Sri Lanka.

230 V · 50 Hz on Type D, Type G, Type M.

Historically a Type D and Type M country — 5 A and 15 A round-pin sockets — with the British Type G increasingly fitted in newer construction. Everything runs at 230 V, 50 Hz. A combined D and G adapter covers nearly every hotel; the big round-pin M mostly serves air conditioners and heavy appliances.

The voltage window

A nominal 230 V supply may legitimately sit anywhere between 207 and 253 V (±10%). Dual-voltage gear (marked 100–240 V) shrugs at all of it.

Pack an adapter — Sri Lanka runs 230 V 50 Hz on Type D, Type G, Type M — and your 120 V appliances need to be dual-voltage or transformed, adapter or not.
