JUMP STARTER PACKS

Jump Starter Packs

Portable Jump Starter Packs for Cars, 4WDs & Boats

Never get stuck with a flat battery again – our range of jump starter packs at All 12 Volt are compact, powerful, and easy to use. Designed for cars, 4WDs, trucks, and marine applications, they provide reliable emergency power wherever you go.

A jump starter pack is one of the most important pieces of recovery gear you can carry in a 4WD, ute or caravan — and one of the most overlooked. A flat battery in the middle of nowhere, hours from the nearest town, isn’t just an inconvenience. Without another vehicle nearby and a set of jumper cables, it can mean a very long wait for help. A portable jump starter pack means you never need to rely on a passing stranger to get moving again.

Modern lithium jump starter packs are compact enough to fit in a glove box, powerful enough to start a large diesel 4WD engine, and versatile enough to charge your phone, run USB accessories and even inflate a tyre — all from a single device. At All 12 Volt, we stock jump starter packs suited to everything from small petrol engines to heavy-duty diesel 4WDs and trucks, from brands tested to perform in Australian conditions.

Jump Starter Pack vs Jumper Cables — Why Carry Your Own Pack?

Jumper cables have their place — they’re a cheap backup and work well when another vehicle is available. But for anyone who spends time off-road, in remote areas or simply values not being stranded, a quality jump starter pack is non-negotiable kit. It’s the one piece of gear you hope you never need and will be very glad you have.

Lithium vs Lead-Acid Jump Starter Packs

Jump starter packs come in two main types: lithium (lithium-ion) and lead-acid. Lithium has largely replaced lead-acid for portable jump starters — here’s why:

For the vast majority of Australian 4WD owners and campers, a lithium jump starter pack is the right choice. The weight saving alone is significant — a quality lithium pack that starts a 3.0L diesel 4WD weighs under 1 kg and fits in a jacket pocket. The same job from a lead-acid unit requires a unit the size and weight of a small lunchbox.

How to Choose the Right Jump Starter Pack

The two most important specifications to match to your vehicle are peak amps and engine compatibility.

Peak Amps — Matching the Pack to Your Engine

Peak amps (also listed as peak current) is the maximum burst of current the jump starter delivers during cranking. More cylinders and larger displacement means a higher cranking requirement — particularly for diesel engines, which have much higher compression ratios than petrol engines.

Important: always size up, not down. A jump starter rated exactly at your engine’s minimum may struggle on a very cold morning or when the battery is severely discharged. For diesel 4WDs — particularly large-displacement engines like the 4.5L V8 diesel LandCruiser — choose a pack rated for at least 1,500–2,000A peak.

Key Features to Look For

• Reverse polarity protection — alerts you or cuts power if the clamps are connected incorrectly. Essential for protecting modern vehicles with sensitive electronics.
• Short circuit protection — prevents damage if the clamps touch each other before connection.
• Over-voltage and over-current protection — prevents damage to the vehicle’s electrical system during the jump.
• USB-A and USB-C outputs — doubles as a power bank for phones, tablets and cameras when not jump starting.
• Built-in LED torch — critical for night-time breakdowns or dark engine bays.
• IP rating — if you’re using it off-road in dusty or wet conditions, look for IP65 or higher.
• Air compressor (combo units) — some jump starters include a built-in tyre inflator, combining two essential recovery tools in one compact unit.

How to Use a Jump Starter Pack Safely

Modern lithium jump starters are designed to be simple and safe to use — most include smart clamp cables that prevent connection in the wrong order. Follow these steps every time:

1. Turn off the flat vehicle — ignition off, handbrake on.
2. Connect the red (positive) clamp first — to the positive terminal of the flat battery.
3. Connect the black (negative) clamp second — to an unpainted metal earth point on the engine block or chassis, not directly to the negative battery terminal (reduces spark risk near the battery).
4. Turn on the jump starter — wait 30–60 seconds for it to communicate with the vehicle’s battery management system.
5. Start the vehicle — crank the engine for no more than 3–5 seconds at a time. If it doesn’t start after 3 attempts, wait 30 seconds between tries.
6. Disconnect in reverse order — black clamp first, then red.
7. Let the engine run or drive — at least 20–30 minutes to allow the alternator to recharge the battery. If the vehicle goes flat again shortly after, the battery needs replacement.

