Please see attached video review for unboxing and initial assessment. The product charged easily via USBc. I did not realize that this battery is designed for certain types of cameras - ultimately I found someone with access to that type of device and it worked flawlessly. It also charges other devices without issue and very quickly. No reservations recommending this product.

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.

This V mount battery is a powerhouse for any serious videographer. It has a huge power reserve, keeping your equipment running for extended periods. The LED screen is a handy feature, providing clear and easy-to-read information about the battery status. With multiple outlets, it can power various devices simultaneously, making it incredibly versatile I used it to charge my phone most of the time and it had multiple charges in it. This battery is a reliable and essential addition to any professional setup.

Impressive entry into the V Mount battery field

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.

This battery is an absolute beast. It has several ports to run different accessories at the same time, and is perfect for all of my particular needs. As a matter of fact, if I'm being honest, it's almost too good for what I need. I'm not complaining though, because I know that I'll never have an issue with powering my lights, my video monitor, and even my camera with a dummy battery if I choose to. I use the D-tap for my camera monitor, while using both USB C's to run a light, and sometimes my camera. This is all done simultaneously, and easily monitorable from the display on the battery itself, where you can see the power output for each device. It has USB-C fast charging, and a pretty robust 6700 MHz capacity. It'll have no problem powering professional lighting equipment, professional video monitoring equipment, cameras, acting as a power bank if need be, and many other applications where power is needed. It's extremely versatile with a range of inputs, and nicely designed. The screen is color and easy to read, and gives you a great knowledge of your power drain. All in all, it's a fantastic V mount battery, and I would absolutely recommend it for professional videographers, and photographers. I usually find at least one or two bad things to say about a product, but I'm struggling to think of any in this case. It's an easy five stars.

Great features and value vs other brands

Very good product, even has a light on the back for mounting it in the dark.

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.
