O’Brien’s Little Demon Energiser.

The small fencer that packs a punch!  This is a simple, convenient way to electrify breaks of grass that are not served by mains electric fence.  No more charging or carrying heavy leisure batteries! Great for use with horses.

•    Choice of convenient connection by hanging on wire or via small crocodile clip connector.
•    Gives highest voltage under load when compared with other products.
•    Sold inc. battery. Replacement batteries available

KiwkiKit comment: We have found this fencer works really well on our farm.  Easy to move and the batteries last well. Surprisingly powerful for its size. Popular with all who use it - except the cows and horses!
