[1' / 0.3 m] I bought this to be able to power my Canon 5D Mark III from the Ronin-S 12v 2a out port, to get a longer shoot time with the camera. It connects to a dummy battery or anything compatible with a female 5.5/2.5 barrel connector. The one I found is the Tether Tools Relay Camera Coupler for Canon Cameras with LP-E6 Battery. I already used it on a 2-hour shoot and the battery on the Ronin-S only used about a quarter of the power. It was a pretty active shoot with on and off recording throughout the shoot. I also did a test of the camera recording for about 2 hours total while moving the gimbal (as much as I could while still trying to get work done) and it still had 1 full bar and one bar started blinking. So, I would be pretty confident doing at least a 3-4 hour shoot or more with this setup on a single charge depending on how much time the camera is actually recording. I'm not sure I would last much longer than 4 hours of shooting with a gimbal anyway. I'll try to update the post once it gets put through a longer test. This was definitely a great addition to the incredible DJI Ronin-S.

[1' / 0.3 m] Well made as part of the BDS in the bag

[1' / 0.3 m] The Bolt flashes and battery packs already recharge pretty fast, but this makes it twice as fast, almost instant even on full flash, works perfectly!!

[1' / 0.3 m] The power boost using this to augment my speedlight recycle time was very impressive when attached to my Bolt battery pack.

[1' / 0.3 m] Small and very lightweight. Easy to calibrate, but sometimes have to remove battery to re-calibrate. The thin controller that goes with is brilliant.
And on/off switch would help. It’s tricky to figure out to push the battery to the side.

[1' / 0.3 m] D-tap end fits smoothly into my Hawk-Woods battery and barrel end is a snug fit into my FeelWorld Ultra Bright monitor so no worries about it coming out.

[1' / 0.3 m] Does exactly what it needs to do, but the new Design compared to the old one is actually pretty cool.

[1' / 0.3 m] This is ideal for the Godox AD360II or Metz 76 MZ-5 in that it reduces the time needed for your next shot.

[1' / 0.3 m] If you're in tv news and use mirrorless cameras on a shoot and you have a monitor attached you your gimbal, this cable will connect to your Anton Bauer battery and give your monitor all the power it need. I used my gimbal on a protest and we marched for hours and I was able to see my shots throughout the entire broadcast. I highly recommend using this cable to power up anything to maximize sufficient power for any shoot during an extended time period. A MUST HAVE FOR PHOTOJOURNALISTS!!!!
