AKO Power Shock B 290 Electric Fence Energiser for small pastures

The AKO Power Shock B 290 is a high-impact 9V universal electric fence energiser built for small to medium fences with light vegetation. Whether you're securing horse and cattle paddocks, portion grazing, or enclosures for pigs and poultry, this battery-powered energiser keeps your animals safely contained. Thanks to its low amperage, it's also well suited for small pets such as dogs or cats.

The manual rotary switch lets you adjust the impact strength across 5 levels, so power consumption can be efficiently regulated to match your fence conditions. A multi-level LED bar (green, yellow, red) provides a clear visual check of fence output, while a separate indicator shows battery status. The rugged, weatherproof housing was purpose-built for field use, offering excellent break resistance and an ergonomic carry handle for easy transport.
