Best Electric Fence Chargers – Buyer’s Guide

Gardening, crop field, and pastures are occupations where people work on that for good results like a good crop from the field, flowers, and other items from the garden or livestock animal keeping. Well, all these things need to keep safe from a natural calamity as well as from unwanted animals like other domestic animals, predators, etc. These create a threat to livestock and garden when there is no guard.

For this reason, you need serious protection for excellent control overall. An electric fence charger is the best option for keeping the livestock safe as well keep them alive from the different predators and carnivorous animals.

Choosing the best electric fence charger is quite a time-consuming job. When you think to put a fence on the field for the predators, you need to know about the livestock you want to save and how can you keep them with no risk. All animals do not have the same capability of absorbing shock.

So, before installing the fence, you must calculate and know the power, voltage rating, and current rating for the perfect fencing charger.

Electric Charger Terminology


 For an electric fence to be low-impedance means that it has a low resistance which makes more power to be passed through the wire.  These types of chargers are the best because bushes and weeds do decrease energy output when they crawl on the fence. Generally speaking, the more power energizer has or puts out the more likely it is to deal with weeds. Energy output is also decreased when it comes in contact with herds and livestock. When it comes to bigger animals such as horses and goats, it is advised to buy a high-impedance charger.

Continuous Output

This term simply means that there is an unbroken stable charge on the hot wires prior to pulsing charges. Recommended mostly for smaller padlocks and dairy stalls.


These types of electric fence chargers deliver a medium amperage of shock pulses at a reasonable period of time.  They are perfect for short hair animals and pets, and they also perform well with light weed existing conditions. 

Types of Fence Chargers

DC Powered

If you have an off-grid farm or a farm located in a rural area, this type of fence charger is the best you can invest in.  This DC or otherwise known as a battery-run fence is much simpler to use than AC chargers  because it draws or gets its power from a battery rather than being plugged into the wall.

This feature made it perfect to use in most remote places. However, since they are battery powered, they need to be recharged every now and then to keep the fence in function.

If you want to have a functional fence with electric protection, you can purchase a few DC batteries and change them over time while charging the ones that have been previously used.

Most users want to know how often do the batteries need to be charged and the answer depends mostly on how many times the device is grounded. This simply means that if weed is growing around the fence or the animals keep on touching the fence with their limbs scrubbing the ground and the fence, the battery of the electric fence would drain much faster than compared to when the fence is clear of any touch.

If your livestock is already trained to keep clear off the line, you will actually get a very long result. Regardless of how the livestock is being trained,  they are more likely to touch the fence during their training so consumers have to take into account that at these early stages of training, the battery of the electric fence would drain much faster.  With that said, it is also important that you check your battery from time to make sure your fence is constantly safe.

Usually, batteries are not included with electric fence chargers and some of them can be rejuvenated while others need to be totally replaced.

Best Electric Fence Chargers – Buyer’s Guide

AC Powered

These types of electric fence chargers are powered by an electric circuit connected to your electricity grid.  They can be plugged in sheds or your barn and an extension cord might as well be run from inside the house to your fence. 

AC chargers need to be plugged into an outlet for it to function and it needs to get regulated electricity to keep protecting your livestock. This makes this type of charger easy and comfortable to use but it would be useless in a remote location unless there is a power source that the energizer can be plugged into.

Solar Powered

From just the name, you can fully understand how these types of chargers work to gain their power. This is the type of charger you use when you don’t have a power grid because this charger draws its energy directly from the sun and is stored in a battery connected to it.

 The only difference between the solar-powered charger and the DC powered charger is that it has a solar panel.  This panel powers the charge and makes sure that it functions every time. With this type, you don’t need to purchase extra batteries because there is no need to swap. This makes solar-powered fence chargers the best for rural and remote areas as well as strip grazing systems.  Solar-powered chargers are light in weight and they are very easy to carry around.  The only disadvantage this model carries is that it won’t function if there is no sunlight.

Acid batteries are normally used in conjunction with solar-powered chargers lasting approximately 1000 days or better yet 3 years of constant charging. Most experts recommend that users get a backup in case the battery develops a fault.

Key Features and My Experience

Taylor Fence makes cyclops Brute in the USA, and it is the strongest fencing recommended by the company as per the electric fence charger review. The solar and battery-powered circuit operates the fencing. You can cover 100 acres’ area with this charger, and fencing wire can be 8 miles long for good protection over the animals.

