Now they are requiring the “CCC” mark, as below. I’ll have to check all my power banks individually, but for certain my Nitecore from ~3 years ago does not have it. I presume power banks sold in China should have the mark? Those not destined for China may be missing it, so international flyers with domestic flights may thus be affected.
At the time, I don't think anyone had that high a capacity yet (or if they did, it wasn't common). The model I had at the time was 4000 or 5000mah... never opened them to look inside, but I would assume maybe three to four cells. These weren't out of China. Brand was "Genius".... was a squarish type with a USB-A to micro as well as two USB-A ports. I remember still seeing them at those warehouse sales here pre-covid, but not since. I think I still have one power bank from that era but I don't use them too much now as I'm not travelling as often and my car has USB ports (and AC plugs) so it's not as much of an issue (unless I need to enable the hotspot on my phone away from any power).
