The rules for chargers in suitcases in 2026 depend entirely on the type of charger. Standard wall chargers and cables (which do not contain batteries) are perfectly safe and allowed in both checked and carry-on luggage. However, portable chargers and power banks—which contain lithium-ion batteries—are strictly prohibited in checked suitcases. This is due to the fire risk; if a lithium battery short-circuits or malfunctions in the cargo hold, a fire could go undetected by the crew. Consequently, all power banks, spare batteries, and "smart luggage" with non-removable batteries must be carried in your hand luggage. In early 2026, many global aviation regulators (including India's DGCA) implemented even stricter rules, banning the use of power banks for charging devices during the flight to prevent overheating in the cabin. Most airlines limit power banks to a capacity of 100Wh (roughly 27,000mAh), with larger ones requiring prior approval. Always check that your portable charger's capacity is clearly labeled on the device, as customs officials may confiscate unlabeled batteries to ensure they meet safety standards.
