I bought this Bionx charger online that has the wrong output for my Bionx. I based my decision on the model #: HP8204C(10S). It turns out that the output is different. The one I bought has 36VDC/2A. Mine uses 42VDC/2A. Why Bionx has the same model # with different outputs is a question for another day.
Anyway, I’d be willing to trade this 36VDC one for a 42VDC one? Also, it should have 4 prongs. The seller called this charger new and it certainly looks new. If anyone is interested email me at topbrand gmail com. I’ll send you this one for your 42VDC one. Thanks in advance.
