Do I have to change the plug to go to America?

To go to the United States, you need to change the plug for the following reasons:

1, voltage difference: American socket voltage is 1 10V, and Chinese socket voltage is 220V.

2. The three-level plug is different: the commonly used three-pole plug in China is three vertical and three flat, while the most commonly used three-pole plug in the United States is one round and two flat, with round ground wire and flat zero fire wire.
