Durable Design - The charger's rugged, heavy-duty cabinet protects the circuitry from weather extremes

Powers up to 100 mile range

Works in heavy weed conditions

115 volt, 60 cycle; pulsed output (1-second intervals)

5 mile range in ideal conditions

High-power, low-cost

Extension power cord for easy placement

Controls most types of animals including horses, cows, pigs, goats, bull and exotic animals

Heavy weed conditions

115-volt, 60 cycle, pulsed output (1-second intervals), 4-joule output at 75-ohm

Suitable for electric fences (made of steel, aluminum or other conductive wire, rope, braid, tape, net) for containment of rabbit, poultry, pet, small-sized, short-haired livestock, or for keeping out rodents, small-sized wild animal, etc.

Powered fence distance subject to type and resistance of fence wires, number of fence wires, vegetation on fence, grounding and installation of fence system, animal intensity level, etc. Effectively powered fence distance around 1 mile / 4 acres in average (multi steel or aluminum wires, little vegetation), or up to 5 miles / 20 acres (single steel or aluminum wire, no vegetation). Heavy vegetation and poly fence products will reduce the overall power of the fence energizer.

Compact, sealed structure. Equipped with two terminals, ground (black) terminal for connecting to a separate ground rod, fence (red) terminal for connecting to the fence line. Indicator light flashes with pulse, showing working condition. Lightning protection included.

🐓Advanced Technology. The AgriOtter Energizer powers a fence line to keep pets and livestock corralled while preventing predators from accessing your land.

🐎Versatile Power Options. Can be used in 12V battery (Battery not include) or AC power (Regular 110v Outlet), providing convenient, versatile livestock control. Allow you use it for more than 2 weeks with a normal 12V battery.

🐂Easy Set Up. Large terminals. Mounted on the front of the energizer casing for convenience, these large terminals are easily adjusted. The slotted terminals make inserting wires and getting a good connection easy.
