There are some differences between the i2 and the i4.
charge rate 2 cells only
charge rate 4 cells
additional cell type
i2
500ma
i4
750ma
375ma
Li-ion 10440
So the i4 will charge faster for 2 cells only.
I think what you are saying is that if you buy 2 pieces of the i2, it will cost you $29.40, so you might as well buy the i4 at about $9 less. This makes sense if you are OK with the charge time for 4 cells. I charge my AA Nimh cells at 1000ma with a Maha C9000.
And don’t forget the BLF discount on either one.
I have a 12v/24v cigarette lighter adapter cord for a revive-refresh battery charger, the tip also fits the Nightcore i4, is it OK to use that adapter?
not if the polarity and voltage is right .. The nitecore is a simple 12volt ..it doesn't say on the body whether it's center pos. or neg ... maybe in the paperwork ....
Usually this type of connector is center positive, otherwise it is too easy to come in contact with a conductive item.
Test it with your DMM. Plug the unit into a live 12v circuit. Put the positive lead on the center of the plug, and the negative lead on the outside of the plug. A positive reading (12v) will confirm center positive. A negative reading (–12v) suggests a negative center (unlikely). Be careful!
Edit: I think I got the question wrong. You’re asking if the i4 is center positive. That I can’t say for sure.
Hi guys, I just test mine, center positive and outside negative, this is almost a standar in this kind of connectors… The size of the connector is 5.5mm and inside is like 2mm
Could somebody help me how to recognize fake i2 charger.
Five of those arrive in fact three different style & size of packing.
Two of those includes new Qr code so I hope those are orginal Nitecore products.
Have I to open all of those and take pictures of circuit board or what?
