PERFECT LONG LASTING

Pros
Heavy duty power bank
Professional Quality
Fast Charges (in and out)
Good range of connections

Cons
Overkill for average use, but great for professionals

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.

Well made, feels premium

High capacity, easy to charge and use, multiple outlet ports.

As far as this goes it's good value for money, the functionality is great and I'm happy to call this 5 stars.

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.
