A:AnswerThis adapter is capable of stepping down the voltage of Nigerian outlets and converting it to 110 volts that US devices typically take. This adapter is capable of adapting the US plug type to Nigerian. Be sure you double check with your device manufacturer to be sure if the devices can be used with adapter/converters.
A:AnswerDo you mean China because thire plugs are the sames as ours. Make sure you get one with the usb plug to. The plug in your photo is from Australia and yes it does that.

A:AnswerIf your C-Pap has a three-prong (grounded) plug (highly likely) you will NOT be able to use this adapter. This adapter is not for use with three-prong grounded US plugs. You will need to find an adapter that will fit a grounded plug or (more likely, as the C-Pap probably is NOT dual voltage, you will need a voltage converter).

A:AnswerThis will depend on the device. If the plug or rating listed on your device says only "120V 60 Hz", then you will need a converter. If you are charging a phone or computer, chances are your plug will list (small printing!) "100-240V 50-60Hz" or "110-220V 50-60Hz". Then it is dual voltage & an adapter is all you will need. This adapter does include a Type F European prong plug.
