Sealey SL34S Lithium Jump Starter Power Pack

The Sealey SL34S is a lithium-ion jump starter power pack designed for 12V and 24V vehicles, delivering a peak output of 2500A in a compact, lightweight unit.

Weighing just 2.6kg, this portable jump starter is well suited to professional tradespeople, fleet operators, and breakdown technicians who need reliable emergency starting capability on the go. It is capable of starting vehicles up to 350hp and features a force start function that enables boosting of deeply discharged batteries down to 0 volts — a significant advantage when dealing with completely flat batteries in the field.

Beyond jump starting, the SL34S doubles as a multi-purpose power bank, equipped with dual USB outputs (5V/1A and 5V/2.4A) to charge phones, tablets, and laptops. A built-in 1W worklight with three settings adds further utility in low-light conditions, making this a versatile addition to any van kit or workshop.

The unit is fully protected against reverse charging and overload, and includes a 4-stage LED battery level indicator so you always know the remaining capacity. It is supplied with both a mains charger and a USB charging lead.
