This device - advertised as a Car Solar Wireless TPMS Tyre Tyre Pressure Monitor has turned out to be wonderful. See the photo of the device sitting on my car dash (2 brackets and an adhesive pad supplied - I used the latter) which also comes complete with manual and 4 tire sensors with a claimed battery life of 5 years. Note the lack of wires.
Here is one of the sensors which replace normal tyre caps, attached to our Honda, where they will stay for the next few months here in the UK, before being transferred to our little Spanish car in the spring.
So, what is special about this unit? Well, it charges from USB OR from the sun, so no wires needed. Indeed while working on another article and forgetting that I didn't have a photo of the unit, I left it mounted on my dash as you see, collecting energy from the "sun" - I say that laughingly as I don't think the Northeast of England has seen any sun this month - certainly not since I opened this unit - and yet, there it is after sitting in the car all morning, fully charged.
So, the wireless sensors outside on the wheels take seconds to mount - and I've done NO setup. I believe from the manual I can do lots and I will when time permits - but here's the thing - when I got back to the UK last week, I came back with a dodgy rear right wheel which lost a lot of pressure (from 33psi to 22psi or thereabouts) in a matter of days - twice while over in Spain. The thing is, I didn't trust the air supply gauges in the rural villages over there, I suspect some of them were last calibrated just after WW2.
We knew we had a problem with at least one tyre but were not exactly sure of the scale. When we came back to the UK we went to a modern garage on the way up North, filled the tyre and measured all of them. Three were as they were supposed to be and then this TPMS monitor arrived from Banggood. It worked first time and I quickly tested the wheels (by then fitted with the sensors) and as a result, we took the car to Quick-Fit who confirmed that just the one tyre was shot - a screw apparently - and sadly also confirmed that the tyre was not fixable. Meanwhile, the other rear tyre got a fixable nail puncture,
The upshot of that was the purchase of two new front tyres with one of the original fronts replacing the damaged rear - all calibrated and set up by Quickfit so we know the readings we have now are accurate. In the future (we do a lot of travelling) I will be happily using this gauge to keep an eye on tyre pressures and temperatures (after a short time, transferring to a different car unless I buy a second unit) and no longer worry about the accuracy or otherwise of rural petrol station gauges. Good gadget. One less thing to worry about. And no wires - that keeps Maureen happy.
Do we have gripes? Just one - that pesky audio alarm - that's coming off. Other than that, great.
Good gadget - and Andreas Spiess has found other uses for these. Be sure to check out what he's doing.
