I was worried that this battery would self-discharge in a few days if I didn't use it, but that didn't happen. It retains the battery 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 display and being from a well-known brand; you can trust its surge protection.
I've been keeping it fully charged in a backpack for emergencies since the day of the blackout, along with a radio that charges with the sun or a hand crank and allows you to plug in other devices to recharge them (like this battery). I take it out every so often to check it, so I know I'll never be left with a dead phone in a situation where there's no power.
It's designed to be attached to professional camcorders and camera lights, which is also very useful for specific occasions because I'm studying at a theater and on-camera acting school.

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.

The super practical and versatile little battery for professionals who are always on the go
The K&F Concept 50Wh Mini V-Mount Battery KF-V50 is great for those who work with medium-sized equipment like cameras, screens, or LEDs. With its 50Wh capacity and ultra-fast 65W charging via USB-C, it's compact, has a TFT screen to see where you're at, and multiple outputs to accommodate everything. Perfect, you need to have all of this at hand.
What we like:
- It works with a wide range of equipment thanks to its V-Mount format and its USB-C, D-Tap, and USB-A outputs, so you can plug in lots of devices at the same time.
- Express charging: with 65W Power Delivery, it fits quickly, which is practical when you're always on the go and need to get going again quickly. - Clear TFT display for checking battery status live, especially useful when shooting to avoid running out of battery.
- Safe: It prevents overcharging, short-circuiting, and overheating, so there's no need to worry even in difficult conditions.
- Compact and lightweight: Smaller and lighter than traditional V-Mount batteries, easy to carry while still being efficient.
What we don't like:
- Not very powerful for large, power-hungry gear: If you have high-end cameras or large projectors, it might not last long; you'll need to carry several batteries.
- Limited battery life: With its 50Wh capacity, it's perfect for short sessions or as a backup, but for long shoots, you'll need to bring several.
In summary:
The K&F Concept 50Wh Mini V-Mount is a great option for professionals who want a small, reliable battery that's easy to carry and recharges quickly. On the other hand, if you're working with high-power equipment or for long sessions, it's better to have a more robust battery. This one will be ideal as a supplement, always ready to go to give a helping hand. Far from being useless, it's the ideal complement on a shoot.
