Adaptor for 12v to Mini USB?

[Glen]

I currently have a JAEWONCNC IROAD IONE-3300CH installed that uses, what looks to be, a 2.5mm male jack, for power.

I have a Mobius that I want to replace it with. rather than running a new power cable I would like to use the existing one used by the IROAD.

Is there an voltage stepdown adaptor that I can couple at the unit itself to go from 12v jack to 5v mini USB?

Ebay is full of 12V-USB adapters - but one with a 2.5mm jack input is asking a bit - you may have to cut the jackplug off and solder.
