The Nitecore UFZ100 camera battery is here to release photographers from Sony’s proprietary grasp — a built-in USB-C charging port lets you power it up using the same hardware as many of your other devices. It hasn't been officially released yet, but you can use the battery with the Sony A7 III, A7R III, A7R IV, A7S III, A9 (ILCE-9), A9 II, A6600, A7C, A1, FX3, and A7 IV, saving you from lugging around a separate charger if you want to bring along (and charge) an extra battery on a shoot.
Reliability and price have not been made known yet though. So yes there may be some trade-offs as certainly the capacity is slightly less, with a longer charging time.
