Tecomec and Oregon used to sell 12V, bar mounted, chain grinders. Northern Tool (and other?) companies also offered some. I have not seen these for a while.
Some milling guys said that they liked these, because of the time it takes to remove / mount a chain on a guide bar, that is mounted in an Alaskan mill (or similar).
Saw this yesterday (have not tried it). Uses a proprietary battery, and mounts to the guide bar with 3, rare earth magnets.
