In this post, I’ll walk you through the various aspects of an electric fence charger to help you make an informed buying decision.

Moreover, I’ll be throwing light on the important parameters that you need to consider while buying an electric fence charger.

Lastly, I would be responding to queries related to the electric fence chargers review in order to help you clear your doubts before you make a purchase.

In short, I’ve put all the information in one place that a newbie or a first-time buyer will need before making a purchase.

Does it sound good?

In the last couple of years, there has been a tremendous increase in the use of electric fences.

Nowadays, the use of an electric fence is not restricted to deterring animals from entering a particular area.

Electric fences are becoming popular among humans as well.

They are extensively used to enhance the security of sensitive areas such as military installations.

If you’re an old-school guy and still using barbed wire fencing, then the time has come to switch to an electric fence.

Some of the benefits of using an electric fence over barbed wire fencing are that the former cost less and takes less installation time.

In the context of agricultural fencing, they are a great fit.

If you’re a farmer from a region where the drought is very frequent, then definitely you should buy an electric fence because it will help you to manage the grazing area effectively as it can be uninstalled as well as re-installed quickly.

To cut a long story short, let’s discuss some of the best electric fence chargers that were made it to our list.

I often call the electric fence charger the heart of the electric fence.

The truth is that even though you bought a high-quality electric fence but failed to get a good charger for your fence, then you may have to face some problems related to the performance of the fence.

I hope now you’re clear about how important the electric fence charger is.

Trust me, without a good charger an electric fence is useless.

So, you may be wondering what do I mean when I say a good charger, right?

Don’t worry, by the end of this post, you’ll not ONLY be able to make an informed buying decision but also, you’ll be able to guide others to make a smart buying decision.

An electric fence charger is also called by the name energizer and fencer.

When it comes to buying an energizer, follow the thumb rule, Bigger is Better.

What I mean is try to purchase a fencer that has a bit more capacity than your usual requirements.

As we all know that the brush and the wet grass are the main culprits and consume a portion of power, so some extra power will help you to ensure that voltage is flowing through the wire without any disruption or hurdle.

Most of the time, my clients have shown high interest in knowing the correct voltage that one needs to pass through the wire during the summer as well as winter.

Well, if you’re a first-time buyer, then there is a high probability that you may not be aware of the fact that voltage passed during the summer through the fence wire varies significantly as compared to winter.

As a thumb rule, pass 2000 volts in summer and 4000 volts in winter through the wire of the electric fence for proper agricultural fencing.

If you’re installing an electric fence in the vicinity of a building, then flow a simple trick- install the fence at a place where rodents can’t damage the fence wire.

So, without any further ado, let’s have a quick look at all the electric fencer chargers that made it to our list.

Nothing wrong with it, as a buyer you’ll definitely want to settle for the best electric fence charger available on the market, right?

To be brutally honest, I’ll vouch for Parmak when it comes to features such as flexibility and weather-resistant, and the credit goes to the idiosyncratic design that allows Parmak to place the panel facing either direction.

On top of it, the customer care service of Parmak is definitely something to brag about.

Some of my clients do have to face situations wherein the switch buttons or something similar wasn’t operational and they asked the company to replace it at the earliest as it was under the guarantee period.

The feedback that I got from my clients was mind-boggling and they really appreciated the post-sale service.

The Parmak electric fence charger has a solar panel attached to its top.

Since it uses free solar energy, you don’t have to change the batteries very often, and if you’re wondering what will the outcome be if the weather is cold and cloudy, then let me tell you, this battery can perform extremely against all odds continuously for around 20 days in an ambiance equivalent to complete darkness.

However, you can expect an undisrupted service continuously for 20 days or so ONLY IF the battery is fully charged.

Here I would like to bring to your notice that the charger is capable of powering 25 miles of fencing only in ideal condition.

Well, you may be inquisitive about my definition of the ideal condition, right?

The ideal condition means the use of steel wires in the electric fence with no weeds touching the fence.

However, if you have got a poly fence line surrounded by weeds, then the charger is capable of covering only 12 miles of fencing.

You don’t need to learn any expertise to know whether this electric fence charger is working fine or NOT.

The manufacturer has introduced a “FENCE OK” light which will tell you about the fence status.

If the light is ON then it means the fence is up and running and vice-versa.

So, using this feature you can spot-check whether the power is flowing through your fence or not.

Definitely, a unique feature to boast about.

When it comes to the installation of the electric fence charger, people have lots of doubts and queries.

Let’s face it, failing to install the charger correctly can directly impact its performance adversely.

