Using Your Power Bank Abroad
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
