Strictly avoid inserting a 110V – 120V appliance (E.g. hairdryer) into a Sri Lankan 240V plug base; you might find it catching fire in your hands!
Sri Lankan hotels have two types of plug bases; either the UK (Type G) or India (Type D). *Do not confuse with the larger 15 Amp plug which is used for ‘heavy duty’ appliances like air-conditioners, and microwave ovens.
The voltage is Sri Lanka is 220 / 240 volts.
