Electric Power and phones

See FAQ tip: https://www.ricksteves.com/travel-tips/phones-tech/electric-adapters-converters

If you see a range of voltages printed on the item or its plug (such
as “110–220”), you’re OK in Europe.

A small electrical adapter allows American-style plugs (two flat
prongs) to fit into British or Irish outlets (which take three
rectangular prongs)....

Typical electronic devices will be rated for 110-240 vdc 50/60 Hz input and will output 5+ vdc (depending on the device) at the appropriate amperage.

thanks, but my phone doesn't have anything written on it. So I guess to be safe I'll have to use the converter.

lynncapurro, it will say it on the charger, not the phone itself.

Have never used a converter with my various Apple phones. Remember, these devices are sold all over the world. If you can't find this on the charger look it up on the Internet. Maybe one less thing to pack.

Here is a link to Apple's power adapters: http://www.apple.com/power-adapters/
The link has images of the certification labels defining their input and output ratings. All devices should have a similar certification label. Look for input rating and as said, verify that it is rated for 110-240 vac or a wider range and 50/60 Hz. UK power will typically be delivered at 230 vac 50 Hz.

RE: Have never used a converter with my various Apple phones.
In a sense every Apple portable device has a power converter. The power converter "adapts" alternating line power input at 110-240 volts alternating (50 or 60 Hz) and out puts the electricity at 5+ volts direct current to power the device or the device's battery charger.

thanks everyone, I spoke to my phone company and my LGK10 does not need a converter just an adaptor. I hope this helps someone else.

Yes these days I think you would be hard pressed to find a phone that did need a converter.
