Dewalt recently announced a new cordless electrical cable stapler, model DCN701, which they say is 2X as fast as manual hammer stapling (using a DCB203 2.0Ah battery stapling 12-2 Romex in 2×4 wood).
The new Dewalt cordless cable stapler is designed for fastening NM-B (Romex) type wires and cables, and can also be used for low voltage applications. There’s a proprietary guide that helps users drive staples safely and accurately over cables. Translation: there’s a staple guide that helps prevent users from stapling through cables.
