Can I bring a power bank and charging cables on a plane?

🟢 Yes

Yes, in carry-on luggage. Most power banks under 100Wh are allowed without declaration.

⚖️ Medium Confidence

TSA and most airlines allow lithium batteries up to 100Wh in carry-on.
This covers most power banks (27,000mAh at 3.7V = 99.9Wh).
Larger banks (100-160Wh) require airline approval.
Checked luggage is NOT allowed.

Safe Alternative

This combination works well. No alternative needed.
