Auto Express Car Reviews

An unbeatable combination of price and performance from Clarke. The maker reckons these monsters will start petrol engines of up to 7.0 litres, thanks to the 500-amp capacity and 35mm cable.
Our tests show they spun our test engine more quickly than any other leads here, and with minimal heat build-up. We also liked the boot-friendly zip bag, and well sprung fully insulated clamps. An easy winner.
