That unit looks interesting.

Try going to Duracell’s website. I got spare batteries for my D850 and a usb charger all very reasonably priced. Since it was Duracell I trusted the quality.

Does anyone know how to charge Nikon batteries using a USB connector? When I'm camping in campgrounds with no AC hookups or remote locations I try to bring enough batteries to last me the trip but that is not always practical. I know I can bring a converter that I can convert to AC from my car battery but that means bring another piece of equipment. Is there a way I can use my USB ports in my car or a battery pack to run a battery charger?

PD (power delivery) USB ports are slightly different and few car chargers support PD yet..

I have an Apple charger for my iPhone 15 pro max. I use it to charge my z8s. It works great. I rarely use a battery charger these days Unless I need it charge more than one battery the same time.
