VIETNAM/SOUTH KOREA - Both these countries have the exact three different types of outlets in them. This special Type E (C/F) will work in 2 of the 3 so this is an excellent choice since it covers all the outlets and you could need both of these types of plug adapters. RELIABLE, DUAL- Both have dual inputs. This CE Certified and RoHS Compliant UNIVERSAL ADAPTER - This universal input will fit plugs in every country except Lesotho and Swaziland. Adapter plugs do not convert voltage, but necessary to adapt to correct outlet. You may need additional voltage converter with the adapter to power your device (hair dryer, ipad, iphone, laptop computer, coffee machine, electronics, etc...) if it does not have dual voltage options.
