Draper 12v Power Pack with Air Compressor 40134
It was tight at the top, with this Draper and the Clarke just missing out on the podium.
The 40134 was one of the biggest products on test, but it’s not too heavy to carry despite packing a compressor in the slender casing.
We liked the isolator and wrong polarity alerts, but while the light is better than nothing, it’s weak.
Leads are a bit short, although the clamps have usefully large jaws.
