Sealey RoadStart® 12/24V Emergency Jump Starter 3200/1600 Peak Amps RS105

Every busy workshop needs a reliable jump starter that can handle whatever rolls through the doors. This isn't just another booster pack; it's a dual-voltage workhorse built for the demands of a professional environment. When you're faced with a dead battery, you need a unit that delivers consistent power, whether it's a 12V car or a 24V commercial vehicle.

This unit is engineered to tackle a wide range of engines. For 12V systems, it'll confidently start 8-cylinder petrol engines up to 6 litres and 8-cylinder diesels up to 4.8 litres. Switch to 24V, and you're covered for 6-cylinder petrol engines up to 3.5 litres and 6-cylinder diesels up to 3 litres. This broad capability means less downtime waiting for the right tool and more vehicles moved through the bay.

The power comes from two internal batteries, configured in parallel or series as needed to deliver substantial peak and cranking currents. This design ensures you get the grunt required to turn over stubborn engines, even in cold conditions. A critical feature for any mechanic is the low voltage switch, specifically designed for 24V systems. This allows the unit to connect and begin charging a battery that's dropped below 1V, a situation where many standard boosters would simply fail to engage.

Practicality is key in a workshop. The robust composite case includes integral storage for the heavy-duty battery clips and cables, keeping everything tidy and preventing tangles. With a 1.8m cable and clamp length, you've got ample reach to connect to batteries in awkward positions without repositioning the vehicle or the booster. LED indicators and a dedicated test button ensure you always know the unit's charge status, so it's ready when you are.

Beyond starting, the integrated 12V power socket is a handy addition. Use it to power diagnostic tools, charge a mobile device, or run any 12V accessory that uses a vehicle accessory plug. Supplied with a mains charger, keeping this unit topped up and ready for action is straightforward. This isn't a tool you'll regret having on hand; it's an essential piece of kit for maintaining workflow and getting vehicles started reliably.

Composite case with integral battery clip storage and carry handle. Suitable for starting 12V vehicles with 8-cylinder petrol engines up to 6L and 8-cylinder diesel engines up to 4.8L. Suitable for starting 24V vehicles with 6-cylinder petrol engines up to 3.5L and 6-cylinder diesel engines up to 3L. Two batteries, connected in either parallel or series to suit the output voltage, give high peak and cranking currents. Fitted with low voltage switch for use when on 24V system recharge, connecting unit to battery producing less than 1V. LED Battery condition indicators. Test button gives indication of battery condition. Fitted with 12V power socket that will accept any 12V device with a vehicle accessory socket plug. Supplied with mains charger.
