I'm bringing the 3 prong plug w/me to Ireland but will I need a voltage adaptor too?
Look on your charger plug. 99% it says 100-240 V, 50-60 Hz. Then you just need a plug adaptor.
There is no such thing as a "voltage adapter". Technically, they are voltage converters (they convert the voltage, for example, from 230V to 115V. A plug adapter is a mechanical device with one side accepting your US plug and the other side to plug into the receptacle in Europe. Rick sells one for the UK. It doesn't show the side for a US plug, but since the grounding pin on the UK side is metallic, I assume the opposite side accepts the third (grounding) US (round) pin.
I don't think I've ever seen a cell phone charger with a grounding (3 prong) plug.
I'm not going to go over familiar ground about the difference between adaptors and converters.
But I will add this.
On my recent trip to Ireland I needed to recharge my IPad and a simple converter would not have been possible to do the job for my electronics. Fortunately, my unit had a USB port. The only outlet available for recharge would not allow me to plug my device in normally.
Thank you all for the info. I did ck my Apple charger and it is 100-240V and 50-60Hz. I have a 3 prong outlet specified for Ireland so I should be fine. Thanks again.
