Gallagher M800 Energizer

Reliable All-Season Power for Small to Medium Pastures — Gallagher M800 Energizer

The Gallagher M800 is a customer favorite for good reason — it delivers more punch than entry-level energizers with 8 stored joules and 4.9 output joules, powering up to 90 miles of clean fence across up to 520 acres. It's the dependable all-season workhorse for operations that need reliable livestock control without stepping up to a commercial-grade unit.

Built with a tough outer casing, integrated lightning protection, and simple plug-and-play installation, the M800 is designed to be set up and forgotten — running season after season without fuss.
