Update review: after speaking to the support they were able to provide me with a replacement battery which did not have this issue for this reason I’ve updated the rating.

The K&F CONCEPT 50Wh Mini V-Port MF-V50 battery is a solid addition to my camera setup. The 50Wh capacity is enough to charge my iPhone 50% or run a smaller lighting kit for a while. Particularly noteworthy is the integrated TFT display, which clearly presents important information such as voltage and power. The wide range of ports (USB-C, USB-A, DC, D-TAP, BP) makes it very flexible and allows you to charge multiple devices at the same time.
The fast charging function with up to 65W via USB-C is a real plus point, as the battery is ready for use again quickly. It is compact for transport and is also well protected thanks to the robust aluminum alloy housing and PC. A minor shortcoming is that the capacity for professional video cameras or larger lamps serves more as a supplement and not as a main power source. Nevertheless, I am impressed by the versatility and reliability of the battery.

This battery with a capacity of 3400 mAh turned out to be a really useful and versatile accessory. The compact and visually pleasing design makes it comfortable to carry and easy to integrate into any technological setup, both for personal and professional use. It can charge practically any device, from notebooks to smartphones, to camcorders, resulting in a practical and multifunctional solution for those who are always on the move.
One aspect that I particularly liked is the integrated TFT display, which provides clear and detailed information on the battery level, the output voltage and the power delivered, allowing you to precisely monitor the status of the device during use.
This battery can be considered a true level powerbank, thanks to its reliable performance and compatibility with a wide range of devices. It is particularly suitable for cameras, thanks to the presence of charging interfaces such as USB-C, D-TAP and BP ports, which guarantee a stable and secure connection, perfect for ensuring power continuity even during longer shots.

I was worried that this battery would discharge itself in a few days if I didn't use it but it hasn't happened, it keeps the percentage from the last time I turned it on.
Its price is slightly higher than other batteries with the same capacity, but it has the advantage of having a digital screen and being from a well-known brand, you can trust its protection against overvoltages.
I keep it fully charged in an emergency backpack since the day of the blackout, together with a radio that is charged by the sun or with a crank and that allows you to plug in other devices to recharge them (such as this battery) from time to time I take it out to check it, so I know that I will never keep my cell phone discharged in a situation where there is no electricity.
It is designed to be attached to professional camcorders and camera lights, which is also very good for specific occasions because I study at a theater and acting school in front of the camera.

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).
