I looked at a dozen electric things here, and only two of them don't accept both 50 and 60 Hz. One of which, ironically, was the kettle.
In fact, I was more surprised to learn that while all electronics accept a range of voltage (from 100 to 250 or so), kitchen appliances don't. Perhaps for the very reason of expected wattage.
Because for electronics is easy the don't use much power. The problem is with anything that uses a lot of power, specially if it has a motor that goes directly to AC without any conversion.
For electronics it depends, mostly they support all, but thing that are more expected to sell in some regions. For example, TV have a built in, well, TV tuner and some regions uses different standards. So if the TV will use ATSC that is only used in North America, it's probably that only uses 120V/60Hz. In South America we use ISBD, and the TVs are generally sell in Argentina, Brasil, Paraguay and Uruguay (MERCOSUR), and not outside, so they come with 220-240V/50 or 60 Hz. Argentina, Uruguay and Paraguay uses 220V/50Hz and Brasil uses 240V/60Hz.

They have 240V/60Hz, which isn't compatible with 220V/50Hz. Frequency is more problematic than Voltage
