Quick Answer: To use a Kings jump starter, turn it on, connect the red clamp to the flat battery’s positive terminal, the black clamp to an unpainted metal ground point, switch the unit’s jump-start mode on, then start the vehicle. Disconnect black first, then red, once the engine is running.
A Kings jump starter is a compact lithium-ion power pack built by 4WD Supacentre’s Adventure Kings range, designed to get a flat car, 4WD, or camping battery running again without needing a second vehicle. Knowing exactly how to use a Kings jump starter properly matters more than most drivers realise, because the clamp order, timing, and mode settings all affect both safety and how well the jump actually works. This guide walks through setup, connection order, starting technique, and what to do if the jump doesn’t take the first time.

What a Kings Jump Starter Actually Does
A Kings jump starter is a portable lithium battery pack with heavy-duty clamps attached. Instead of borrowing power from a second car’s battery, it uses its own internal cell to send a short, high-current burst into your vehicle’s flat battery. That burst is usually enough to turn the starter motor over and get the engine running, after which your vehicle’s alternator takes over charging duties.
Most Kings units are rated in the 1000A–2000A peak range, which is generally enough for a standard 12V passenger car, SUV, or a mid-size diesel 4WD. Understanding how to use a Kings jump starter correctly starts with knowing this peak rating isn’t the same as sustained output — it’s a short, controlled spike designed for the few seconds it takes to crank an engine.
Why the Setup Sequence Matters
Skipping steps or connecting clamps in the wrong order is the single biggest cause of jump starter mishaps. Reverse polarity, sparking near the battery, and clamp slippage are all avoidable when you follow the sequence below and give each step a moment to settle before moving to the next one.
Before You Start: What to Check First
Before you learn how to use a Kings jump starter on an actual flat battery, run through a short pre-check. This protects both the unit and your vehicle’s electrical system.
Things-to-check checklist:
In practical terms: if any of these boxes aren’t ticked, sort that out first — a swollen or leaking battery, for example, is a job for a professional, not a jump start.
Step-by-Step: How to Use a Kings Jump Starter
Here is the practical sequence I follow when using a lithium jump starter like the Kings unit. Each step matters, and the order is not interchangeable.
Power on the unit. Press the power button and confirm the display or LED shows a working charge level. If it’s low, charge it before attempting a jump.
Connect the red clamp to positive (+). Attach it firmly to the vehicle battery’s positive terminal, usually marked with a “+” and a red cover.
Connect the black clamp to a bare metal ground point. Use an unpainted metal bracket or chassis point away from the battery and fuel lines, not the negative terminal itself, where possible. This reduces spark risk near battery gases.
Switch the jump starter into jump-start mode. Many Kings units require you to press the power button again once clamps are attached, so the reverse-polarity protection can confirm a safe connection before allowing output.
Start the vehicle. Turn the key or press start. If the engine doesn’t catch within 5-8 seconds, stop, wait 2-3 minutes, and try again rather than cranking repeatedly.
Disconnect black first, then red. Once the engine is running, remove the black (ground) clamp first, then the red (positive) clamp. This order lowers the chance of an accidental short.
Let the vehicle run and recharge the jump starter. Drive for at least 15-20 minutes so the alternator can rebuild the battery’s charge, then recharge the jump starter itself before storing it.
Connection flow at a glance:
🔴 Red clamp → Positive terminal
⚫ Black clamp → Bare metal ground point
🔵 Power on → Start engine
⚫ Remove black → 🔴 Remove red
Practical guide: keeping this order fixed in your head means you can jump-start confidently even in the dark or in a stressful roadside situation.
Is a Kings Jump Starter Right for Your Vehicle?
Not every jump starter suits every engine size. Here’s how peak amperage generally lines up against common vehicle types in the Australian market.
Device Fit by Vehicle Type
Tip: If your 4WD has dual batteries or a large diesel engine, check your specific Kings model’s peak amp rating against your engine size before relying on it as your only backup option.

