Good value for the money. I have found many uses for this camara.

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.

If you're looking for a good all round inspection camera this is it....
I purchased this with specific task in mind:
1. Plumbing inspection and leak detection especially when the drain is clogged...
2. Automotive and light duty Truck repair - used it to do visual inspection inside cylinders on diesel engine valve, cylinder walls and piston.. I used it to locate hidden bolts while changing out cam driven distributor on 1994 Toyota Camry..
3. Home HVAC inspection on evaporator, condenser, and supply side air registers.

I am retired and no I am not a professional.. just like fixing things and the K&F Concept Inspection Camera is soooo much better than using an inspection mirror and a flash light....plus you don't have to climb over or under things to do inspections....My wife uses it to find things that she has dropped behind the washing machine, dryer or the stove...

Quality best inspection camera I ever own.

This is a high quality instrument with excellent image quality. First of all, the kit comes with a very nice, custom-fit protective case, which is always a plus, especially for equipment of this nature. The endoscope is easy to use, the menu system and user interface is simple and straightforward. It comes complete with a 32 gigabyte memory card (installed) and fully charged so you can start using it straight away. No USB charger is supplied, but a standard USB A to micro charging cable. It charges from any standard 5 volt USB power source, giving you many options including charging from a notebook or computer. It can be charged and used at the same time - which is another plus. I found the picture quality excellent. The five-inch IPS screen is bright and detailed. I own several inspection cameras of this type and this one has by far the best image quality. It takes photos at 1920 x 1080 (Full HD quality) and records videos at 1280 x 720 on the included 32GB micro SD card. (It supports memory cards up to 64GB) The most outstanding feature of this range is the ability to control the direction of the camera probe. This is a real game changer. If you've ever wrestled with a non-articulating scope to get it where you need it, you know what I'm talking about. It's always frustrating and sometimes just impossible to get where you need to go. The 210 degree swiveling probe (on one plane) solves this problem. A combination of the probe's direction dial and rotating the gooseneck cable allows you to reach places that would be impossible with a non-moving scope. The probe is 5 feet long, which covers most inspection tasks. Another interesting feature is that you can stream the image or video to another device via WiFi, although I found the screen on this one to be so good that you wouldn't need to do that to get a better look, but it's a nice one Function to be able to share what you see with others. This has all the features you would expect from a top quality inspection camera, you can flip the image for a correct "heads up" view, the probe LEDs can be dimmed or turned off completely. As I mentioned before, it captures both stills and videos, puts a date stamp on the images and more... Another great feature is that when you record videos you also record audio - so you can take verbal notes along with it do what you see for future reference. The Owner's Manual is a small 3-1/2" x 5" booklet with only 6 pages. It is clearly written and contains all the necessary information. As I mentioned earlier, the interface is simple, so you don't need a book or an engineering degree to use it. I'm excited about this device. It is technically mature and well thought out. The fit and finish is top notch, the controls work well and the screen is fantastic compared to most. Sure, you can find cheaper devices, but this definitely proves you get what you pay for - a quality tool that's fun to use.

This is great for travel & home & vehicle. It is accurate, the humidity is useful & the Carbon Monoxide detection is literally something that could save your life anywhere. The temperature is great especially at hotels that you can't set it to a number. When you can set it to a number (Celsius or F it accurate for both). Put a magnet on it for my magnetic mount in my car if needed but use it mostly for travel. Wish it was USB-C charging instead of micro-USB but not a deal breaker as so many of my other stuff is micro-USB. This is extremely useful so far for travel love it.
