V Mount Battery 50Wh 3400mAh Mini V-Mount Battery with 65W Output and TFT Screen, 2H Full Charge, DC, D-Tap, USB-C, USB-A for Camera Camcorder Video Light Monitor

I have several lights that have branded batteries which has always been a problem when you need multiples or when they wear out. If you buy extra of the branded (proprietary) batteries, they are only good for that particular piece of equipment. Batteries are expensive so the option of using V-mounts and cables instead of proprietary batteries has caught my attention.

I really like this battery for several reasons. First, the size is not so large and heavy which cuts down on weight. This is particularly helpful when I’m toting gear in a backpack as every ounce matters. Second, the display on this battery is easy to read and I like that I know precisely how much power remains. The battery is made well and is of good quality. The ports are good and give good options. I believe it takes a couple of hours to charge, but I haven’t actually timed it. I have gotten several hours of use out of it, but I really think that would depend on what you are running. For me, it lasts during a normal video session and then I charge it that evening for the next day.

I really appreciate that I can charge whatever I want with this battery and it has been used for monitors, lights, and a tablet. I have not experienced any heat issues with the battery. The price point seems fair and I would recommend this battery.

Why did you pick this product vs others?:
Heavy duty powerhouse is how I think of my one and only V-Mount battery. I originally got it for my mirrorless camera, but I sold it. Now I’m using it for my IPhone 16 Pro and it handles it perfectly and charges quick. It does add bulk and weight to my cage, but in a good way. It helps with stability from little micro jitters. I can power my IPhone and any accessories attached to my rig with this one V-Mount. All I need now is the V-Mount plate to make it look more professional. It is worth the price.

The product comes in a nice, classic K&F packaging.

In the box, you'll find:
- V-mount battery
- Charging cable
- Instruction leaflets

I won't go into the technical specifications since they're already extensively covered in the product description, but I'll share my experience and impressions.
Upon opening the box, we immediately notice how well-assembled the product is and how well-chosen the materials are, with much of the casing being made of aluminum to fully dissipate heat. On the front, however, a glossy plastic cover hides a color LCD display for monitoring parameters.
Connections include a V-mount, USB-C, USB-A, D-tap, and a 12-volt output.
The product's maximum power output is approximately 50 Wh, which is enough to power a rig with a camera and external screen (like in my case) or 50/60-watt lights.
I tested the product and was satisfied with it. It doesn't tend to get too hot during use, and even with high-drain equipment, the heat is well dissipated. Its battery life is remarkable, but the power output doesn't allow it to be used with 100-watt COB lights. However, it's excellent in the ring for powering an entire photography system, including screens and accessories. It's also a great ally when your equipment is running low or if you need a stable 12x output, as in my case with several homemade LED lights for mobile use.

It charges quickly, taking about two hours with 65-watt chargers, and once fully charged, it can easily power a MacBook Air for mobile editing.

I also used this battery a second time, using the 12-volt output to power VHF/UHF amateur radio equipment, and again the product proved to be excellent (long listening time).

In conclusion, it's an excellent product. Not suitable for high-power lights, but effective for everything else. My final rating is 5 stars.

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.

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.

While you won't get as many hours out of this as other larger capacity batteries, what you lose in hours, you'll gain in weight loss! I use this battery on my DJI Ronin SC2 gimbal to charge my Camera, wireless transmitter, and my phone. I can get about 5-or-so hours out of this battery on a full charge while powering those three devices, so it definitely serves my needs. I usually just toss it on a charger between shoots so that I can keep it topped off if it dips below 50%. While that's not the greatest for the battery's longevity, that's only when I really need it at full capacity. I love the digital screen on the side, so I can see quickly how much charge is left. It has a very secure attachment, and I never felt it lose connection or had any issues that way. I could pull power directly off the battery while also pulling power through my V-mount plate, and it took it like a champ! Love this thing!

This is a great V-mount battery for the money. The capacity claims seem highly accurate. It is significantly lighter than my old V-mount battery of the same capacity.

The build quality is strong and sturdy. I feel like I will get many years of use from this battery.

The build quality of this battery is fantastic. I ordered this to use with my DSLR, but I didn't realize I needed an adapter to make this battery work. The price point of this battery is great. Since I do not have the adapter needed to use this with my camera, I have been using it as a battery bank for other devices. It charges my phone quickly, and I can use this to charge my camera batteries as well. The camera battery charging is limited by the charger itself, but it charges just as quickly as if it were plugged into a wall outlet. The battery is small enough to carry in my camera bag. It is heavy, but it is also a beast of a battery.

Overall, the battery functions well, even though I am not using it as intended. The battery life is excellent, and the battery pack itself charges quickly relative to the size/capacity of the battery. I wish I had the adapter for my camera (i don't have one yet as it is 4x the price of the battery pack) as I am sure it would last for an all day shoot without having to replace batteries.

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.

This 3400 mAh battery has proven to be a truly useful and versatile accessory. Its compact and aesthetically pleasing design makes it convenient to carry and easy to integrate into any technological setup, whether for personal or professional use. It can charge virtually any device, from notebooks to smartphones to camcorders, making it a practical and multifunctional solution for those always on the go.

One aspect I particularly appreciated is the integrated TFT display, which provides clear and detailed information on battery level, output voltage, and power output, allowing you to accurately monitor the device's status during use.

This battery can be considered a true power bank, 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 ensure a stable and secure connection, perfect for ensuring uninterrupted power even during the longest shoots.
