Not really worried about the Chinese. As was pointed out, they just hang a sword of damocles over the head of every entrepreneur and engineer who even thinks about doing something like that.

What about power banks from India? Vietnam? Malaysia? Korea?

That's what I'm saying. If there are nations where you can get away with it, then those power banks can end up in Western, African or South American markets.

(I'm counting getting a fine, or paying a bribe, as getting away with it. I don't really consider those punishments that will provide sufficient deterrent.)
