Chinese Li-Ion Charger - Fake Terminals Going Nowhere !!!
This is a really amazing piece. Just like any other Chinese battery charger, it has a very poor mains isolation, EU plug that doesn't fit EU socket, slight overvoltage, no fuse or EMI filter, .... But on the top of it, it has two pairs of 9V terminals that go nowhere!!! It pretends to be able to charge two rechargeable 9V batteries, but the contacts are really not connected to anything! This is just absolutely awesome. I have never seen this before.
I didn't draw the schematic because the circuit is almost the same as in this 18650 Li-Ion cell charger:
