Hi Mi Fans,

In this episode of XEGG.Review I will demonstrate the 70mai TPMS Lite.
70mai is the only company in Xiaomi´s Ecological Chain that´s fully focused on making products for the automotive industry. One of their most known gadgets are without a doubt their high quality Dash cams which gained positive reviews from all over the world. This only tastes for more! getting excited? Continue to read the article!

What is the 70mai TPMS lite?
TPMS stands for Tire Pressure Monitor System.
The 70mai TPMS Lite is a device that monitors pressure and temperature of tires in real-time which are displayed on a receiver.
As soon as the receiver measures abnormal changes based on the standard pressure and temperature, the TPMS will turn on its alarm to alert the user.

Who needs it?
The TPMS Lite can be used for most 4 wheeled cars.
With a range up to 10m it is possible to install the TPMS on trucks.

Why is it called Lite?
This version is easy to install because of the external sensors (Valve caps)
70mai released another version earlier including sensors which needed to be installed inside the tire.

The 70mai TPMS comes in a black box and is given the following modelname: T02
Back (Label)

Even though its a very compact box, 70mai included everything you need (and a little bit more).

Packing list:
1x Receiver
4x valve caps (external sensors)
4x Anti-theft hex nut
1x USB cable
4x Pressure warning stickers
1x Battery removal clamps
4x spare waterproof rubber rings (Valve cap)
1x Metal Wrench
1x User manual

Design + Features:

TPMS Lite Valve Caps:

the Valve caps are external sensors and need to be screwed on the tires air valve.
It measures the air pressure and temperature in order to send it to the receiver.
To make it more easy, each valve cap is already assigned to a particular tire.

LF=Left front Wheel
RF= Right front Wheel
LR= Left Rear wheel
RR=Right Rear wheel.

**each valve cap comes with its own unique ID (CXXXXXX).
Within the 70mai APP, you can swap the valve caps when assigned wrong and bind/pair new ones.

Valve Caps
Air pressure Range: 0.0 to 8.0 Bar (0 /100 psi)
Working temperature: -40 to 80C
Storage temperature: -40 to 85 c
Air pressure Acurracy: =- 0.1 bar

The valve caps are designed to last long.
They are completely dust free and waterproof.
Rated as IP67 and work within all weather conditions.

The core of the valve is made out of copper which means it can manage high temperatures and is also resistant to corrosion.

The battery that's inside is a CR1632 Lithium Cell (3V, 140 mAh)
On normal use, the battery can last up to 2 years.
A rubber ring seals the valve cap perfectly.

Whenever you need to replace the battery and one of the rubbers are worn out or snapped, 70mai included spare rubbers just in case you need to renew them.


The receiver is a small lightweight hard plastic unit and designed to fit on each dashboard.
The data from all 4 external sensors (Valve cap) will be shown on the display.
It comes with a 500mAh battery that can be wireless charged with the help of the solar panel on top.
When placed out of the sun you can charge the receiver with the Micro USB cable 70mai included.
You can connect to the receiver over bluetooth using the 70mai APP.

-Installation of the valve caps & Receiver
-Test the responsiveness
-How the perform a battery replacement

70mai APP:

70Mai developed a mature No-nonsense APP.
Besides checking the current data you can :
Adjust tire pressure according to the standars of your car.
Temperature alert
Swap Sensors (When placed in wrong order)
Bind (New sensor)
Change brightness receiver
Adjust sensibility Receiver will wake up.


Easy and fast installation
Very well designed
Anti Theft
Air pressure is very accurate
Solar Charged
Bluetooth connection
Spare rubbers

The temperature sensor could be a little bit more accurate
Somehow I would love to see a 70mai logo on these valve caps

The 70mai TPMS Lite is a great tool to keep track of your air pressure on all tires.
Instead of guessing, you can see the actual data immediately.
As soon as I notice the pressure is lowered for 2 days I'll take out the 70mai Compressor and bring it back to the correct BAR.
Keeping your tires on the correct pressure will increase the tires lifespan and save money on fuel.

Last but not least, safety is most important!
Since it measures the pressure narrowly, it wont take long before the TPMS will alert you something is wrong!

I would recommend this device to any car driver without an pre installed TPMS device.

You can order the TPMS Lite directly from 70mai own online store:
