This is a handy device that is designed to convert a two pin European Schuko plug to a three pin UK plug. It is simply a plug type adapter and does not convert any voltage. It saves having to chop a moulded European Schuko plug off a cable and rewire the cable with a UK plug. Using a product like this is quicker and safer, as many people do not have experience of wiring up mains plugs these days. The only tool needed is a screwdriver. The adapter is an SCP3 model from a British company called PowerConnections and is manufactured in China. It is reassuring to see it is marked with the British Standards Kitemark.
It is made from good quality black plastic, with brass sockets and pins. On the outside there is a compartment containing a 13A fuse. To use the adapter, the hinged top cover is opened and a Schuko plug is carefully plugged in (upside down), and then the cover is closed. Care must be take here to ensure the lip of the top shell mates well with the lower shell. Two self tapping screws are then used to secure the two halves together. The result is a quite large UK plug that almost resembles a wall mounted power supply. The power cable emerges at right angles to the adapter, so it should fit onto cramped power extension strips with ease. On giving the Shuko plug a test wiggle in the adapter, it can slide up and down slightly which I suppose is due to the adapter being designed for plugs of slightly different sizes. I do not think it could be pulled out easily, so the end result seems sturdy and safe.
Overall, this seems to be a well designed and good quality item that will make life a lot easier for someone who wants to start using their new gadgets from Thomann and not wire plugs.
