Hotline Gemini 40

12 Volt AND Mains Energiser

With FREE stand and earth stake!

This energiser is a real gem.  Made here in the UK, it can work from either a 12 volt leisure battery OR from the mains. This gives you flexibility to move your fence around, should you need to.  It can power up to 8km under perfect conditions, and up to 4km with medium vegetation.   It has an 0.45 output Joule rating.  It is ideal for paddocks, strip grazing and poultry nets.

It comes with an impressive 5 year warranty.

The energiser will run off a 12 volt battery for approximately 5 weeks, and it has a low battery and electric fence pulse indicator.  It is good for all electric fence rope, tape, wire  and twine.

The Gemini 40 comes with earth, fence and battery leads and 12v mains adaptor; it can be mounted on either a wall or wooden post, or on the stand included with the energiser.  The stand will work as an earth stake for most small to medium fences.  For larger fences, you may need to add a 50cm earth stake.


  • Stored energy - 0.8 Joules
  • Output energy - 0.45 Joules

We say:  This is a great, compact energiser from a British company.  What's not to like?


Note: If you are running the energiser on the Mains, you may need to add some High Voltage Lead Out Wire to get from the energiser to the fence. This comes in rolls of 25m, 50m and 100m.
