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

Here you get a powerful V-mount battery. You should be able to operate pretty much anything with the output voltage. Unfortunately I still have a problem with my LED lamp. But that's not because of the battery. After all, I can now operate the LED light with the battery up to 80% brightness. I need to get a different cable. We sometimes had an output power of 15.9V but my light just doesn't like it (but it's a special case). In my opinion, it can actually provide the 16.8V shown on the product photos. With USB-C and the right cable, 20V at 3.25A is achievable. Otherwise, the photo camera and video camera are all operated without any problems. The battery can be charged very easily via the various power connections. The easiest way, of course, is via USB C. But here too - you need a smart power supply and cable. Otherwise it won't load fast enough! Alternatively, there are charging plates for V-mount batteries. Here you can get the electricity you need quickly enough. The V-Mount can also be used as a power bank for mobile phones etc. But that's only on the side. It is mainly used for video cameras and there are LED lights in which you can plug your V-mount battery directly. Of course I can't say anything about the duration yet, but for this price it should still be of good quality. If something were negative, I would write this as an update in my review. The price is generally steep, but you get a powerful battery. 6700mAh cannot be dismissed out of hand and that simply costs money. The 20V with 3.25A more justify the price, which is currently around EUR 319 (12/2022). There are also a lot of connections available. Not all V-Mount batteries have that either. The LED display is of course another nice feature, but not absolutely necessary. Still very nice.

PROS: • High capacity (99Wh) • Compatible with V-mount accessories • Durable build quality • LED indicator for battery life CONS: • The charging port cover may come loose over time. I recently purchased the K&F Concept 99Wh V battery holder and I have to say I am impressed with its performance. This battery has a high capacity of 99Wh, which means it can last for hours without needing to be charged. I have used it with various V-mount accessories and have not been disappointed so far. The workmanship quality of the K&F Concept 99wh V-Mount battery is also impressive. It is made of high quality materials that can withstand rough handling, which is great for filming on the go. A nice touch is also the LED battery level indicator, which shows me how much energy is left in the battery. However, the cover of the charging port can be a bit annoying. It tends to come loose over time, which can make it difficult to protect your charging port from dust and dirt. Despite this minor issue, I would highly recommend the K&F Concept 99Wh V-Mount Battery to anyone who needs a reliable, high-capacity battery for their V-Mount accessories. It's a solid investment that's worth the price.

That's pretty impressive. It is well made, robust and very compact for the power it can deliver and the way in which it can deliver it. It looks neat, but this cleanliness comes at a price as the screen is tiny and very difficult to read, especially at first glance. The information displayed is also the bare minimum and a few “nice to haves” are definitely missing. This is ideal for projects that take a while and gives you the peace of mind to focus on your work without having to constantly check the battery status. It is advertised for use with a camcorder camera, but has many more uses including phones, tablets, cameras, flashlights, lamps, laptops... and is an excellent addition. The battery has a V mount and is easy to attach. It has a variety of ports including USB-A, USB-C, D-TAP, 8V DC and 12V DC, all of which have dust covers. The lettering on the ports is tiny and difficult to see, especially in low light. It has an intelligent BMS chip, which means it can charge multiple devices with different needs at the same time, and that's pretty convenient. It also supports high-performance USB-C bi-directional power delivery up to 65W. It will be worth it for some people who need this standard equipment on a daily basis, but for a general amateur this is more of a nice touch than a need, and I am would spend my money elsewhere.

I've been using this battery for a while and I love it. The problem I had was that it seemed to overheat and wouldn't turn back on even when I put it on the charger. I contacted Smallrig and they responded immediately and ended up sending me a new one straight away. Great product and great customer service.

am a dedicated user of K&F Concept products for my video production company and recently had the opportunity to experience their exceptional customer service first hand. When using the K&F Concept VB99 battery, there was an issue where one battery stopped holding charge and the other charged slowly. As a professional who relies on reliable equipment, this has been an issue for my workflow. However, I contacted K&F Concept customer service (Alex was a great help) and was pleasantly surprised by the quick and efficient response. They recognized my problem and promptly provided me with two brand new batteries to replace overnight. This level of support and commitment to their customers is truly commendable. Despite this isolated case, I have to emphasize that I am still a big fan of K&F Concept and its products. Their extensive range of camera accessories has become a staple of my professional setup. In terms of build quality, design and functionality, K&F Concept consistently delivers outstanding performance. It's important to note that every product has occasional issues, but the way the company handles them sets them apart. K&F Concept's commitment to customer satisfaction and willingness to do whatever it takes to support small businesses like mine has earned me my unwavering loyalty. I have complete confidence in K&F Concept and its commitment to manufacturing quality products. The K&F Concept VB99 battery remains a valuable addition to my gear collection despite the issues I have faced. I appreciate their exceptional customer service, which reinforces my decision to support K&F Concept in the future. Overall, I highly recommend the K&F Concept to professionals and enthusiasts who need reliable camera accessories. With their world class customer service and wide range of exceptional products, K&F Concept has proven to be a reliable partner for my video production needs.

The processing of the V-Mount battery is really flawless, very high quality, robust and high quality. In addition, it is also really very compact for the performance it brings. This makes it perfect for on the go. In addition, he also makes a lot in terms of design and appearance. It really feels like a real luxury product. A truly essential piece of equipment, especially for filmmakers. So that you can focus on your work for several hours in continuous operation without having to constantly concentrate on battery consumption and changing batteries. It charges my Sony DSLR camera with no problem. Even if you don't have the time to fully charge the battery (which takes a little longer here), you can reach about 3/4 of the charge within a very short time so that you can continue working without any problems. In addition, not only cameras, but also all other accessories such as cell phones, laptops, tablets, etc. can be charged. The Mini V Mount battery is also designed to charge devices at the same time, as various ports are integrated, namely USB-A, USB-C, 8 ＆ 12 V DC and D-TAP. The battery performance is also really strong at 6700 mAh. A nice additional feature of this product is the LED display, on which you can always clearly see how full the battery is. Sure, the price is really high, but you get a lot for it. Quality has its price. However, I would only recommend it if you really intend to use all the ports and really want to charge multiple devices (possibly at the same time).

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

this charges quick and it gives me 4 hours easy it looks like It can give a lot more but I haven't been able to use it longer then that as far as strait hours. its very strong build doesn't look like it will go bad so quick. I love the fact has the screen at the rear and its simple to understand.

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.
