Please be aware that whilst a travel adaptor will allow you to physically plug a UK plug into a different socket it will not change the voltage or frequency of the supply.
Voltage - We do not have any information about the voltage / voltages in use in Sao Tome and Principe. You should check locally what the voltage is. UK appliances will generally operate satisfactorily with a voltage anywhere in the range 220V - 250V. If the local voltage is in the range 100V - 127V you will need to check your appliance for compatibility. Some appliances are marked 100 - 240V either on the equipment itself or the power supply (if it has one). If it is not marked as able to accept the local voltage do not plug it in! In order to operate incompatible appliances you will need a transformer.
Frequency - We do not have any information about the frequencies in use in Sao Tome and Principe. The UK operates at 50 Hz so if the area that you are travelling to runs at this frequency it will not cause any issues. If the area that you are going to operates at 60 Hz it makes little practical difference as most travel appliances will run at either frequency. Some items with motors, such as hairdryers and some clocks will run a little faster than intended but it is not likely to be problematic. Check your device - it may say 50/60 Hz which indicates that it is compatible with either frequency. If you are in doubt or have expensive equipment check with the manufacturer first as some equipment may be damaged by running on an incorrect frequency.Need another travel adaptor? Search by Country
