Traveling abroad you’ll likely encounter many different outlets. While most of our stuff uses an adapter that will take any local power supply from 100volts to 240volts, the plug shapes are still different. Usually you buy a way over-priced adapter for a specific region before heading out.
Not in China! In Shenzhen most wall outlets and power strips use this amazing universal socket. It accepts US/Japan/China style blades, Australia’s slanty blades, European pins, UK/Hong Kong bulky crazy slugs, and probably some others. I like to think this evolved because appliances made by Chinese OEMs have whatever plug a foreign company ordered and the Chinese adopted this socket to accommodate the general randomness of the stuff available.
This particular outlet is in a “tower” power strip currently popular in Huaqiangbei. It also has 4 USB ports capable of 2.1A (so it claims…) for charging as well. A tower with 16 plugs ran me 60RMB (~$10USD).
P.S. Local voltage is 220AC/50Hz in Shenzhen, China.
