I can't get the site to work (check the URL
), but the information leads me to believe that there is a transformer included as there is two parts to the information.
For example, the first part says AC100V, then later on DC5V. I'm almost certain this is saying that the input is 100V to the transformer, but the device itself uses DC5V at 1.2A.
Quite simply all you need is one of those "multi-adaptors". They are quite cheap from the likes of Argos / Maplin / Ect... with the correct connector and the ability to supply that voltage / amps.
They will be adjustable so you can change it depending on device
