I have many V mount batteries, but this is the only one I own which has a metal body. While I'm not likely to drop and break a battery, it is nice to know that there is some strength to the construction, which also doesnt add a significant amount of weight. The battery seems to last as long as my other similarly sized batteries and it charged plenty fast. The battery has a nice color display which shows capacity, battery state, error states and power consumption on each of the outputs, of which there are many.

I own many K&F products, but this is my first battery and so far the quality of this battery is as good as everything else I own with the K&F name on it.

Nice quality, good value.

Very nice battery with plenty of capacity, fast-charge capability. The display is nice with precision of charging and usage status. Since air travel limits the capacity and they don't let you check in lithium ion either, this is a good battery that you can still carry on yet have universal applications especially for pro use. Comes with a nice USB-C cord but no charging brick so bring your own.

The battery does what it's supposed to and charges devices that take usb-c, usb-a, d-tap, and 12v barrel connections. I really like the 240w cable they included (usb-c to usb-c) that includes a strap to keep it nice and tidy when not in use. I also like how there is a light on the back that you can turn on/off by holding down the power button for 3 seconds. I haven't seen this feature on a v-mount battery yet, so it's pretty neat to see them trying something new. The gun metal gray sides look pretty stellar as well and give the battery a nice look that's also different than the rest.

The only things I don't really fancy too much are the display readout and the main plug cover. The cover is a little difficult to get off of the plugs and then it just is in the way when you are trying to access the plugs beneath it. Perhaps this will get easier with use, but as of now it's a bit tricky. As far as the display goes, it feels outdated with large blocky text and doesn't display the readouts in real-time. I am glad it shows the voltage and wattage the port is using though.

All in all, this is a good battery, and I can recommend it. There are many choices out there though, and so far, I have not been let down by any of them (K&F, Moman, Smallrig, Neewer, and ZGCine). These batteries are useful for many things and worth the cost.

It doesn't seem to charge my cell phone any quicker than any other device, but it does charge it. The instructions are in an extremely small font, so they are hard to read. Also, there's little information about how to actually operate the battery (e.g., nothing on how to turn on the emergency light--hold the power button in for a while is the answer). The emergency light is pretty weak.

The display is good and you always know where you stand in terms of power and it doesn't seem to get hot while operating.

Had some issues hooking up a couple of lights to it, but it works well for a camera/monitor/etc backup to keep your devices running longer.

For camera gear by the time, you add up all the devices, each with their own battery, all it takes is for one of them to run out of a charge and your filming can come to a halt. Enter the V-Mount battery and you get an easy to use all in one battery source that gives you an reading of how much charge you have left. Not to mention that you can have more than one V Mount battery, or several of them, thereby giving you unlimited filming time.
It has multiple types of ports which are versatile and support simultaneous power for multiple devices like DSLR cameras, camcorders, monitors, smartphones, wireless video transmitters, tablets, laptops, and more. With this kind of versatility, it will be an essential part of my video creations.
The first thing you want to do is charge it up to 100%. Batteries in storage last a lot longer if they are fully charged. For a camera you will need a V-Mount to attach it to which of course is one of the ways it makes this battery more convenient. Overall, highly recommended.

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.

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.
