For the longest time Ryanair actually gave me more money than I spent with them on tickets.
These hand held scanners have been a thing for over 10 years, way before the current iteration of self checkout stations. They continue to exist side by side with self checkout stations at supermarkets mainly.
It also should be noted that I have not seen a single self checkout station in the Netherlands that puts restrictions on how you scan your items. It doesn't care about weight and in what order you scan and put items into your bag or if you just keep holding the items, and I never have any issues with this system breaking or complaining about anything.
I would say it flattens out pretty quickly and doesn't keep going linearly. This probably has to do with the fact that the device was designed to be powered from 12V so the supporting components of the power supply would have been chosen to maximize efficiency around that input voltage.
EDIT: I was curious and had a WRT54G v2.2 laying around (unlike the 1.0 used by OP), which results in this graph: https://i.imgur.com/CBNTtRI.png The lower power usage can probably be explained by my later revision having less LEDs and more integrated chips instead of several discrete ones.
I also find his testing methodology inconsistent. In some cases he takes manufacturer specs at face value without actually verifying them, in others he goes out of his way to comprehensively measure things that don’t matter much (to me anyways), while skipping things that seem genuinely important (self-discharge of jump starter packs for example).
That said, he's doing this with his own time and money, and makes it available for free to anyone. A lot of this also comes down to personal preference in what you value in a test.
