Will my plug fit?
Say where you live and where you're going. The answer is one line.
The sockets
Will mine fit?
United States to Vietnam
Your phone charger is fine.
Your Type A plugs go in as they are. Your Type B plugs won't, and those are the earthed ones: a hairdryer, a heavier laptop brick. Pack an adapter only if one is coming with you.

One thing first. Nearly every phone and laptop charger takes 100-240 V. If yours says so, you need a plug adapter and not a voltage converter.
Vietnam: 220 V. United States: 120 V. A charger marked 100-240 V won't notice, and a kettle will.
