Plus, all the nitecore chargers drop down to a 350mA charge as soon as you plop in more than one battery, which is painfully and obnoxiously slow for any battery above 2000mAh. The Xtar 4 bays can do 1000mA x2 and 500mA x4 charge, the difference being hours and hours quicker.
Actually the D4 is 750mA 1 or 2 batteries, 500mA 3-4 batteries.
I'd recommend the Xtar XP4. Xtar has better QC and warranties. I've always read about the occasional dead Nitecore charger, never an Xtar.

With how slow the Nitecore works, you'll get more batteries charged using one slot on an Xtar charger compared to using all four in an i4 intellicharger. Make sense?
Good luck
Xtar has a sale going on ATM.
VP1 and VP2.
They have also just released the VP4.
Worth checking out.
Yeah, another Xtar, but they really are very good.
Nitcore intelligicharger
Best vaping purchase Ive made with the exception of my Provari.
You got lucky. (Not kidding.) These people? Not so much...
