I just got my Z6iii with 24-120 (Weee!) and after unboxing it, I inserted the battery. Dead! Insert my extra battery I purchased. Dead. No charger supplied, according to regulations from the European Union. We are supposed to use chargers we already have. Looked around for old (and new) chargers in drawers and 220 volt outlets in my apartment. The one I found had USB-A connector and despite that it could deliver 9V and 3A (27W) it didn't charge. After a while I found a charger with USB-C connector that I could borrow for a while.
Went down to the Phone House at the shopping mall and bought a charger and a longer cable USB-C <-> USB-C. Only 550 SEK (US$50). The supplied cable by Nikon is only 60 cm, the new one is 120cm.
So despite EU regulations, some 5 biljon new chargers will be sold due to new standards. Nice with a standard. Everyone has their own. I use my old USB-A-chargers for fast charging of my phone and my tablet, but it cannot charge a Nikon camera.
