About this product

The Sealey RS102B Roadstart is an emergency jump starter designed to deliver reliable starting power for petrol and diesel vehicles, equipped with additional power supply capabilities for workshop and roadside use. Delivering up to 1500 peak amps of initial starting power, this portable unit is suitable for jump starting vehicles with 6-cylinder petrol engines up to 3.5L and 4-cylinder diesel engines up to 3L, making it ideal for workshop garages, mobile mechanics and fleet maintenance professionals. Built with a durable composite case, the RS102B features integral battery clamp storage and a carry handle for convenient portability between jobs. The front panel displays the internal battery charge level, allowing you to monitor readiness at a glance, whilst an integrated LED worklight provides illumination when working in low-light conditions or at roadside breakdowns. Safety is prioritised with reverse polarity and short circuit protection, complete with an audible warning to prevent connection errors. The inbuilt MOSFET circuit protection safeguards both the unit and the vehicle's electrical system during use. The supplied mains charger incorporates automatic power cut-off to prevent battery damage whilst charging. Beyond emergency starting, this versatile power pack functions as a mobile power supply with two 12V accessory sockets that accept any standard 12V device plug, plus a single 5V 2.4A USB output for charging mobile devices and tablets. The 300A cold cranking amps rating ensures consistent performance, whilst the compact design and 7.8kg weight balance portability with robust power delivery.
