This V mount battery has proven to be an exceptionally valuable addition to my filmmaking equipment, offering a compelling combination of performance and affordability. Its price point is remarkably competitive, especially considering the features and capacity it provides.

One of its key strengths is its ability to hold a charge effectively, ensuring reliable power delivery throughout extended shooting sessions. It consistently powers my devices as expected, without any noticeable fluctuations or interruptions. While I lack the specialized equipment to conduct precise capacity measurements (and it's a common observation that many power banks and batteries don't quite meet their advertised specifications), my practical experience of charging my devices multiple times suggests that its actual capacity is very close to the stated amount. This reliability is crucial for professional applications where consistent power is essential.

The battery's form factor is another significant advantage. It's designed to be compact and lightweight relative to its capacity, making it conveniently portable and easy to transport to various filming locations. This portability is vital for on-location shoots where minimizing equipment weight is paramount. Despite its lightweight nature, the battery exhibits a substantial and robust build quality, instilling confidence in its durability and resistance to damage.

The charging time is somewhat longer than with smaller batteries, but this is an acceptable trade-off for the extended runtime it offers. The integrated display is a particularly helpful feature, providing real-time information such as voltage output, which is invaluable for monitoring the battery's performance and ensuring compatibility with different devices.

I've relied on this battery extensively for powering my camera and other gear during filming projects, and it has consistently performed admirably.

In conclusion, I wholeheartedly recommend this V mount battery as a reliable and cost-effective solution for powering professional video equipment. Its combination of strong charge retention, efficient power delivery, portability, durable construction, and informative display makes it a worthwhile investment for any filmmaker or videographer.

I got this battery as backup power mainly for my video lights, but I’ve used it with other equipment, as well. It works great. It charges up easily and lasts a long time. I’ve had no issues while in use. I like that it is V-mount because I can hang it on a light stand using a V-mount hanger and not have cords to trip over. It is built sturdy and feels durable. I’ve experienced no heat issues. The display is easy to read.

I shoot video mainly with my phone for interviews, but I also have a Blackmagic Cinema 4K and a Sony a7 iii that I use for video. I got tired of small batteries, and decided to look for a single larger battery I could mount to my tripod and run a cord for D-Tap to the camera.
This K&F Concept 99Wh Battery is a great find!
It uses a mini V-Mount plate on the back so I can clip it to a pipe/tripod leg mount securely and quickly. I have access to a D-Tap plug as well as USB-A and USB-C, and a DC out connector. Running a line up to my camera is simple and safe.
This supplies 99WH, which means you can take it on airlines in your carry-on bag. I made a copy of the instructions to bring with me just in case TSA wants to double-check the power rating.
I really like the clean display. I can check overall power percentage, and also get a breakdown of current draw across the DC and USB plugs if I have my phone or mics charging on the battery.
This has lasted me about 6 hrs, running my Sony and a light kit; I haven't shot as much as I had planned this past month, but I'm really liking this so far.
This K&F Battery is a great size. This is so designed for a travel bag there is no excuse not to take it with you!

I didn't expect much from this battery, but it proved to be more useful than I initially assumed.

I'm able to power various devices using this battery with no problem, it's quite powerful.

Something I really liked seeing on this battery is the emergency light on the back of the battery. It's turned on by holding down the power off/on button, and it provides a small light output which could save the day in an emergency scenario when no other lights are available.

Something I didn't like were the rubber flaps that cover the charging ports. I found it quite tough to get them out.

With that said, this is my favorite battery so far, and I really recommend it.

Recommended, I haven't had any problems so far.

This thing is a beast! Straight out of the package I've been running my FX30, Lilliput 7" field monitor, rode shotgun mic, and an occasional auxiliary light for a few weeks....I still haven't charged it! Maybe like 20 hours or so of actual footage time. But, still....it rocks! It is heavy, and a sizable brick.....but, I knew that going in. I could probably get by with a smaller version.... but, I like not having to worry if I have enough juice.

Great alternative and cheaper than the small rig v mount battery

Excellent power bank, I use it for my CANON R50V camera. I no longer have to worry about running out of battery when I record for more than an hour. It's a very practical backrest because I can power a bulb that I use with the camera

My order arrived quickly and packed well for the shipping. Everything seems to be working good, I haven't had a chance to really put it through its paces but so far so good.

I used this with my sony fx6 recording at 4k 23.98 for 2 hours straight with my osee g7 pro field monitor and it went from 100% to 62%... just amazing
