Traveling in Ireland - NO PC to charge my Fuze

Do I need a CONVERTER and an adapter, or will a simple adapter work with a USB charger for my Fuze??  Going to be in Ireland.

Look at the USB charger to see whether it accepts US voltage (110) or more (110-220).  You need to get a charger than can handle international voltage (and shamrocks) with a USB jack output. Then plug your Fuze cord into that.