The facing gives a wide pulse to the animal which keeps them together within the fencing area.  The charger gives 8-joule output which is high to protect the livestock in a manner . Cyclops Brute charger is best for lightning protection.

Sometimes, if you are looking for a fence that gives off more shock than usual, the Cyclops Brute charger is the best option out there. A normal electric fence can give off quick sharp shocks but if you want to roast anyone that comes near your livestock, you are going to need a lot of power which the Cyclops Brute charger carries. But all this power does not come very cheap.  The Cyclops Brute charger is one of the most expensive electric fence chargers on this list. This charger is designed in an old-school style and it still uses a fuse to power itself. 

Johnny Hunt

Looking at the Cyclops Brute charger, you will find out that it is the coolest and it packs more power than any other electric fence charger on the list. This product is best for people who really want to protect their livestock from theft as well as lightning protection. It has a 30 miles coverage which is spacious enough to handle a few animals. It can produce outputs from 8 to 32 joules which makes it very powerful and good for bigger livestock. However, since it runs on a fuse, it needs to be constantly maintained and repaired and this unit doesn’t run on GFCI compliant circuit.

  • Parts are available everywhere.
  • Strongest lightning protection system.
  • Good output power with 8 joules.
  • Pricing is higher than usual.
  • Wiring can’t increase due to a power limitation.

Patriot PMX120 1.2 Joule review

5. Patriot PMX120 1.2 Joule

  • Type: AC
  • Miles: 30
  • Battery: not included
  • Joules: 1.2-1.7
Check Price on Amazon

Key Features and My Experience

The PMX120 is one of the best electric fence chargers that are available on the market. With a positive impression and review towards this product, you can tell it is the ideal solution for restraining a few numbers of animals on your farm. The Patriot brand is one that isn’t American and its products aren’t made in the United States either. This brand comes from New Zealand, a country that is well known for livestock keeping and export. This means that all the necessary functions that you want from an electric fence charger are already in place with the PMX120.  This electric fence charger stands out in so many ways. One is that it is the only electric fence on this list that can be powered in three ways.  You can power it using just a solar array system, you can plug it directly to an alternating current or hook it up to a 12v direct current from a battery.

This setup allows you to choose based on your requirements. You can choose an AC outlet on your fence near your home. However, if the fence is situated in a remote location, the best means of power is through a solar setup. If the case may be that where the fence is put up doesn’t receive enough sunlight, you can set up a DC connection to back it up.  Although it is very easy to power up this electric fence charger, it isn’t the most affordable unit on the market. This is simply because it doesn’t come with all the secondary components needed to get it working.  You will need to purchase a solar system to get it powered up with solar, the same must be done with the battery unit and the AC adaptor for an AC outlet.

Johnny Hunt

My Overall Impression

The PMX120 has unique features that make it different than the other types of electric fence chargers. It is very convenient to set up and it can be powered in three different simple ways. Although it is very costly to set up, it is still a great product that is worth trying out.

  • It is easy to install and lightweight.
  • It is ideal for gardens and farms.
  • It features a durable sealed waterproof case with an indicator light.
  • It comes with a two-year warranty which would also cover lightning damages.
  • It has no on/off switch.
  • Nondurable product.

Fi-Shock EAC is made in the USA, and it delivers three years warranty with damage by the lightning fault.

The Fi-Shock EAC 100M-FS works in wet weed or bush conditions and it does a really good job in controlling giving off non-lethal shocks to the livestock while driving back thieves and predators.  The Fi-Shock EAC 100M-FS is one of the easiest fences to use due to its operational features but this comes with a very huge price.  Although it is not the best electric fence out there, it still carries out its job and the money is worth the features.

Johnny Hunt

My Overall Impression

I’ve noticed that the Fi-Shock EAC 100M-FS is best suited for all weather conditions, especially when it comes to stormy weather. The electric fence charger provides enough energy output which shocks and keeps animals safe but it is non-lethal and it doesn’t cause serious harm to livestock. I like that this charger uses digital timing and a useless design. The only downside to this product is the cost and also the installation process. Larger units have much more difficulty in installation.

  • Suitable for all weather conditions.
  • Storm protection for effective guarding.
  • Digital timing with the fuseless design.
  • The output voltage load is near about 12400 volts.
  • The 6-joule output is good.
  • High-cost fencing charger.
  • The large unit creates difficulty in installation.

