TSA battery rules can be confusing, and summer travel often means long days for both you and your electronics — especially if you’re delayed. If you’re in the market for travel gear, the best way to keep your devices charged is by using a power bank.
But it can be tough to figure out what kind of mobile chargers fit within the Transportation Security Administration or Federal Aviation Administration’s rules so they aren’t taken away at the security checkpoint.
All battery packs face?very strict guidelines?for air travel. Lithium-ion (rechargeable) batteries and portable batteries?that contain lithium-ion can only be packed in carry-on baggage. They’re limited to a rating of 100 watt hours (Wh) per battery. With airline approval, you can bring two larger spare batteries (up to 160 Wh).
Here are our favorite battery packs that are within the FAA and TSA’s rules so you can keep your smartphone, tablet, laptop or headphones juiced up during long airplane rides. Whether you need a boost to keep binge-watching your favorite series or keep up with calls before boarding, these portable chargers will have you covered.
Does TSA allow batteries in carry-on luggage?
The TSA allows various batteries to be carried in your carry-on luggage with some restrictions. Dry cell alkaline batteries like AA, AAA, C, D and 9-volt are permitted, as are rechargeable nickel metal hydride (NiMH) and nickel cadmium (NiCad) batteries.
Lithium-ion batteries, including those in laptops and power banks, are allowed but limited to 100 watt hours per battery, with the option to carry up to two larger 101-160-watt-hour batteries with airline approval.
Lithium metal (non-rechargeable) batteries are permitted up to 2 grams of lithium per battery. All batteries must be protected from damage and short circuits, such as by keeping them in their original packaging or using tape to cover the terminals.
Does TSA allow batteries in checked luggage?
According to the TSA guidelines, uninstalled lithium ion and lithium metal batteries — including power banks — must only be carried in your carry-on luggage.
This is because loose lithium batteries in checked bags pose a greater fire risk if they are damaged, and need to be kept in the cabin where crew can respond quickly in the event of an incident.
Other than this restriction on spare lithium batteries, most common battery types like alkaline, NiMH, and NiCad are allowed in both carry-on and checked bags. Just make sure they are properly protected from damage and short circuits.
If in doubt, consult the TSA’s website. It has a helpful “What Can I Bring?” tool that shows you everything that’s prohibited in checked and carry-on luggage, so you can be sure all your items make it to your final destination.
