The magnetic adapter ring is a plus. You can even stack it with the ND filter. The case is also very durable and should be great for protecting my filter when tucked into my camera bag.

Overall I am very impressed with this filter. It's so satisfying how the filter snaps into place. This filter will definitely be a staple in my everyday camera accessories and I would recommend this to any amateur or professional photographer/videographer.

Got this K&F concept battery to use on my Canon R6 rig with the Smallrig tiltable Vmount bracket, and it's an awesome addition to my rig.

Adding a Vmount to your rig increases the weight tremendously but can also help reduce some hassle, especially, if like me, you are using a monitor as well. My monitor is an OSEE T5, and it likes to absolutely chew through the Sony NPF style batteries, so I'm always changing them like twice on shooting days. With this Vmount battery, I can plug in a usbc-to-usb micro cable, and power the screen off it for the entire day no problem.

I have one other Vmount battery, and this K&F has some big advantages. One, it's smaller than the competitor in every dimension, which is great for cuttings some bulk. Two, the screen is much more useful and provides pretty much the easiest way to tell how long its going to last - a run time meter! This is so awesome and being new to v-mount, I didn't even know it existed. On the screen of the K&F, you can see both USB port voltages, the battery voltage and bars%, as well as the current runtime for the output you are using. I have not used this to power my camera or other accessories quite yet, but seeing that number is incredibly useful.

One complaint, which might be a USB restriction, is that my display refuses to work on a USBA-to micro cable. I'm not sure if this is because USBA can't resolve above 5v or what, but I have to use a C-to-micro. PD on the USB C port works as expected, and is very useful because to power an R6, you have to use that. Unfortunately with my current cable set, my display cable blocks my USB port on my camera, so I wasn't able to power both the camera and screen at the same time, but I'm sure that's possible with a cable change.

Overall for the price of this battery, it's awesome. I would say that you should refrain from dropping it, as you should with most camera gear, but the plastic on it does not feel super thick. The vmount has a plastic plate where it contacts the receiving end, and feels just fine. It's attached with 3 screws so if you do break it somehow, it could theoretically be replaced.

Charging this over USBC works fine and charges the battery up in some amount of time (I always charge the night before shoots so I don't really care). If you look at the screen while charging, it does actually show that the voltage resolves to 20v, so make sure you are using a PD-compatible charger to get maximum charging speed.

It's pricey, but it's a lot smaller than most of your regular Vmounts and offers MUCH MUCH more features like easy and fast charging via USBC, Dtap to the battery itself and a whole lot more. It holds the battery very well and delivers power perfectly. I had no problems with it, but only used it to power my camera. I'm planning on trying to power a lamp and power my camera and monitor at the same time. You can get it cheaper, but I don't recommend skipping out on no-name brands. So you don't have to go for these, but if you're interested and they're on sale, I would 10,000% buy them again.

What an incredible battery! Whether it's to power your camera... a small LED light (I used it on a USB-C folding panel, nickel) or any accessory on a shoot (of course it charges a phone) it works really well! K&F becomes a real reference in this field

This battery is a marvel! I do a lot of professional video shooting and the shots that need to be taken are - very often - far from power sources... So I plug my camera into a fake D-TAP battery, my lighting back-up etc... This battery has not one, but two D-TAP outputs, a PB interface, a USB-C port (PD Fast Charge) and a USB-A port. In short, everything you need for mobility and of course a V-Mount attachment to put it on standard supports. So it doesn't have a very small format if we compare it to classic power banks for the same capacity but on a camera it fits perfectly (and it's not exactly the same use). It makes my shooting so much easier that even when I have access to power, I use the battery to avoid running cables. I knew K&F Concept well for the quality of its photo filters, but the same care is given to this battery.

For shooting video and still photography in remote locations I need to use equipment and power sources which are of sufficient quality and operate reliably. This K&F Concept V Mount Battery is sufficiently versatile for a wide range of power applications and in my experience it performs very well.

It is supplied with an instruction booklet and is compatible with both mini and regular V battery plates enabling it to attach to a compatible camera or V plate used with a videography rig. It can also be used much like a regular power bank for charging phones and other devices. The outer casing of the battery is a carbon fibre effect. It has the standard V batt BP terminals plus two D-Tap in/out, USB-A out, and one USB-C in/out.

I especially like the presence of the OLED display which clearly shows charging status and information relating to the power outlets while the battery is in use. Voltage output and remaining usage time are present in the display based upon amount of power being used by connected devices. It has support for multiple charging protocols including PD, QC, SCP, PPS, and APPLE-2.4A.

It can be charged with a suitable power source using the USB-C input or by my preferred method using a dedicated D-Tap charging unit. It certainly packs a lot of power into a relatively compact battery which is capable of 99Wh, operating at 14.8V.

I have been using it to power field monitors, audio recorders, COB lighting as well as charging a range of portable devices. In summary this is in my opinion a very good quality Mini V battery which is reasonably priced when taking into account the very useful display, capacity and wide compatibility. Over the last few weeks since it arrived It has performed flawlessly and I am confident to recommend.

I've been using the camera for a few weeks now and I'm quite satisfied. The solar panel supplies the battery with enough power. In my case, the solar panel is not exposed directly to the sun or only for a short time and the battery is still 100%.

The image quality is sufficient and the night vision is good for 2-3m. The motion detection works, but could trigger a little faster.

Unfortunately, the management of the recordings only works via the CloudEge app. Therefore, the camera cannot be integrated into any other systems. Anyone who can live with that and has no power supply available at the camera location is well served with the camera.

The K&F Concept KF50.0009AEU is an outdoor surveillance camera with full control via wireless connection. It is powered by an internal lithium battery that can be charged with the included solar panel. The lens mount is motorized and allows remote control of horizontal and vertical movements as well as zooming in and out.
The integrated power source provides some independence in camera location. I placed our sample on a post in the backyard, fairly high up, pointing at the lawn to record wildlife, especially at night. The plastic mount is easily attached with the screws provided. Masonry requires the use of a drill and dowels (preferably better than the cheap examples in the kit). I mounted the solar panel under the camera in a similar fashion, using the pivoting mount to adjust it so that it points slightly upward to harvest as much sunlight as possible. It could be placed away from the camera. The 3-meter tether offers a lot of flexibility in this regard. It plugs into a USB-C socket underneath the device. An alternative power source could possibly be used if sunlight is scarce, but the body of the plug is a bit too small and the socket is surrounded by rubber to keep moisture out, so a suitable cord is needed.
Before all this, the first task is to connect the camera to the home WLAN and download the Ubox app to a smartphone. It's pretty standard for this type of device. I would have liked to use the camera via PC, but it doesn't support Windows. The only option is to use the Android app in an emulator, or possibly use a Windows program with multiple factory cameras. This requires some knowledge and effort, and the camera may need to be set up in the manufacturer's app first to get the necessary details.
The camera can be set up with either a sound signal or a QR code. I had trouble with the former, but the QR code worked right away. The instruction book clearly made some effort, but some of the English language is difficult to follow.
The camera has all the typical features listed. The app is fairly easy to navigate, but not perfect. Recordings can be viewed after a short connection delay. They can be stored on an SD card in the camera or in the cloud (subscription required after the free trial). The recording quality is very satisfactory, and I found this camera generally capable. I'm still trying to set up shots longer than a few seconds, and the battery doesn't last the night at this time of year. It might be better on a safety setting where it's not triggered and not accessed as often.
