Is a laptop charger dual voltage?

Almost every laptop charger is dual-voltage (look for "100–240V" on the brick). It works on any grid worldwide — you only need a plug adapter, never a voltage converter.

How to read your laptop charger's voltage label

Find the small print on the device, plug, or power brick.
Read the INPUT line.
"100–240V" means dual voltage (safe worldwide); a single value like "120V" means single voltage.

Common labels: Input: 100–240V~ 50/60Hz · AC 100-240V 1.5A

Dell: 16S 65 W USB-C power adapter specifications: Dell specifies 100-240 VAC, 50-60 Hz and 65 W for this laptop adapter. Other brands and high-performance laptops can use different supplies.

Label patterns to check before packing

Green-light label "Input: 100–240V~ 50/60Hz" means the voltage range is travel-safe; still pack the right plug adapter.

Single-voltage label A single voltage like 120V or 230V means the device is not universal; match it to the destination grid before use.

Missing or worn label Treat it as unsafe until the manufacturer, manual, or power brick confirms INPUT voltage, frequency, and watts.

FAQ

Is a laptop charger dual voltage?

Check the actual input label on your laptop charger or its power supply. A 100-240V range covers those voltages; confirm frequency, grounding and model instructions separately. Category examples do not verify your own unit.

Can I use a laptop charger in Europe?

Only when the actual input rating covers the destination voltage and frequency and the plug fits with required grounding. For a medical device, confirm the exact supply and accessories with its manufacturer.

Do I need a voltage converter for a laptop charger?

No — dual-voltage devices never need a converter.

Adapter vs converter · What "100–240V" means

Guidance only — not professional electrical advice. Always confirm against your device's label before plugging in. Local wiring (especially in hotels and older buildings) can vary.
