Yes, not converters or anything, just a battery and wires. I recently moved and my little zapper was thrown in a box and...destroyed. Thus, I wanted to upgrade and just bought a parazapper cca.
When I used my little zapper it helped but the problem continues to come back. I guess I was looking for something more powerful to maybe truly end the issue - better zapper, Miracle-Mineral-Supplement . Maybe that is wishful thinking and I need to resign myself to routine medicating/zapping the area.
