Choose a jump starter by its starting current in amps rather than by milliamp-hours: the Lokithor J401 delivers 2500 A and the J5000 PRO 5000 A, and that is what decides how big an engine the device can still turn over. Some models are multi-purpose — they also work as a power bank, a torch, a tyre compressor or even a pressure washer. In the cold season it pays to look at the stated operating temperature: the J401X is described as working even at –40 °C.
