A US plug travel adapter is a compact device that allows you to connect electrical devices with different plug types into US‑style outlets (Type A or B). It doesn’t convert voltage—only the plug shape—so your device must be compatible (typically 110‑120 V). Ideal for travelers coming to or going to regions using US outlets, letting them use their own chargers safely when paired with devices that support the local voltage (or with a voltage converter if needed).
