Guy at work I bought it for says it works great

Solidly built V mount battery. Better than using a power bank, as it is easy to mount on your camera equipment and the electrical connectors are more rugged/suited for higher power.
The 100w fast charging via usb c is excellent, and gives you rapid turnaround time when required.
Multi output ports really help here. But for some, the inclusion of a second D tap outlet would be handy.
For most though, one will be fine. Looks great with its orange accents, and makes it easier to find amongst your equipment. The power display showing the various outputs and their power is excellent.
Small graphics, but clear and readable.
Having lots of usb ports, means this can also double as a regular power bank as well. Ideal for when you are away camping. The built in lamp is also very useful, for when there is no lighting to see what you are doing. Usual High quality K&F design, and excellent capacity.

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

Super fast charging via USB-C 100w PD! Been using with a built up mirrorless body and a Ninja V recorder. Couldn’t be happier (as happy as you can be with a battery! ) can’t speak as to it’s longevity yet and I really don’t like the gloss finish on the back.

Perfect customer service, and product highly recommended

I needed a solution for continuous and reliable power for my outdoor live streaming rig. After relying on power banks and camera batteries for some time, I needed a stable alternative so that I didn’t have to keep a continuous watch on numerous batteries and briefly take the camera offline to change them over. The battery is a good weight so helps to add some weight and balance to the tripod once evenly distributed. I coupled this with a V mount clamp (purchased separately) which fits onto 15mm rails. The battery arrived with around 80% charge and wanting to put it to the test I didn’t charge it before its first use. After 3 streams and around 9-10 hours of use powering a Sony A7 iii via a dummy battery (purchased separately), the battery is down to 39%. It’s been out in overnight temperatures for a good 6 hours at around 1C to 2C and so far operated flawlessly. The included cable is the perfect length for my rig and perfect to uninterrupted fast charging. I chose this battery as it was slightly less expensive than other brands at the time of purchase but seemed to offer more in terms of available USB C & A ports which needed. The screen is small, not the sharpest but high resolution it’s really not needed. It’s a colour screen and only for checking available power, anything greater would just add to the battery drain so perfectly adequate for what and how long it’s used for. So far, I don’t have any issues and would recommend if your looking for a similar solution.

Its so tiny i love it

<font dir="auto" style="vertical-align: inherit;"><font dir="auto" style="vertical-align: inherit;">It's great, thank you for the quality and the two USB Cs. I highly recommend it.

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.

This is a great value, especially when on sale. Quality is great, build is nice.

But the cheaper version from K&F display shows the run time based on your usage and this one does not. A pretty crucial function. Would be great addition to a great battery.
