It is a powerful battery with a decent capacity of 3400mAh. A compact design that will make it easier to be carried around multiple other hardware tools.
Although mainly designed for video cameras, it does a good job at charging other devices such as smartphones, tablets or even laptops. The only downside of it is the battery capacity as it may not be big enough to fully charge certain high-end smartphones or even laptops.
The screen provides some information on battery percentage and other details about the current types and their voltage or wattage. Upon receiving my unit I have noticed that it was not charged at all.
Overall, it is a solid built v-mount battery that is also versatile and can work on many devices. Battery-wise I would have preferred a higher capacity given the price of £99 at the time of review (promotional price).

This is a pretty good battery. I like the design; the color of the case and the color display. Battery life is as expected with a battery of this size. The included USB C cable is a nice one - flexible braided cable with a nice hook-and-loop strap. My only concern was that the display cover wanted to come off when I peeled the protective plastic. The mounting glue may have been either weaker, warm, or simply not enough was used. I caught it before pulling more and was able to remove the plastic without pulling off the front plastic. Other that than, all appears to be fine.

This K&F Concept mini V-mount battery is like a power-packed energy bar for your gear. It's compact, efficient, and ready to go. The 65W PD output charges your devices swiftly, and the TFT screen keeps you informed about power levels in real-time. Its multiple interfaces (USB-C, USB-A, DC, D-TAP) mean you can juice up your camera, monitor, and phone simultaneously. However, the 50Wh capacity might not suffice for extended shoots. The design is AWESOME! I wish all my Vmount batteries looked as slick as this one. It's you're like me, an on-the-go creator needing a reliable power source, it's a solid pick.

I like that this battery comes included with a braided 240W rated USB-C cable; I can confirm that this USB-C cable can reliably deliver 65 watts to my video light that accepts USB-C power delivery. Functionally, the battery works and fits securely in my v-mount bracket adapter.
With the slimmer profile, I believe the tradeoff with this model is the shorter run-time and capacity; I have to mindful of the project length I have scheduled and if this battery will suffice. For shorter filming projects and portability, I think this battery makes sense.
As for charging the battery, I did see that this battery only accepts up to 45W input via USB-C; I was able to charge it to full relatively quick with my laptop OEM USB-C charger that is rated for 65W.
Construction wise, the materials used feel acceptably rigid and not too brittle; I did not see any physical damage nor imperfections with the finishes. I am not a fan of piano black plastic front which is a dust and fingerprint magnet; I am not sure how scratch resistant the plastic front is.

This battery was a good little investment into improving the workflow on my photo/video projects! The battery is small and compact enough to fit into my camera bags and has so far helped power my video lights using the USB-C connection. The screen is also clear and indicates how much charge is left in the battery whilst also indicating the power output.
I haven't run into any problems with charging the battery outside of my projects, and Haven't had any issues with the battery running out of power on location. From a full charge, I've been able to use the battery for about 3 ish hours and still had just under half power left.
A good little battery for anyone who needs to charge equipment whilst shooting on location. If this is you then I definitely recommend trying this out for yourself.
