Description
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.
