About this product

The Sealey RS105B Roadstart is a professional-grade emergency jump starter designed for rapid vehicle recovery across both 12V and 24V systems. Delivering up to 3100 peak amps of starting power, this versatile roadside assistance tool is suitable for starting 12V vehicles with 8-cylinder petrol engines up to 6L and 8-cylinder diesel engines up to 4.8L, making it ideal for garages, mobile mechanics, fleet operators and breakdown services. The unit also handles 24V applications, managing 6-cylinder petrol engines up to 3.5L and 6-cylinder diesel engines up to 3L with 1550 peak amps. Its robust composite case features integral battery clamp storage and a carry handle for convenient transport between jobs, whilst the front panel displays the internal battery charge level to prevent unexpected power loss during critical operations. Safety features include reverse polarity and short circuit protection, plus an inbuilt fuseable link protection system to safeguard both the unit and the vehicle being started. The supplied mains charger incorporates automatic power cut-off to prevent battery damage during charging cycles. An integral LED worklight provides illumination for roadside emergencies or workshop use, whilst two 12V accessory sockets enable the unit to function as a portable power supply for compatible 12V devices.
