Is there a capacity limit for power banks on a Luoyang trip?

[Direct conclusion] Yes, for flights a power bank must not exceed 100Wh (about 27,000mAh) and must be carried on, not checked, and high-speed rail generally requires under 100Wh, so confirm before travel. Key points to keep in mind: 1. Check the power bank rated energy (Wh) label. 2. Ensure under 100Wh and carry on for flights. 3. Note the limit for high-speed rail too. 4. Charge fully and recharge on the go. Note: Carry the original ID and a photo copy saved on your phone before departure.
