I have wanted a D-Tap battery for my Fuiji GFXs, for a long time. I have owned the D-Tap attachment for a few months, but held off on the battery until I found one I liked. This one I really, really like.

K&F are a group that understand the appeal of quality for many buyers. Of course cost is always an issue, but I also want something that will last. This is the one. nThe battery has two USB "C" 3.0 PD ports, a similar USB "A" 24w out, a 12 volt out, a BP point for pro video, a 16.8v D-Tap out, and.... an emergency light - of course. And I don't know what special elixir they have in this battery, but it accepts a charge like sand accepts water - it was amazing to watch.

This battery is designed to meet multiple needs, and it does so with class. It will charge or power just about anything you have, and for me, those long time lapse sequences are set it, forget it, and come back in the morning. The battery is pro grade in every way, and I highly recommend it

Guy at work I bought it for says it works great

I think this is by far best bang for your buck battery. Have smallrig vb99se as well, much prefer k&f one. Battery hold longer and love dtap toward down side

This V-mount battery from K&F concept is feature rich with USB, DC ports. The battery appears to be competing against some other offerings in the market with feature rich V-mount batteries.
This particular one is competitively priced and its features are similar to the competition.

I've had zero issues powering the camera and field monitors.

I love this V Mount. I can't believe how well it manages power. It feels solid and well made in hand. The battery lasts forever and the display is better than most others I've seen. I primarily use it for my video rig, but recently had to use it to charge my MacBook Pro in a pinch, and it had it up to 55% within minutes. It also just looks really really good lol. Beyond impressed with what K&F did with this V Mount.

I have the Smallrig V99Pro and looked for an alternative. This was half the price and does the same thing. Love it

I wasn't sure if all V Mount batteries were compatible. I have only every used Rotolight's official batteries with my Aeos, so I am going to compare them some in this review.

While there are more pins on this battery, the ones Rotolight uses line up ok.

This battery is also smaller than Rotolight's and has an LCD screen.

It shipped to me fully charged. It supports dtap charging and usb-c charging. It also has a usb-c output and an emergency nightlight.

I found the port flaps to be very difficult to open. I had to use a small pry tool.

The included user manual has some pretty good detail.

Overall, I am quite happy to have learned that this battery is compatible with my Rotolight.

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.

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

IT IS A GREAT BACKUP FOR MY LAPTOP AND PHONE.
