I was going through A transfer from Tokyo Japan through Beijing China. In Japan (Tokyo) we are told to hand carry our power banks but in China we are told we are told to check it in which causes a lot of confusion and frustration. I have a GOPRO case with an integrated power bank system (under 165kw). When I went through the Chinese customs they confiscated my power bank (to include the case) because they were not sure how many kilowatts it was (funny, it was made in China). I offered to show them a digital receipt which shows my power banks kilowatts on my phone but they said they only accept paper receipts. I mean you would think because it's 2017 innovative places like China would accept digital receipts but no I was sorely mistaken. My suggestion to the Beijing airport is to at least accept digital receipts so nobody experiences getting their personal items confiscated. If the Chinese customs accepted my digital receipt I would still have my 60 euro power bank. On top of that, the staff was very rude. Again, in the Japan (Tokyo) it is REQUIRED for you to carry your power bank and in China (Beijing) it is REQUIRED to check your power bank in; unless you have something IN PAPER stating it's 165kw or under. A great disappointment it is.... I hope to never go back there again.
