Hulk 4x4 HU6514 Heavy-Duty 12V/24V Lithium Jump Starter 15,000A

Professional-Grade 12V/24V Jump Starter Built for Heavy Machinery, Trucks, and Zero-Downtime Operations

Product Overview

The Hulk 4x4 HU6514 is a professional-series heavy-duty jump starter engineered for operators who can't afford downtime. With 80,000mAh (296Wh) of lithium cobalt battery capacity and a 15,000A peak output on 12V systems (6,000A on 24V), it's built for the kind of equipment that smaller portable starters simply can't touch semi-trucks, buses, heavy plant, agricultural machinery, and large diesel engines across construction, mining, and transport industries.

Unlike compact jump starters, the HU6514 features integrated jumper cables, dual 12V/24V output voltage, and a rated lifetime of up to 5,000 starts. It also functions as a multi-output portable power station with four USB-A ports, USB-C input/output, and dual 12V DC auxiliary ports making it a practical on-site power hub beyond its jump-starting role.

Features & Benefits

• 15,000A peak (12V) / 6,000A peak (24V) — handles the starting demands of semi-trucks, large diesel plant, and heavy commercial vehicles that lower-rated starters can't manage
• 80,000mAh / 296Wh lithium cobalt battery — massive reserve capacity designed for repeated heavy-duty use on-site or in the field
• Up to 5,000 estimated lifetime jump starts — long-term reliability for fleet operators and plant managers, not just occasional roadside use
• Integrated jumper cables — no separate clamp storage needed; cables are built into the unit for faster deployment on busy worksites
• Dual output voltage (12V and 24V) — covers the full range of 12V and 24V petrol and diesel vehicles from passenger cars to large trucks and machinery
• 4x USB-A + USB-C output/input + dual 12V DC aux ports — charges phones, tablets, and other devices while on-site; comprehensive utility in a single unit
• LED display monitoring — shows power level, output voltage, and real-time current draw so operators know exactly what the unit is doing at any moment
• Multi-mode LED flashlight (solid/SOS/strobe) — useful for engine bays, dark worksites, and emergency situations
• AC wall charger included — recharges from any 120–240V mains outlet in approximately 8 hours; accepts 18VDC 2A via 5.5mm input or USB-C

Frequently Asked Questions

Can the HU6514 start both 12V and 24V vehicles?

Yes — it delivers 15,000A peak on 12V systems and 6,000A peak on 24V systems, covering both light vehicles and heavy commercial equipment like semi-trucks and buses.

How many jump starts can I expect over its lifetime?

The HU6514 is rated for up to 5,000 estimated lifetime jump starts, making it suitable for fleet operators and plant managers with ongoing heavy-duty starting requirements.

Are the jumper cables built in or separate?

The jumper cables are integrated into the unit — no separate clamp storage or assembly required, which speeds up deployment in worksite and emergency situations.

How is the unit recharged?

It recharges via an included 120–240V AC wall charger in approximately 8 hours, or via the 5.5mm 18VDC 2A input or USB-C port for alternative charging sources.

What USB and power outputs does the HU6514 have?

It features four USB-A ports (5V 2.1A, QC3.0), one USB-C port, two 12V DC auxiliary ports (10A), and one 12V 5.5mm port (3.5A) for broad device charging capability.
