K&F Concept V Mount Battery 99Wh 6700mAh with PD100W USB-C Fast Charging, Mini V Lock Battery with D-TAP/USB-A/Dual USB-C/DC/TFT Display/Emergency Light for Camera, Camcorder, Monitor, Video Light

I've come to appreciate the benefits of having a large V Mount battery for many tasks. This K&F battery has 99Wh but is still relatively compact. It has the ports I need, including a powerful USB C 100 watt port.

This battery works perfectly with my video lights that take V Mount batteries natively, but also work with other lights I have that can be powered by USB C. This battery also has a secondary USB C port, but only PD 65W, which is still respectable. There is also a standard USB A port which can provide up to 24 watts. Having a good set of USB ports makes this battery useful beyond the standard photo/video applications and I find it useful in many different applications.

As an avid camper, this battery is also a fantastic power source while away from power. It's a great battery for charging cell phones, recharging camping lights and any other recharging tasks a regular power bank would do.

About the only negative I would mention is it only has one D Tap. Most V Mount batteries have at least two, and sometimes more, so this might be limiting to some professionals that require additional D Tap outlets. But for my purposes, I rarely require more than one at a time, but do need USB ports in addition to the D Tap, so it works out quite well.

I do like that the battery can also be charged by the USB C port, which is a nice feature. I also like the digital power level indicator, which is superior to the standard row of lights to indicate battery levels. Overall, I'm impressed with this battery and is another product from K&F that is working well for me.

I've got a number of V-mount batteries used for lighting between various brands. This K&F battery is a good value. Compared to my Neewer units, the screen is bigger and metal case looks more high tech. Charging is pretty quick when using a PD high wattage chargers. Also functions as a power bank quite well. Battery life is just under an hour when used with my Neewer video lights.

Well built, works great ,last long, good quality , what more can I say other than I just bought 4 more. Worth every red penny.

GREAT VISUAL DESIGN AND NO ISSUES WITH THE BATTERY ON SEVERAL SHOOTS.

IT IS A GREAT BACKUP FOR MY LAPTOP AND PHONE.

A lot of power in a small footprint.
What I think that could be improved is to have 2 D-TAP connectors instead of one but for the rest I like what they are delivering with this product.
I added images comparing with a Neewer and one generic with no name.

Working great on my FX3 cinema setup. The form factor is great. 99Wh is perfect for travel on airplanes. In addition, the actual shape, being a near perfect rectangle makes it fit very nice along other rig components and also allows it to fit in padded bags and foam cases easily.

The outputs are numerous and have been working well for a variety of accessories. The screen on the back has better resolution than my first 2 cellphones hahaha. Seems like overkill but it's useful for long takes when estimating your battery life.

Best part is probably the metal build. This battery is heavier than it could be if it was plastic but it feels like a tank. Very robust.
No faults thus far

This K&F Concept 99Wh V-Mount battery has a TFT display, and without anything plugged in, pressing the activation switch on the left hand side gets it to display the current state of charge. If the battery is being used to power something, a table is displayed with the voltage and the power drain in watts, along with the current level of charge for each outlet.
On the back of the battery is the V-Mount itself along with the standard configuration for charging it up on V-Mount charger or fitting onto a dedicated holder on a camera rig. Oddly, the V-Mount is made from plastic whereas they are normally metal. In addition, there is a small lamp that you can turn on by holding down the power button on the side for a few seconds - switching it off is the same again. This gives you enough light in a place where there is no lighting to see what you are doing and can be very useful.
On the left is the aforementioned power switch which just switches on the display. On the right hand side is the D-Tap socket which you can use for lighting or anything else that takes power from the socket.
On the top are: one USB A; two USB C sockets which including super fast charging (100W); and, a 12V DC socket. The lid for the D-Tap socket comes out and is on a little rod - rotating this takes the cover out of the way. However, the top cover has a different join and it doesn't let you move it as much and as a result, it gets in the way.
This V-Mount battery has a metal shell which makes it a bit tougher than the other batteries but it doesn't necessarily make what is inside safer as a result.
V-Mount blocks are a useful standard form for photography and lighting and this one is no exception.

I could honestly not be more impressed with this V-Mount battery from the always excellent K&F Concept (one of my favourite brands)

This is a beautiful looking V-Mount battery and whilst looks aren't the most important thing here you have to admit this one is an absolute stunner.

As far as connectivity goes this one does the lot, from D-Tap, Barrel Output, USB and USB-C so you can get stuck in and get your devices powered up from one battery when shooting which is the absolute ideal scenario.

It feels extremely well built and will obviously last a lifetime. The layout is logical too which you can't say the same about for other brands.

The connectivity is on the top of the V-Mount battery which makes connecting up whilst in the middle of a shoot extremely easy.

The digital screen though. That's such a great addition and you can see the power draw as you're going so you know when you need to recharge but with a battery with as much capacity and staying power as this one you should easily be able to go hours/full days depending on what you're powering up.

I'm using mine with my Sony FX3, a monitor and other accessories that I have running into it. I'm not using the D-Tap as a simple USB-C connection is perfect for my needs anyway.

It has a 100W PD power output which is remarkable, and even has a tiny torchlight built into it on the back where the V-Mount connection is! That's strangely a very very useful addition and I've already used it numerous times for helping see in challenging lighting conditions.

K&F Concept are now a premium brand in videography and photography and I've got to the stage where I trust their products implicitly before buying but it's always good to get them in your hand, test and use them, and confirm it for yourself that they've done it yet again.

What a great solid, brilliant and almost futuristic V-Mount this is. I shouldn't be this happy about just a battery but this one makes me smile a lot!

As far as VMount batteries go, I have a new winner for looks and function.

This is my fourth VMount battery and I am actually surprised by the little thoughts that have gone into the look and feel of it. From the fancy little animation of the LED screen, to the aluminium housing around the edges. This all screams of a premium product, which you do expect from K&F nowadays.

You get your regular outputs, USB, USB-C, DTap and a barrel output.

100W PD output is wonderful, normally these batteries will cap out at 65W.

I actually found the little torch light by mistake when I was playing with the power button. Just press and hold it and it'll fire up. Absolutely required in a dark studio when clamping your battery to the mount.

I couldn't live without V mount batteries these days, well I could but it would be much less pleasurable, and this example from K&F is up there with the best having a large capacity and a plethora of outputs.
Whilst my main use is to power cameras, monitors and studio lights - as seen here - via dummy batteries, this also makes an excellent emergency power bank and is capable of reviving everything up to and including a laptop.

I did receive this for free via the Amazon Vine program but will be ordering a second as I'm that impressed.
