What does that mean? Is there a switch to go from 100 volts to 110(usa)?
it auto detects mains voltage and switches automatically to match the input voltage.... literally, there's nothing to do other than flipping the plug out, then plugging it in
The packaging says "Worldwide voltage" in Japanese too... they want to make this travel friendly, so in our case, it makes this easy to import and use, without needing a step down transformer
The BQ-CC16 is the same way... it is also auto switching voltage, the euro or UK plugs and be removed by unclipping it, which exposes the US style plug.... you don't need a step up transformer for those either, just plug it in!
