Phone chargers are allowed in checked luggage, but the rules depend on the type of charger and the airline

Most standard phone chargers—the kind that plug into a wall outlet—can go in your checked bag without restriction. USB chargers, car chargers, and wireless charging pads are also fine. The real concern is lithium batteries, which power some chargers and are heavily regulated because they can overheat in cargo holds. If your charger contains a built-in battery (like a portable power bank), you'll face stricter rules.

The safest approach is to pack at least one charger in your carry-on bag instead. That way, you have it when ready when you land, and you avoid any confusion at check-in. If you're traveling with multiple chargers, splitting them between checked and carry-on luggage is a practical solution.

Key Takeaways

  • Standard wall chargers and USB chargers with no built-in battery are allowed in checked luggage on all major airlines.
  • Portable power banks with lithium batteries are restricted to carry-on bags only and must meet specific watt-hour limits set by the TSA and your airline.
  • Packing at least one charger in your carry-on ensures you can charge your phone when ready after landing.
  • Check your airline's website before packing if you have a power bank or solar charger, because limits vary by carrier.

Standard chargers that are safe in checked bags

Wall chargers, car chargers, and USB-C chargers without built-in batteries pose no safety risk in checked luggage. These are passive devices—they don't store power themselves, they just convert electricity from an outlet or car port to charge your phone. The TSA and all major airlines (United, American, Delta, Southwest, and others) allow them in checked bags without limit.

Wireless charging pads also fall into this category. As long as there's no battery inside the pad itself, it can go in your checked bag. The same applies to multi-port USB hubs and charging cables of any length.

Portable power banks: carry-on only

Portable power banks—the small rectangular devices you use to charge your phone on the go—must stay in your carry-on bag. They contain lithium-ion batteries, which the TSA classifies as dangerous goods in cargo holds because they can catch fire if damaged or short-circuited.

The TSA limits power banks to 100 watt-hours (Wh) per battery in carry-on luggage. Most consumer power banks fall well under this limit—a typical 20,000 mAh power bank is around 74 Wh. Check the label on your power bank for the watt-hour rating. If it's above 100 Wh, you cannot bring it on a plane at all, whether in carry-on or checked luggage.

You can bring up to two power banks in your carry-on bag, as long as each one is under 100 Wh. Some airlines allow a third if it's between 100 and 160 Wh, but this varies—check with your specific airline before packing.

Solar chargers and other battery-powered devices

Solar chargers with built-in batteries follow the same rules as power banks: carry-on only, and the battery must be under 100 Wh. Hand-crank chargers (which generate power by turning a handle) have no battery, so they're fine in checked luggage.

If you own a car charger that plugs into a 12-volt outlet and has no battery, it's safe in checked luggage. But if it has a built-in battery for emergency power, treat it like a power bank and pack it in your carry-on.

What happens if you pack a power bank in checked luggage

If a power bank ends up in your checked bag, the airline may discover it during screening and confiscate it. You won't be charged a fine, but you'll lose the device. In rare cases, if the battery is damaged or poses an when ready fire risk, the airline may refuse to load your bag onto the plane at all, which delays your flight.

The rule exists because cargo holds are unpressurized and unmonitored. If a lithium battery overheats, no one can respond quickly. Packing power banks in carry-on bags keeps them where crew members can see and address any problem when ready.

How to check your charger before packing

Look at the label on your charger or power bank. It should list the battery capacity in milliamp-hours (mAh) or watt-hours (Wh). If it only shows mAh, you can estimate watt-hours by dividing mAh by 1000 and multiplying by the voltage (usually 3.7V for lithium batteries). A 20,000 mAh power bank at 3.7V is roughly 74 Wh.

If you can't find the label or the math seems unclear, contact the manufacturer or check the product manual online. It takes five minutes and prevents problems at the airport. Your airline's website also lists specific rules—search for "lithium battery" or "power bank" on their baggage page.

Packing chargers for international flights

International airlines follow similar rules to U.S. carriers, but some are stricter. European airlines, for example, may have lower watt-hour limits or different rules for multiple power banks. If you're flying outside the United States, check your specific airline's baggage policy before packing.

The safest strategy for any flight is to pack one standard wall charger in your checked bag and one in your carry-on, plus any power banks in your carry-on only. This covers you no matter what the rules are, and you'll always have a way to charge your phone.

Frequently Asked Questions

Can I pack multiple chargers in my checked bag?

Yes, as long as they're standard chargers without built-in batteries. You can pack as many wall chargers, USB chargers, and cables as you want in checked luggage. Power banks must go in carry-on only, limited to two per bag (or three on some airlines if one is between 100–160 Wh).

What if my charger has a small battery for backup power?

If it has any lithium battery, it must go in your carry-on bag and meet the 100 Wh limit. Check the label or manual to confirm the watt-hour rating. When in doubt, pack it in carry-on to avoid confiscation.

Are fast chargers allowed in checked luggage?

Yes. Fast chargers (20W, 30W, 65W, etc.) are standard wall chargers without batteries, so they're fine in checked bags. The wattage rating refers to charging speed, not battery capacity, so it doesn't trigger TSA restrictions.

Can I bring a car charger in my checked bag?

A car charger that plugs into a 12-volt outlet and has no battery is allowed in checked luggage. If it has a built-in battery for emergency power, pack it in carry-on instead and confirm it's under 100 Wh.

What should I do if my power bank is over 100 Wh?

You cannot bring it on a plane in either carry-on or checked luggage. Leave it at home, ship it separately, or buy a smaller power bank that meets the limit. Some travelers mail high-capacity power banks to their destination instead.