To deal with all the atrocities revolving around the installation process, the manufacturer has introduced the EAC25M-Z features.

Even though you’re a first-time buyer, you can exploit this feature to connect the fence line to the red terminal.

Don’t forget to connect the grounding line to the green knob.

Once you’ve done all the connections properly, you’re good to go.

How Does an Electric Fence Charger Work?

If you want your electric fence to prevent livestock from moving out, then a current needs to flow through the electric fence which is ONLY POSSIBLE if the circuit will be complete.

On the contrary, if something is ONLY CONNECTED to one side of the circuit then the current will NOT flow through it.

In short, an electric fence uses the concept of a “complete circuit” to work properly.

Using a charger, the pulse of electricity is flown through the electric fence leading to its electrification.

Still, the circuit isn’t complete.

So, to complete the circuit, the electricity pulse of opposite polarity is flown through the ground using a ground rod.

The ground rods are mostly made of metals for the efficient flow of current.

Now, we’ve electricity of opposite polarity flowing through the electric fence as well as the ground.

So, if a plant, animal, or even touches both the ground as well as the fence at the same time, the circuit will get completed resulting in a shock.

What actually happens is that the electricity will flow from the fence to the victim (humans, animals), and from the victim to the ground.

From the ground, the electricity will flow back to the other terminal of the fence charger.

Pulse Fence Charger & Capacitor Charger

Though both types of charger serve the same purpose their working style is different.

Once you’re well aware of their working style you can opt for the one that suits your requirement.

Pulse Fence Charger

As the name suggests, pulse fence chargers are the ones that send voltage spikes to the electric fence at an interval of 1 or 2 seconds.

We need a power source which is generally a 120-volt line and supplies the power to the step-up transformer whose work is to increase the voltage.

Now the AC flows through an electric coil to generate a magnetic field which will further generate an electric current in the second coil.

The higher the number of turns in the second coil the more will be the voltage.

For example, if the second coil has more numbers of turns than the primary one, then the voltage will also be more in the latter one.

A timer is used to send a pulse through the electric fence at regular intervals.

Similarly, a timer is used to send a pulse through the ground rod at equal intervals.

So, now the voltage pulse is flowing through both the electric fence as well as the ground rod.

To complete a loop, something needs to touch both of them at one time resulting in an electric shock.

Capacitor Charger

Unlike the Pulse Fence Charger, Capacitor Charger stores a small amount of electricity.

The major difference between the pulse and capacitor charger is that the electricity may vary in the pulse charger but it will always remain constant in a capacitor charger.

As compared to the pulse charger, a capacitor charger is safer and more reliable because of its capability the electricity provided by the capacitor to the electric fence is always constant.

The working style of the capacitor charger is also different.

Initially, a small amount of voltage runs into the electric fence, and when someone touches the ground and the fence together, the circuits get completed, and voltage triggers an electronic switch, which discharges the capacitor into the fence.

How to Install an Electric Fence at Home?

Installing an electric fence can be a tricky affair if you’ve not done your homework correctly.

Whether you’re a first-time user or an experienced one, keep in mind, you need to do some preparation before you start the installation process.

electric fence installation diagram
Electric Fence Installation Diagram
  • First and foremost, you need to do the measurement of the space where you want to install the electric fence.
  • Once you’re done with the measurement, figure out how much electric wire and metal stakes you’ll need.
  • Before moving to the next step, I highly recommend you should consult an expert if you’re installing the fence for the first time.
  • Now make a list of materials that you’ll need for the installation process such as Electric Fence Wire, Electric Power Box, Metal Stakes, Grounding Post, Plastic Hooks, 8 Round Plastic Rings, 8 pieces of wire, Sledge Hammer, Pile Driver, Wire Cutter, etc.
  • Once you’ve got the metal stake handy, all you need to do is to install it carefully. Layout the metal stakes at a distance of 3 to 5 feet. Then, drive the metal stake into the ground using a hammer.
  • In the next step, you need to wind the wires around the around post. Then, thread the wires between two prongs of the plastic hook and repeat the process for all the posts.

Electric Box Installation Procedure

  • The electric box has a knob titled “ground”, you need to connect it with the grounding post.
  • Similarly, connect the knob titled “fence” to the electric fence using different sets of wire.
  • Before you plug in, the electric box makes sure that the weeds and tall grasses aren’t touching the electric wire.
  • Once you’ll plug in the electric box, you’ll hear a clicking sound that will confirm that the box is sending electricity to the electric fence.
  • Congratulation, you’ve successfully installed an electric fence.

