I got in last week the China made (Black) P4 Multi Battery charger in. Looks like the same as the P3 but black and not blue. Same build quality and same fan sound when connected more then 1 battery. I did notice the power cord is a little thicker but pretty much the same. You can charge up to 3 batteries and 1 remote at the same time. I think I paid 60 bucks from eBay and it took 14 days to arrive here in Texas.... Well worth the money and I wouldn't even think about buying the DJI white plastic charger they just came out with for 90 bucks and charges only one at a time.