This electric fence charger is a versatile one meaning you can use it on wires like poly tape, poly rope, high tensile wires, and poly wires. I totally recommend this product.

  • The 2-joule output is much more profitable.
  • Fuseless design for the fence.
  • Digital timing with indicator light
  • This charger is expensive.
  • Difficult to install.
  • The charger is a little bit noisy.

Key Features and My Experience

This electric fence charger from Red Snap’r controls all types of pets, nuisance pests, predators, livestock, and even poultry. If you have a limited budget and you want to contain small-sized animals, this is the best choice for an electric fence charger. It can be used in any type of fence which may include high tensile, poly tape, and poly wire.  This product is manufactured and designed to work efficiently along heavy weeded fences while also maintaining maximum potential throughout the fence.  With a 4V battery, this electric fence charger can power fences that measure about 25 miles long and it produces an output of about 1 joule.

Low impedance electric fence chargers possess low internal resistance, this allows an increased amount of joules over the fence line. This means that the current cannot be stopped by weed or any other light obstruction to simply keep the fence hot.

The EAC24M-RS low impedance fence charger delivers a highly effective but safe high voltage shock with digital timing. However, this gives off effective shocks, it is also ideal for bigger animals like horses or cattle but it is intended to serve you well on keeping smaller animals on their toes.  The only thing I didn’t like about this electric fence charger is the mounting mechanism. The mounting holes are located on top which makes a cinch job extreme.  Other features that come with this electric fence charger are 115 volts, 60 cycles, useless design, pulsed output, and digital timing. To add to that, this electric fence from snapper is UL listed and it is durable for a long period of time. The company also gave users a 2-years warranty for guarantee. It also features an indicator light that shows users whether the device is working or not.

Johnny Hunt

My Overall Impression

This amazing product from Red Snap’r is an ideal electric charger fence each livestock keeper and farmers need for their farms. It keeps away predators and keeps livestock, making it a safe environment to cater to them. With over 60 years of experience in electric fence engineering and design, you can say their products are easy to control and they can be used on any type of fence in any type of vegetation.

  • It comes with a 2-year warranty which would also cover lightning damages.
  • It is waterproof and resistant to harsh weather.
  • It is made in the United States.

  • Joules: .024
Check Price on Amazon

Key Features and My Experience

Most times, users just want a basic electric charger for their fence. This is mostly due to the fact that they live off-grid or they have no connection to the power grid. Even if they are situated in a place where sunlight cannot get to them totally, it can still be used under these circumstances. All you just need to do is to easily plug the clip into your electric fence. This product is DC powered so you have to get a 12v battery if you don’t have one. The charger makes use of two of these types of batteries and you need to replace them at least monthly. If you have a power grid-connected, you can make use of rechargeable batteries.

With the Powerfids B2D, please avoid using car batteries. People result making use of old car batteries that aren’t functional in cars anymore which is not ideal for most electric fences.

The reason is that car batteries release short, spaced, high-burst pulses which are not recommended for electric fences. They can short circuit your product as well as the electric fence itself. Instead of making use of car batteries, you can just get two D-Cell alkaline batteries and backup batteries because the product doesn’t come with any at all.

 This product releases energy of up to 0.04 joules and it also has a ground clip and a fence clip. It is compact and lightweight in design and it only weighs about 1.6 pounds making it one of the most portable devices on this list.  During set up, just slide the clip along the fence moving it to your required position. Make sure you disconnect the device as you do so.

Johnny Hunt

My Overall Impression

If you need an electric fence that runs on a purely alkaline battery, this is the best candidate for you. No power source, no problem. Just make sure you have an extra 12v battery lying around somewhere.

  • It uses alkaline batteries as a primary source of power.
  • Rechargeable batteries can be used.
  • It is compact and lightweight in design.
  • It is affordable.
  • It is suitable for only small farms.
  • The battery cover is not easy to put back once you take it off.

This is a very important feature in the electric fence charger review. It depends upon the usage of the electric fence charger and the power required for the shock. You must install a good meter for controlling the power and its impact on the pastures.  For chickens and dogs, a high-power charger will damage them whereas low powered charger is useless for big-sized animals.  The requirement is given.

Cattle and horse

 If you want to make a fence for domestic animals like cattle, horses mostly for females, it requires little power as joule output.  These animals can be controlled with a little bit of shock, and they are weak enough to stay within the limit. For these kinds of animals, you need 3 to 8-joule output for control.

