120 Volt Plug Adapter
The 120 volt plug enables customers to plug 120 volt items (North America) into Korea outlets 220 volts. Warning: plug adapters do not convert power, and should only be used with items that have a built in power transformer (ie. laptop computers). For more information, please read below.
Electrical Power & Voltage in South Korea
South Korea functions on 220 volt electricity. The outlets are round, and equipped to accept a plug with two round prongs about 2 cm apart, like these:
Items with built in transformers, or that are designed for 220 volt electricity
Some electronics have power transformers built in to them (ie. most laptops, some battery chargers). Such items only need a plug adapter to function properly if the user is coming from a country with different plug shapes. An adapter simply allows the user to plug the device into a different socket type. Please see the adapter chart below to see which TAS adapter is right for you.
Items that do not have a built in transformer, and are designed for different voltage electricity:
Other items do not have built in transformers and actually need to a device that will convert the power from one voltage to another (ie. 220 Korea to 120 North America). Universal adapters from stores like the Mac Store or Radio Shack are expensive and usually do not have the capability to power items that use any significant amount of power (ie. hair dryers or game consoles). Plugging a device into the wrong voltage without a power transformer will damage the item and is a major fire hazard. TheArrivalStore.com provides the power transformers and adapters you need at a price that will not break the bank.
In order to find the correct model transformer necessary check the following criteria:
-Does the device have a built in power transformer?
For example most laptop computers have a built in transformer.
A quick guideline to see whether the device has a transformer, is to check and see if there is a box on the cord between the device and the wall. These boxes are typical transformers and a description of the voltage conversion capabilities should be listed on the bottom of the device. If the device does have a transformer with the appropriate voltage conversion, it is most likely that only a plug adapter is necessary for the device to function appropriately.
Note: the plug adapters do not have the ability to protect your item against power surges or irregular power. A power converter does regulate the power somewhat and provides mild protection against surges.
If your item is valuable, to be safe, consider bringing a surge protector (power bar/strip) from your home country and plugging the power strip into a 1 KVA or 3KVA transformer. This is a safe way to protect your expensive items.
-How many watts/volts does the item require?
This information is usually listed on the manufacturer's label on the bottom of the device or in the owner's manual. To be safe, TAS recommends that the power transformer is at least 50% higher than your device because some items require a transformer that has 2-3 times the watts the device is rated for when turning-on.
How to convert from watts to volts:
Simply divide the watts the items use compared to your home power voltage.
Watts = volts (your home country’s voltage) x amps
With all of this conversion stuff, the bottom line, is just better to be safe vs. sorry
Remember that a higher watts rated transformer will never hurt your device but one that is not powerful enough will not work and will most likely damage your device and the transformer.
