Safety: Power banks contain lithium-ion cells. Use the cables the manufacturer supplies or recommends, keep the unit away from heat, never use a damaged or swollen battery, and follow the manual. Airline and aviation rules change, so check the sources below before you travel.
Yes, you can usually bring a power bank on a plane, but it must go in your carry-on, not your checked bag. The limit that matters is the watt-hour rating printed on the unit, not the mAh figure on the box. This guide shows how to check your bank before you fly.
If you carry a larger laptop bank, see our guide to flying with a laptop power bank.
Step 1: Keep It in the Cabin
The FAA’s PackSafe guidance says spare lithium batteries, including power banks, must travel in the cabin with you. A damaged battery can overheat, and crews can respond to a problem in the cabin faster than in the hold.
Step 2: Find the Watt-Hour Rating
Look for “Wh” on the label. If only mAh is printed, convert it using the steps in how to convert mAh to Wh. Airlines and regulators set limits by watt-hours, and banks above the standard limit may need airline approval or may not be allowed.
Step 3: Check Your Airline’s Policy
Airlines can set stricter rules than the FAA, including limits on use during the flight. Read your airline’s current policy before you travel, especially on international routes.
Step 4: Pack It Safely
Carry the bank in a pocket or bag, not loose with keys or coins. Do not pack a damaged, swollen or recalled bank. Protect the ports from contact with metal.
| Do | Do not |
|---|---|
| Carry it in the cabin | Put it in checked baggage |
| Check the Wh label | Rely only on mAh |
| Follow your airline’s rules | Charge it under a seat cushion or blanket |
Frequently Asked Questions
Can I put a power bank in checked luggage?
No. The FAA says spare lithium batteries, including power banks, must be in the cabin.
Is a 20000mAh power bank allowed on a plane?
Often yes, depending on its watt-hour rating and your airline. Check the label rather than relying on mAh.
Can I use my power bank during the flight?
Some airlines restrict use. Check your airline’s policy, and stop using a bank that becomes hot.
