110V AC can be enough to contract your muscles involuntarily, so if you get unlucky you may find yourself unable to let go. It's definitely safer, but still not safe. > Are there any downsides for using 110v instead of 220v? Not really, except that most appliances will only use 110v instead of 220v, because most power outlets are 110v with a few special 220v outlets set up specifically for heavier appliances. Usually 110v is perfectly adequate anyway, but electric kettles in America are slower.
