Efficient Power Usage and Accurate Sensors – The Tire Pressure Monitoring System(TPMS) features 4 advanced external sensors designed for low power consumption, operating for up to 6 months with long service life of up to 2 years. These compact and lightweight sensors provide highly accurate tire pressure readings & tire temperature readings, the minimum error is about 3 PSI. Their easy installation and durability make them ideal for challenging environments.
Smart Chip & Solar & USB Charger – The tire pressure monitoring system uses automotive grade precision chips. The low-power transmission solution makes TPMS monitors and sensors durable and sensitive, with more stable output of tire data and longer transmission distances. In addition, TPMS provides 2 charging modes: solar and USB. When the sun is abundant, solar is used for continuous power supply and automatic charging. Otherwise, it is charged through USB cable without occupying the charging port. This allows you to focus on driving without worrying about the battery level of the tire pressure monitoring system.
6 Alarm Modes and Easily set alarm thresholds – Tire Pressure Monitoring System is designed with 6 distinct alarm modes(rapid leak detection Alarm(Can’t warn of tire blowout), High/low-pressure Alerts, high temperature Warnings, and Sensor voltage low Alerts). Once sensors and display are paired, the system automatically sets the current pressure as the reference point, simplifying the setup of alarm thresholds, alarming range: +25% > the reference point pressure > -15%
Real-time monitoring & Display tire pressure – The sensitive TPMS offers precise and real-time tire pressure detection ranging from 0 to 99 PSI, Suitable for a variety of vehicles: Sedans, SUVs, RVs, Pickup Trucks and Travel Trailers. Under strong communication capabilities, robust signal transmission can be ensured, providing consistent and reliable communication between sensors and display unit. Featuring IP68 waterproof rating, Anti-loss function and Dust-proof structure, 4 External sensors can withstand harsh weather conditions.
LCD display & Adaptive Backlight & Easy Reading of Data – The Tire Pressure Monitoring System features Vibrant color LCD display provides brighter and clearer readings, ensuring you can monitor your tires effectively, even during sunshine day or nighttime driving. Additionally, automatic backlight adjustment, enhancing visibility Under different lighting conditions for easy reading, for optimal safety at all times. Automatically wake up when the car starts, and enter sleep energy-saving mode automatically after parking, No need to turn it on and off manually for each trip. If there is any abnormality in the tire, it will emit a beep warning signal.

This TPMS is a must-have for any driver!
The solar and USB charging options mean I never worry about it dying mid-trip. The 4 external sensors were super easy to install, and the LCD display shows real-time pressure and temperature for all tires clearly. I love the 6 alarm modes—they’ve already alerted me to a slow leak twice, saving me from potential trouble on the road. It works perfectly with my SUV, and the 0-99PSI range covers all my needs. Highly recommend for anyone wanting to boost their driving safety and peace of mind!

Accurate and User Friendly
Just installed this so no comments yet on longevity. However, installs easily. Mounted in left bottom of windshield (FJ Cruiser) and solar charging works great so far; no cords but has a mini USB for initial charging or recovery if needed (I have not so far). Auto off saves battery. System comes on again when motion detected of getting in car. Low tire warning works—alerted me and I checked and topped off all my tires. Accurate to within 1 psi which is very impressive. Highly recommend this system.

So far so good
So far so good. easy to install and worked on the first try. Had solid readings all the way home on a 70 mile trip to the lake each way. used these on my tandem axle boat trailer

Works! For the money does the job!
Didn’t take long to set up, my reliable tire gauge says 35psi and the sensors read 25-26 psi . So I just lowered the low alarm setting to 20 psi. The sensors are within 1 psi of each other.Kind of big though. Any bigger they might throw the tires out of balance. The tightening wrench got bent after 2nd use. For the money…so far so good.At least I know where my psi is at each tire. I like swivel base and mounting bracket.

This TPMS is a lifesaver!
Solar and USB charging options are super convenient. The real-time pressure & temp monitoring keeps me informed, and the 6 alarm modes offer great peace of mind. Highly recommend!

Trash don’t buy
EXTREMELY INACCURATE I installed it and immediately I was already kind of disappointed because the machining of the nuts to make the sensors not back off our machine unevenly some more paper, thin where they don’t even go into a thread and then other ones are so thick that they won’t fit onto a thread. Second thing was they make this product to be on your windshield so it can get power from the sun, but the swivel doesn’t even bend fully up so no matter where you place it on your windshield the numbers are gonna be slightly washed out by the screen and number three. It’s extremely inaccurate there’s sometimes that all four readings for the tire pressure are the same and then two minutes later all four of them are different by a decent amount and same thing with the tire temperature. It said that all of them were around 90 to 94° and it was 60° outside. It’s like a little kid put this together.

Okay
I’m sorry it is not accurate at all,disappointing . It will tell if you’re tireds go below 17 pounds but I tried several times to make sure all tires had the same amount of pressure but it would always read different in all tires so I give up…. It’s good for alerts but accuracy don’t expect

Great TPMs sensor replacement
Terrific replacement for tpms sensors. Since my mazda doesnt even have the function to show pressure in each tire this is a great gadget! I have a different brands tpms system thing on my other car and i want to say i like the interface of this one better. Accurate psi reading and temperature.Easy to install and use.

I can give it a zero if I can. this thing just worked for few weeks, after that 2 caps are already not working, and now only one is working. Such a wasted of money!
