Sony Mehrfachbatterieadapterset NPA-MQZ1K

Finally, a charger that can handle all four NP-FZ100 batteries at once without overheating. The build is solid, and the charge time for two batteries is noticeably faster than my old single-slot charger.

The adapter feels solid and snaps into place cleanly. It's great being able to swap between two included NP-FZ100 packs for extended shooting without scrambling for a charger.

The fact that this adapter holds four NP-FZ100s at once is a game changer on long shoots—I've gone a full day of video work without touching a charger. The two included batteries are a nice bonus, and swapping them in feels solid, no loose grip or fiddly contacts.
