I need some help from someone more technically minded than me. I am looking to order the 2170 system direct from Japan to the UK, I am having trouble working out which transformer I need, I'm assuming I need a step up transformer from 100v to 230 but I am unsure of the wattage rating? It seems the energiser is 100w with a max output of 280w is that correct? So a transformer rated at 300w should be ok? Thanks in advance if you can help.
You'll actually be much better served by getting a 12vDC power supply locally for your local AC, rather than try to convert from your local voltage to the 100vAC used in Japan. I grabbed a 12vDC 1A wall wart I had lying around and it works great.
Couple things to note:
1: some switching wall warts can be a little noisy; some can be A LOT noisy. So get a good one. Or get a regulated supply (aka linear) and be done with it. Over sizing the current (amps) will make it a little less noisy. (I'm using a switcher from an old NetGear router and my tinnitus ears can't hear any noise.)
2: the Amp that comes with the 2170 uses a reverse polarity power connector! That is, positive is on the outside of the barrel plug, negative on the inside. This is backwards from most power supplies. If you can't find one that's already reverse, then you can get a normal one, cut the cable, reverse the wires, and solder then tape/heat shrink them to cover them back up. Then, ya know, clearly Mark it so you don't use it somewhere else and blow up the other device.
