Charger Distance Ratings

Your charger’s effectiveness depends on a number of factors, and one of them is the type of fence line you have installed. Steel wire is the most conductive, so it offers the longest electrifiable distance

Great Charger
May 2, 2018
I have used the Zareba 50-mile AC Powered Low Impedance Charger for several years and am quite happy with it. I bought another as a spare to keep on hand in the event the electrodes wear out or it gets hit by lightning. However, their rod insulators are terrible. I need insulators for the 5/8" (#5) rebar I use as posts. Zereba post insulators (for wire and tape) are near impossible to thread correctly, and they are not open on the end to slip around the post - instead you need slide it over the top of the post. Try doing that when you have 7 wires above the one one you need to replace. The designers of these terrible insulators probably never put up a fence in their lives. The insulators by parmakusa are far superior - easy to install and tough.

Works Great, Even With Weeds!
Oct 11, 2017
I purchased the "Zareba® 50 Mile AC Powered Low Impedance Charger" a few weeks ago. We upgraded from the solar chargers by the same company mainly because after 4 years of use, they were wearing out and my donkeys were learning the shock just wasn't enough to keep them in the fence. After reading the descriptions and reviews to find the right one, we chose this charger, mainly because we do have quite a bit of weed contact on our bottom strand of fence. This fence still gives a good jolt, even with a decent amount of weeds. The best part? The donkeys are still in the pasture!

Can this unit be installed outside?
Question by: David A Pavlovsky on Jul 15, 2022, 6:39 PM
This energizer can be used outside, however, it would need to be protected from the elements or installed in a weatherproof box.
