Most outlets in the United States accept Type A (two flat blades) and Type B (two flat blades plus a round ground pin). The adapter you choose should convert your plug to one of those shapes.

• Plug types: Match your device’s plug to a Type A or B adapter.
• Grounding: If your device has a three-prong plug, use a grounded adapter that ends in Type B.
• Voltage: US power is about 120 V at 60 Hz. Adapters change plug shape only; they do not change voltage.
• Features: Consider options like built-in fuses, USB ports, and foldable prongs for travel convenience.

Check your device label for a wide input range such as 100 to 240 V. If not, a voltage converter may be helpful.

European plugs are typically Type C, E, or F with two round pins, so you’ll need an adapter that accepts those and outputs to Type A or B for US outlets.

1. Check voltage: If your device lists 100 to 240 V and 50/60 Hz, a simple plug adapter is often enough.
2. If single-voltage: Devices labeled 220 to 240 V only may require a step-down converter to work with US 120 V power.
3. Grounding matters: If your plug has earthing contacts, use a grounded adapter to a Type B outlet.
4. Fit and safety: Do not force plugs. Choose adapters with safety shutters or fuses when possible.

Small electronics like phone chargers are commonly dual-voltage, but always confirm on the device label.

A Type C plug has two round pins and no ground pin. It’s a slim, ungrounded plug commonly seen on many chargers and small appliances outside North America.

• Shape: Two round pins, close together, on a compact body.
• Grounding: No third pin, so it’s ungrounded.
• In the USA: It won’t fit US outlets directly. You’d use a C-to-A or C-to-B adapter to plug into American sockets.
• Voltage note: A plug adapter changes shape only. If your Type C device is not dual-voltage, pairing with a suitable converter may be necessary.

Check the power label on your device to confirm voltage compatibility before choosing an adapter.

Hair dryers draw high wattage, so you’ll want to check both the plug type and voltage before using one in the United States.

1. Read the label: If it’s dual-voltage (for example, a switch for 120/240 V), set it to the appropriate voltage and use a plug adapter to Type A or B.
2. If single-voltage: A 220–240 V-only dryer may need a step-down converter sized for the dryer’s wattage. Some converters are not intended for continuous or high-watt use.
3. Grounding: If your dryer has a three-prong plug, use a grounded adapter to a Type B outlet.
4. Safety: Do not exceed converter ratings and allow for ventilation.

When available, using a local or dual-voltage dryer can be simpler.

A quick label check can clarify whether you need a voltage converter or just a plug adapter for US outlets.

• Look for voltage range: If the device says 100–240 V and 50/60 Hz, it typically works worldwide with the right plug adapter only.
• Single-voltage devices: If it lists one range (for example, 220–240 V), you may need a step-down converter to use it on US 120 V power.
• Match wattage: Ensure any converter’s wattage rating meets or exceeds your device’s draw, especially for heat tools and appliances.
• Consider use time: Some converters are better for short-term use, not continuous operation.

When uncertain, choosing devices designed for US voltage can help simplify setup.
