[V-Mount] I got this to power my Atomos Ninja V with a D-Tap to DC barrel cable. I am using a dual NP-F to V-mount adapter plate into this unit and then out. It also provides another D-tap and a couple of DC outputs, so I will likely get an adapter to also run my camera from the dual NP-F batteries.
Keep in mind this unit does have to be powered on, there are electronics inside and a small power button on one side. I thought something was faulty at first until I saw the button.

[1.35 lb] They came included with my lights so I can't complain, and even if I paid for them, they seem like good enough quality tho basic in functionality but that would be asking too much from them. Design and quality is also fair and they come on nice foam that you can keep to use as protection for transport.

[V-Mount] There's no reason to run a small COB light like that on AC power for regular field shooting. With two 6600 mAh batteries, I run a CL60 at 80 % for 1h45 min. Yes the D-tap plug is a bit loose but it's ok, the power indicator on the plate gives it a 5 stars. It has only for leds but the last one dims when the power gets low.

[1.35 lb] I had been working with a cold V-mount plate for a while (not using the pins at the bottom of the V-mount battery), and it became annoying to connect to and disconnect from the V-mount battery itself over and over again, not to mention having to ration a single D-tap port. This new battery plate gives me the ability to quickly swap V-mount batteries and power multiple devices at the same time, including devices that require USB. It's a real boon.

[V-Mount] I can power my camera for those long events or lights. Very useful.

[V-Mount] Came with 4 CTO filters that slide right into the Zaila and give you the option of intensity.

[1.35 lb] This adapter saved the day for a live filming. The build quality and reliability of the the adapter helped power my Blackmagic 4k G2 sitting on a ronin rs 2 as a PTZ camera. The crab shaped clamp makes it possible to attach to virtually anything making it great for all occasions.

[V-Mount] Even if you don't have a Colbor this is awesome to be able to use your NP-F batteries to power usbc devices

[V-Mount] Quality V-Mount plate, this V-Mount plate came as a add on to the SmallRig 120D LED I bought, it has D-Tap ports as well and I might just end up using this for many other of my V-Mount needs. Actually will buy a couple more of these as they are of Great Quality.

[V-Mount] I've used SmallRig stuff for years when the more expensive options weren't possible. Truthfully, some of the pricier competitors stuff hasn't served me as well as my SmallRig gear. I got this as a solution for V-Mount battery options to supply power to my Fresnel LEDs and it works as expected, allowing me to clamp it directly to the light stand.
