Product description

High‑Performance 3J Output
This fence energizer generates 3 joules of stored energy and delivers up to 12,000 volts with a one‑second pulse interval. It is rated to support a single conductor fence up to 15 miles long under typical conditions, while its low current draw keeps running costs down. The intermittent pulses are designed to deter and contain livestock without causing lasting injury.

Three‑Way Power Input with Status Display
The unit accepts AC mains, an external 12V DC battery and solar panel input (12V battery and solar panel sold separately). A built‑in power switch and a prominent LED indicator panel let you monitor input and output status at a glance, helping you spot faults or low battery/solar conditions quickly.

Rugged Weatherproof Housing
Encased in a durable, weather‑resistant shell with an IP‑rated protective design, the energizer withstands rain, snow and temperature extremes from −20°C to +60°C. The sturdy enclosure is made for outdoor mounting; for extended life you can place it inside an additional protective box or shed.

Uses and Coverage
Engineered for pastures, ranches, poultry yards, orchards and garden protection, this energizer helps prevent escapes and deters predators such as coyotes, foxes, raccoons, skunks and martens. It’s suitable for containing cattle, horses, goats, sheep, and for protecting poultry and crops from wild intruders.

What’s in the Box
The package includes: 1× Charger main unit, 1× Input‑output cable, 1× AC power adapter, 1× Connection lead, 1× User manual and 1× Mounting hook for wall or post installation. No specialized tools are required for setup; follow the manual for safe connection and grounding.

VerdictA robust fence energizer that combines strong 3J output and 12kV peak voltage with flexible power choices and weatherproof construction. It’s built to protect pastures, coops and orchards across long runs while using minimal energy. The clear LED readout and simple setup make it a practical pick for farms and remote properties that need dependable animal containment and wildlife deterrence.

Reviews

The Bird Guy 5/5

Clear LED readout

Plenty of punch and weatherproof build. The LED panel makes it easy to check both input and output levels. Rated for 15 miles, which is far beyond my actual fence.
Heather Stewart 5/5

Effective 3J shock for livestock and predators

Impressed with the 3J energy and 12kV peaks — cattle, horses and goats quickly learn the boundary, and predators steer clear. The pulse is strong enough to deter without causing harm.
Tamara Prater 5/5

Built to withstand harsh conditions

Installed outdoors and it’s held up through rain, cold nights and hot days with no loss of output. Operates reliably across the −20°C to +60°C range and covers my garden and pasture with minimal upkeep.
Taylor Gibson 5/5

Versatile power for remote pastures

Excellent for off‑grid locations — runs on mains, a 12V battery or tied to a solar array (battery/solar purchased separately). I hooked it to a lead‑acid battery and it keeps my remote livestock protected continuously while only drawing a few watts. Setup was straightforward and performance has been steady around the clock.
