Looking at TikToker @meaijeaw’s video of heaps of portable chargers strewn in boxes, you could easily mistake it for a shop having a big sale on power banks. Dubbing it "power bank cemetary", the TikToker's post is actually a scene from an airport in Xinjiang, China, where the numerous power banks are actually those that have been confiscate by security and immigration officers. Since June 28, China has imposed a ban on non-approved power banks on domestic flights.
