🔌 Travel adapter / plug

Nothing at all — travel adapters are permitted everywhere and attract no security concern. They carry no battery and are treated like any other electronic accessory. Pack it wherever is most convenient.

No — travel adapters face no restrictions in carry-on or checked baggage in any region. Unlike power banks or chargers with built-in batteries, a passive plug adapter has no components that raise safety or security issues. You can pack it in your checked bag, your carry-on, or your personal item without any concern.

Multi-plug adapters and travel surge protectors occasionally produce a slightly complex X-ray image, and a screener may pull the bag for a quick look. Once they identify it as a passive adapter with no battery, it goes through without issue. If your surge protector also functions as a power bank with a built-in battery, that battery element is what determines the rules — not the adapter itself.

Either works fine, but carry-on is often the more practical choice since you may want the adapter at your destination before your checked bag arrives at the carousel. There is no security or regulatory reason to prefer one over the other — the decision is purely about convenience.
