Top 7 Electric Fence Charger For Bears

Best Electric Fence Charger For Bears

When it comes to farming near woods especially in bear territory, your normal fencing isn’t going to be of much help. Getting through these normal fences can be a walk in the park for bears. The only thing that can give you ample protection from the bears is an electric fence that can make a clear mental imprint in its minds.

The effectiveness of an electric fence against bears depends entirely on the charger that you choose to install in the fencing. Because bears are large animals and they won’t retreat easily like the smaller animals. There are quite a few factors to be considered while you choose an electric fence charger to use against bears.

For instance, impedance, output voltage, input voltage, frequency of the pulses, and a lot more. Apart from being effective, these fences have to be safe as well which is why it is important to choose the right electric fence charger.

When there is an umpteen number of parameters to be considered, choosing the right one isn’t any different than searching for a needle in a haystack! But don’t worry, for we have you covered here.

In this article, we have compiled a list of the Top 7 Electric Fence Charger for Bears. This list has been made after consulting with people who have first-hand experience in using these chargers.

Let’s get going!

What Power Should an Electric-Bear Fence be?

There isn’t a specific voltage that can be effective when it comes to keeping bears and animals at bay. That being said, the experts in the field of fencing says that a minimum of 2000v is needed for effectively tackling animals.

Similarly, as per international regulations, the maximum permissible voltage in an electric fence is 10000 volts. This means you can choose any voltage between 2000 & 10000 volts.

The voltage to be set in an electric fence depends on:

  • The desired power of the shock
  • The distance on the fence that can be shocked up to
  • Size of the property

For a longer shocking distance range, a lower voltage would be used. However, for a greater shock, a higher voltage would be used. In all practical sense, a higher voltage will give you a better edge over the bears. Considering their thick skin and size.


How do I Bear-Proof My Yard?

Bears aren’t like the common intruders you might have come across, for instance like a coyote or a raccoon. They are bigger, stronger & obviously hungrier most of the time which means keeping them at bay isn’t an easy feat to achieve.

There is no doubt that an electric fence is the most effective way to stop the bear from getting into your property. That being said, there are indeed some ways in which you can prevent bears from being attracted to your property.

Let’s have a look at the simple steps that you can take:

Eliminate the tempting odors: Bears are excellent sniffers and they can smell their food from a mile away. If you are living near bear territory, the best way is to avoid them being attracted to your property because of the smell of food.

Make sure that you regularly clean the bird feeders if you have one & never feed your pets outdoor. Even if you feed them outdoor clear away the leftovers fast.

Use a bear-resistant trash can: Bears are opportunistic hunters and they wouldn’t mind eating from the garbage. Make sure that you leave the garbage out for collection shortly before they arrive and that you leave it in a bear-resistant trash can.

Grills: Always be on the watch for bears when you are having an outdoor party. Nothing tempts the bear than the smell of grilled meat. Don’t leave the food unattended when cooking on the grill.


Can Electric Fences Cause Fires?

Yeah, electric fences can cause fires when they aren’t used properly. For instance, during summers the spark from these fences can trigger a fire. One needs to be very cautious while using an electric fence, especially during the dry season.

It is always advisable to check the electric fences to make sure the wires are free of grass, weeds and other vegetation.

Not just the electric fences, any electric device when used improperly can cause severe accidents. Make sure that you adhere strictly to the manufacturer’s guide while using an electric fence charger.


Are Electric Fences Dangerous?

It is a common notion among many that electric fences are dangerous. From what we have understood, we feel that it’s the voltage rating given on the electric fence chargers that scare people. You need to understand that it is not the voltage that kills but it’s the current that’s dangerous.

The purpose of an electric fence is not to kill an animal rather it is to scare away the animal. When it comes to these fences most of them have high voltages running through them for instance 110/120 volts and very small currents in the range of 120 mill amperes.

If you didn’t know, the deadly electrocution stories that you might have heard needs a minimum of 10 amperes. Which is a thousand times more than the current flowing through these fences.

That being said, electric fences aren’t completely risk-free. There are chances for a sudden surge in current due to many reasons. This is where the importance of having a good electric fence charger comes in as most of them have built-in protective fuse panels to avoid this sudden rise in current.
