DBPower DJS10

Best price: £39.99

The stylish capsule case housed a well designed, compact device. It felt solid, and although the jump leads seemed a bit on the cheap side, they proved easy enough to use. The instructions were clear, as was the table for checking whether your vehicle is suitable. This device promises 1,000 jumps on its lifecycle, and each time the battery goes flat, it takes five hours to recharge. Up there with the best for value, but given how small it is – the charger is similar in size to an external hard drive for a PC – it’s not packaged as compact as it could be.
