  • Reliable Solar Fence Charger – Easy Setup and 24/7 Protection!
Size: MINI160-Rear switch
I recently purchased the 10 Miles Solar Electric Fence Charger, and it has exceeded my expectations! Setting it up was straightforward, and the portable design makes it easy to move between fences if needed. I love that it has a day/night mode and a rechargeable solar panel, which keeps my fences powered 24/7 without any hassle. I feel confident knowing my livestock is protected without constantly checking or replacing batteries. Overall, it’s efficient, easy to use, and great value. Highly recommend for anyone looking for a low-maintenance, solar-powered fence charger. ... show more

  • Great devices but need a bird deterrent
Size: MINI160-Rear switch
I bought two of these devices. They are really good and work like they should. I use them for deer control on flower beds and the garden. I set them up in the spring and take them in after the frosts have killed off all the vegetation. One is 4 years old and the other is 3. One thing the devices really NEED is a bird deterrent, otherwise they will soon be covered on bird droppings. I made mine out of some roof flashing and 2 inch drywall screws. Sorry birdies find some other place to perch. Sometimes it is difficult to get the battery back in correctly. Otherwise a great product. ... show more

  • Nice design, and easy to use, but ineffective in my application to deter the deer from my garden.
Size: MINI160-Rear switch
I am disappointed. Very disappointed! Although it presents itself as a good valve for the money, and certainly easy to use (set up) it, in my experience and opinion, sorely lacks the power needed to dissuade and deter certain predators. It is advertised as up to 10 miles, but the model I received states up to 2 miles. (That’s quite a disparity!). But my application is for a very small garden area to keep the deer away. To my surprise and utter disappointment it did not deter the deer at all! It was eating away on my squash plants. No doubt It would have done more damage, had the camera no activated notifying me some was there. (This was at night.) I hurried outside and shooed it way. ... show more

  • Easy to use.
Size: MINI160-Rear switch
Easy to install on T post. Isn't very strong, have it around a small garden to keep deer and rabbits out. Works well, self contained unit.

  • Very low quality
Size: MINI250-Rear switch
Hello, I started using this solar electric fence charger (HELIOS Mini 250) in the fall of 2024. It initially worked as expected, but this past fall it began to perform poorly, and now it has completely stopped working. This product is used to power an electric fence for containing large animals, and its failure is a serious issue. I expected a reasonable lifespan, but the product failed far too soon. I am requesting a full refund for this defective product. Please advise how to proceed. ... show more

  • Great price for a high quality item
Size: MINI160-Rear switch
Easy to setup, long lasting battery powered by solar. Easy to mount. We bought this to keep some cows out of our yard and it’s working perfectly.

  • Love it. Worth it for horses all day
Size: MINI400-Rear switch
Plug and play. Awesome output even on fence that's old and likely has a lot of resistance. Keeps the sassy pony and his taller friends in no problem as well as keeping the overzealous dog out as well. Sits right on top of a T-post in a pre-fabricated slot in the bottom for easy attachment. Not nails, no intense installation. Plus the T-post is a handy, instant ground rod to boot. So the convenience is great. The auto/night feature is awesome too. Very happy with this set up so far. Have used since spring (about 4 months) and am satisfied enough to where I ordered another one. ... show more
