A Type D plug in Saint Vincent and the Grenadines?
Not directly — pack an adapter.
Saint Vincent and the Grenadines's Type G / Type A / Type C / Type E / Type I / Type K sockets don't take a Type D plug. A plug adapter solves the shape problem — it changes pins, not electricity. The wall delivers 230 V at 50 Hz (207–253 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.
