Is the power outlet in Chiang Mai Hotel the same as that in China?

Please see the picture below: Thailand socket looks like American socket, American vertical socket and Thai horizontal socket, and the two-pin part supports both American standard and European standard (Thai standard plug) just like domestic two-pin socket.

The voltage is 220 volts and 50 hertz. So the porcelain two-pin plug can be used directly. If you want to change three hole socket, you can buy a two-ring multifunctional socket on TB 1~2 yuan.
