70mai External TPMS Sensor : Real-time tire pressure monitoring

If you're the kind of person who spends more time in the driver's seat than out of it, the 70mai External TPMS Sensor is like having a co-pilot for your tires. It keeps an eye on your tire pressure in real-time, so you can focus on the road ahead without worrying about what's happening beneath you. Perfect for those who live out of their car (or just feel like they do).

And here's the kicker: it runs on sunlight. That's right, the central unit sips power from a built-in solar panel, with a microUSB port as backup—because even the sun takes a day off sometimes.

Now, a heads-up: you'll need a pro to get these sensors installed. They replace your regular tire valves and chat with the central unit over Bluetooth, sending pressure updates in BAR every 5 seconds. It's like your tires are texting you their status—no read receipts, though.

Why you'll love it? Well, besides the obvious safety perks, it's a breeze to use (once it's installed, that is). The display is crystal clear, it won't hog your dashboard real estate, and it updates so often you'll never miss a beat—or a drop in pressure.

In the box, you'll find: 4 sensors (obviously), 4 locknuts, a wrench (because someone's got to do the tightening), and a user manual (for when you pretend you don't need instructions).
