Wiring and Battery Current Requirements for Electric Boat Winches
Question:
Can a motor load be connected to the adapter instead of inverter. Have boat electric winch and could connect to existing 2018 f150 -7way plug . Instead of installing new plug for winch. Thanks

Helpful Expert Reply:
An electric winch will draw a substantial amount of power from its battery, usually a lot more than the 25-amp rating for the Hopkins 12-Volt Power Inverter Adapter # HM11147650 that you referenced.
For instance, Dutton-Lainson StrongArm Electric Marine Winch # DL25215 draws as much as 70-amps. Bulldog Electric Winch # BDW15020 draws as much as 340-amps at full load. This is why winches should always be wired with a dedicated battery connection using a heavy-gauge winch installation kit like # DL24049.
