Thanks
I had already read the HKJ review.
I bought two VC2 Plus and neither of them gave me problems with the AA / AAA battery charging, it is only slow but for NimH batteries it can be acceptable.
I had problems with two VC4s instead (cable or bad cable contact)
I am satisfied with Xtar, I have a lot of their products, only problems so far only with VC8 and VC4.
My problem with the VC2+ on NiMH was that
a. The batteries (white Eneloops in my case) were detected very slow;
b. Top off charge was capped at 1.45V. Not that the batteries were worn out but on the Maha C9000 these batteries could top off at 1.47-1.52V after Refresh. (Since acquiring my third C9000 I've relegated all NiMH charging routines to the C9000/Pro and nothing else.)
I have since "decommissioned" the VC2+ and given it to someone else for tries, but that was mainly due to the DC input inconvenience.
I don't have the VC4, but AFAIK it accepts only a DC input (same scenario as the VC2+) which requires a special USB-to-DC cable for connection. And besides Xtar there was no other company having made such cable.
Honestly I really think Xtar should just drop the NiMH compatibility on its charger lineup. Having such compatibility means one more thing to worry about when incorporating such charging strategy in the firmware. Like I said before, I'd rather Xtar concentrate and improve the LiIon charging strategy on its chargers, while improving the hardware's QC.
I've tried a few of Xtar's products but the ones I've kept for long are one VC2 and two (or three) VP2s. The first-gen PB2 2x18650 powerbank enclosure was also a joke, and that the internal circuit failed after 1-2 years of frequent use, so I was informed.
