use anything that supplies a few amps of 12v power, get a better battery charger, use a train power transformer ... if you're only using one anode that might be why it's slow, doesn't take a lot of amps but large parts need more than one anode, the process is sorta 'line of sight'

and yeah, yer talkin tools, not trucks grin
