DC output: 8.4V / 8.8V DC step-down cable length: 60cmCompatible with: For Panasonic Lumix DMC-GH3 For Panasonic Lumix DMC-GH3K For Panasonic Lumix DMC-GH4 For Panasonic Lumix DMC-GH5 GH5sAC adapter not includedPackage include: 1 x Step-down DC Adapter Calbe 1 x DC Coupler DMW-DCC121 x Free cable (male to male) (DC drive cable, Customized production, Strict inspection,High quality chip,Efficient conversion rate.) Compare the dc step-down cable with the USB step-up cable: (1) The dc step-down cable can easily find an external power supply that meets the requirements and can provide a more adequate instantaneous power requirement for the camera shutter. (2) The USB step-up cable has high requirements for the mobile power of the USB power interface, which involves the supply voltage, the quality of the internal battery cells, and the discharge switch current of the board chip.Tips: General digital battery printed above parameters 7.2V / 7.4V labeled battery, it is the camera's minimum operating voltage, these batteries need to use 8.4V charger, full of power, charger 8.4V said no-load voltage, operating voltage and no-load voltage are two different concepts. External power used in the camera, You need to have enough power to supply, the camera is a load,the operating voltage is far lower than the no-load voltage.Therefore, the Camera adapter's no-load voltage is usually between 8V-9V (Note: the multimeter test is no-load voltage) ## Features - ★ Step-down cable:Input DC Female plug size is: 5.5mm×2.1mm/2.5mm,Please note the size of the output plug of the external power adapter: 5.5mm×2.1mm/2.5mm Male, Support most of the power adapter that output voltage is 12V to 24V, current 1.5A or above. - ★ In order to avoid the interface between the dummy battery and the USB cable, long-term multiple insertions and removals result in wear and poor contact. After removing the dummy battery from the camera, it is recommended that you do not separate the connection between the dummy battery and the USB cable. - ★ Some cameras require that the lid of the camera's battery compartment must be closed, After closing the lid, the camera can be turned on, For details, see the Manual illustration. - ★ Easily use your own 12V-24V power adapter. dc step-down cable is suitable for 12V-24V power adapters for some printers, surveillance cameras, car chargers, routers, monitors, etc. - ★ If you have any problem during using our product,you are welcome to contact us for further assistance.

I kept getting the battery can’t be used. I guess the 7.4 volts was too low for the GH5 and metabones combo. This little gadget solved that issue. I modified the DJI step down adapter to output 12v and put this in between it and the dummy battery. Now I can shoot all day long ### ⭐⭐⭐⭐⭐ Good way to power my GH5 *by D***D on February 29, 2020* I use this devices with a 12V battery to power my GH5 camera for longer recordings. This device steps down the power to the correct level. ## Frequently Bought Together - Step-down Voltage Cable + DMW-DCC12 DC Coupler DMW-BLF19 Dummy Battery fit 12V-24V DC Power for Lumix DMC-GH3K DMC-GH4 DMC-GH5 GH3 GH5s - AreMe 8K Micro HDMI to HDMI Adapter (3 Pack), 90 Degree Left and Right Angle Micro HDMI Male to HDMI Female Cable for Sony A6000, Raspberry Pi 4, GoPro Hero 7 and Other Sport Camera - SMALLRIG NP-F970 Battery 10500mAh USB-C Replacement Battery for Sony NP-F970 F750 F550, PD 36W Fast Charging, 3.5H Full Charged, with OLED Screen for Monitor, LED Video Light, Camcorder, Green --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/88367147-step-down-voltage-cable-dmw-dcc12-dc-coupler-dmw-blf19](https://www.desertcart.be/products/88367147-step-down-voltage-cable-dmw-dcc12-dc-coupler-dmw-blf19) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-04-27*
