Features:

  • Easy to mount
  • Solar-powered
  • Easy to use

This electric fence charger can only cover up to 2 miles, but for the majority of people, this should be more than enough. It is a little on the cheaper side of things, so it will be ideal for those who do not have a high usage requirement, and it is ideal for keeping some of the smaller cattle that a person has in their paddock.
This is an electric fence charger that was clearly built for outdoor use. While it is unlikely to withstand the most torrential rains, the terminals have been positioned so that light to moderate rainfall can hardly affect it.
However, the performance is low. It is only capable of emitting 0.07 joules. This means that it is more suitable for well-behaved animals that are unlikely to try to escape. It will not keep predators away.

Features:

  • Easy to mount
  • Solar powered
  • Easy to use

Features:

  • 15 joules shock action
  • Fuseless design means easier maintenance

Zareba provides an electric fence energizer that offers outstanding coverage for big farms, and the EAC200MZ offers it in loads, with a 200-mile operating distance. It provides 4 x the operating distance of the closest competitor, and this electric fence energizer is equally efficient. The Zareba offers great joules of energy, and at 15 joules this energizer is capable of putting sires and bulls on the field. Neither wild boar nor bear is likely to get into a fight with the fence.
Nevertheless, this charger for electric fences does not come at a low price and is among the priciest offers on the market. You also have to take into account the mounting of this energizer because it is among the largest and biggest on this list and it is not water-resistant. Therefore, you will need to construct a special case to keep the charger safe from the atmospheric conditions.

Features:

  • 15 joules shock action
  • Fuseless design means easier maintenance
  • 200 miles of coverage that is the best in its class

Energizer for Electric Fence - Best Choice

Electric Fence Controller

How to wire an electric fence energizer?

Your Electric Fence Charger must be mounted in a clean, safe place that is protected from humidity and solar radiation (excluding solar-powered chargers). The charger must be suitable for a ground spike system that is isolated from the grounding of a building or another barn facility. When an AC charger is used, it must be placed as close as possible to the current supply and the electric fence. Fasten the fence charger to a pole or a wall using a screw or nail to attach it through the suspension hole in the casing of the charger.

What is the amperage of an electric fence energizer?

The tension sent across the cables is strong, yet the current or gain (amps) are very weak. A 220-volt shock will be just as painful as a 10,000-volt shock when the current or gain (amps) is equal. The amperes are the thing with the killing power. Electric fence power generators produce a high-tension voltage (about 8,000 volts), yet very little current or amplification (about 120 milliamperes). This is equivalent to 120 thousandths of an ampere. It would not be enough to knock out even a squirrel.

Things to consider when buying a good fence energizer


    Joule and range

This is the amount of energy that the charger delivers. Different models have a different Joule power, so it is important to be aware first of all how much electric fence needs to be charged and how big the animals are that you want to trap or scare off with it. If you have a larger pasture, then something with more joules and a greater range would be required, but at the same time you need to make sure that the power is appropriate for the size and level of the animals that will potentially shock them, you don’t want anything that could potentially kill the animals. With a special electric fence tester, you can check the performance of your fence to make sure it is working properly.

    Power Source

There are 3 types of energizers you can buy – AC, DC, and solar-powered. All 3 use a different power source to power them, AC models need to be connected to a power source, DC to a battery and solar models use a panel to generate energy from light.

    Weatherproof

Since we are playing with electricity and nature here, the last thing you want to do is buy a charger that is not waterproof and leave it in the rain. Normally AC powered devices are not waterproof because they are usually connected to a power source, and along with DC models they may need to be built something around them to protect them from the elements. Most solar-powered electric fence chargers you will find are waterproof and designed to withstand harsh weather, simply because they need to be outdoors to absorb light that they can convert into energy.

    Warranty and returns

Chargers for fences can be expensive, especially if you have a large pasture or a large area that requires more than one model to power the electric fence. Most of the devices you will find on the market are covered by good warranties and return policies. All the manufacturers listed in this report offer a warranty, with some offering a much larger warranty than others. Most manufacturers in this industry are responsive and fairly easy to deal with when it comes to returning a unit or having it repaired.

What conditions can the charger handle?

This is also important to consider. For example, there are some fence chargers on the market that are not capable of controlling weeds so effectively and should probably not be used in areas that are not regularly maintained.
In general, the more power the charger has, the better it is able to control weeds.
If a person is in an area with heavy rainfall, a sealed unit is much better suited. This ensures that the Electric Fence Charger for livestock can last as long as possible.

How much voltage does the charger have?

The more voltage, the more power the charger can pump out. Generally speaking, if a person wants to keep horses, cattle, and other large animals in their paddock, the charger closer to 12 volts is probably a safer choice.
It must also be checked if the charger comes complete with the battery. If this is not the case, a separate battery must be purchased, which can increase costs.

How is the charger supplied with the power?

Solar energy is always best for a charger for electric fences. Maintenance is very low, whereas the battery can supply much more energy and you don’t have to worry about sunlight causing problems with the charger, although it does of course require a little more maintenance.

Last statement

This is our top chargers for electric fences to keep your cattle and horses in check on your pasture or land. Just remember to consider the mileage of your electric fence and what power is required for the animals you want to keep locked up or deter. Fencing livestock is not just about containment, you also need to get your energy balance in order and use something that won’t harm your horses or cattle, but at the same time is strong enough to deter unwanted animals such as bears, coyotes, deer, and pigs. Electric fences are no joke and can be dangerous. Take your safety and that of your animals seriously and buy the right energizer for your facility.

Electric fence charger for cattle - FAQ

⁉️ What voltage should my electric fence charger have?

The voltage does not play too big a role. It is rather the number of joules that are output along the length of the fence. However, it is not recommended to choose a battery with less than 6 volts, 12 volts being more ideal. The lower the voltage, the less fence can be covered and the lower the shock, which means it can be difficult to control the cattle.

⁉️ What does a low impedance fence charger mean?

Low impedance means that the fence emits a high current (important for covering the length of the fence) but a low voltage, which means that anything that comes in contact with the fence will only receive a light electric shock.

⁉️ How to connect the charger for the electric fence?

In most cases, terminals are located on the charger. It is simply a matter of running wires up to the charger and then attaching them to the steel wire of the fence. The fence can then be tested with a voltmeter to ensure that it is actually electrified. The fence can also be touched. The shock will be very mild, although this is of course not recommended.

⁉️ How the charger for the electric fence works?

They simply work. The current simply flows along the fence like an electric circuit. So it’s like any kind of wire on the market is supplied with electricity.

⁉️ How long do chargers for electric fences work?

It depends. The electric fence chargers on this list can last years. The batteries often last a few weeks before they need recharging. They do not use much power at all.
