Sony BC-ZD1 dubbel-batterijlader voor NP-FZ100-batterijen

The dual slots are a lifesaver for back-to-back shoots—I just swap the spent cells into the second bay while the first finishes. Took about two and a half hours as described, but that’s fine since it keeps both ready by morning.

I was worried about the 155-minute charge time, but having both batteries ready at the same time is so much more convenient than swapping them in a single slot. It handles the NP-FZ100s perfectly, though you'll definitely want a good USB PD brick handy.

Finally a dual charger that doesn't feel like a compromise—the USB PD requirement is a bit annoying at first, but once you have the right brick it charges both batteries in about 155 minutes without any heat issues.
