Whether chargers can go in checked luggage depends entirely on whether they contain an internal battery. Standard wall chargers (the plastic bricks with no battery) and simple cables have no restrictions and can be placed in either checked or carry-on bags. However, portable chargers and power banks (which contain lithium-ion batteries) are strictly prohibited from checked luggage by the FAA and TSA in 2026. This is because lithium batteries pose a fire risk; if they short-circuit or overheat in the cargo hold, a fire could go undetected. If a battery is installed inside a device—like a laptop, phone, or camera—the device can be checked as long as it is completely powered off, though airlines still strongly recommend keeping these in your carry-on. In 2026, many airlines have become even stricter, with some requiring portable chargers to be kept "on your person" or in a clear pouch for visibility, ensuring that the crew can quickly respond to any "thermal incidents" or smoke during the flight.
