I am going to the UK and want to charge my phone while there (I know I can't use the phone there but can see all my info if its charged). I bought a Dynex INternational Traver Adapter for Portable Electronic Devices from Best Buy recommended by Verizon but my question is - do I need a converter too? to convert volts from 220 to 110? I have a converter but it warns not to use it wtih with products containing electronic circuity, e.g. computers and digital products. So my problem is that I think I need a converter too so I don't fry my phone and I have called HTC, Dynex and Verizon and nobody can give me a clear answer, the User Manual does not address this either (all 390 pages of it!)
