## Questions & Answers

**Q: Attached directly to a power source (2a) it works fine. it doesn't work with 20' extension cable. camera won't power on. why? please tell me**
A: Try a different 20’ extension to be sure it’s not the cord that’s the issue

**Q: Does the sony a7riii comes with the notch for the cable as shown on the picture?**
A: DO NOT BUY THIS FOR THE A7Riii! This isn't the right battery for it. If you have an A7Riii, look for a dummy battery that's marked "NP-FZ100".

**Q: Se puede conectar a una salida directamente de 7.4v, ya que la batería original trabaja en ese voltaje?**
A: Si se puede, de hecho así funciona.

**Q: Does this work with Sony zv e10?**
A: Not sure I have a Sony 6100 4K

### ⭐⭐⭐⭐⭐ Great product, separate barrel plug a bit annoying

Works well, but beware losing the USB to barrel plug connector - it fits standard 12v plugs for astrophotography, and mixing them up seems like it could cause serious problems!

### ⭐⭐⭐⭐⭐ Use USB power not plug...
*by U***A on 19 February 2026*

This review comes within hours of receiving this product so its not a long term use review. What i did want to comment on was if you get this and plug it into a 5v plug like from a iPhone charger etc, you may find lole me that the camera keeps restarting and doesnt stay on. I noticed comments from others for this and similar devices saying there was this problem but they thought it was a faulty product or it broke their camera. My solution to get it working was to simply plug the usb into a hub thats getting power from the laptop. So watch how you are powering this and maybe try a few different sources before writing it off if it doesnt work.