Deers and Pests

Imagine you have a small garden and you are keeping away  animals like deer or pest . They can run in the place and ruin the field within a night. So, you have to keep them away in their area. Herbivorous animals are more reticent than others. So, you must install fencing with medium power that can push them from your garden like the place.


These animals are dangerous for any domestic livestock.  They can damage the livestock you want to keep safe . For example, you have a poultry farm. Coyotes and foxes are dangerous for the chickens. If you want to keep them away from your site, you have to put a 3-8 joule charger system that can deliver enough shock to those predators.


This animal is very much notorious and tenacious that it is hard to control. It runs all the place with no restrictions and breaks low-powered and medium fences. Boars require a large shock to keep them controlled.


Bears are animals with a thick fatty skin layer. They feel nothing when the shock level is medium, and they can do anything when they get the smell of food. So, you need a higher power punch of shock to keep them away.


Generally, there is a walkthrough handbook that comes with each fencer charger. Some other components also come with their reference books which will also aid in the installation of the various parts. However, it is good to know what you will be getting into, and here are the steps you can follow:

When installing your charger should be:

  • It should be near a source of 110 volts if you selected the AC type of charger. If not, ignore this step.
  • It should be very much protected from weather conditions except solar-powered chargers.  They should be kept inside to protect them from humidity or outside in an enclosed way. If it’s located in an area that is prone to constant rainfall, installing a sealed unit is the best option.  This would make sure that the electric fence charger lasts as long as possible.
  • Users should have a functioning ground rod system. This will be kept apart from other grounding rods used by your home.

If these precautions have been taken into accounting, mount the charger off the ground with a nail through the hanger hole in the casing. Get an insulated wire to connect the ground wire to the ground rods and terminal. The hookup wire should be 20,000 volts and above so you can be able to unify the fence terminal to the fence wire.

How to Choose Right Type of Fence Charger


How to Test Electric Fence Charger?
Start by touching the positive terminal of the fence tester to a part of the electric fence wire with the charger turned on. Also, stick the other grounding terminal to the ground. Get the readings on the fence tester (some come with volts, others come with a glowing light that increases when the current is stronger and vice versa otherwise. Check the charger by consistently touching the positive terminals and the earthing to the corresponding terminals located on the charger. If there is no current coming out of the charger, this is the main cause of the problem. You need to check if the charger is being plugged in well or if the fuse of the charger has burnt. If it is unrepairable, consider getting a new one.
How to Wire an Electric Fence Charger?
To wire an electric fence charger, it is important to start first by deciding where to place the charger. When that is done, install and wrap around at least two feet of ground wire on a steel rod and also attach one end of the wire to the electric fence charger’s ground screw. Next, get at least two feet of wire and connect the charger to the fence wire. Connect one end to the output screw and connect the other end to the electric fence wire. Next, connect the charger to a power source and test the electric fence charger.
What is a Low Impedance Fence Charger?
The output from these type of chargers is medium to high voltage but at much greater currents. A low impedance fence charger has a large reserve of currents are they are able to charge fences that are really long or overgrown by vegetation.
How to Fix a Fence Charger?
Check the fence charger with a tester so you won’t waste money purchasing a new one. Also, check around the first if there is a leak or any short circuit. Unplug the charger and check if any of the fuses have blown, if that is the case, then changing the fuse is the best option. Also, consider changing the energizer. If you have tried all these options and it doesn’t work out, consider taking it to a professional who can work on it.
How to Ground an Electric Fence Charger?
Install the fence wire correctly following step by step instructions on how to. Position your electric fence charger in a sheltered location. It might not be affected by low temperature but it will be destroyed by water. Get a grounding steel rod which is about 4 feet long and drive about 3 ft into the ground leaving 1 foot or a few inches above the ground. Next, connect the ground wire, this is mostly made up of an 8 or 6 gauge copper wire. Install the mounting bracket to the rod and insert one end of your ground wire into the connection point and tighten the screw. Insert the other end of the ground wire in the mounting bracket on the charger and also tighten the screws as well. Check the fence for faults and then correct if any.


The fence electric charger review is there to help. The fence charger is required for controlling the animals, whether to keep them safe or keep them away from your place.  Choosing the right and appropriate fence charger according to your need and ensuring it is the best fence for controlling the livestock and protecting them.  You must think about the power source available in that place of installation.
