Can power banks go on high-speed rail and planes; what capacity limit in Luoyang?

[Direct conclusion] 【Power banks are allowed on trains and planes but must be carried on, never checked, with rated energy ≤100Wh (about 20000–27000mAh) generally fine; 100–160Wh needs airline approval; unmarked or damaged ones are banned.】 Limits: A commonly missed point—checked ones get confiscated. Key points to keep in mind: 1. | Capacity | Train | Plane | |---|---|---| | ≤100Wh | carry | carry (≤2) | | 100–160Wh | carry | airline ok | | unmarked/broken | no | no | ◆ Tip: pick a marked bank; never check it on planes; our vans have USB ports. 2.
