The N100 is such a little powerhouse and I’m sad they haven’t managed to produce anything better. All of the “upgrades” are either just not enough of an upgrade for the money, it just more power hungry.
It’s the other way around. 0.1 kWh means 0.1 kW times 1 h. So if your device draws 0.1 kW (100 W) of power for an hour, it consumes 0.1 kWh of energy. If your device factory draws 360 000 W for a second, it consumes the same amount of 0.1 kWh of energy.
It does not yet make sense to me. It just feels wrong. I understand that you may normalize 4W in 15 minutes to 16Wh because it would use 16W per hour if it would run that long.
Why can’t you simply assume that I mean 1kWh per hour when I say 1kWh? And not 1kWh per 15 minutes.
A watt is 1 Joule per Second (1 J/s). E.g. Every second, your device draws 1 Joule of energy. This energy over time is called “Power” and is a rate of energy transfer.
A watt-hour is (1 J/s) * (1 hr)
This can be rewritten as (3600 J/hr) * (1 hr). The “per hour” and “hour” cancel themselves out which makes 1 watt-hour equal to 3600 Joules.
kWh is a unit of power consumed. It doesn’t say anything about time and you can’t assume any time period. That wouldn’t make any sense. If you want to say how much power a device consumes, just state how many watts (W) it draws.
Do you mean 0.1kWh per hour, so 0.1kW or 100W?
My N100 server needs about 11W.

To my understanding 0.1kWh means 0.1 kW per hour.

1 kWh is 3,600 kJ or 3.6 MJ

Thanks!
0.1kWh per hour can be written as 0.1kWh/h, which is the same as 0.1kW.
Thanks. Hence, in the future I can say that it uses 0.1kW?
Yes. Or 100W.
If this was over an hour, yes. Though you’d typically state it as 100W ;)
