In this video I’m testing the Llano NP-BX1 2-pack batteries and their 18W fast dual charger for the Sony ZV-1/ZV-1F style cameras. The whole point is simple: I want more runtime without paying OEM prices, but I’m not trusting a third-party battery until I actually put it through real use. So I focus on the stuff that matters when you’re vlogging, traveling, or filming YouTube—charging speed, how long the batteries last, and whether anything gets hot or sketchy during charging. I also answer the big questions people always ask before buying: are these as good as Sony’s original batteries, is “18W fast charging” actually fast in real life, and should you trust third-party batteries at all. My takeaway is based on practical testing and what I’d personally carry in my camera bag when I don’t want a dead camera to end the shoot. If you like straight pros/cons and real-world results, this is exactly the kind of review I do.
