I know this thread is a bit dated but these are 2 I was looking at as well.
I noticed one bit of info that was not mentioned. The c i4 will only charge@ 350ma if charging more than 2 batteries, 750ma for 2 batteries.
the xp4 is not clear but should charge up to 1a to each battery. I am sure the nitecore is great but I think the xp4 might be a better route to take. Can anyone confirm the charge time on the i4 using all 4 slots? 350ma would equate to a slow charger. In theory, better for the battery and run time.
