Used it for a week and it powered my Sony FX30 for whole day via USB C :)

Power v mount battery that also looks stylish! Lots of good connections and LED display with a simple but good percent display - just the price... There's something else.

INTRODUCTION > The world of photography is full of accessories that offer a huge advantage in creating different photographic content. I certainly believe that accessories of this type are more suitable for those who do this activity professionally, rather than for those who want to do it for passion. The K&F Concept brand specializes in the production and sale of accessories for photography and supporting various cameras. HOW IT IS > Comes in a box containing the battery and an instruction manual. The plastic used is of excellent quality, the product is compact and light. Perfect for placement right next to the camera. The compatibility of the battery is extreme, this can be used with any machine on the market, even the older ones, with a few precautions.

For those with a V-mount, the comfort is second to none. Present an OLED display that shows battery level and output current divided by each connected port. An excellent choice for photographers and videographers who need reliable and versatile power for their equipment. For work, it is an accessory that cannot be missing. As for the battery capacity, I thought it was much higher, however, they prefer compact size and weight. As mentioned at the beginning, the price is very high and if you are looking for an emergency battery, you only need a power bank and save a lot.

I recommend purchasing it to photographers or “video makers” who own machines and equipment that can take full advantage of the variety of connections 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!

Excellent for powering my Ronin S3's camera via a V-mount. Fantastic and great design

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

Since I've been doing more photography and video production lately, I really wanted to get a suitable power bank. That's how I ended up with the one offered here. I'm anticipating the result: she's great. The following can be said: +Easy installation +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 Therefore, I rate the power bank the maximum score of 5 stars. Clear purchase recommendation!

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. They are a bit expensive compared to similar parts, but perhaps they will last longer.
