Eli5: does it matter if i power off a device from its power source or use the switch button (devices with on/off switches, not TV)

Hello eli5, i tried looking online and in eli5 but couldnt find anything specific to my question

I was wondering if is there any damage to a device (such as routers) if i power it off from the main power outlet instead of pressing the on/off button via device? I have read that TV has a standby mode thus it helps not to just power off via power outlet. It make sense for devices such as PCs/console as they would need to power down

Wondering if this is the same for devices without standby/power down functions

If the device’s on off switch is a big meaty clicky switch that is switching mains, then no there’s no functional difference.

If on the other hand it’s like a power switch on the back of a NAS say, that isn’t a straight up pull the plug power switch. What that’ll do is tell the device to power down, which might involve various housekeeping tasks, stopping hard drives, all that kinda thing before finally switching off.

So the answer, as is often the way with this kinda thing is “It depends.”

Some devices, even devices that have soft off switches (which is what that NAS example is) won’t mind being pulled from the wall direct. A TV is a decent example, most TVs won’t care if you just unplug them.

If you did that to a PC or NAS while it was writing files for example, then you’d cause data loss. If nothing was happening and the machine was idle it’d (probably) do no harm.
