NP-FW50 Dummy Battery AC-PW20 AC Adapter Kit for Sony cameras (continuous power for filming & live streaming)

The essentials

If you shoot for long stretches—videos, livestreams, studio sessions, or video calls—battery swaps can quickly become a nuisance. This NP-FW50 dummy battery and AC-PW20 AC adapter kit is designed to keep your compatible Sony Alpha/NEX-style camera running from mains power, so you can focus on the shot rather than the battery indicator.

On paper, the idea is straightforward: the dummy battery replaces the NP-FW50 battery, and the AC adapter continuously powers the camera. That said, it’s not a universal solution. There are some important compatibility boundaries (and a couple of “small things” that matter in daily use), so it’s worth checking your camera model before you buy.

What it’s for (and what you’ll notice)

This kit is aimed at situations where you benefit from steady, continuous power.

A practical example: imagine recording a vlog-style talking head in a single location for 45–60 minutes. With continuous mains power, you’re not juggling battery changes or worrying about the session ending abruptly mid-take.

It also fits workflows like: - long video shoots where you don’t want interruptions - live streaming and broadcast-style setups - video conferencing and other “keep it running” moments

Where it can feel a bit limiting is when you simply don’t need mains power—if your usual shooting is short bursts outdoors, a dummy battery kit may end up being overkill.

Compatibility and requirements

This kit is described as fitting a range of Sony cameras including models such as ZV-E10, A6000, A6300, A6400, A6500, A5000, several A7-series bodies (as listed), and NEX series models (as listed).

Worth noting: it is explicitly stated as NOT for certain Sony cameras, including the DSC-RX1 / RX100 / ZV1 / A6600 and also not for A7 III and A7 RIII (plus a few other listed names). If your camera is one of the excluded models, this won’t be the right approach.

There’s also a usage requirement that’s easy to miss: you need to close the battery compartment door properly, otherwise it may not be able to start the camera.

Key features (the bits that matter)

Quick overview

At its core, you get three parts in the pack: an AC-PW20 AC power adapter, a UK plug power wire, and the NP-FW50 dummy battery, plus an instruction manual.

The power side (what you can expect)

The kit specifies an input of 100V–240V AC, 50–60Hz, and an output of 8V 3A. It also claims multiple safety protections such as over-voltage, over-heat, overcharge, and short circuit protection.

In day-to-day use, these protections are reassuring “on paper”, but they don’t replace good practice—use it as intended, keep the adapter somewhere ventilated, and don’t force connections.

Where it shines, and where it may fall short

Where it shines - Continuous power for video, livestreaming, or any scenario where battery endurance becomes a hassle. - Reduces interruptions from sudden power loss during longer sessions. - Practical for home/studio setups, including when your camera is mounted and you don’t want to keep swapping batteries.

Where it may not be the best choice - If you shoot mostly on the move and for shorter clips, you may prefer a standard battery workflow instead. - It’s not suitable for the explicitly excluded camera models, so a wrong-model purchase is a genuine risk. - You’ll still need to follow the “close the door” requirement, otherwise, the camera may simply refuse to start.

Who it suits (and who should be cautious)

It makes sense if you own a compatible Sony camera from the listed ranges and you want a steadier power setup for filming and livestreaming, especially when you value fewer interruptions.

It may not suit you if: - your camera model is one of the ones listed as not supported - you mostly rely on handheld, travel, or short sessions where mains power isn’t practical - you’re looking for an all-purpose adapter for any Sony body (this one is clearly targeted)

Should you buy it?

This NP-FW50 dummy battery and AC-PW20 AC adapter kit is worth considering when continuous power is the main problem you’re trying to solve—live streaming, longer videos, and “set it up and let it run” situations.

Skip it if your Sony camera is in the list of excluded models, or if your shooting style doesn’t realistically benefit from mains power. Also, double-check before you order that your camera compartment door can be fully closed with the dummy battery in place, because that small detail is specifically called out as necessary for the camera to start.

If you’re buying to streamline a studio or desk setup, this is the kind of accessory that can make your workflow feel a lot less fiddly than repeated battery changes.

Mini FAQ

What camera models is this kit described as compatible with?

It’s stated to fit a range of Sony Alpha ZV-E10, A6000/A6300/A6400/A6500 (and more as listed), plus NEX series models. It also lists specific models it is not for—so it’s important to compare your exact camera name.

Is it suitable for livestreaming and video recording?

Yes, the kit is positioned for video, broadcast live, vlog-style shooting, and similar continuous-power use cases.

What power does the adapter provide?

It specifies an 8V 3A output with a 100V–240V AC, 50–60Hz input.

Does the battery compartment door need to be closed?

Yes. The instructions explicitly say you should close the battery compartment door, otherwise the camera may not start.

Is this kit safe to use with the camera?

The description claims protections such as over-voltage, over-heat, overcharge and short circuit protection, but you should still avoid using non-matching adapters and follow the kit instructions.
