Electrical outlets in Thailand are charged to 220v at 50 cycles per second, which is compatible with appliances from the U.K. but not those from the US and many other nations. While most computer cables have adaptors for voltage, visitors from the U.S. and those not on the 220/50 v. will have to bring adapters to run most other appliances. Outlets in Thailand generally feature flat, two pronged plugs, though some feature holes for round plug ends. Few outlets feature three holes (grounded outlets) so it is often necessary to have a three to two prong adapter for using notebook computers in Thailand.
