Is a power bank dual voltage?

A power bank's wall charger is dual-voltage (100–240V) — a plug adapter is all you need. Note airline rules: power banks fly in carry-on only, usually under 100Wh (~27,000mAh).

How to read your power bank'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 (charger) · USB-C PD

Label patterns to check before packing

Green-light label "Input: 100–240V~ 50/60Hz (charger)" 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 power bank dual voltage?

Most are. Look for "100–240V" on the label — if it's there, it works worldwide with just a plug adapter.

Can I use a power bank in Europe?

Yes — with a plug adapter for the local socket shape. No converter needed if it reads 100–240V.

Do I need a voltage converter for a power bank?

No — dual-voltage devices never need a converter.

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.
