Heavy Duty Battery RCA Cord

Some tattoo machines just aren't designed to run batteries, the Coffin C2 is a good example.  Lots of people out there run only batteries.  Ive been using this corded adapter to film videos for ever, so I thought maybe some of you folks could use it too.  This RCA Cord Battery Adapter will let you run any RCA battery with any RCA tattoo machine.  You can avoid the power supply and foot pedal, if your a battery only tattooer that wants to use a machine that is uncomfortable with a battery.  Hand made with thick 18g wire that is built to last.
