Can I Use My Laptop Charger in United States?

Q: What plug type does United States use?

United States uses Type A/B sockets at 120V / 60Hz.

Based on what's typical for this device — confirm on the label to be sure.

Typical profile: Your laptop charger can work in United States if its actual input rating, frequency and plug match the local supply.

Conditional compatibility

Use directly only if your actual input rating covers the local voltage and frequency and your plug fits with any required grounding. A typical category profile does not confirm your own unit.

Why

Use directly only if your actual input rating covers the local voltage and frequency and your plug fits with any required grounding. A typical category profile does not confirm your own unit. The cited Dell adapter accepts 100–240V, 50–60Hz, but one model does not verify every laptop supply. Read the actual INPUT label and preserve any required grounding. A voltage converter is unnecessary only when the full local voltage and frequency are covered and the manufacturer permits use.

United States runs 120⁠V / 60⁠Hz. Standard 120V at 60Hz. Type A is ungrounded (two flat blades); Type B adds a round ground pin. A single-voltage 220–240V appliance brought from Europe or Asia will run at roughly a quarter power or fail to start here — but it will not burn out.

Conditional Dell guidance, not a no-earth claim for all laptop chargers.
Dell: 16S 65 W USB-C power adapter specifications: Power adapter, Table 1: 100-240 V AC, 50-60 Hz, 1.70 A maximum input; 65 W is rated DC output. This Dell 16S DS16265 example does not establish other supplies, category bounds or grounding.

Final check: look for "INPUT 100-240V" or a matching local voltage on the label before you plug in.
