Carry-on power bank visibility card

Ready-to-use prompt

Create a carry-on power bank visibility card for business trips, family travel, camera trips, or student luggage. Include Wh/mAh conversion reminder, 0-100Wh, 101-160Wh, and over-160Wh zones, carry-on only, terminal short-circuit protection, keep it visible when in use, check airline-specific rules, remove it before gate-checking a bag, and ask crew for help if it gets hot or swells. Make it look like a clear pouch card plus phone note. Do not use airline or battery-brand logos, and do not encourage bypassing security or using power banks on flights where use is banned.
