How are you measuring that? I've been scouring the web for low-idle-power builds and 3.5 watts is far below the best builds I've found (assuming that 3.5 watts is measured at-the-wall).

The futro S740, popular with selfhosters in Germany, gets similar wattage for people [0]. On a slightly older CPU (J4105).

I can't measure values below 10W myself, but with 2 SSDs and 8GB RAM it never goes above that value, even under full load.

I've measured about 5w from the wall with Pentium J5005 based Dell thin client which has a tiny fan, one SSD, two RAM modules. No idea how N100 compares to J5005.

N100 runs slightly hotter, I've seen it more like 6-8W

Just a cheap measurement adapter you plug between the wall and cable.

The nice thing about n100 Is its ability to disable the iGPU in the bios, saving you a little bit of power. But you have to reset the bios on the board to regain any output if you might need it later.

Sounds interesting, could you please share brand and model? Also, do you know how many SSDs/HDDs you can put inside? Could be a good replacement to have a low power NAS.

Unless I'm running on battery, that's a pretty abstract win to me in the US. My i5-6500t's 10W for all 8760 hours of the year is 87kWh; less would be nice but my power bill is already under $10/year at that rate.

It is great that something on par is so affordable & even lower power though! And what I bought was a value because it was used, where-as now you can buy new. It's felt like the atom lineup was kind of slow rolling things & there hasnt been much availability for cheap AMD systems. These low price low power e-cores systems have really changed the game, have expanded the value proposition a lot versus the used-x86 mini PC or io limited ARM market's long stalemate.
