Our Comprehensive Buying Guide


In case you have been looking for a specific type of unit such as the best electric fence charger for goats, then you’ve surely read multiple reviews that include specific terms you might not understand. If you are rather new to what using an electric fence charger entails, then these next lines are going to clear things out, so that you know what to choose.




Electric fence chargers are special devices that can power the line around your property, even when we’re talking about a weeded one. A low-impedance unit means that the resistance within the charger is reduced so that more power can get through the wire. As you can imagine, these units are preferred by experienced users, as they ensure great results in all types of conditions.

There are also solid-state devices that can deliver shocks at medium amperage and of medium duration. If you need to control pets, small animals or short-haired livestock, then this is the alternative to go for. What you need to keep in mind is that, most of the time, these models work in light weed conditions.

Electric fence chargers with a continuous output mean that a constant charge is present on the hot wire, the alternative being pulsing charges. Units with continuous current are mostly recommended if you have dairy stalls or small paddocks on your property.


Types of chargers

There are three main types of electric fence chargers, namely AC-powered, DC-powered, and solar-powered ones. While things might seem pretty straight-forward when it comes to this matter, the truth is that choosing the right electric fence energizer is very important in order to keep animals safe. After all, this is a preventive measure that shouldn’t hurt them at all.

The first thing you should consider is the source of power, as this is the main aspect which can determine the type of charger you need to use. If you have a power plug that you can use on your property, then an AC-powered unit can be used without any trouble. If, however, you don’t have a nearby power-source, then you’ll probably use the DC alternative that comes with batteries.

One important thing to note is that if you do have access to AC power, then going for this alternative is more convenient, as these units usually have greater energy output and are more convenient. Plus, in the long run, you have more flexibility, in case you want to expand the area.


A bit about solar-powered models

The lack of AC outlets can otherwise prove to be a problem, so choosing such a unit is a very good alternative. Solar-powered models are lightweight and easy to transport around, while they also include a battery for energy storage.
