I always try to avoid the recon units personaly, I just don\'t trust them. Lot\'s of people have good edxperiences with them, I just don\'t like the idea. As for the power issue, no, an American power supply will NOT work in the UK. However you have 2 very good options.
1. The make travel converters that will drop it down to the 110v that we use.
OR
2. You can go to Radio Shakc or whatever electronics store you have and get any old 5v 2a powersupply that will fit in the hole. IT\'s a standard plug, so it shouldn\'t be hard to find.
