TSA item rule · verified 2026-07-02
Can you bring power banks & portable chargers on a plane?
TSA's official answer, checked against tsa.gov on 2026-07-02.
Carry-on bag yes
Carry-on only. Up to 100 Wh (that's most consumer power banks — roughly up to ~27,000 mAh at 3.7 V). 101–160 Wh needs airline approval, max two.
Checked bag no
Power banks are spare lithium batteries — prohibited in checked bags.
Liquids, gels and aerosols in carry-on follow the TSA 3-1-1 rule. The final decision always rests with the TSA officer at the checkpoint.
