Disposable vapes were banned in the UK. Which in practise has meant that manufacturers have added the cheapest possible charging port which is non-standard so nobody can charge them and no way to open them to refill them.

I actually read the article you linked and these are clearly just shopkeepers breaking the law, lying about these being compliant. There is no legal loophole, except if you count a lack of enforcement as a loophole.
