5.5J Electric Fence Charger Energizer, 5.5 Joules 10 Miles, AC DC 2 in 1 Powered Supply, Input 12V Output 8 KV or 12KV, with Display and Alarm, Contain Cattle Cow and Livestock, No Remote

fence charger is bad ass. But the 110 to 12 volt converter went out, when it goes out buy new one for 8 dollars. cows dont get near it, it will roll them up!

Worked well for the first 4 months then the 12kw post went dead. Switched to the 8kw post and continued to use. That was fine since the 12kw had given my livestock a healthy respect for the fence. I bought this energizer Feb of '24 and now it’s April of '25 and the energizer has completely stopped energizing the fence. Instead, it apparently is energizing itself though. Last night while trying to test the outputs since the fence is dead (but the battery still shows 11.9 volts) the dang thing gave me a full body hit when I touched the orange plastic case - not fun and l am still sore all over the next day. l am now looking to replace since apparently there is no Warranty on this unit...

The seller (also the manufacturer?) reached out to me after seeing my review and went above and beyond to make it right about the power supply. Really excellent customer service. I have had the fence running for a few weeks now and so far everything is great. I am showing little to no voltage drop across my small < 5ac fence. The alarm feature has already proved useful once, as I had an insulator crack and start to short intermittently, a fault I only discovered by hearing the alarm start to "chirp" in short (loud) bursts. Excellent! Original review follows: ********** The unit offers a lot of features, is powerful, and the main unit itself, despite some typos, seems well made overall (though I've only had it running a day). All that said, the included power supply was both obviously poorly made (it feels like it weighs about half an ounce) and was completely defective out of the box. It was a pretty standard 12V 2A power supply though, so I scrounged around the house for another one, which fortunately I was able to find. That makes this hard to rate. Had the included power supply worked and been decent quality, I would have rated it five stars. As it stands, 3 at best.

It’s working great for a week now but the comments about the wire binding posts are spot on, the nuts are useless as they have no washer or flange and the plastic covers on the nuts are are garbage - so be prepared to secure wires to a post without a nut. Otherwise I’m quite satisfied so far. I see comments tht the power supplies fail easily and I work with electronics for a living and can see they aren’t robust. However they are easily replaceable inexpensively with a more robust replacement on Amazon if you know how to match or rewire a barrel connector. Overall it’s great for me as long as the main unit works and I’m very happy with the price. Better binding posts would have earned 5 stars, there’s really no excuse for how terrible the nuts are!

I bought this to replace a solar charger that wasn't up to the task of charging my expanded paddock (added some cows to the property). The fence charger itself is pretty great. It's strong, simple, and has been reliable (other than the issue described below). Cons are simple: -The green 'on' light is way too bright and obscures the handy red pulsing light that lets you know it's sending a charge down the line. -The connectors for the fence lines are cheesy. But, they work, so... whatever. Just be careful not to jostle them. PROs? -Very simple device -Loud alarm to let you know when there's an issue. -Fairly rugged -Small and compact -It works. And it hurts. WAY more than my previous solar charger. -Runs on 12v... just throw a car / lawnmower / whatever 12v battery on it and you have an off-grid charger. The REAL cons are the support. The provided power supply failed in a week of use. In contacting support, the ONLY OPTION is to return the item for a refund. They will not send parts, they will not do a replacement, nothing. Just return for refund. I couldn't be without the charger, so I opted to accelerate my plans of putting a battery on the system. Found a good barrel connector and old battery laying around, and got it going again, no thanks to support. Right now I'm charging the battery with an old car charger, but I'll grab a cheap solar panel and it will be totally off grid. If your charger 'fails', check the cheesy chinese power supply. Hook up a battery or replacement 12v power supply, and boom, you're up and going again. Forget the folks at support, they're no help at all.

The product has work flawlessly to specification for 6 months now. In response to those that complain about it failing, note that it is important to have a really good electrical ground - follow the instructions. Because my soil can get dry in the summer, I am using three ground stakes, three feet apart and each 32 inches deep. A good ground minimizes internal stress on the electronics. Also, keep the charged wire free of weeds or other things that can cause leakage to ground. This will keep the output at maximum effectiveness and improves battery life. I am using this for a plant nursery to keep the deer out. Having been in operation for some time now, there is never a deer print near it. They've learned to stay away. Lot's of videos on line can show you how to arrange an effective electrical fence for deer. I am running the unit off of a deep cycle heavy duty 12 volt battery charged by solar panels that are sized for the load, a completely off-gird system. I am quite satisfied with this product so far. And plan to purchase another.

Commandé et arrivé dans les temps mais seulement le boitier reçu… aucun fils de branchement donc pour l’instant, non Utilisable.

I bought two of them, one in April and one in May, the one I bought In May started to show that it was only receiving 9v. I tested my battery and confirmed the battery was at 12 V, and I tested the voltage at the power supply wire and it was 12 V. I opened the unit and saw this circuit on the board. This unit lasted me 3 1/2 months.

As a follow up to my first review, don’t buy any of this junk. 160 bucks plus is a lot to throw away on a total piece of junk. 6 weeks and ready for the garbage. Crap, crap, crap.
