Zareba 10-Mile AC Fence Charger - 0.5 Joule Low-Impedance Energizer, 10,500V for Livestock

The Zareba 10 Mile AC Powered Low Impedance Fence Charger is an AC energizer that delivers 0.5 joule output and up to 10,500 volts to power electric fencing up to 10 miles in ideal conditions.

This low-impedance Zareba energizer is built for farms and rural properties that need dependable electric fence power across long runs. The unit runs on standard household AC, houses moisture-resistant electronics in a rugged cabinet, and includes a front-panel indicator light so you can check fence status quickly. Designed to work with high-tensile wire, polywire, or polytape, it provides the kind of steady output you need for cattle, horses, pigs, goats and general predator deterrence.

How much fence can this charger reliably power?

Under ideal, weed-free conditions the charger can energize up to 10 miles of fencing; when vegetation load increases, expect effective coverage to decrease. In heavy weed contact the unit still maintains useful effectiveness across multiple miles thanks to its low-impedance design.

• Up to 10 miles in ideal conditions (no weeds)
• Maintains performance across several miles with light vegetation
• Up to 2.5 miles effective in moderate weed conditions
• Continues to function under heavy weed contact where smaller units fail

Will this charger contain my cattle, horses, or goats?

The Zareba 0.5 joule output generates up to 10,500 volts—enough to provide a clear psychological barrier for most livestock when installed correctly. It’s suitable for containment of cattle, horses, pigs, and goats when paired with appropriate insulators, wire type, and grounding.

• 0.5 joules output for a noticeable, humane deterrent
• Works with high-tensile, polywire, and polytape fences
• Voltage and pulse rate suited for medium- to large-sized livestock
• Pair with proper grounding and fence layout for best results

How does the low-impedance design help in real-world conditions?

Low impedance means the energizer keeps delivering pulses even when the fence contacts weeds or brush, reducing power loss and improving reliability. That design minimizes the performance drop that typically occurs when vegetation touches the line, so the fence remains functional longer between maintenance cycles.

• Maintains pulse strength when vegetation contacts the wire
• Reduces false trips and power loss compared with high-impedance units
• Better for long runs where sporadic contact with weeds is likely
• Helps avoid frequent weed trimming along large perimeters

What installation and durability features should I expect?

The charger is AC-powered for consistent energy and is intended to be mounted under cover to maximize lifespan. A moisture-resistant internal layout and a heavy-duty cabinet protect the crucial electronics from harsh weather, while a built-in indicator light gives a quick visual check of fence status.

• AC-powered — plugs into standard household current
• Moisture-resistant components in a rugged housing
• Front-panel indicator light for quick fence checks
• Recommended to install under cover for longer service life

Who is this for: The Zareba 10 Mile AC Low Impedance Fence Charger fits farmers, ranchers and property owners who need a robust, long-run energizer that resists vegetation-related performance loss. Choose this unit if you manage multi-mile perimeter runs, use high-tensile or polywire systems, or want a made-in-the-USA energizer built for year-round outdoor conditions when mounted appropriately.
