Sealey RoadStart® 12V Emergency 4-Cylinder Jump Starter 2L RS1B

Sealey RS1B 12V Compact Jump Starter – Essential Power for Smaller Engines

Every workshop needs a reliable, portable power source for flat batteries, and the Sealey RS1B is engineered for exactly that. Designed specifically for the everyday demands of mechanics working with smaller vehicles, this unit delivers consistent starting power without the bulk.

When you're faced with a dead battery on a 4-cylinder petrol or diesel engine up to 2 litres, the RS1B provides up to 1100 Peak Amps. This is ample power to get most standard family cars and light commercial vehicles firing again quickly. Crucially, it incorporates robust reverse polarity and short circuit protection, complete with an audible warning. This isn't just a safety feature for the user; it actively safeguards the vehicle's sensitive electronics from costly damage – a real workshop benefit that prevents headaches and additional repair time.

Beyond jump starting, the RS1B proves its worth as a versatile power hub. The integrated LED worklight illuminates dark engine bays or workshop corners, saving you fumbling for a separate torch. You'll always know the unit's readiness thanks to the clear internal battery charge level display on the front panel. For powering ancillary equipment, it features two 12V accessory sockets, perfect for running diagnostic tools, inspection lamps, or even a tyre inflator if needed. Plus, the 5V 2.4A USB output is a practical addition for charging phones, tablets, or other portable devices, keeping your essential tech powered throughout the day.

Housed in a sturdy composite case with integral clamp storage and a carry handle, the RS1B is built for the rigours of a busy workshop. Its compact design ensures it’s easy to transport and store, while the 0.6m cables offer a practical reach for most applications. Charging is straightforward and safe; the supplied mains charger features automatic power cut-off, preventing overcharging and extending the lifespan of the internal battery. Inbuilt MOSFET circuit protection adds another layer of reliability, ensuring this unit stands up to regular use.

The Sealey RS1B isn't just a jump starter; it's a practical, protected power solution designed to streamline your daily tasks and keep vehicles moving through the bay.
