A Type G plug in Brazil?
Not directly — pack an adapter.
Brazil's Type N / Type C sockets don't take a Type G plug. A plug adapter solves the shape problem — it changes pins, not electricity. The wall delivers 127/220 V at 60 Hz (114–140 or 198–242 V within tolerance) — if your device isn't rated for that (look for "100–240 V" on the brick), an adapter won't save it.
