Travel adapter for Sri Lanka and is power surge protection really needed

Sri Lanka officially uses TYPE D and TYPE G sockets (the Indian three-round-pin Type D and the UK three-rectangular-pin Type G). In practice, modern hotels almost universally have Type G now, while older guesthouses and rural places may still have Type D, and many sockets are "universal" accepting both. So a UK-style plug works most places, a Type D adapter is useful for backup, and the cheap "world traveler" adapters cover both. Voltage is 230V 50Hz - same as Europe and UK, so no transformer needed. POWER SURGE QUESTION: Sri Lankas electricity grid has improved a lot but still has occasional brief brownouts and the rare lightning surge during heavy monsoon storms. For a laptop and camera batteries, modern chargers are surge-resilient to a reasonable degree and a separate surge protector is over-engineering for a normal trip. But if you are bringing expensive professional gear (cinema camera, dedicated audio kit), a small travel surge protector is cheap insurance. UPS not necessary for personal use.
