I am wondering, is it possible to use a 5.5 x 2.1 mm male plug inside a 5.5 x 2.5 mm jack for transferring 12 Vdc?
My thoughts are just that it may just be a tight fit on the inner conductor. It may also just not fit. I figured before spending money and waiting a few days to try it out, it was worth asking here.
My Use Case
I have an Intel NUC, which can be powered off 12 Vdc via a 5.5 mm x 2.5 mm jack:
The back panel DC connector is compatible with a 5.5 mm/OD (outer diameter) and 2.5 mm/ID (inner diameter) plug, where the inner contact is +12-19 (±10%) V DC and the shell is GND.
And it seems the 5.5 x 2.1 mm plugs are much more common, so I would like to use that.
