AC Adapter DMW-AC8 Plus DC Coupler DMW-DCC12 for PANASONIC DMC-GH3 DMC-GH4 DMC-GH3K DMC-GH4K Digital Camera

Not that great

Measured voltage output was just over 8.9V, without load. Drops to around 8.1V with a good load, which is about the same as the actual battery's output.Worked without issue. Came nicely packaged.Doesn't get as hot as my old AC/DC adapter, which had one of its capacitors pop after about 4 years of continued use. I'm not sure what's in this adapter, but the old one had two cheap chinese 1000uF 16V low-esr capacitors for output filtering. I considered just replacing them, but figured I might as well just buy a better adapter entirely. Hopefully there are better caps in this one; I'd assume so. Time will tell.I put a few more RFI clips on the cable, to help lower any potential noise that might leak into the mic input; not sure if that's needed though. Just a few other commenters mentioned that being an issue, but the cable already came with one built in.I'll update my review if it ever breaks

I got the Gonine DMW-DCC12 power adapter for my Panasonic GH5, thinking that I would be shooting long conference sessions. I haven't done much with the conferences yet, but I have used the Gonine adapter for long-term time-lapse videos and for an animation project. For less than $20, it is the perfect way to keep the GH5 powered for extended times. The GH5 even has a little "trap door" for the power adapter's cable to pass through, so that the battery door can be closed properly. (You can see this in the photos I posted.)In the photos, I show the Panasonic GH5 set up to do an animation project. The camera is mounted overhead, pointing straight down at a table where the animation work is done. With the Gonine DMW-DCC12 power adapter, I can run the camera as long as I like, working for hours at a time without having to bother with swapping batteries. The Gonine DMW-DCC12 adapter is the perfect accessory for an application like this.I've now used the Gonine DMW-DCC12 adapter several times, and it has always worked flawlessly. It is easy to use, inserts exactly like a standard camera battery, and it is a steal at the price. I recommend the Gonine DMW-DCC12 power adapter for the Panasonic GH5.

I bought this to connect to my GH5 in the studio so I wouldn't need to charge batteries so often.Pros1. Works fine. Kept my GH5 powered on with no power fluctuations or random shut offs.2. Prices seem well made enough.3. Relatively cheap.Cons1. I wish the cables were longer. I had to rest the power brick part of this on my tripod, otherwise it just hung there. Not a huge deal.Overall, I would recommend this product. It works fine and really does save you a ton of micromanagement charging batteries if you consistently shoot somewhere with an outlet.

Very happy with it. Makes my GH5S intoawebcam for work at home. No batteries to worrie about. Plug and play. Great.

We record performances for my wife’s school and sometimes they go over and hour and a battery swap was required. Now that we have this, our only factor is how large of SD cards are in the camera. We’ve recorded over 3 hours straight with zero issues on the power supply. Would definitely buy again!
