Review on 🔋 Sony NP-F550 DOTTMON LCD Battery Charger for NP F970 F750 F770 F930 F950 F960 F550 F530 F330 F570 CCD-SC55 TR516 TR716 TR818 TR910 TR917, NP-FM50 FM500H, QM71 QM91, QM71D QM91D Camera Camcorder Batteries by Mike Travers

Good product. Works perfectly. Charges fast I think due to the power supply (12V) which some might find a disadvantage but I think the charging speed is worth it. USB devices don't charge as quickly, and time on set matters a lot. I use the Black Magic Pocket 6k and 6k Pro so they need constant charging on set so I can keep changing batteries. I actually unpacked this charger on site and it has worked non-stop for 2 days in a row. It has cooling vents and a knob to adjust the amperage to your batteries. Although this is a new brand that I have never heard of, my experience with it has been amazing so I would recommend it.
