USA travel adaptors: which type do I need?
You should think about what to pack, to guarantee you can utilize your own electrical apparatuses securely while abroad. This regularly incorporates the utilization of a movement connector, which is a gadget that basically enables you to connect any UK electrical apparatus to an outside electrical attachment. Note that it doesn't change over the voltage or recurrence.
For USA there are two associated plug types, types A and B. Plug type A is the plug which has two flat parallel pins and plug type B is the plug which has two flat parallel pins and a grounding pin. USA operates on a 120V supply voltage and 60Hz.
Voltage converters and transformers
Electricity supplies worldwide can vary from anything between 100V and 240V. It can be extremely dangerous to use an electrical appliance that is rated at a voltage different from the supply.
As voltage can differ from country to country, you may need to use a voltage converter or transformer whilst in USA. If the frequency is different, the normal operation of an electrical appliance may also be affected. For example, a 50Hz clock may run faster on a 60Hz electricity supply. Most voltage converters and transformers come supplied with plug adaptors, so you may not need to buy a separate travel adaptor.
All converters and transformers will have a maximum power rating (AMPS or WATTS) so make sure that any appliance you intend to use does not exceed this rating.
Dual voltage rated appliance
You can determine whether you’ll need to use a converter or transformer, by looking at the appliance rating plate.
A double voltage evaluated apparatus will show for instance 'Info: 110-240V' on the body of the machine or its energy supply. This implies you won't require a converter or transformer however only a movement connector, on the grounds that the USA works on a 120V supply voltage, which is inside the 110-240V territory that the double voltage apparatus works on.
Single voltage rated appliances
In the USA the supply voltage is 120V. If the appliance or its power supply are not dual voltage rated, the single voltage appliance will have to be used alongside a voltage transformer or converter to allow the appliance to work safely and properly (unless the appliance operates at 120V).
Converters and transformers perform a similar function, but their applications differ. Converters are typically used with appliances that operate for a short duration (1-2hours), whilst most transformers can be used alongside appliances that operate continuously.
Understand that some movement connectors are not appropriate for any apparatuses that require an earth association. These sorts of movement connectors should just be utilized with twofold protected hardware, which will be unmistakably set apart with the image demonstrated as follows.
