I gotta say.. after spending thousands of dollars on a camera, it’s products like these that swoop in and provide relief. I usually prefer OEM everything on any device that surpasses 1k, however my intent was to eventually have two of these in total anyways, so I decided to at least give this brand a try first, from experience.. I have already purchased numerous NEWEER products for many other items I own because they truly are an amazing brand. You can tell the company has quality standards and thus far they have never disappointed me.For a fraction of the cost this product works flawlessly with the NIKON Z7ii, I have absolutely zero complaints.It gives you the same feel and look as the full body size Z9 or similar camera.I’ve toggled back and forth with and without this extra battery pack because clearly size can get in the way sometimes so it’s nice to have the option to shed weight and profile when and if need be, as well if I’m only shooting stills then it’s really not necessary, but there when you need extended video clips or long shoots, either way just a great add on to have.As pictured I have it attached to a frame rig designed for the Z7ii with Mb-N11battery grip, the fit is perfect.To each their own, as everyone has their own specific needs, wants, or requirements. This offers you a way to save hundreds of dollars and provide the same capabilities.Yes, it can be charged via USB C while attached to camera at the provided port.The batteries provided with it are recognized fully by the Z7ii, all the buttons sync up and operate absolutely fine. NEWEER products are always on my radar, as they provide great alternatives to so many different brands!
