|In my opinion only 2 things are of consideration when comparing jump leads: The current flow - the higher the amps the more & quicker the current flows. Length of cable - short cables are inconvenient
We dont bother selling the really piddly leads found in some spares shops - they take a long time to pass a charge and sometimes dont work at all on larger vehicles with dead flat batteries. And they sometimes get hot.
Personally I dont think even the 200amp ones are much good, but people keep asking for them so I sell them.
