Hi I recently bought an electronic device from the USA. It came with an American plug. It is only 7.5 watts. I live in the UK so I need a step down transformer and plug adapter to enable me to plug it in over here. I bought a transformer to do this but my device still doesn't work. The only thing I can think of (besides faulty equipment) is that there is a problem because the device I'm trying to plug in has a 2 pin American plug but the adapter has a 3 pin socket. I was wondering if people know whether you can just plug 2 pin American plugs into 3 pin plug sockets. I presume so but I have a problem. Any suggestions welcome. Thanks.
