Illustrations are at the page this is quoted from, if you’re not sure what exactly to do to check your Nitecore charger.

I own an I4 from several years ago — bought from DinoDirect in 2012
mentioned at 19.79$ shipped - Sysmax Nitecore Intellicharge i4 V2
it fails the magnet test. Hm. Much older model

I emailed Nitecore today since I just found this test page to ask, though it’s performed fine.
I’m guessing it’s an earlier model but not the earliest and that this test is for models made as of late 2014 when they put the method online.

Mine has: — yellow label “Made in China by SYSMAX Ind.” and with SYSMAX Ind and 2051130410076 engraved on the back of the case.
It’s the one that has bays 1 and 3, 2 and 4 paired — the later model differs.
Haven’t taken it apart yet to look at the innards.
