I bought this to use with my Sony RX100 VII. I use the camera with a cam link for live streaming video games. Turns out the the door is attached to the mounting hole for tripods, so you can not have the door open and use a tripod, making this unusable for someone like me.

pair this with external power bank is the way to go. don't have to worry about damaging the battery. It doesn't feel much heat as feeding power bank through the battery.

Every content creator needs one of these to save you time from charging battery’s and on the go works in a pinch being USB can plus it into a car lighter socket with car charger plug. It’s truly the Endless Battery.

I have it plugged in a portable (30k) 30,000 mA Battery and just change those out for live-streaming on the go.

Great way to banish your battery anxiety, plug it in to the wall to shoot all day, use a battery pack for on the go.

If you have a Sony RX100 IV(and likely other versions) there is a small moveable tab on the battery door that allows you to pass out the power cable and keep the door latched.

I bought this to use with a stabilizer for my Sony RX100V. This dummy battery works perfectly with the camera and allows me to power it with a external usb battery pack.

Useful to use Camera for long periods with large SD Cards that last longer than internal battery.

Great little unit. I use this to let my cameras run all night to do work monitoring and recording wildlife. Fits a little snug making it difficult to remove but that also keep it in place nicely. Works great.

I use this dummy - battery for my Sony RX100 IV

I use this with my Somy RX100 V along with a remote trigger for slow motion shots, works very well.

I bring this on trips along with a 20,000maH battery bank and has worked reliably every time.

The only annoyance is the cable, I wish Sony had opted to put the hatch cover on the side of the camera rather than directly below it.

works well with RX100 m4 and m5
