Last weekend at a music festival, I made a super rookie filmmaker mistake: I didn’t check if I had enough juice on my batteries. I’m using Sony NP-FZ100 batteries, and yeah—they hold a lot, but they also charge painfully slow with those old “traditional” chargers you see on Amazon. That setup is honestly my nightmare when I’m on a shoot, doing weddings, corporate events, or anything that runs all day. In this video, I tested the Llano CM3 and talked about why it’s been such a solid replacement for my old charger. The CM3 lets me charge three NP-FZ100 batteries simultaneously (not one-by-one), it’s lightweight and travel friendly, and it supports up to 30W charging over USB-C—so pairing it with a proper 30W brick actually makes charging feel like a problem from the past. I also like the front markers/LCD-style readout that gives an estimated idea of where your battery is at while charging. If you don’t need three slots, I also mention the Llano CM2 two-slot option (around 20W) for a compact, no-fuss setup.
