> With the power supplies of this era, this pair of devices probably pumps 16w idle. Running 24/24 7/7, they probably consume as much as a small fridge as a whole. The LCA of the solution must be consterning as well, especially compared with few one dollard microcontrollers.

At the average cost of electric in the USA this amounts to under $2/month. Seems negligible to me?

For a device with so little functionality and non-critical functionality at that, I wouldn't call $24/year negligible. My whole home Ryzen router/server idles around there. Honestly I'd bet the fuse was missing because the last tenant was an engineer, investigated this thing themselves, found it a useless waste, and pulled it.
$2 is median daily wage for several countries. Negligible in US but not everywhere

I don't think places like that have folks in new construction with Ethernet and Android tablets in the wall. TFA uses GBP as the currency in the images.
Yes, but those countries also have different energy cost.
you must be fun at parties.
Still cheap, but the cost per KWH in UK is at least twice the average in the US.
Please send me 2$/month if you don't mind.
Sure no problem. Just power my 16w tablet in exchange. That's what this thread is about: A tiny cost for a tiny convenience.
