PERFECT LONG LASTING

A super convenient V-Mount battery! The product comes well-packaged, and they even include a USB-C to USB-C cable.The build quality seems solid—comparable to, if not better than, my SmallRig VB99.It also fits perfectly on my rail rig backplate and my QD (SmallRig) plate. While it’s a bit bigger than some competitors, it’s not enough to be annoying or interfere with any operations.The display is great—bright and easy to read—so I can clearly see how much power my rig (FX3) is using over time.If I’m just running the FX3, I can get about 5–6 hours of internal recording. Using an A7III with an external monitor and recorder (like the Atomos Ninja), it lasts around 4 hours when constantly running and recording.My takeaway so far: this is a solid alternative to SmallRig batteries, offering similar features and decent build quality, but at around half to a third of the price if you catch it on sale.Honestly, I’d rather buy three of these and take the chance that one might fail than spend the same money on a single “premium” V-Mount battery.Happy filming :)

I needed an external battery for my video system. I have purchased K&N products before and their products are really high quality, when I saw this battery I gave it a shot. It works perfectly. I have ran my video camera for a full day shooting off and on and still have plenty of battery. The design is perfect and the display is crisp and bright in the sun. I have had this battery now for a while and I have used it for so many different functions, such as charging my camera battery, phoned and small LED lights, this is a powerful battery well worth the investment. No issues and charging has been rather fast. However I have not timed how long it takes to charge, it just seems to chart quickly. Great battery, I recommend this to all my friends.

I started of my V-Mount journey with a larger (dimensions) Neewer V-Mount with many ports but only one USB-C. I've now relegated that one to powering my portable key light. This battery is so nice, works well, is smaller with the same capacity, and has two USB-C ports.I'm trying to think of anything I won't be able to power on a run-and-gun rig. I'm currently powering a Sony ZV-E1, Viltrox D550 Pro external monitor, Ulanzi CU01 Thermostatic (new) fan cooler on low, and a wireless mic receiver. I just finished 5 hrs and and it still had 20% left.

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.

I was very happy at first but had to return it within a week. I do not recommend.

Really enjoying this. Built very well and the screen read-out is super handy for knowing what is charging and how fast it's charging.Only issue I could mention is that the USB-C ports aren't on individual circuits, so if you plug in a new thing to an empty USB-C port, when you already have your camera with a dummy battery on the main port, the battery will drop connection to the camera (killing your recording) as it re-negotiates the charge with the addition of the new device. Slight bummer but not a big deal, just something to keep in mind. Also wish the screen was a bit sharper.

I love this V Mount. I can't believe how well it manages power. It feels solid and well made in hand. The battery lasts forever and the display is better than most others I've seen. I primarily use it for my video rig, but recently had to use it to charge my MacBook Pro in a pinch, and it had it up to 55% within minutes. It also just looks really really good lol. Beyond impressed with what K&F did with this V Mount.

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.
