DMW-DCC12 DMW-AC8 AC Power Adapter Gonine DC Coupler Charger Kit Compatible with PANASONIC BLF-19 Battery LUMIX DMC-GH3 DMC-GH4 DMC-GH3K DMC-GH4K DC-GH5 and Sigma SDQ SDQH Digital Camera.

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 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.

Not that great

まだ一度しか使ってないですが、問題なく使えてます。約2時間の配信ライブで使用しました。間40分は録画RECしましたが、電源が落ちる事はなかったです。まだ試してないですが、これで2時間連続で落ちずに録画出来れば、最高ですね。

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