How do I run power to a USB-C powered sensor? (lemmy.nz)

I'm just bought an Airgradient air quality sensor (actually two, an indoor and an outdoor).

I want to mount the outdoor one but it needs a USB-C power supply. I can run a cable but power isn't exactly close. Do I somehow find a 10m USB-C cable and run it through the roof to the sensor that I mount on the side of the house? What's a normal way of getting USB-C power to an area far away from the closest power point?

I really doubt the device really needs 2A, that sounds more like the definition of a generic phone charger than functional requirement. But yeah POE or simply a regular extension cord where you plug in a short cable at the end would be a safe bet.

I've bit the bullet and ordered a POE to USB adapter, which seems like the best plan. I'd rather that then running another 240v cable through the roof anyway.
