I refer the honerable gentleman to the answer that Paul has put up today! Your mobile charger will change the mains to a low voltage DC power - as there is no problem then it's just a conversion to low voltage, rectify to DC, and smooth out the pulses. I assume the tootbrush is the type that doesn't actaully connect just sits in the holder that's plugged in the mains - I think that would need a true sine wave to transmit the power properly.
