I recommend purchasing to photographers or "video makers" who own machines and equipment that can take full advantage of the variety of ports provided. It is a product that can certainly be improved, but the performance seems quite good to me. Even if you're looking for a versatile solution, you really can't complain with this one from K&F Concept!

Since I've been doing more in the field of photography and video production lately, I really wanted to get a suitable power bank. So I ended up with the one offered here. I anticipate the result: She is great. The following can be stated: +Easy assembly +Great battery life +Works absolutely reliably +Great design +Good size +Very good workmanship +Ideal for lights +Is state of the art +Very good price/performance ratio I therefore rate the power bank with it the maximum score of 5 stars. Clear purchase recommendation!

I love these K&F Concept V-Mount batteries. I like the look, they are small and the info display gives all the information you need. The exact percentage is especially helpful. You can also charge them via USB C, which is very convenient.

I've been a big K&F Concept fan for a long time and most of my photography and film equipment consists of products from this manufacturer. So of course I was all the happier about this battery! It is solidly made and works wonderfully. You can always read the battery level through the clear OLED display. It has enough connections. The battery charges the cell phone camera or whatever is needed at the moment. I am very satisfied but feel the price is a bit high and therefore award 4 stars.

Hello, the K&F Concept VB99 Mini V Mount battery with 6700mAh (99Wh) and OLED screen is very well made and makes a great impression both visually and haptically. The battery has sufficient connection options and does not necessarily have to be attached via the V-Mount, I tested it with a video light and as a power supply for my EOS-R5 and could not find any problems, only the price seems a bit high to me, so I give it a good 4 Stars."

The VB99 Mini V Mount battery from K&F Concept is delivered in a very stable box, which is lined with foam on the lid and on the bottom. The manufacturer has included a leaflet with instructions and information, but unfortunately the language is only English. A charging cable is also not included in the scope of delivery. The black plastic housing is very solid and most of the connections are protected from splash water by soft rubber covers. The first thing I did was fully charge the battery. The capacity of the internal lithium-ion battery with a size of 6700 mAh is displayed with percentage accuracy. The OLED display is easy to read, but I would like it to be a bit bigger. The glossy black surface on the front is approx. 65 mm wide and approx. 60 mm high. The display, on the other hand, is only about 20 x 10 mm. The strengths of this device lie in the protective mechanisms such as overcharging, overvoltage or overcurrent. In addition, the internal battery can be charged even though a camera or smartphone, for example, is being supplied with power. I was able to quickly charge my smartphone via the USB-C as well as the USB-A socket. While the charging time via USB-C corresponded to that of my 220 V power supply, it was even a little faster via USB-A. Conclusion: very solid power dispenser with a sharp OLED display, but I would like it to be bigger. I'm not deducting a star because you can see this in the pictures before you buy it. I hope this review is useful

I have two of them for my BMPCC 6K, because the actual batteries are empty far too quickly. Works fine with this. A bit pricey compared to similar parts, maybe they will last longer.

It takes a long time to charge but holds the charge well. Used on a Sony fx6

does the job. It's basically just a battery, but it's very well made and very good value for money. Appears to meet the specified specification. The build quality suggests that longevity is not an issue. You will not regret the choice.

This is a very well made and compact powerful power source. Although designed to include a V-mount for use with professional cameras and power source requirements, there are many other uses where power is required. One of my uses for this power source, at least in the summer, is to potentially charge it from a simple 20 watt solar panel. (It charges quickly from a PD source I recommend, and uses many other high-speed charging protocols). I bought a solar panel from Amazon a few years ago and previously used it to charge a 5 volt lithium battery pack, which has worked fairly well in the past, but always experienced a slow reverse discharge when the light source (the sun ) , was very low or at night. I connected the K&F Concept to the panel and it worked flawlessly, there was no discernible power consumption when the light source was dim and insufficient to provide a charge. I assume this is because the K&F Concept is processor controlled. So it seems to intelligently disconnect from the charging source when the input voltage drops and reconnect when there is enough voltage to charge. It's winter, so the sun is weak, but it charged the K&F Concept by 3% in about 50 minutes. This small charge was able to increase my wife's Ipad Pro by 12%, which is not bad at all and shows the efficiency of the K&F Concept. In the summer I fly my remote control helicopter and usually charge it with my car battery via a special device that requires a 10 to 15 volt power source. The K&F Concept worked perfectly in a test charge with the 12 volt output socket and a plug adapter. I should be getting multiple charges for this, but will update this review once I can confirm this. Apart from regular phones, iPads, cameras, etc., this device will charge. I won't list the ports it has, it says so in the description, but I've read that some people don't understand how to charge it. Charging is done through the USB-C port, which is used for both charging and normal output, all controlled by the onboard processor that automatically switches the C-ports function. The only criticism I have is the very small size of the screen and it would be nice if more information was displayed e.g. B. the current flowing through. I also find the labeling on the jack very faint and difficult to see, but that wouldn't be a problem in use. For the pro photographer, the way it mounts and the ability to produce a wide variety of outputs, as well as the comparatively small size/capacity would help offset the high price tag, but there's quite a lot packed into this small box.
