A Type A plug in Saint Kitts and Nevis?
Yes — it seats, though without a guaranteed earth.
Saint Kitts and Nevis's Type G and Type D and Type A and Type B sockets accept a Type A plug (US two-blade (NEMA 1-15)). The plug is unearthed by design, so nothing is lost in translation. The wall delivers 230 V at 60 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.
