NEEWER Dummy Battery with AC/DC Coupler Power Adapter (Replacement for EN-EL15 / EP-5B) for Nikon cameras
Product description
What it is and why people buy it
A dummy battery with an AC/DC coupler is essentially a way to keep a Nikon camera powered for long sessions without relying on a normal battery pack. On paper, the idea is simple: you replace the camera’s battery with this dummy battery, then feed it power via the included AC power adapter. For filming, time-lapse style shoots, studio work, or any setup where you’d rather not keep swapping batteries, it can save hassle.
This NEEWER kit is positioned as a replacement power supply aimed at specific Nikon models listed in the compatibility line: Nikon Z5, Z6, Z7, Z6II, Z7II, D500, D610, D750, D780, D800, D810, D850, D7000, D7100, D7200, D7500. It’s also described as a replacement for EP-5B using the dummy coupler battery with an AC power cord and adapter.
The essentials: how it works in real terms
The setup process is described as straightforward and it’s worth highlighting what that means in practice. You remove the original battery, insert the dummy battery into the camera’s battery compartment, close the compartment cover, then connect the dummy battery to the AC adapter using the coupler connection and finally plug the AC adapter into the mains.
That “few steps” flow matters because these kits live or die by whether they’re quick to deploy. If you’re setting up for a long shoot, you don’t want to be wrestling with cables or repeatedly opening and closing the battery door.
One important limitation is explicitly stated: the dummy battery cannot power the camera on its own. It’s designed to work only with the compatible power adapter. So if you’re expecting it to act like a normal battery with charge stored inside, you’ll be disappointed—this is a tether-to-mains approach.
Where it shines (and what you’ll notice day to day)
If your workflow involves “camera on for hours”, this kit is built for that scenario. The biggest day-to-day win is continuity: less battery management, fewer interruptions, and a more predictable run time when shooting for extended periods.
It also makes sense for scenarios where power stability matters more than portability—think controlled environments like workshops, classrooms, studios, or any time you’ve already got mains nearby.
Also, there’s a practical note for proper functioning: after inserting the dummy battery, you need to ensure the battery compartment door is properly closed. In other words, it’s not just a slot-in accessory, the camera needs the compartment closed for reliable operation.
What to check before you buy
Before committing, make sure the camera model you have is truly covered by the compatibility list. This product is written for Nikon models including the Z5/Z6/Z7 series and various D-series bodies shown in the description. If your camera isn’t on that list, it’s safer not to assume.
You should also check your expectations around power type. Because it’s an AC/DC coupler solution, you’ll need access to mains power during use. If you’re shooting outdoors, travelling, or you often rely on battery-only operation, this may feel restrictive compared with a standard rechargeable battery or a battery pack system.
Finally, consider your physical setup: dummy battery solutions require the battery door to be closed correctly. If your rig includes tight cages or unusual battery compartment clearance, the “close the door” step becomes more than a formality.
Technical details (as far as the listing states)

No further internal specs are provided in the listing, so it’s best to judge it primarily by compatibility and your power needs.
Mini FAQ: common questions
Is this a charger for a regular battery?
No. The description frames it as a dummy battery replacement with an AC power adapter so the camera can be powered from mains for long hours. The dummy battery is not meant to power the camera separately.
Will it work if I don’t connect the AC adapter?
The listing notes that the dummy battery must work with the power adapter and cannot power the camera separately. So you’ll need the included adapter and mains connection.
What’s the key setup step people might miss?
Closing the battery compartment door after inserting the dummy battery. The listing specifically calls this out for proper functioning.
Does it suit both Z-series and D-series cameras?
According to the compatibility line, it’s intended for both Nikon Z5/Z6/Z7 (and Z6II/Z7II) and a range of D-series models including D500 and several others listed.
Final verdict
It’s a solid pick if you frequently shoot sessions where your camera needs to stay powered for hours and you have mains access. The dummy battery + AC adapter approach is the practical answer to “running out of battery” mid-shoot, and the setup steps described are manageable.
It’s not the best choice if you need a portable, battery-only power solution. Because it can’t power the camera by itself, you’re essentially planning around the plug.
Worth considering if your priority is convenience and continuity over mobility, and you’re confident your Nikon model is within the list provided. If you’re unsure about compatibility or you often shoot away from mains, you may want to stick with a standard rechargeable battery approach instead.
