You switch when something is not working and you grow tired of that thing not working. If you never encounter that, you are good.

Someone should rename the gens. I never know what people are refering to with the arbitrary names. Maybe gen a, b and c would work.

Cause it takes time and effort. Most people just pay someone else to read the manual.

It’s part of the standard. It’s slightly different for each USB verision. USB 2.0 starts at 100mA at 5V and the device can negotiate up to 500mA, if the host can deliver.

USB is intelligent. The device should draw as much current as it asks for. If the device is not detecting any host to do any data transfer with, then it is probably idling at lowest unit power load. I would bet it’s not bad for it in any way. As long as that power brick lives up to the standard.

Uncanny resemblance.

Can never make too much pasta. Better too much than too little. Can always throw the leftovers in the fridge and microwave it the day after or make a lunch box. Of course, if you are struggling with overeating, then idk. Make to little maybe.
