This grounded type I plug adapter with two outlets could be widely used in Australia, New Zealand, China, Cook Islands, Fiji, Argentina etc.
The 2-in-1 feature is a excellent way to share the outlet. It's very a very favorable feature when there's just one outlet.
The adapter accept a wide variety of two and three prong plugs.
Please Note that your Device need to support 100-240V in order to use with this adapter when you traveling overseas.
This adapter is plug adapter, NOT voltage converter.
