Had that problem a few times at work, needed a choke in series with the power supply to reduce the measurement noise, all they had were good quality toroids. My fix was to put a piece of scrap wire through the toroid and twist the ends together to make a shorted turn...

Q: What's the difference between an authentic Li-ion battery and a counterfeit one?

A: For the former, the battery gets charged. For the latter, the seller gets charged.

If only that's how it worked, most counterfeit sellers just operate from countries that don't enforce it well.