How Can I Choose the Best Electric Charger For My NEED?

Needless to say, the first question that will come to your mind would be, “Which fence charger do I need?”, right?

Nothing wrong with it, the same question came to my mind when for the first time I was trying my hand on an electric fence charger.

However, you don’t have to worry at all, I’ve done all the hard work for you.

I’m assuming that you’ve gone through the section, “How does an electric fence work?” because then only it will be easy for you to figure out the fence charger that will sync well with your requirements.

Let’s have a quick look at some of the commonly used terminology.

Charger Terminology

  • Low-impedance: Definitely, a good electric fence charger possesses this quality. A low-impedance fence energizer means it provides less resistance to the flow of current through the wire. As a result, the power that will flow through the wire will be more and the heat formation will be less. Low impedance is an important parameter and can influence your buying decision in case you’re looking for an energizer that can tackle the highly-dense weeds and long grasses.
  • Solid State: If you want to control short-haired livestock such as small animals, pets, etc, they also perform extremely well against weeds as well. The solid-state electric fence charger delivers a medium range of current and also, the interval at which it delivers current is a medium one.
  • Continuous Output: Well, if you’re looking for an electric fence charger for dairy stalls and smaller paddocks, then definitely continuous output chargers are the better options. Unlike the previous one which has the pulsing charger, the continuous output charger has an unbroken, stable charge on the hot wires.

Types of Fence Chargers

Well, we’re gonna discuss different types of chargers to help you make an informed buying decision.

Having a sound knowledge of different types of fence chargers will definitely help you in narrowing down the options.

So, let’s begin…

Plug-in (AC) Powered

As the name suggests, the Plug-in charger is one that is powered directly by a connection to the powerhouse (electric grid) that you’ve.

Either you can plug the AC charger into the wall or you can use an extension cable for the same.

Moreover, if your fence is in a remote place then I would suggest you should seal the path to add an additional layer of protection to the extension cable that you’re using for connection.

I personally prefer to use an extension cable to power the charger.

To know more about the best sealers, check out our article on the best paver sealers.

It will reduce your work by half if NOT more.

DC (BATTERY) Powered

If you’re finding it difficult to use an AC charger for your electric fence, then definitely you need to try a DC POWERED electric fence.

It gives you the feasibility to operate the electric fence anywhere.

The fence is powered by the battery, so a problem like finding a long cable, sealing the path of the cable, etc will be solved.

On top of it, you can operate the DC-powered fences at a remote location without any hassle.

But, it would be WRONG to say that once you’ve installed the DC-powered fence, you’re done.

In short, you can install and forget.

Here, the power source is a battery that needs to be charged on a timely basis.

So, what you can do is, buy a couple of batteries, so that you can swap them when one needs to be put on charge.

In this way, you’ll protect your livestock from predators throughout the year.

On the flip side, batteries don’t come with an electric fence charger.

Some of them can be recharged while others need to be replaced.

I know you’ll be inquisitive about how many times the battery needs to be charged, right?

Well, it depends.

But, as a thumb rule, you can consider, the charging of batteries to be directly proportional to the number of times the fence is grounded.

So, what does grounding REALLY mean?

In layman’s language, grounding means the number of times the circuit is getting completed.

We’ve already discussed that a circuit can be completed whenever the livestock touches the fence or a weed limb is touching both the fence and the ground.

So, as a newbie, you may not be aware of the fact that if you’re planning to install an electric fence in a highly-dense weeds area, then definitely the battery needs to be charged on a regular basis because some of the weeds limbs will definitely touch both the ground and the fence.

You’ll NOT deny the fact if I’ll say that every process has a learning curve.

So, it will take a while for the livestock to understand that they don’t have to touch the electric fence.

They will learn it the hard way if they aren’t trained previously for the same.

However, a couple of weeks is more than enough to train pets, cattle, etc.

Nonetheless, once the learning phase is passed, you’ll find your batteries to be drained slowly.

So, I would suggest, you should buy a couple of batteries for your livestock learning phase.

Nevertheless, always keep on checking your electric fence for its performance with the help of a voltmeter.

Moreover, if you’re NOT CONVINCED with the benefits of a powered charger, then definitely, stay with us, we’ve got the best offering yet to be discussed.

Solar Powered

Solar-powered electric fence chargers’ are the ones that I always vouch for.

Did you know that the solar-powered charger gets its power from the battery ONLY?

I know you may be wondering then how is it different from the DC chargers, right?

