Vietnamese power outlets

Apparently, the (english-speaking) internet doesn't seem to be sure how power plugs in Vietnam look like. So, I was taking account when I went there.

I found two types of power plugs: the Euro-style "double-round-hole" design, and the "compatible with England/USA" layout pictured above. As for voltage, even the smallest village along the coast provided 220V - not a single outlet was rated for 110V.
