Bring a Types A and B adapter (or a universal one that covers both).
Voltage
Varies
Brazil 127 V / 220 V → the United States 120 V. Check the socket and your device label.
Frequency
Same
60 Hz → 60 Hz.
Your plug, their socket
does not fit
In Brazil: Voltage depends on the state and city: 127 V in much of the south-east (including São Paulo and Rio de Janeiro) and 220 V in the north-east and Brasília. Check the label on the socket or ask your host.
Your devices in the United States
Look for the “INPUT” line on the charger or label. A range such as 100–240V ~ 50/60Hz means the device adapts by itself and needs only a plug adapter.
| Device | Usually | In the United States |
|---|---|---|
| Phone, tablet and laptop chargers | 100–240 V | Plug adapter only |
| Camera and power-bank chargers, e-readers | 100–240 V | Plug adapter only |
| Electric shavers, toothbrushes | often 100–240 V; check | Check the label and the socket |
| Hair dryers, straighteners, curling irons | single voltage | Check the socket voltage first |
| Kettles, irons, travel cookers | single voltage, high power | Check the socket voltage first |
