Coiled DC Power Cable Adapter + DC Coupler Dummy Battery NP-FZ100 for Sony ZV-E10II ZV-E1 FX2 FX3 FX30 A1 II A7C A7V A7III A7RIII A7SIII A7RM4 A7RIV A7RV A9 II A6600 A6700 A7CR A7CII Camera

I have a brand new A7iii that I used about only five times. No scratches no drops nothing of that nature. Took it to Best Buy had Geek Squad ship it out they told me that the only thing they can think of is the dummy messed my camera up because it's not Sony brand. The camera was $2,500, the repair was $600. Now I'm in the process of getting my camera fixed since the people who were supposed to repair it damaged it even more. I would not suggest this battery!

Unfortunately didn't work at all. Tried multiple cameras and power sources. Looks like a lot of people have this issue.

The battery piece itself feel a bit light, but it locks right into place securely. The weight put me off at first but I realized that it put little/no stress on the plastic battery lock and adds very little weight the the rig. The DC connector fits snuggly.Overall works like a charm and doesn't add much weight!
