Swampseed, I have a Rapala but it is not cordless. It does work on 110 or 12 volts. It's not a powerful unit and I only use it if I'm away from 110 volt power. Even on the 110 volt adapter it doesn't provide much power. I know it not quite the same as the one you're asking about but I would think it's in the same class. I hope this helps and I hope someone with the same unit as you're asking about chimes in.
