Built in Belgium with top‑tier components, this booster delivers reliable, instant starting power for both 12‑volt and 24‑volt vehicles, including commercial fleets, trucks, buses, and heavy‑diesel applications.

• Powerful, versatile performance: 12V/24V operation with 2400 peak amps and 1200 cranking amps ensures quick starts for marginally discharged batteries across a wide range of vehicles and engines.
• Rugged, maintenance‑friendly design: a single‑piece, 5 mm polyethylene case provides exceptional shock resistance and long‑term durability. The design is purpose‑built for daily professional use with a lifetime warranty against breakage.
• Built‑in safety and protection: an internal fuse guards the system from short circuits, protecting both the booster and the vehicle electrical system during every jump.
• High‑quality, flexible starting cables: double‑insulated clamps with high conductivity are designed for frequent handling and allow you to leave the booster on the ground while starting, reducing strain on cords and connectors.
• Smart monitoring at a glance: a bright, illuminated voltmeter shows the booster’s charge level, charger status, and confirms the vehicle’s alternator health during operation.
• Advanced battery technology: AGM batteries with pure lead provide high current delivery and efficient energy transfer, enabling rapid cranking even when batteries are not at full capacity.
• Professional‑grade cables and connectors: robust, high‑conductivity starting cables and connectors designed for frequent use in service environments and remote locations.

Practical tips for optimal use:

• Charge the unit fully before first use and during downtime to ensure maximum readiness.
• Connect red to positive and black to a solid metal ground on the vehicle; keep away from the battery’s venting area.
• If you’re jump‑starting a heavy vehicle, allow the engine to engage after a brief crank to confirm a stable start.
• Use the illuminated voltmeter to verify both the booster charge and the alternator health during the process.
