Not all jump starters are built the same. If you're driving a 4WD, diesel ute, truck, or anything that doesn’t flinch at rough roads — you need gear that matches your rig.
This guide breaks down what makes a heavy duty jump starter actually worth your money. We'll explain the must-know specs, help you choose between 12V and 24V options, and recommend battle-tested jump packs that get the job done — including our own road-ready hero: the Boost N' Inflate.
Understanding Jump Starters
What is a Heavy Duty Jump Starter?
Heavy duty jump starters are portable battery packs capable of jumpstarting larger vehicles — think dual batteries, high-compression diesel engines, or 24V systems. They deliver higher peak amps, more cranking power, and usually have rugged designs meant for repeated use.
Benefits of Using a Heavy Duty Jump Starter
-
Designed for larger engines (diesel trucks, SUVs, utes, work vehicles)
-
Higher reliability under load
-
Reduces downtime in emergencies or remote locations
-
Often includes additional features like air compressors, USB ports, lights
Types of Jump Starters
12V vs. 24V Jump Starters
-
12V: Ideal for most cars, SUVs, and small utes
-
24V: Required for heavy vehicles, machinery, or dual battery systems
Some models support both, but check your vehicle specs before buying.
Lithium-Ion vs. Lead Acid Batteries
-
Lithium-ion: Lightweight, compact, holds charge longer — great for portability
-
Lead-acid: Heavier and bulkier, suited to workshop or fleet environments
👉 Our pick: Lithium-ion for everyday heavy duty use in Australia.
