Small size but pack a punch
This device is small and solidly built. It is very easy to install and self explanatory. I use it to electrify my chicken netting. I am confident my flock will be contained within the perimeter of the fence. Above all, I am confident this device will protect my flock from ground predators. Around here we have: foxes, coyotes, raccoons, dogs, lynxs and cougars.

    It was easy to set up and it worked well for keeping my pigs contained when it wasnt buried under dirt from their rooting.

    It gives one hell of a shock and this year im going to use it to run electric around my garden an chicken coop. All in all i say it was a good purchase, might be better out there for cheaper but im happy enough to not go looking

    Used in a small fenced in area for horses as needed when I can't hook it into my other wired in fencer system.

    The shock is slower but it works. Eventually they got the message and avoid the fencing.

    5.0 out of 5 stars Working great so far w/good zap.
    Reviewed in the United States on June 9, 2025
    Verified Purchase
    So far so good! It was charged when I got it which is great because sunshine is very rare these days. I wasn’t sure how strong it was going to be going by other reviews. I got this fence charger for my horses to cut there limit of grass and a cow got out and ran through it. I went to hook it back after dart and there was a tiny bit of dew already on the ground. It was tied to plastic handle to stop the currant at the fence I had it hooked too. That thing zapped the crap outta me in my rubber muck boots! I had to turn it off to hook it back. LOL. So yeah. I think it probably has a good zap to it. My ground rod is not even that long as we didn’t have anything to fit the grounding rod/ mounting post, which are one and the same. I didn’t realize that when I bought it. No big deal. We just a ways from town. But it’s been so wet that a 2’ one works for now.

    5.0 out of 5 stars Great unit, one year later with no issues
    Reviewed in the United States on June 1, 2025

    I've had this electric fence energized for nearly a year and it has work flawlessly the entire time. I am using this to protect a grove of fruit trees from my local neighborhood deer who will eat nearly every plant in my yard. This electric fence energizer has kept the deer out completely. I have 5 strands of wire, approximately 75' long each. The solar aspect is great and has kept me from having to run power out to the fence. Another great aspect is that the grounding rod acts as the support for the energizer and has an alligator clip from the positive and just clips on to the wire. I never have turned the unit off, just simply disconnect the alligator clip and address my trees. Highly recommended and will most likely buy another once I get another garden set up

    4.0 out of 5 stars Working well. Had it a year
    Reviewed in the United States on April 4, 2024

    We live in a deer super highway, a clearing in the woods between the forest and the river. The deer like to gather and sleep here. The yard is all torn up. Trees regularly get stripped of their bark. But, the gardens, including delicious spring tulips, hostas, lilies, roses, and other tasty treats have not been eaten at all since using this energizer.

    Used the energizer and 3+ foot some step in stakes to fence off my flower gardens. Goal was to prevent deer and rabbits from ruining the garden.

    The step in stakes have at least five places to attach wire. i started off with hot wires on the top (1) and bottom levels (5). The deer leaned over it and then left. Found the wire stretched and some footprints inside the garden but nothing eaten.

    I added two ground wires at the 2 and 4 positions on the stakes. The grounds go back to the grounding stake. When an animal touches the hot and ground, they complete the circuit and get zapped. Since making this improvement, we haven't had a deer get near our gardens.

    Rabbits are still able to jump between the hot and ground and get into the garden. I haven't seen any appear to get shocked. But, often they just run around the outside. So, i suspect the fence has had some effect on them. To improve my system, I should get a longer grounding rod. Current one is thin and only three feet. The natural soil here is mostly sand and gravel.

    Will buy another energizer today. Have a bunch of young trees to plant. Need to keep the deer off untl they mature a bit.

    Definitely recommend the product for deer. Gave it 4 stars because I'd like to see the rabbits once and a while.... But, my inadequate setup may be to blame.
