A pretty sweet design to minimise the space required to transport the standard UK 3 pin plug, the device folds up to a height of less than 1cm and is simple to fold out to be used. The video below demo’s this, shows how it’s put together and also shows a design for a multi-adapter which also takes up much less space than the current ones.

I’m curious as to whether or not this meets any required electrical and safety standards in the UK, but in all would love to use these.
