9J Electric Fence Charger - Bear Protection

9J Electric Fence Charger – Maximum Power for Large Farms & Serious Livestock Management

When standard fence chargers don’t cut it — when you’re managing large herds across wide pastures, facing aggressive predators, or dealing with overgrown vegetation on fence lines — you need a high-joule energizer built for the job. The LIFEALL XSD-A7+40 9J Electric Fence Charger delivers professional-grade output with the flexibility to run on AC power, 12V battery, or solar panel, and includes a wireless alarm system and remote control for complete perimeter security.

Key Features

• 9 Joules Stored / 8 Joules Output Energy — One of the highest-output fence chargers available. Powerfully deters wolves, coyotes, bears, and other predators while keeping cattle, horses, and livestock securely contained.
• 12KV High Output Voltage — Effective even through moderate vegetation on fence lines. DC input 12V, output up to 12KV maximum.
• 20-Mile / 400-Acre Coverage — Powers up to 20 miles (32km) of fence line, enough for large multi-paddock operations.
• 3 Flexible Power Sources — AC adapter (110–240V), 12V battery, or solar panel — choose what suits your property.
• LCD Display + 3-Color LED Indicators — Real-time output voltage (KV) and input voltage (V) on screen. POWER / FAULT / SHOCK indicators at a glance.
• Built-in Alarm + Remote Control — Wireless alarm horn alerts you when the fence is breached. Remote ON/OFF control without walking to the unit.
• Adjustable Sensitivity — Dial the shock sensitivity up or down to suit your livestock type and fence conditions.
• Waterproof & Outdoor-Ready — Reliable operation in rain and harsh weather.

Smart Control Panel – Everything at a Glance

The front panel puts complete operational intelligence in front of you:

• Output Voltage Display — Large red LED shows real-time KV output
• Input Voltage Display — Battery bar graph + numeric V display
• POWER indicator — Green LED confirms unit is energized
• FAULT indicator — Red LED warns of short circuit or fence fault
• SHOCK indicator — Pulses with every fence discharge cycle
• Sensitivity Dial — Adjustable from low (−) to high (+) for different livestock
• EARTH terminal — Ground rod connection point
• 12KV terminal — High-voltage fence wire connection

Bottom panel: separate power interfaces for direct AC use vs. remote-controlled alarm mode, plus the dedicated alarm output port.

3 Ways to Power Your Fence – No Compromise on Location

All three sources connect to the same unit — switch between them as your needs change without buying a different charger.

What’s in the Box

• Alligator Clip Cable — Red for positive (+), black for negative/ground (−). Connects the charger directly to a 12V battery.
• Alarm Horn — Emits a loud sound when triggered by fence breach to alert or warn animals. Mounts separately from the main unit.
• DC 12V 1.5A Power Adapter — Provides stable DC power supply for the alarm system when using AC input.
• Remote Control — Wireless ON/OFF for the alarm system. No need to walk to the fence charger to disable the alarm.
• Screws & Washers — Mounting hardware to secure the unit and prevent vibration loosening.

Installation Guide

1. Mount the charger — Fix to a post, wall, or barn using the included screws and washers in a sheltered, ventilated location.
2. Drive grounding rods — Insert 1–3 steel rods (1.5m each) into moist ground. Poor grounding is the #1 cause of unit damage — do not skip this step.
3. Connect ground wire — EARTH terminal → grounding rod with insulated lead wire.
4. Connect fence wire — 12KV terminal → metal fence wire via insulated lead.
5. Connect power source — Plug in AC adapter, connect solar panel, or attach battery clips (red=+, black=−).
6. Set up alarm (optional) — Connect alarm horn to the alarm interface on the bottom panel. Pair remote control.
7. Power on — POWER LED turns green; LCD shows live output voltage immediately.

Please Note: Do NOT touch the unit or fence wire while energized. Keep children away from fence lines.

Who Should Buy This?

The LIFEALL 9J Charger is the right choice if you:

• Manage large cattle, horse, or livestock operations where high joule output commands animal respect
• Face heavy predator pressure — wolves, coyotes, bears — that low-joule units cannot reliably deter
• Have fence lines with vegetation contact that drain energy from standard energizers
• Need flexible power — AC one season, solar or battery the next
• Want alarm + remote monitoring so you know immediately if a fence breach occurs
• Operate in wet or rainy climates and need a weatherproof outdoor unit
