Has anyone got the subject kit and any opinions as I'm tempted by the current deals on offer. I've currently got the Mk1 version and am very pleased with as it does what I want it to do (mostly boiling a 1Kw kettle when I'm off EHU!) but I've got to say that I'm attracted by the faster charging potential of the Mk2. I note that the 'surge power' is 2Kw in my current unit but 1.5Kw in the Mk2 - does that make any difference in the real world (ie. boiling my 1Kw kettle)? What about the competition?
