Whether you can pack a charger in your baggage in 2026 depends entirely on the type of charger. A standard wall plug with a cable (for a phone or laptop) has no internal battery and is perfectly safe to pack in either your carry-on or checked luggage. However, portable chargers and power banks are a different story. These contain lithium-ion batteries, which are strictly prohibited in checked baggage because they pose a fire risk; if they short-circuit or overheat in the cargo hold, a fire could go undetected. As of early 2026, many airlines like Lufthansa and Southwest have further tightened rules, often banning the use of power banks during flight or requiring them to be kept in seat pockets rather than overhead bins for faster crew response to overheating. A high-value "pro-tip" for 2026 is to ensure any power bank you bring in your carry-on is under 100Wh (roughly 27,000mAh); anything larger usually requires special airline permission, and anything over 160Wh is completely banned from passenger aircraft.
