Sealey RS1.V3
Price: £99.95 Jump lead length: 0.60m
At first glance, this seems a well designed unit. The shape and top handle make it easy to carry, and the charge indicator on the front panel is simple to follow. Sealey claims a peak output of 1,000 amps, but this didn't translate into anything special on our test car. Price seems excessive for a unit with no isolator, compressor or light.
