Nikon Japan has announced that due to parts shortages, the EH-7P USB Charger will no longer be supplied with the Z7 and Z7 II. However, it’s not clear if that’s a regional or global decision (as of serial numbers in the 8000’s, it was still in US Z7 II boxes). While the EH-7P has been available separately, it tends to be in and out of stock (currently out of stock at this site’s exclusive advertiser, B&H).
The good news is that the EH-7P is basically a USB Power Delivery wall wart. Any certified USB Power Delivery wall wart should work to charge or power the Z6 II and Z7 II models via USB-C. The EH-7P is 5 volt, 1 amp, so any USB Power Delivery above that should work fine.
