Nikon EN-EL15 DC Coupler with USB-C Input for by Wasabi Power

Works, but needs enough power

I bought this with hopes of it connecting to the Ronin 3 and powering the Z8 but I have had 0 luck. When I power via battery pack, it works. The corded cable is nice though to eliminate some pull, but it doesn't solve one problem without creating another.

Works perfectly

I was a bit concerned about how the cord was going to exit the battery holder space! The directions that came with the unit, pointed out that my camera might have a removable plug of sorts that would allow the cable to exit while closing the battery door. I had no idea my camera might have that option. It did and the unit works great!

Excellent customer service!

I ordered the battery adapter to use on my Nikon D600 to do extended timelapses. The drawback is that it requires a battery source that takes a USB-C output. I got a USB-C to USB-A adapter but that didn't work. I contacted the seller and they immediately sent me a replacement. As it turned out, I also purchased a battery pack with a USB-C output and found out it did work. I tried to return the replacement but the seller told me not to worry about it. Great people to buy from!
