Hulk 4x4 HU6512 Lithium Jump Starter 28,000mAh 2,500A Portable

The Biggest Jump Starter in the Hulk 4x4 Range 2,500 Amps of High-Density Lithium Power

Product Overview

The Hulk 4x4 HU6512 sits at the top of the Hulk jump starter range, packing 28,000mAh of high energy density lithium cobalt battery capacity and a 2,500A peak output to handle the most demanding engine starts petrol up to 10.0L and diesel up to 8.0L. That puts it in range for heavy 4WDs, large commercial vehicles, trucks, and high-displacement diesel rigs where a standard jump starter simply won't cut it.

Like the rest of the Hulk range, it doubles as a portable multi-output power station with dual USB ports, DC outputs across 12V, 16V, and 19V, and an included laptop adaptor harness and 240V AC charger. The multi-mode LED flashlight, multi-function LED display, and rubberised housing round it out as a practical all-in-one emergency kit for serious touring, worksite, and remote use.

Features & Benefits

• 2,500A peak / 1,200A starting current — the highest output in the Hulk 4x4 jump starter range; rated for petrol engines up to 10.0L and diesel engines up to 8.0L, covering heavy trucks and the largest 4WDs on the road
• 28,000mAh high energy density lithium cobalt battery — larger reserve capacity than lower models means more start attempts and longer device charging between recharges
• Spark-proof, reverse polarity clamps — safer clamping under the bonnet, particularly useful on large engine bays and in remote or low-light conditions
• Multi-voltage DC output (12V / 16V / 19V at 3.5A) — charges laptops and DC-powered devices without needing mains power; dual 12V and 19V outlets both rated at 3.5A
• Full accessory kit included — 240V AC charger, car charger adaptor, laptop adaptor harness, and 4-in-1 USB cable cover virtually every charging scenario
• Multi-function LED display — shows battery charge level and current draw before and during a start attempt
• Multi-mode LED flashlight (solid/SOS/strobe) — practical for roadside breakdowns, remote camping, or emergency signalling
• Black and grey rubberised housing — impact-resistant construction for life in a ute tray, toolbox, or boot
