If you have an electric fence charger, you’ll be able to rest assured that predators will not eat your cows, sheep, or goats and that your pets will not escape. As long as your security fence is operational, you can protect your animals and property.

Zareba EAC50M-Z AC-Powered Electric Fence Charger

Zareba 50 Mile Fence Charger

Using the Zareba EAC50M-Z AC-Powered Electric Fence Charger, you can ensure the safety of your animals within the enclosure.

Powered by AC current, in this reliable 2-joule charger predators such as wolves and bears are shocked to halt their advance. The intense shock delivered by chargers will have predators fleeing for cover.

A wide variety of electric fences can be used with this product, including poly wires, poly-tapes, and high-tensile fences. With a low-impedance design, a perimeter fence can be driven up to 50 miles in weed-strewn conditions.

This rugged, weather-resistant charger, which is designed for rough weather conditions, protects the moisture-resistant internal components from damage. Color-coded controls and an indicator light are included on the charger.

Besides the 3-year coverage, Zareba guarantees lightning damage as well.

With an electric fence charger, you can set a distance of 25 miles, 75 miles, or 100 miles.

A Guide to Selecting the Best Electric Fence Charger

Power Source

The chargers for electric fences can be powered by electricity, batteries, or solar energy.


As your fence will remain powered, the Zareba Electric Fence Controller will use AC power to charge. It is as easy as plugging in the charger, and then you will have protection day and night.


Homesteaders living in remote areas may find it difficult to use a charger powered by AC power. In the case of living off the grid or not accessing an AC outlet, battery-operated or solar-powered chargers come in handy.

Batteries are a cost-effective and safer substitute for electricity.

In order for your fence to be powered, your batteries must be charged constantly.

Solar Power

Solar power is a cheap and clean option for powering fences around a smaller property. In order to capture and store heat from the sun, the panel must be properly positioned.

Chargers powered by batteries or solar power may not be effective for zapping large predators or fenced areas.


When buying an electric fence charger, the Joule rating is one of the most important factors to consider.

Smaller Properties

A charger with a low output of 0.1 or 0.10-joules is necessary when raising chickens or caring for baby goats on a property under 40 acres. Such low-energy shocks will have no adverse effect on your animals.

Larger Properties

You will need a 4.9 or 20-joule charger for a fence that is longer than 50 or 75 miles and that prevents predators such as wolves, bears, and wild dogs from entering.

However, these chargers are not ideal for chicken coops or pet enclosures despite their effectiveness in deterring larger predators. It is possible for small animals to be in danger from the joule output of a charger. Although the electric current may not kill them, it can seriously damage their hearts and nerves.

Fence Compatibility

Electric fence chargers must comply with the fence’s specifications.

Several types of chargers exist; some are designed for single-type fences while others can power polywire, rope, or polytape fences. Using fiberglass rods can protect you from electric shocks if you have a chicken wire fence made of galvanized wire.

Low Impedance Electric Fence Charger

Power loss can be caused by a variety of factors. Plants, trees, shrubs, and weeds that grow in the rain can be powered by the charger.

No matter how thick the brush or weeds are, low-impedance chargers are still capable of delivering a powerful shock.

Color-coded Terminals and Handy Features

There are usually two color-coded panels on electric fence chargers: red and green and red and black.

Parmak MARK8 electric fence chargers have an LCD indicator light as well as an LCD screen that displays voltage.

Another handy feature is an indicator of the battery’s power level.

FAQs On Zareba EAC50M-Z

How does a low impedance fence charger work?

An impedance-low fence charger means the cable has less resistance (or impedance) so more power can be delivered to the battery. The latest technology for controlling weeds on land is the low-impedance electric fence charger.

Is there a charger that is the strongest for electric fences?

Multi-wire fencing and 100 joules of power can be supplied by a single M10000i electric fence energizer.

What is the joule rating of a good electric fence?

The joule rating ranges from 1 to 20. A mile of fence per joule output, as permitted at the University of Missouri Forage Research Center, is sufficient for most situations. Maintain a fence line voltage of 3,000 volts at least to control most livestock.

Do electric fences work with two energizers?

Not at all. Electric energizers have components designed to match certain voltages and currents. Multiple energizers hooked up to one line will eventually destroy them.


All farm, ranch, and homestead owners should consider Zareba electric fence chargers. Power, efficiency, reliability, and simplicity of the Zareba charger make it an ideal charger for your electric fence. You and your livestock will feel at ease knowing that the fence is safe.
