Here you get a powerful V-mount battery. You should be able to operate pretty much anything with the output voltage. Unfortunately I still have a problem with my LED lamp. But that's not because of the battery. After all, I can now operate the LED light with the battery up to 80% brightness. I need to get a different cable. We sometimes had an output power of 15.9V but my light just doesn't like it (but it's a special case). In my opinion, it can actually provide the 16.8V shown on the product photos. With USB-C and the right cable, 20V at 3.25A is achievable. Otherwise, the photo camera and video camera are all operated without any problems. The battery can be charged very easily via the various power connections. The easiest way, of course, is via USB C. But here too - you need a smart power supply and cable. Otherwise it won't load fast enough! Alternatively, there are charging plates for V-mount batteries. Here you can get the electricity you need quickly enough. The V-Mount can also be used as a power bank for mobile phones etc. But that's only on the side. It is mainly used for video cameras and there are LED lights in which you can plug your V-mount battery directly. Of course I can't say anything about the duration yet, but for this price it should still be of good quality. If something were negative, I would write this as an update in my review. The price is generally steep, but you get a powerful battery. 6700mAh cannot be dismissed out of hand and that simply costs money. The 20V with 3.25A more justify the price, which is currently around EUR 319 (12/2022). There are also a lot of connections available. Not all V-Mount batteries have that either. The LED display is of course another nice feature, but not absolutely necessary. Still very nice.

Since I've been doing more photography and video production lately, I really wanted to get a suitable power bank. That's how I ended up with the one offered here. I'm anticipating the result: she's great. The following can be said: +Easy installation +Great battery life +Works absolutely reliably +Great design +Good size +Very good workmanship +Ideal for lights +Is state-of-the-art +Very good price/performance ratio Therefore, I rate the power bank the maximum score of 5 stars. Clear purchase recommendation!

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.

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.

So the picture or video quality was great, even from the inside camera you could see something behind the rear window, great during the day almost all license plates were recognized and at night it was also usable. For me the parking mode was important and I had, as some people
say Tried with a power bank because the car battery doesn't last long anyway, but if you live on a busy street, the dashcam even drains a big power bank after half a day, so it didn't record anything at night, otherwise I have to say that was
it The quality of the dash cam is good, but you should also get it for the price

am very happy that I can share my wonderful experience with this backpack. It's not just laptop backpack, for me it's more than it, this backpack saved my laptop in haevy rains. The design is very cool and the color combination used in this backpack design is very impressive. The highlight of the design is the power bank pocket, this backpack has a power bank pocket and this is a very useful feature for me because I don't need to carry a power bank in my hand. It has so many useful pockets so I could carry all my necessary stuff like books, pens, laptop mouse. Another great thing I found about this laptop backpack is that I have a 17 inch laptop so it is large compared to other common laptops although my laptop fits easily in this backpack.

If you turn on the IR illuminator and turn off the viewer, you think the entire device is off...but the IR illuminator is still on!!!!! You can power the device with a power bank via a USB cable to carry less weight and ensure longer runtime.

I have 2 cameras and several lenses, power supplies and 2 tripods, I also have a computerised mount for astrophotography. It All fit! As we know it is the horizon that can make or break a "star show" this will allow me to travel off the beaten trail for those "places" of wonder.As far as cons... well if you need speed to get your camera out the front pack can accommodate this. it is a bit bulky for action shots however if you landscape its good for one of the smaller wide angle lenses, diameter is limiting however, and fits my Nikon with a mounted lens quite nicely.
