Sri Lanka uses 230-240V, 50 cycles, alternating current. Over the past decade Sri Lanka has been plagued by power cuts during times of drought when hydropower cannot be generated. However, frequent power failures lasting from several minutes to several hours can occur at normal times, too. The majority of hotels have generators; so most visitors are not unduly inconvenienced. Plugs are generally three or two round pins, but bigger hotels often have three square pin plugs. It’s best to bring a good adaptor with you, but they are available locally. More and more visitors are bringing sensitive electronic equipment to Sri Lanka, such as laptop computers. It is important, however, to bring a voltage stabilizer, for the current does fluctuate, especially in rural areas.
