Electricity in Sierra Leone is 230v, 50hz. The power supply is not reliable. Electricity fluctuates noticeably, and an Uninterrupted Power Supply, UPS, for your computer and accessories is recommended. When you purchase a UPS, make sure that it is intended for 50 to 60hz, particularly if you plan to run a 110v computer off a transformer.
