Product Information

The TB1224HDD is a robust 12V/24V jump start pack designed for heavy engine starting. The increased battery capacity is ideal for using within the bus, truck and plant industries for maintenance operations such as fuel bleeding, oil pressure build-up, tail lift cycling as well as multi engine starting.

The robust powder coated steel case is designed to deal with the harshest working environments and houses 2 x 26Ah dry- cell batteries isolated by a heavy-duty 1000amp key switch isolator with dustcover.

The pack is fitted with 2 x 2.3A independent internal chargers that maintain the batteries separately, ensuring maximum battery longevity is achieved. The TB1224HDD shares many of the safety features associated with Powervamp’s premium range of jump starters such as reverse polarity audible warning and voltage spike suppression circuitry for ECU protection.

The standard 2m, 50mm2 highly flexible, output cables allow the operator to safely connect to a flat battery within the engine bay whilst the pack remains on the floor. The cables terminate with fully cast 1000A braided croc clips, ensuring an equal power delivery with minimal volts loss. The cables are detachable to allow for easy storage or replacement.

Optional accessories include bus plug (cowbell) lead sets and a powerful 24V inspection lamp.
