Using my Sony A7r iii as a webcam for a premium work conferencing video experience. This camera won’t charge the battery while in use so this product takes the place of the battery and makes the camera think it has an infinite power supply. On my camera the battery door detaches to support a battery grip which for this use case allows the power supply wire to exit the body and hang freely. Great product. Highly recommend.

Product came on time and works well

I’ve had this dummy battery for a little over a year now, and I don’t think I’ve had a single issue with it! The overall quality and battery life are exactly as described, and it’s a great product for its price.

Pretty inexpensive for the flexibility of being able to put a camera in a hard to reach spot for a long live production. Compatible with Sony cameras without any issue, the power supply runs for as long as you need it (5 hours for me without any heat issues) it is sort of fragile so be sure not to kink the cord.

This product allowed me to do back to back to back interviews with my camera rig (Sony a7sIII) without having to worry about running out of battery. Proved to be very helpful!

Unit worked fine for months, until the Sony battery warning triggered every power up indicating the battery was not safe. I reached out to seller to inquire about this and the longer than expected warranty, and they advised me that they updated some battery software to keep pace with Sony and they would send me a replacement unit free of charge. Within two days I had a brand new, working battery. The customer service from this team was spectacular, and I totally expected the usual “send us your battery and we will take 6 months to look at it” but boy, was I wrong.

This is the best thing you can buy if you use a static/tripod camera. Anxiety is gone, battery is always 100% charged.

So I got this to be able to use my A7iii as a stream camera and the one thing I was worried about was the infamous not a genuine sony battery message. Not a deal breaker but would be annoying to deal with waiting for it to appear after a few minutes. Happy to report that this does NOT trigger that warning on the latest 4.01 firmware of the Sony A7iii. I just pop it in, run the cable out the port of the battery hole, and off to the races I go! Very very satisfied!