Well, it’s almost similar to the DC charger in most of the cases.

However, unlike the DC charger, here you don’t need to swap the discharged batteries with the charged ones.

The charging part is taken care of by the solar panels attached to the electric fence charger.

The solar-powered chargers are great in the sense you need to worry about charging until the sunlight is available in abundance.

We’ve already discussed solar panel-powered electric fence chargers which can keep working for almost two weeks without the need for sunlight.

The solar-powered energizers are easy to use, portable, lightweight, and durable.

Most solar-powered energizers use acid batteries which are known to last for 1,000 days of charging.


It is really important to figure out what you REALLY need. Failing to do so may lead to the wrong purchase.

If you’re a newbie, then you’ll totally rely on the numbers given on an energizer.

Believing that the product is good, and I too follow the same.

However, you need to understand that what the charger manufacturing companies promise is for the IDEAL SITUATION.

From an ideal situation, I mean no weeds around the fence line, well-insulated, enough moisture in the ground, etc.

Unfortunately, no fence is ideal, and how much effort you put you can never reach perfection.

Even worst, the transfer of electricity from ground rods uses the ground as a medium to traverse which in itself isn’t ideal, right?

So, what’s the solution?

Well, you can use certain parameters and numbers to get an effective charger.

Let me tell you, how you can do that?

First and foremost, you need to understand the difference between the joule and the volt.

V=R/I (resistance/ampere)

Volt is an S.I. unit of electromotive force.

It can be defined as the potential difference that would carry one ampere of current against one-ohm resistance.

On the other hand, a joule is an S.I. unit of energy.

It can be defined as the work done by one Newton when the point of application moves one meter in the direction of the force.

So, how to use these parameters SMARTLY?

Let’s start with joule.

Since it is a unit of energy, it can help you to compare to an energizer and let you know which one out of the two is more powerful.

On the other hand, volt will help you to know the benchmark above which can be dangerous for livestock.

Especially for any kind of animal control, the maximum volts that you need is 7, 000.

Hope I made my point.

Miles is another important parameter that you need to consider seriously.

It talks about an electric fence charger’s capacity to successfully handle a fence of a particular length.

For example, if an energizer says 10 miles, then it means it will be able to maintain a particular current and potential difference at a maximum of 10 miles, exceeding the length of a fence may drastically reduce the performance.

You’ll also find energizer mentioning acres, but I personally don’t believe it to be as important as the previous ones.

The reason being acre is a vague term, indeed.

For example, the distance of fencing around the land of one acre can vary up to 50 percent, and in some cases even more.

Nonetheless, for narrowing down the options, you may consider it as a primary filter.

Electric Fence Charger | Narrowing Down on Options

It goes without saying that the electric fence charger is the heart of the electric fence.

Moreover, the performance of the electric fence to a large extent depends upon the energizer being used to supply joules to it.

Even though you’ve got the best of the electric fence installed perfectly, if the charger is NOT of good quality, then all the money spent on your high-quality fence will go in vain.

Correct me, if I’m WRONG.

A high-quality and highly effective charger will not only keep the livestock inside the fence but also, protect them from predators.

Considering the below points SERIOUSLY can help you to find a great charger, indeed.

First and foremost, refer to this energizer chart to get a clear idea about the joules that you’ll be needing to contain your cattle.

For example, animals that are aggressive or have more hair will definitely need higher joules.

If you’ve got a future plan of expanding your fence area, then definitely you need a strong and powerful electric fence charger.

Though the length of the fence that a charger can effectively manage is given in the specification column.

However, the length that the charger has mentioned is for IDEAL CONDITION which means no weeds around, perfect underground leveling, and so on…

The medium that you use for powering your charger also plays a crucial role in the overall performance of the electric fence.

For example, if your fence is in a remote location, then you should opt for a solar-powered electric charger rather than AC power.

As highlighted earlier also, the benefits of using a solar charger are that you don’t have to swap batteries very often. In the presence of sunlight, the solar panel will charge your electric charger batteries.

Another important parameter that I would like to bring to your notice is the type of net line.

As a first-time buyer, you may not be aware of the fact that poly wire, tape, or even rope create more electric resistance as compared to steel wire.

Even aluminum wire has more resistance as compared to steel wire.

However, if you’re using poly rope then I would highly recommend you should use a fence controller.

When it comes to the number of wires between the two posts, then the thumb rule is, the more the number of wires the higher will be the demand for energy.

On top of it, whenever you’re adding more wires you’ll need more power supply for successfully operating the fence.

