USA runs at a 120V voltage supply and 60Hz frequency. Keeping this in mind, it becomes essential to carry all the relevant electrical appliances, to avoid any last-minute problems. We bring you, some of the relevant piece of information about the types of adapters you need to pack up, before boarding your flights to U.S.A:
- It is a device that allows one to plug-in any of the UK electrical appliance/appliances into another/foreign electrical socket/sockets. A point worth noting here is that it is NOT a voltage/frequency convertor. In USA, there are 2 types of associated plugs:
• Type A
- It is the plug that has 2 flat parallel pins
• Type B
- It is the plug, that has 2 flat parallel pins + 1 Ground pins.
- Sudden frequency/voltage changes can temporarily/permanently damage your electrical appliance. Since, most of the voltage/frequency converters/transformers are usually coupled with plug adaptors, one need not buy a separate travel adaptor.
Dual-Voltage Rated Appliance
- Since USA runs on a 120V voltage supply which lies within the 110-240V range of a dual voltage appliance, so carrying a travel adapter would be enough in U.S.A.
Single-Voltage Rated Appliance
- A single voltage appliance must be used along with a voltage converter/transformer, so that it can work properly and safely (unless it runs at 120V). Point to be noted here is that some of the travel adaptors are unsuitable for the appliances that need an earth connection. The above-mentioned travel adaptors are supposed to be used only with a double insulated equipment.
