A flat battery can leave a motorcycle or car stranded, and finding a second vehicle for a jump start is not always practical. The Clarke JS1224 2000A 12/24V Jumpstart is a standalone starter for vehicles using either 12V or 24V electrical systems. It uses two 22Ah batteries and weighs 16kg. The review gives its current price as £215.98.

The unit combines a compact, rugged design with a tough plastic case, built-in charging cables, simple controls and a large carrying handle. The cables are one metre long. To start a vehicle, the unit is placed beside its battery, connected to the correct terminals, set to 12V or 24V using the rear selector dial and switched on. The review states that the cables deliver up to 1000A at 12V or 500A at 24V.

Features and verdict

Its equipment includes a built-in five-bulb work light for use in darkness, an audible warning for incorrect connections and a low-battery alarm. A 12V DC outlet can power electrical devices while on the move. When it is not being used, the jump starter can be recharged from mains electricity or an auxiliary 12V supply with the supplied adaptors.

The review describes the Clarke as effective, well designed, rugged and good value. It presents the JS1224 as Machine Mart’s best-selling example and says the retailer’s website carries virtually universal five-star reviews. A customer identified as John praises its performance and price, while also describing the delivery process as quick and easy. The stated price and retailer-review picture belong to the review’s snapshot and may change over time.
