Whichever one you get.
Some charge at 3A per. some at .5A’ish per cell.

The slow charge does better job and gives more longevity per battery.

Lot’s out there. I Use XTAR VC4 at home.
Xtar VC2 for car.

I’m not planning on getting any other charger. I was asking because already have and using the Nitecore D2 Digicharge but doesn’t seem to be charging because is taking long time, unless it’s just slow charging like you said.
