Sealey RoadStart RS4000 Emergency Jump Starter Power Pack

The Sealey RoadStart RS4000 is a high-capacity emergency jump starter power pack designed to get vehicles moving again when a battery fails — with no second vehicle required.

Built around a 32,000mAh lithium-ion battery, the RS4000 delivers an impressive 4000A peak current and 2000A cranking current, making it capable of starting petrol engines up to 12 litres and diesel engines up to 10 litres. This makes it well suited to a wide range of vehicles, from cars and vans to larger commercial and agricultural vehicles.

Despite its capability, the unit is compact and lightweight enough to store in a glove box or backpack, making it an ideal addition to any service vehicle, fleet operator's toolkit, or roadside emergency kit. Built-in protections against short circuit, overload, and reverse polarity add a further layer of confidence when connecting to an unfamiliar vehicle.

Beyond jump starting, the RS4000 doubles as a multi-purpose power bank, capable of delivering several full charges to smartphones, tablets, and laptops via its USB Type-A and USB Type-C outputs. An integral LED flashlight with solid, SOS, and flash modes adds genuine roadside utility. The unit is supplied complete in a hard-shell zip-up carry case with battery clamps and two USB cables.
