I've had this charger for about a month to charge my 21700 battery, and I can't figure out why it does what it does for the life of me. It's honestly the most annoying charger I've ever used.
First off, the only wall adapter I can find that works is from an older Samsung phone. Not the new one that came with my Note 9, but one that's years old from my S5.
Second of all, no matter what the level of the battery I charge is, it sometimes wants to charge at 2000mAH and sometimes I can't even get it to go over 200mAH. I noticed if I put it in the second slot it seemed to hit 2000mAH more often, but now that slot isn't doing it either and I'm currently charging a 3.6v battery at 230mAH.
It just seems like it does whatever it wants to with charge rates, and I can sit there and watch the voltage go up and down a tenth of a voltage back and forth, like it can't even figure out what it's doing. It's honestly the most annoying charger I have ever used. I bought this thing so I could charge at 1000+mAH since my Nitecore topped out at 750mAH, but if I would have known this is how it would act I would have just stuck to the Nitecore and not wasted the money on this.
EDIT: I just took the battery out of channel 2, put it in channel 3 and it read the same voltage of 3.66v and charged at 250mAH. I put it in slot 1 and now magically it's reading 3.77v and charging at 500mAh.
EDIT2: Forgot I made my original post here and saw that XTAR actually replied:

I guess that makes sense. But then my question is, what wall adapter can I use that will provide enough power? I don't want to have to use my laptop every time I charge a battery, but my laptop is currently charging at 967mAH.
