NEEWER Dummy Battery with AC/DC Coupler Power Adapter Replacement for EP-5B/EN-EL15, Power Supply Compatible with Nikon Z5 Z6 Z7 Z6II Z7II D500 D610 D750 D780 D800 D810 D850 D7000 D7100 D7200 D7500

I recently started using the NEEWER DMW‑BLK22 AC Power Supply Adapter & DC Coupler (ASIN B0D95CVY27) with my Panasonic S5II and I’m very happy with the purchase. It delivers consistent power without relying on camera batteries, so I no longer worry about battery changes in the middle of a shoot. The build feels solid and the cable seems durable, which is exactly what I look for in gear I’ll be using often. What stands out is how easy it is to use: setup was straightforward, the plug fits securely, and the camera recognized the connection without issues. If you’re doing extended shooting sessions — time‑lapses, studio work, or just want to eliminate battery change‑overs — this product works really well. I’d recommend it to anyone who wants reliable constant power for their Panasonic mirrorless camera.

Amazing product, works as expected!

Bought this to keep my camera powered for long periods of time. Functions perfectly for that purpose. I haven't had any overheating issues using this in my camera. Fits nicely into camera and slides back out easily. Perfect for vodcasting or video calls etc.

I am an audio guru but am an illiterate video user. I stumble my way through. I did not know that the battery door on a Canon EOS 7D needs to be closed before it will operate with any dummy battery. Thank God for Google. I removed the rubber grommet and ran the cable out of the battery comparment so I could close the door. Bingo, worked great.

I have 2 Nikon Z30s that I use mainly for recording YouTube videos and teaching over Zoom. The Z30, as well as other Nikon, Sony, Canon, and similar cameras, are all known to overheat when using the standard battery while recording video. When they overheat they stop. This can often happen after only 30 minutes! That's really not acceptable from what is supposed to be "pro" gear. There's a notch in the battery compartment door where the dummy battery cord can go through, so it seems Nikon knows about this problem and knows people will use a dummy battery. I don't know why these companies don't address this issue. The dummy battery does 2 things. First, it doesn't get hot like an actual battery, which helps keep the whole camera cooler and working. Second, it allows you to power the camera through a standard AC plug and avoid having your battery run down in the middle of recording. You can get cooling fans that attach to the back of the camera, but they can be noisy and also run out of power. This is a much better setup, especially in a studio situation.

This device fits into the battery slot of my Nikon Z6, and powers it on. However, after 30 minutes to one hour, the camera turns off. The battery level usually shows as 3/4, and doesn’t lower, even before it turns off. When it turns off, I can make it work again by turning the camera off, unplugging the power supply from the wall outlet, taking the battery out of the camera (I just unplug the barrel jack connecting the dummy battery to the power supply), waiting a minute, and repeating those steps in reverse. This usually fixes it, but the camera turns off, which isn’t great for timelapses or videos. I can also put a real battery in the camera while waiting for the dummy battery to work again. A genuine Nikon dummy would probably work, although I haven’t tried one because it’s quite expensive.

working good so far to convert my camera into a webcam type setup. can't really speak to long term durability or reliability as i've only had it for about a month. but for that month... so far so good. will update my review if anything breaks.

Upon first glance and inspection, the dummy seems like everything should fit just fine but when I inserted the battery I immediately felt it was a little mushy with some room inside the compartment. No problem I thought should work just fine. WRONG. It would start up but any wiggle or movement or sometimes seemingly for no reason at all it would shut off as the contacts were not properly seating into the camera. I took it out the dummy and compared it directly with my OEM battery and sure enough, it was just a hair shorter and the contact points are recessed deeper than the OEM battery but significant enough to cause issues to functionality.

Working well and great to have to longer at home video productions. Particularly for actor’s self-tapes.

Bought this so my Lumix s9 could run longer in a corporate setting on a live feed. This solved all our issues

Works great on my LUMIX S9! I use it to stream on Twitch and it hasn’t failed on me yet

This Neewer NP-FZ100 AC Power Supply Adapter with Dummy Battery has been a total game-changer for my Sony ZV-E10 II setup. I use it for studio shoots and long recording sessions, and it provides constant, reliable power without worrying about battery swaps or unexpected shutdowns. The dummy battery fits perfectly, and once plugged in, the camera runs as if it’s on a fully charged battery — no errors, no overheating, and no issues at all. The adapter stays cool during use, and the cable length is generous enough to route neatly around my desk or rig. It’s especially useful for talking head videos, overhead product shots, or anything where I need the camera powered on for extended periods. Paired with a UPS or surge protector, this gives me peace of mind during important recordings. If you're running a Sony camera in a studio or stationary setup, this is a must-have accessory. Affordable, dependable, and works exactly as expected with my ZV-E10 II.

Funciona muy bien, la he usado por más de 3 horas y sin ningún problema
