Here's why:
* Lithium-ion batteries: Most car battery chargers use lithium-ion batteries, which are considered hazardous materials by the TSA and most airlines.
* Safety concerns: Lithium-ion batteries can overheat and potentially catch fire, especially if they are damaged or improperly packaged.
What you can do:
* Check it as luggage: You can usually check your car battery charger in your checked luggage, but it's always a good idea to contact your airline beforehand to confirm their specific regulations.
* Buy one at your destination: Consider purchasing a car battery charger at your destination if you need one.
* Use a portable jump starter: A portable jump starter is a safe alternative to a car battery charger. These devices typically have a smaller battery and are approved for carry-on luggage.
Important note: Always check the latest regulations with your specific airline before traveling with any electronic devices or batteries.
