis
Kanal NICHT EMPFEHLUNGS WERT = Zuviel Werbung.
Doesn’t the previous one work on scooters?
Great work done. Respect!
The best review i have ever seen🌹🌹
This is the best review ever!!!
great work and review
best review on the internet
great review mate! thanks

I believe it can not charge and pump at the same time, at least 1s can not
amazing!
Insimply van not understand why they can't out in a much bigger battery. I mean my phone already has 5k mAh how can this have just 2k?!
I guess the battery is 2kmah because it produces more amp vs a phone. I'm sorry for dumb question, I'm not really familiar with this kind of stuff
The reason for the capacity difference is that the batteries are two smaller ones in series, and in a phone there is effectively one larger battery in "parallel" so to speak.