Safety Considerations When Jump-Starting a Battery
Car batteries produce hydrogen gas during charging, and a spark near the terminals can, in rare cases, ignite it. Learning how to use a Kings jump starter safely is as much about what you avoid doing as what you do.
Safety Note: Never connect the black clamp directly to the negative terminal of a battery that looks swollen, cracked, or is leaking fluid. Use a metal ground point instead, and avoid smoking or using open flames near the engine bay during the process.
Heads-Up: Double-check clamp polarity before switching the unit on. Most Kings jump starters include reverse-polarity protection that stops current flow if clamps are reversed, but this should be treated as a safety backup, not a reason to skip checking manually.
Safe-Use Decision Path
Before connecting, ask:
Is the battery swollen, cracked, or leaking? → Stop, call a professional
Is the jump starter charged and undamaged? → If no, charge it first
Are terminals accessible and clean? → If no, clean gently before connecting
All clear? → Proceed with red-then-black connection order
This decision path is a practical guide, not a substitute for manufacturer instructions specific to your model.

Common Mistakes vs Better Practice
Relative priority when preparing to jump-start:
Charge level check
Clamp connection order
Post-jump driving time
Storage temperature
This is a practical guide to relative priority, not a scientific ranking — clamp order still matters most for safety even though charge level often causes the most failed attempts.
Pro Tips: What Experienced Owners Check
Check the charge before every trip
Experienced 4WD owners top up their jump starter before a long trip rather than assuming it’s ready. A unit that sat unused for months may have partially discharged.
Store it at moderate temperature
Leaving a lithium jump starter in a hot glovebox or a freezing canopy can shorten its lifespan. A cabin storage spot is generally better for longevity.
Inspect the clamps regularly
Worn or loose clamp jaws reduce contact quality and can cause sparking. A quick visual check before each use catches this early.
Know your engine’s real amp needs
A beginner might buy based on price alone. An experienced owner checks their engine displacement and fuel type first, then matches the unit’s peak amps to it.
When to Contact a Professional
When to contact a professional: If your battery repeatedly fails to hold charge, shows physical damage, or the vehicle has an underlying electrical fault beyond a simple flat battery, stop using the jump starter and consult a qualified auto electrician or mechanic. This is also appropriate if you’re unsure whether your vehicle’s warranty terms allow DIY jump-starting, or if local regulations affect roadside procedures in your area.

Frequently Asked Questions
How do I use a Kings jump starter on a completely dead battery?
Follow the same red-then-black connection order, then switch the unit to jump-start mode before attempting to start the engine. If the battery is very deeply discharged, allow the jump starter a minute or two connected before cranking, as this can help the battery accept charge more readily.
Can a Kings jump starter damage my car’s electronics?
When connected correctly with the built-in reverse-polarity protection active, a Kings jump starter is generally designed to avoid damaging vehicle electronics. Incorrect clamp placement or a faulty unit can pose a risk, which is why checking polarity before switching on is important.
How long should I keep the clamps connected after the engine starts?
Only a few seconds. Once the engine is running smoothly, disconnect the black clamp first, then the red clamp, and let the vehicle idle or drive to allow the alternator to continue charging the battery.
Is a Kings jump starter suitable for diesel 4WDs?
Many Kings jump starters with a peak rating of 1500A or higher are generally suitable for common diesel 4WD and ute engines. Check your specific model’s peak amp rating against your engine size before relying on it as your primary backup.
Why won’t my Kings jump starter turn on?
This is most often a discharged internal battery. Charge the unit fully using its supplied cable, and if it still won’t power on after a full charge cycle, the internal cell or charging port may need professional assessment.
Do I need to disconnect the car battery before using a jump starter?
No. A jump starter is designed to connect directly to the existing battery terminals while it’s still installed in the vehicle. There’s no need to remove or disconnect the battery itself.
When should I take my car to a mechanic instead of jump-starting it again?
If your battery goes flat repeatedly within a short period, or the jump starter won’t get the engine to catch after a couple of attempts, it’s a sign of an underlying issue that a qualified mechanic or auto electrician should check rather than continuing to jump-start it.
Final Thoughts
Learning how to use a Kings jump starter properly comes down to a handful of habits: keep it charged, follow the red-then-black connection order, give the engine a moment between attempts, and disconnect black before red once it’s running. These small steps protect both your vehicle and the jump starter itself. For anything beyond a simple flat battery — repeated failures, battery damage, or electrical faults — check your vehicle’s manual and consult a qualified mechanic or auto electrician before continuing.
