I want to go shanghai at november.. can i bring my powerbank for Handphone?

As I know, the capacity under 100wh can be brought on the plane, while the capacity between 100wh and 160wh need to be well-wrapped and meet the agreement of the airline company. In addition, your powerbank must be marked with the manufacturer, capacity, input and output voltage.

Thx to your answer...

I arrived at pudong airport at mid night, can i buy sim card china unicorn at there? And how much?

As I know, you can find the service office of China Union on F1 in T1. However, it may close at the midnight. As a result, you are advised to buy one at the service office near your hotel on the next day.

My flight is in the T2 PVG.
