via bsag, I think this slimline plug is an absolutely fantastic idea.

UK 3-pin plugs are pretty sturdy, but if you’re carrying a couple of power cords around – or phone chargers, laptop power bricks etc. – then you quickly become aware of how bulky they are too.

The design of the slimline plug is aimed at getting round that, and seems to work really well. Even better are the adapters that allow three or four slimline plugs to be used in a space similar to that of a normal three-pin plug.
