K&F's V-Mount battery has a couple of advantages that you don't see among the competition at this price point. The first is a mostly aluminum casing, which is both stronger and helps keep the battery cool. It offers dual USB-C, with the second being 100 watts both out and in for faster charging than many. The TFT screen is bright and in color, which is nice but in truth there's not much to colorize in the voltage info. The side grips are large and feel nice. My one pet peeve is that they include a nice 240W cable, but no brick, and a 100W wall adapter isn't something most people have lying around. All in all, this is a very solid, thoughtfully-made offering by K&F.

Really enjoying this. Built very well and the screen read-out is super handy for knowing what is charging and how fast it's charging.
Only issue I could mention is that the USB-C ports aren't on individual circuits, so if you plug in a new thing to an empty USB-C port, when you already have your camera with a dummy battery on the main port, the battery will drop connection to the camera (killing your recording) as it re-negotiates the charge with the addition of the new device. Slight bummer but not a big deal, just something to keep in mind. Also wish the screen was a bit sharper.

I needed an external battery for my video system. I have purchased K&N products before and their products are really high quality, when I saw this battery I gave it a shot. It works perfectly. I have ran my video camera for a full day shooting off and on and still have plenty of battery. The design is perfect and the display is crisp and bright in the sun. I have had this battery now for a while and I have used it for so many different functions, such as charging my camera battery, phoned and small LED lights, this is a powerful battery well worth the investment. No issues and charging has been rather fast. However I have not timed how long it takes to charge, it just seems to chart quickly. Great battery, I recommend this to all my friends.

I think this is by far best bang for your buck battery. Have smallrig vb99se as well, much prefer k&f one. Battery hold longer and love dtap toward down side

Super fast charging via USB-C 100w PD! Been using with a built up mirrorless body and a Ninja V recorder. Couldn’t be happier (as happy as you can be with a battery! ) can’t speak as to it’s longevity yet and I really don’t like the gloss finish on the back.

I have number of v-mount batteries and this one is very impressive for its price range. It’s got aluminum casing and a nice informative screen that provides a lot of info. Compared to the Neewer ones, the screen is larger and easier to read and give it a premium feel similar to the larger SmallRig batteries I have. The kit comes with the battery, USB-C cable and a manual.
This unit is fairly compact and lightweight and charges very fast using when using PD 100w charger. Included USB-C cable is very good quality and handles the higher load without any issues. It performs similarly to the Neewer PS099E/EP batteries but due to it’s metal casing, it feels more sturdy. Added feature of built-in light, while, gimmicky comes in handy when working in low light conditions. Neewer has very informative display but it feels crowded where it’s easier to read on this one. It pairs well with Godox ML or Colbor W series lights and provides over 50 minutes of power at full brightness at 4300k which is impressive when on the go. It’s got plenty of connections to power USB devices and/or D-tap output. It supports PD 100 out, which makes this a great power bank when needed. Versatility and the quality construction of this battery makes this easy one to recommend. Highly recommended!

Unique Aesthetic, Nice Display, good features
Interesting grey metal exterior compared to so many other black plastic alternatives. It has a nice material-covered USB-C to USB-C cable rather than the plastic cables others come with.
There are two USB-C ports of which one is also input for fast charging. It also has USB-A and DV 12v under the same top tab. The tab does take some work to open if you cut your fingernails short. It should be noted that there's no DV 8v port as found on some competitors but I don't find that critical. That said some competitors only have a single USB-C port and having two is a plus. The D Tap port is on one side while the power button is on the other. The sides have a textured grip for easy handling.
The display shows a nice clear large battery percentage while some competitors only show much smaller numbers with a more complex display. That option is certainly available as you can see the voltage and wattage out of each port in use along with the overall percentage. It's nice that the input and output values for each port are printed on the battery as a reference.
While this is certainly a crowded market this is a well-featured different aesthetic alternative. The silver metallic finish may make it easier to spot in a crowded equipment bag. That can be a big plus in some working environments and it's priced competitively as well.

I used to use NP-F type batteries for my power purposes but once I tried a V-Mount battery I decided that was the way to go! I needed a new one for a different monitor and went looking. I was not aware that K&F Concept did one so when I saw it, I ordered it as I have always been pleased with the quality of other products by them that I own.
If you've never used a V-Mount battery before you may be surprised at just how big and beefy they are. This one is approximately 4.25" x 1.25" x 3" or 108mm x 57mm x 78mm and it weighs 1lb 6.4oz or 634g. It comes with a 40" USB-C to USB-C cable and a small user's manual.
The battery has all the usual output ports you would expect. There are two USB-C, one USB-A, one D-Tap, and a DC 12V port. Input is via USB-C1 or D-Tap. It appears well made and there is nothing cheap looking about it.
Pressing the power button brings up the current power level in the form of a green circle. Incidentally, if you long hold the power button it will also turn on a small LED light which is located on the back of the battery just below the V-Mount itself. It's not ultra bright but in complete darkness you could at least see where you are going.
In use this is a battery capable of most things you could throw at it. I will mostly be using it for powering a Ninja V monitor, but it could also be used to power a camera (with the right adapter), or even just as a power bank.
This battery can also provide 100W output which means that it could also be used to power something as demanding as an indoor studio light or an outdoor portable location light.
Overall, this is a powerful 99Wh battery that performs very well in use. If you are considering a V-Mount battery, then this is definitely one you should look at.
