Yeah its closer tot eh uk but different in america spni usually avoid buying chinese electrical thingsSorry, i read it that you were saying China has different electrical things, like, electricity has its own set of physical laws in China lol. But generally, no.. they'll likely also follow suit with 1 watt per litre.
They'll have slightly different voltage and frequency (Hz) .. I think they're compatible with the UK (50Hz) but not US (60Hz)
