Why do shaver sockets accommodate round pin plugs in the 115V outlet when countries with 100V to 120V mains supplies use type A plugs with flat pins? Is there a country somewhere with a 100V to 120V mains supply that just so happens to use shavers with round pin plugs?
Just for information, there was a case a while ago where a shaver socket had been used to re-charge an electric toothbrush but the transformer had overheated despite the toothbrush charger drawing less current than a typical shaver. The socket manufacturer's defence was that the device was clearly marked 'shavers only' and it was the long-duration nature of the load that had caused the issue - the nominal shaver socket VA rating being only valid for the short duration typically needed for a shave. I suppose that's similar to the 'tool rating' of CTE site transformers - the continuous rating being far lower.
Experience has revealed that shaver sockets can get quite hot if used for prolonged periods powering computers. There is no ventilation to enable the transformer to cool by convection, but the transformers are probably physically too small or made of too lossy materials to sustain continuous loads without getting hot. Some makes probably get hotter than others with the same load and metal fronted sockets might fare better than plastic sockets.
