K&F Concept V Mount Battery, 99Wh Mini V-Mount Battery, 6700mAh 14.8V Support 65W PD USB-C Fast Charger, with D-TAP, USB-A, USB-C, BP, OLED Screen, for Cameras and Camcorders

Got this K&F concept battery to use on my Canon R6 rig with the Smallrig tiltable Vmount bracket, and it's an awesome addition to my rig.

Adding a Vmount to your rig increases the weight tremendously but can also help reduce some hassle, especially, if like me, you are using a monitor as well. My monitor is an OSEE T5, and it likes to absolutely chew through the Sony NPF style batteries, so I'm always changing them like twice on shooting days. With this Vmount battery, I can plug in a usbc-to-usb micro cable, and power the screen off it for the entire day no problem.

I have one other Vmount battery, and this K&F has some big advantages. One, it's smaller than the competitor in every dimension, which is great for cuttings some bulk. Two, the screen is much more useful and provides pretty much the easiest way to tell how long its going to last - a run time meter! This is so awesome and being new to v-mount, I didn't even know it existed. On the screen of the K&F, you can see both USB port voltages, the battery voltage and bars%, as well as the current runtime for the output you are using. I have not used this to power my camera or other accessories quite yet, but seeing that number is incredibly useful.

One complaint, which might be a USB restriction, is that my display refuses to work on a USBA-to micro cable. I'm not sure if this is because USBA can't resolve above 5v or what, but I have to use a C-to-micro. PD on the USB C port works as expected, and is very useful because to power an R6, you have to use that. Unfortunately with my current cable set, my display cable blocks my USB port on my camera, so I wasn't able to power both the camera and screen at the same time, but I'm sure that's possible with a cable change.

Overall for the price of this battery, it's awesome. I would say that you should refrain from dropping it, as you should with most camera gear, but the plastic on it does not feel super thick. The vmount has a plastic plate where it contacts the receiving end, and feels just fine. It's attached with 3 screws so if you do break it somehow, it could theoretically be replaced.

Charging this over USBC works fine and charges the battery up in some amount of time (I always charge the night before shoots so I don't really care). If you look at the screen while charging, it does actually show that the voltage resolves to 20v, so make sure you are using a PD-compatible charger to get maximum charging speed.

For shooting video and still photography in remote locations I need to use equipment and power sources which are of sufficient quality and operate reliably. This K&F Concept V Mount Battery is sufficiently versatile for a wide range of power applications and in my experience it performs very well.

It is supplied with an instruction booklet and is compatible with both mini and regular V battery plates enabling it to attach to a compatible camera or V plate used with a videography rig. It can also be used much like a regular power bank for charging phones and other devices. The outer casing of the battery is a carbon fibre effect. It has the standard V batt BP terminals plus two D-Tap in/out, USB-A out, and one USB-C in/out.

I especially like the presence of the OLED display which clearly shows charging status and information relating to the power outlets while the battery is in use. Voltage output and remaining usage time are present in the display based upon amount of power being used by connected devices. It has support for multiple charging protocols including PD, QC, SCP, PPS, and APPLE-2.4A.

It can be charged with a suitable power source using the USB-C input or by my preferred method using a dedicated D-Tap charging unit. It certainly packs a lot of power into a relatively compact battery which is capable of 99Wh, operating at 14.8V.

I have been using it to power field monitors, audio recorders, COB lighting as well as charging a range of portable devices. In summary this is in my opinion a very good quality Mini V battery which is reasonably priced when taking into account the very useful display, capacity and wide compatibility. Over the last few weeks since it arrived It has performed flawlessly and I am confident to recommend.

This battery is of the portable type, given the dimensions and the fact that it can be taken anywhere, even in the airplane cabin (Power under the maximum authorized), all with a really controlled weight. But above all the 6.7Ah at 14.7v nominal, although in practice it sends more than 16v on its D-TAP ports, allows a wide range of applications. With a USB - DC5.5mm adapter, or a regulator from the available 16v, we can power a large number of electrical equipment, like for me a homemade tube amp under 12v.
The very practical point for me is the display of the output voltage (especially with the number of supported charging protocols) which allows you to know how the charge/power supply will go, and especially the estimated remaining charging time.
In short, it is not cheap but the compactness and flexibility of use make it a good value for money.

The K&F Concept V Mount Battery is a handy power companion. It's this compact 99Wh mini V-Mount battery that's surprisingly powerful. I was impressed by its design – super compact but packs a punch with 99Wh. It's become my go-to for keeping my LED COB light powered up during shoots. The fact that it's small and mighty makes it a fantastic choice for on-the-go use. The various interfaces (2 D-TAP, USB-C, USB-A, BP) are handy too. Overall, a nifty and powerful little gadget for anyone into photography or video.

This battery is a marvel!

I do a lot of professional video shooting and the shots that need to be taken are - very often - far from power sources...

So I connect my device to a fake D-TAP battery, my auxiliary lights, etc.

This battery has not one, but two D-TAP outputs, a PB interface, a USB-C port (Pd fast charge) and a USB-A port. In short, everything you need for mobility and of course a V-Mount attachment to put it on standard supports.

So it is not very small if we compare it to classic power banks for the same capacity but on a camera it fits perfectly (and it is not exactly the same use).

It simplifies my shooting so much that even when I have access to a power supply, I use the battery to avoid running cables.

I knew K&F Concept well for the quality of its photo filters, but the same care is given to this battery.

This battery has a capacity of 670mAh with a voltage of 14.8V for a contained size. At the connection level we have a BP interface, a d-tap connector, a USB type A and type C. The first 2 are for the world of photo / video as well as the V mounting bracket. On the other hand, the USB ports can be used for any type of power supply, with an output power of 65W. The OLED screen provides clear and easy-to-read information on the status of the battery, its consumption and especially the remaining usage time, very practical.

The fit and finish on my sample is excellent. I see that other reviewers had an occasional issues with poor D tap sockets but mine are fine. I am using this product to power ham radio gear and am happy with the power available. I wish that I had found this a long time ago.

It has the usual quality feel and build of a K&F product, although you will require a v mount adapter to mount it to certain cameras.
Comes with a clear lcd display giving usb- C and A outputs , power button is easily pressed to power the unit on. But is also easily pressed to power it off accidentally !
I will be using it as a stand alone power source for charging , iPads and iPhone.
Not the lightest or smallest but is a solid piece of kit to have on your travels if you’re away from power for a long weekend and wanting multiple charges.
Overall a solid piece of kit but maybe rather pricey for what it is .
