A Type G plug in Cambodia?
Yes — it seats, earth and all.
Cambodia's Type A and Type C and Type G sockets accept a Type G plug (British 13 A plug). Both sides carry an earth, so grounded appliances keep their protection. 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.