When it comes to the consumption of energy, the biggest culprits are the shrubs, weeds, and small plants that are floating around the fence.

They literally suck a lot of energy, so you need to be very careful in dealing with them.

As per my knowledge and experience, the best solution would be to try a net controller that has low opposition.

Without any doubt, they are able to maintain immerse electricity on the fence despite a good percentage of it being drawn by the plants.

Let’s understand it with an example.

The more the number of times the circuit will get completed the faster the battery will discharge.

So, whenever a plant or a weed touches the electric fence, it leads to the completion of the circuit, and as a result, more charge is consumed.

So, if tall grasses and dense weeds are touching your electric fence all around, then be prepared to charge your battery on a frequent basis.

Till now the parameters that we’ve discussed are the ones that we’re capable of changing depending upon our needs.

However, there are certain environmental factors that are NOT in our control, and so, can definitely influence our buying decision.

For example, the conductivity of the soil.

If you’re planning to install the fence in the dry soil which is a poor conductor of electricity then things can turn out to be a nightmare.

The biggest problem with the dry soil is that it can make it difficult for the energizer to push energy from the ground leading to shock when animals come in contact with the fence.

In short, a higher amount of energy would be needed to NOT only complete the circuit but also, generate an effective shock.

So, the question arises, how can one deal with such scenarios?

Well, to minimize the effect of dry soil, all you need to do is to use a ground wire.

You’ll find an extra center wire that runs along the fence.

In case, you’re having frequent trouble with the ground efficiency, then I would highly recommend you try a more powerful energizer to tackle the issue.

As discussed earlier also, undergrowth and weeds around the fence can be troublesome at times, and unfortunately, you don’t have many options available to get rid of them.

Definitely, it’s a common problem with almost all electric fencing.

The undergrowth of the weeds can interrupt the steady flow of electricity through the fence wires, and can even get in contact with the live wires at the base of your fence leading to a significant drain in your charger.

Dealing with the aforementioned problem is NOT as hard as it seems to be.

If you don’t have any time constraints, then I would suggest, you should spend some of your leisure time in cleaning the weeds and long grasses around your fence line.

On the other hand, you can even hire someone for this job.

Nonetheless, buying a very powerful charger can also help you to get rid of such problems.

Do whatever suits you BEST.

Whether you’re planning to use a charger for a single wire or multiple ones, it is always advisable to calculate the requirement of power in advance.

Well, you don’t have to do any complex mathematical calculations.

If you’ve got a ½ mile of 8-wire fence, you would need energy for 4 miles of fence material (8lines * ½ mile = 4 miles).

Once you’re done with the power calculation, it would be REALLY easy for you to narrow down on the options.

Things To Consider When It Comes To Installing Your First Electric Fence Charger

The good thing about most electric fence chargers is that they come with a handbook that has detailed installation instructions.

Some individual components also have their own handbooks to make installation easier for the newbies.

Even though you’re an expert at installing an electric fence, I would suggest, you’ve got a quick look at some of the points that I’ve mentioned below:

  • It is really important to protect your energizer from extreme climatic conditions. Moreover, you need to pay special attention to your electric charger if the box of the charger isn’t waterproof. By simply placing an enclosure around the charger, you can safeguard it against humid conditions
  • If you’re having an AC (plug-in) then you need to place it near a source of 110-Volt AC
  • As a precautionary measure, I would suggest, you should close access to a ground rod system. It will help you to negate any complications as your ground rod will be isolated and separate from other systems and structures
Always use an insulated ground wire to connect the wire (ground) to the ground terminal and ground rods.

Lastly, fix the charger case using screws or nails.


In this section, I’ll be taking some of the frequently asked questions from my readers as well as clientele.

In case, you also have any doubts or queries related to the topic, feel free to ask me in the comment section.

How many volts should my electric fence have?

As per international regulations, the maximum output voltage shouldn’t be more than 10,000 volts.

However, the voltage of an electric fence should fall in the range of 2000 volts and 10,000 volts.

The voltage that you need to supply to your electric fence depends on two parameters: desired power of the shock, and distance on the fence that needs to shock up to.

Does an electric fence have to make a complete loop?

Well, the short answer is a BIG NO.

An electric fence doesn’t need to complete a loop to shock the livestock.

Well, the electric fence charger sends out current to the electric fence on a regular interval.

When an animal touches the fence, the current flows from the wire to the animal’s body, and then, back into the soil to the ground rod system.

Finally, from the ground rod system, it flows back to the electric fence charger, and thus, completes the circuit.
