No adaptor with you and already abroad? You’re not out of options — many airports and local shops sell them. Still, bringing your own is the simplest way to avoid paying over the odds or ending up with something that barely works.
Rio de Janeiro is often part of a trip that also includes Argentina and Uruguay. Worth checking the adaptor info — plug types can vary between South American countries.
Do You Need a Voltage Converter?
Don’t assume your gadgets will work straight away in Rio de Janeiro — the voltage isn’t the same as our 230 V, so a converter may be required.
Always check the voltage label before plugging in abroad; if it reads ‘100–240 V, 50/60 Hz’, your device will usually work without a converter.
