Halfords Jump Starter 677444 Advanced Lithium LED Light Portable Up to 2L

Instead of connecting jump leads or lugging a heavy old-fashioned jump starter out of the garage, portable jump starters with powerful lithium batteries have quickly become the go-to method of starting a car with a dead battery. At their smallest, these starters are around the size of a large power bank – the kind of device you’d normally use to charge up a smartphone – yet have the power to restart your car. Many of the best jump starters also have USB ports or charging up other devices, and an integrated LED torch to help you out in the dark. For this review, we have the Halfords Advanced Lithium Jump Starter, and specifically, this is the model designed to work with petrol and diesel engines up to two litres in capacity.
