For those of you who going to buy 220V. Be warn. Expect to source other power adapter as given one written on the adapter input source 240V 60hz. They supposed to and we expect the power supply adapter to be 100~240V 50~60hz range as now a day is common but they simply ignored the safety and risk of buyer (House caught fire) simply sale it without this consent. Already ask whether it could be use with 230V 50hz input but no one from massdrop who selling this want to answer my question.

Thanks for sharing this. My country's main is 230v 50Hz, and the step-down adapter I got for the O2 is rated 240v 60Hz.
According to this article there may be heat issues. "A transformer designed specifically for 240V at 60 Hz must not be driven with more than 240×50/60 = 200V at 50 Hz. " "resulting in excessive current that can overheat and destroy the transformer. "

Mine does get somewhat warm, but not hot. However, I've been unplugging it when not in use, just in case.