Note: if the flat battery is physically damaged (cracked case, leaking, swollen), do not attempt to jump start the vehicle. A damaged battery can be a fire and explosion risk.

Jump Starter Pack Maintenance

A jump starter pack you pull out in an emergency must work first time. Keep it ready with these simple habits:

• Charge it every 3–6 months — lithium packs self-discharge slowly but will eventually go flat if left indefinitely. Check the charge indicator and top it up a couple of times a year.
• Store it somewhere accessible — in the glovebox, centre console or a drawer in the canopy. A jump starter buried under gear when you need it is not much help.
• Keep it away from extreme heat — don’t store a lithium jump starter on the dashboard or in a hot boot in summer. Prolonged heat above 60°C degrades lithium cells.
• Test it before long trips — plug in a USB device to confirm it’s holding charge before you head out on a remote trip.

Frequently Asked Questions About Jump Starter Packs

What is a jump starter pack and how does it work?

A jump starter pack is a portable battery unit that delivers a high-current burst to a vehicle’s flat battery — enough to crank the engine and start the vehicle. It connects to the battery terminals via clamp cables included with the unit. Unlike traditional jumper cables, a jump starter pack is self-contained and doesn’t require a second vehicle. Modern lithium jump starters include safety electronics that detect correct connection, prevent reverse polarity damage and regulate the current delivered.

Can a jump starter pack start a diesel 4WD?

Yes — but you need the right pack for the job. Diesel engines have much higher compression ratios than petrol engines and require significantly more cranking current to start. For a common diesel 4WD like a Toyota HiLux, Ford Ranger or Isuzu D-Max (2.8L–3.0L diesel), a pack rated at 1,000–1,500A peak is recommended. For a large-displacement diesel like the Toyota LandCruiser 4.5L V8 diesel or Nissan Patrol 4.2L, go to 1,500–2,000A. Always check the pack’s stated engine compatibility before purchasing.

How long does a jump starter pack last before it needs recharging?

A quality lithium jump starter pack will hold its charge for 6–12 months in storage without being used — much better than lead-acid units, which need topping up every 30–60 days. In terms of jump starts per charge, most mid-range packs will deliver 20–40 jump starts from a full charge before needing to be recharged. Recharging takes 1–3 hours via USB-C or a DC input cable.

Can I use a jump starter pack as a power bank?

Yes — most lithium jump starter packs include one or more USB-A or USB-C outputs and can charge phones, tablets, cameras, torches and other USB-powered devices. This makes them a genuinely useful everyday carry item, not just an emergency tool. Using the USB output regularly also means the pack gets charged and used regularly, keeping the cells healthy.

Are jump starter packs safe to use on modern vehicles?

Yes, when used correctly with a quality pack that includes reverse polarity protection and short circuit protection. The main risk with older-style jumper cables and cheaper units is incorrect connection order or a short circuit, which can damage sensitive vehicle electronics. Quality jump starter packs include smart clamp cables that alert you to incorrect connection and prevent current flow until the clamps are connected safely.

How many times can I jump start a car before the battery needs replacing?

A flat battery that jump starts successfully and then holds charge after a 20–30 minute drive is typically a battery that was simply discharged — perhaps from leaving lights on or a prolonged period without driving. The battery itself may be fine. However, if a battery goes flat repeatedly with normal use, or won’t hold charge after being jump started and driven, it needs replacing. Jump starting a battery that keeps going flat is a temporary fix, not a solution. See our AGM batteries for replacement deep-cycle options.

What is the difference between peak amps and cranking amps on a jump starter?

Peak amps is the maximum instantaneous current the jump starter can deliver — measured at the very beginning of the crank when demand is highest. Cranking amps (CA) or cold cranking amps (CCA) is a more sustained measurement reflecting what the unit delivers over several seconds. Peak amps are often cited in marketing because they sound impressive, but cranking amps are a more meaningful real-world figure. When comparing jump starters, look at both — a pack with high peak amps but low cranking amps may struggle to start a large engine if it drops off quickly.
