How We Chose the Best and What to Look For 

Cattles behind electric fence
Electric fences can either be off-grid or grid-tied depending on the situation.

Knowing what separates the different types of fence chargers will help you narrow down the options. Here are a few factors that we considered when choosing the best. 

Charger Terminology

Low Impedance 

Understanding low impedance is the key factor affecting your choice.

Low impedance simply means the flow of current through the wire brings less resistance overall, resulting in more power flowing through the wire with less heat generated

Solid State

Solid-state fence chargers offer a moderate current that does not require a long time to maintain. This charger is best suited for short-haired animals and/or small pets

Continuous Output 

A continuous output charger produces a stable charge, meaning electricity will be supplied continuously and uninterrupted during operation. This charger is ideal for dairy stalls and smaller paddocks

Types of Fence Charger

Plug-in (AC) Powered 

Plug-in chargers are directly powered chargers that require you to connect the charger to a power supply or grid.

You can use this type of charger to plug into several walls or use an extension cable. In a remote place or areas away from the power source, you should seal the path of the electric fence energizer for safety. 

DC (Battery) Powered

The DC charger uses batteries to power it. This can make it easier to operate, and helps you avoid problems like finding cables, or sealing off cable paths. 

The only thing to remember here is batteries need to be charged in a timely manner to ensure consistent energy coverage.

You could even buy an extra set of batteries and trade them out whenever one set needs to be charged. 

Battery chargers typically do not come with electric barrier chargers. While some are rechargeable, others just need to be replaced when their power has been depleted. 


By far the most environmentally conscious choice, solar-powered electric fences need to be charged, but the charger is connected to solar panels.

When the sun is present, the battery absorbs it, turns into an electric current, and then transmits it to the charger. 

It is also important to note that chargers that run on solar power can operate for 2 weeks without sunlight. They are usually fairly easy to use, light, durable, and easy to move if you need to. 

The acid batteries of these chargers have the longest lifespan, at nearly 1,000 charging days

Size and Power of Charger

The best tip for choosing a charger is to choose one that has certain parameters and numbers for your property that will provide you with an efficient charger. 

Instead of relying on what the specs are according to the manufacturer, we paid more attention to specific needs.

Manufacturers provide those numbers based on ideal conditions, but as you know, that’s not always the case. 


Volt is an SI unit of electromotive force that can be defined as the difference that will potentially be carried with 1 ampere of current against one-ohm resistance.

Volts can help you predict at what force your cattle could be endangered because, for any kind of cattle fencing, the maximum amount of volt allowed is 7,000


Miles is a parameter that involves the ability to charge an electric fence successfully to handle a fence of a certain length. 

The flow of current is secured for the fence length indicated, but if the fence length exceeds permissible standards, the efficiency of the current is compromised. 


Each fence will have a certain degree of shock power, and an efficient charger not only keeps cattle inside the fence but also protects them from outside predators. A joule refers to the power required to shock. 

You can refer to the following list for minimum requirements: 

  • Cattle and horses: 3-5 joules
  • Deer and pests: medium power
  • Predators: 3-8 joules
  • Boar: a large shock of power
  • Bear: high power


Most fences come with user guide manuals, and make it easy to follow instructions. However, it’s good to keep some factors in mind. If you choose the AC charger, you must connect it to a power of 110 volts.

Chargers might need to be protected from weather factors so make sure to put a protective cover around your charger if it’s not waterproof. 

Always, always, always use insulated ground wire for safety. Fence chargers should always have a separate ground rod system.

This ensures that it remains separate from the ground rods that your home relies on. Fix the charger covers with screws or nails to limit outside impact exposure.

With all of that said, let’s hop into our reviews of the best electric fence chargers for cattle!

What to Consider When Choosing the Best Charger

electric fence
Electric fences can vary in how many wires are used, the voltage, and how it’s powered.

Number of Fence Wire Strands

For multi-wire fences, divide your charger distance rating by the number of wire strands, and then choose a charger with a mileage rating that meets your needs. 

It’s important to note that when adding additional wires, you should increase your electricity demand, as well. 

Amount of Weeds 

It is vital to regularly treat the weeds near your fence, because when the weeds touch the fence, it will draw electricity, and make the fence more energy-consuming.

Though, it’s unlikely to catch fire, but it is not impossible, however.

If your fence has a lot of weeds growing around, a low impedance charger would be best to ensure the electrical energy of the fence is always maintained at a high and stable level. 

Area to Enclose 

The strength of your charger ultimately depends on the length of your fence to ensure consistent electrical capacity. 

The electric fence energizer will list a mileage rating, but it is important to note that this number does not account for external environmental factors, such as weeds. 

Types of Animal Controlled

Larger cows and bulls will require a greater shock than smaller breeds. Similarly, more aggressive cows will need a stronger fence charger.

Electric fences are safe to use for cattle and help to protect them from escaping the pasture and getting into potential danger.

1. What Size Fence Charger Do I Need for Cattle?

While manufacturers will push their competitive numbers, it’s important to remember that the strength of your charger should really depend on how long the wires are. 

First, determine how many miles of fence lines you have. It’s important to count all of the strands of wire that go around the fence.

For example, 5 strands of wire across 5 miles of the fence are 25 miles in length, requiring a stronger charger. 

Generally, 8-20 miles/joule is what is most available today, but again, this number is not practical for normal conditions.

If your fence has grass, weeds, tree branches surrounding, rain or snowfall, you may only get 3-6 miles/joule. 

Many chargers also include their electric power by the number of acres, but don’t be confused by this since the length of fence lines will vary greatly on the different perimeters of your setting. 

2. How Many Volts is an Electric Fence for Cattle?

The suitable voltage range for cattle is 2,000 to 4,000. Gentle and quiet cattle like dairy cows can be kept with lower voltage, whereas more aggressive ones like bulls would require a more powerful charger.

3. What Fencing is Best for Cattle?

High tensile wire fencing is the most expensive, but provides results. This type of fence can bear over 1,000 pounds of pressure, without losing its shape.

It also requires fewer repairs than all fencing options. Hinged joint fencing provides the most cost-saving results and can also be used for horses and goats since they won’t get stuck in between the fence. 

However, it’s important to note that they won’t be as stable as other fences, and need frequent checks and maintenance. 

Barbed wire fencing may sound out-of-date, but they are still added at the top of the hinged joint, and high tensile fencing to help keep predators out. 

4. Will a Cattle Electric Fence Hurt a Dog? 

Electric power of 2,000-4,000 volts running through the fence will definitely hurt a dog.

Your dog may feel slight panic after touching the fence, but if this continues to happen more than one or two times, he may not want to go out to the yard anymore. 

It’s not recommended to use an electric fence made for cattle for dogs. There are other electric fence options you can use for your smaller animals.

5. Can cows sense electric fence? 

Cows can hear the electric hum of the charge going through an electric fence. And once trained, they will avoid the fence.

6. How many volts does it take to stop a bull? 

It is recommended to maintain 3,000 to 4,000 volts on a fence for bulls.

7. Is Thicker wire better for electric fence? 

Yes, thicker wire is better as the thicker the wire, the more electricity that will be able to be transmitted. The smaller the gauge number, the thicker the wire.

Honorable Mention 

1. Parmak Magnum Solar-Pak 12Considered for Best Low Impedance

This charger offers low impedance, and a 12-volt battery that reaches over 30 miles.

This model is weatherproof and portable for easy movements around the property. Some reviewers complain of circuit failure, but this model does offer a warranty.

Whatever charger you go with, it’s important to take your needs, property size, and resources into consideration!
