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.

This is a nice v mount battery with a d-tap and two usb-c which I like. Powers and charges efficiently and lasts.

Its so tiny i love it

Another addition to Vmounts with USB C i love these. I appreciate the two USB C ports, the protective cover is a bit hard to open but thats a first world problem

C’est top merci pour la qualité et les deux USB C
Je recommande fortement

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.

Nothing much to add, it works and delivers as per the description. Feels really good built quality, so I expect to have it in my arsenal few years.
The only downside, not related to this specific product is it's tricky to find descent D-tap to USB-c adapter, also the dc jack is 5.5x2.5mm, and most dummy batteries seems to use a 5.5x2.1mm

Great battery at a great price. I bought 2 and will buy 2 more.
