Sony just released a new Sony BC-ZD1 Dual-Battery Charger and Sony DC-C1 DC Coupler that allows you to charge NP-FZ100 batteries from PD power banks.
Sony BC-ZD1 Overview
The BC-ZD1 Dual-Battery Charger for NP-FZ100 Batteries from Sony is an ideal and efficient way to charge two high-capacity NP-FZ100 batteries simultaneously, assuring you have ample power for use at events or in applications that require continuous operation over extended periods of time. The BC-ZD1 can fully charge two battery packs in 155 minutes using a separately available USB-C charger.
Sony DC-C1 Overview
The DC-C1 DC Coupler from Sony provides continuous power to compatible cameras via USB PD, allowing for extended hours of operation. The coupler has a built-in 5.2′ cable and NP-FW50 type coupler. It also includes a plug-in adapter plate to fit the battery slot of cameras that use NP-FZ100 batteries.
To prevent accidental disconnection, a separately available USB-C connector with a locking screw can be used, or the cable can be supported through the anchor loop.
