This unit does not use usb cable. And it is not made for Tesla.

I tested it by checking the temperature at the bottom of the inside metal container:

Cooling, starting from 75F/24C:
5 min: 48F/9C
10 min: 39F/4C
15 min: 35F/2C
22 min: 32F/0C
It then remained at about 32F/0C.

Heating, starting from 75F/24C:
2 min: 115F/46C
It then cycled between about 115F/46C and 125F/52C every 30 seconds.

Inside metal container:
Inner diameter: 2-5/8" (67mm)

Plastic base:
Outer diameter: 2-13/16" (72mm)
Depth: 3" (76mm) with both pieces or 1-7/8" (47mm) with only one piece.

It fits well and is stable in my 2022 Tesla Model 3. Even more stable with a rubber insert in the cupholders.

With the button-side pointing towards one of the seats, it hangs over the side of the console by about an inch (25mm) and doesn't cover the other cupholder. This isn't a problem for me.

It's well insulated, with almost no heat felt on the outside plastic while in heat mode.

It says it works best with a metal can, but I think any type of metal drink container would work fairly well - maybe less so with double-wall containers with an air gap. Check the diameter of the cup you want to use, as this isn't overly wide.

It also holds a 500ml plastic water bottle and is able to keep the water chilled inside it.

The digital display shows the temperature in Celsius only and is not configurable.
