A:Answer The charger that came with mine is quite universal: 100 - 240 volts, 50, 60 hz. You will still almost certainly need an adapter in Europe or the U.K., not because of the voltage but because the plugs are different. We found a collection of four or five plug adapters for less than $10 at a travel store but that’s all they are, just plug adapters; they do NOT change the voltage, even thought the sales clerk told us that she had been advising customers that they do! Most power supplies these days can tolerate a large range of voltages - you have to read what is actually engraved on the adapter itself.
