K&F Concept V Mount Battery 99Wh (14.8V/6700mAh) PD100W Mini V-Mount Battery with DC/D-Tap/Dual USB-C/USB-A/TFT Display for Camera Camcorder Video Light Monitor V99 Pro

The battery is a powerhouse of a portable power solution. It's fantastic to have 99Wh packed into such a compact form, making it ideal for on-the-go video and photography work. The variety of output ports ensures compatibility with a wide range of devices. The TFT display is a great addition, providing real-time battery status at a glance. Compact yet powerful, it’s ideal for on-the-go shooting.

Having that extra bit of power when out filming is a game changer. It also can charge up other items. I love the visual display as that comes in handy. It has multiple interfaces with a wide range of connectivity. It is solid in construction and very high quality.

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.

This K&F Concept mini V-Mount battery has a capacity of 99Wh, making it airline-friendly. At 78mm wide by 109mm tall by57mm deep and weighing 643 grammes, it is pretty much the same as just about any 99Wh V-Mount block although this one has a metal sleeve around the front three quarters of the body in order to protect it from knocks. On the back, there is: the V-Mount itself - this one is plastic so I don't know how hard-wearing it will be; the BP connector block at the bottom; and, in the middle a light to see with, which is unusual although, potentially very useful in poorly lit situations.
On the front is a graphical display showing you the level of charge and when it is under load, it also lets you know the voltage and level of power going into any if the regulated sockets - that is to say that when using a direct connection such as the D-Tap, this does not show.
On the left hand side there is a push switch and with a short press, you see the display on the front but with a long press, you turn on the LED at the back - another long press turning it off. On the right hand side, covered with a water resistant flexible plastic cover, is the D-Tap connector which, on the review copy, was slightly misaligned at an angle, making it quite difficult to get the plug in there when compared to other blocks that I have, even though once it was in, it worked all right, supplying the the continuous 65 watts that I was drawing from it for a photographic light as you can see in the photograph.
On the top, again covered by a flexible plastic cover, is the main connection interface. In it are: a 12V DC connector (5.5x2.5mm); two USB C connectors - one labelled USB-C1 and the other labelled USB C2; and, a USB A socket. Of the two USB C sockets, the V-Mount blocks only seems to charge through USB C1.
Whilst the display shows you the voltage and the wattage for any active, regulated connection, unlike other V-Mount batteries, it does not give you an estimate of the amount of time left for the battery to run down. Also, although this in no way impacts on the performance of the battery, this is the slowest colour display I have ever seen, taking almost two seconds to replenish.
On the whole, this is a capable battery with plenty of connectivity and as all V-Mount batteries, it is very useful, whether you are running small studio lights from it, a camera rig or using it to charge your phone. The only thing it has against it is the poorly implemented D-Tap socket on it.

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

I bought this after seeing a friend have something similar - they had the popular Smallrig version, but I like the colour of this one (honestly, if something comes in funky colours, I'll buy it - whether I need it or not!)
I used this the other day filming 4k video on a Sony FX30 for a solid 4hrs and it only went down by 20%, so it's worth it's weight in gold for long days of filming!
It clicks nicely into a v-mount system, and has a perfect amount of sockets for my setup.
It'd be nice to have 2 d-tap plugs, but it's not something I currently need.

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

IT IS A GREAT BACKUP FOR MY LAPTOP AND PHONE.

What I do like:
The display. I was surprised to see that this charger has really become my go to for testing electronic devices. Yes, due to the heavy duty nature of it, it does get used for charging devices all over our home. But what I like about it is the display that will tell you what's happening with the charge that most devices simply don't address. This has become incredibly handy for testing. For example, my daughters tablet just stopped charging one day. I tried numerous dongles and cables and nothing. Thanks to this I was able to plug it in and see what was going on. Similar situation with a set of earbuds that I have.
Charges pretty much anything and will charge a lot before needing to be recharged itself. I think the advertised recharge time is also pretty correct. I would put it at about approximately 2-3 hours.
Build quality, seriously feels like a brick.

What I dont like:
My complaints are really a bit minor but one couldve been an issue. As this was nearing a recharge I figured Id plug it in and get it filled up. Sadly, I lost the manual and instead looked at the product page. Which shows C1 as being the in/out. This is incorrect. C2 is the in/out. C1 is for charging only. I had this plugged into an outlet for 30+ minutes and noticed that the battery level was going down... I switched ports and the display screen changed to a charging screen and off it went. I guess I was charging my house for a bit??? My other complaint again has to do with the product images which shows the port cover as being something that flips up. It does not. The charge cover is a rubber cap that doesnt attach to the device unless you're not using it. Its either on, or its off.

V mount batteries are some of my favorite batteries to use when i build out a camera rig. This battery is more versatile than all my other v mount batteries because it has a 100w PD usb-c port. This allows me to use this battery with some of my lighting equipment that requires up to 100w input.

The battery life is perfect for any of my builds as i have never fully exhausted a charged 99wh v mount battery in one sitting. It has 2 usb-c ports with high wattage support. USB-C1 supports the 100w PD and USB-C2 supports 65w, giving me more flexibility in my setups. It also has a D-tap port and a 12v port.

This is an amazing battery that takes V-mount to the next level for me.
