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.

now have 6 lamps with almost identical function and size to this lamp, so I will refer to my experiences with those lamps for comparison. This is a small battery LED (bi-color and fully RGB) with probably the coolest design of all the lights I have, and very simple operating modes. This version of the light is stealth black on black on the back so if someone tries to use it the first time it's hard to read what each button does, but it looks cool and doesn't have the bright white paint if that happens in the picture. I would like the scrolling of the buttons to provide faster action (e.g. it takes a while to scroll to 100% or to 1%) and I feel like the brightness isn't as strong as some of my other similar lamps, but the color temperature measures very accurately and the battery seems to last very well. I have pictured the LEDs at 4000K with 1% brightness to show the number of LEDs and arrangement. I've owned MANY K&F products over the years, including tons of ND and VND filters, tripods, etc., and these lights fit the same high-end build quality as the other K&F products. There are two magenta on the back that you can slightly see through the transparent back. They hold REALLY well on nice flat metal surfaces, but even on a round post they can hold if placed properly. It comes with 1/4 20 screw holes on the top and bottom, and a 1/4 20 cold shoe holder is included. It's worth noting that there is no cold shoe slot built into the lamp itself (for stacking lamps), so you'll need a 1/4 20 to 1/4 20 screw to connect two together. Not a deal breaker, but I often plug my lights in during storage to keep them all together. The overall performance is great, and the build quality and style (if that matters) can't be beat. These are beautiful lights!

really love this LED Light personally! When purchasing, I was just looking for an LED light for me to take better pictures in dim lighting conditions. But after receiving it, I immediately fell in love with it! IT IS SO CUTE! The package is like a tofu and I really like the design: big text on the back, and the orange-yellow knobs on the side. The knobs have clear feedback at each location and I can really see all the different light that I easily control! I was also surprised by the 21 interesting lighting effects. They are so vivid! I kept playing with it for an hour and the joy it brought to me was way more than just an LED light. It made my day!

This is not my first video light, and I’m sure this is a good video light. Color of RGB can be changed easily and the battery last relatively long, at least 2 hours as I tested. Will buy the second one if needed.

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

I’m going to order an other one. Love it. 3 different light power settings.

As someone who makes YouTube videos, I’ve accumulated a lot of little RGB lights over the years, but this is by far the coolest, I’ve seen. The overall design is similar to what you’re used to in that it has a CCT mode, RGB mode and some pre-set scene modes, but it’s the overall execution of how these are employed that really sets this little light apart from the others. The style is quirky and cool. It comes in a package that literally looks like a box of tofu. And where others would have boring buttons or sliders, this light uses giant knobs on the side have a fun retro-modern kind of vibe that actually work just as good as they look. From the bottom knob, you can switch it on, turn to CCT mode, RGB mode or the scene modes. The top button allows you to change the intensity of the settings in the various modes, i.e.: brightness, saturation, etc. And of course there’s a magnetic back and not one, but two tripod mounts - one on the bottom and one on the top. This is a really well-designed little RGB light that stands out in a crowded market place of similar lights. This light both looks great and works great - definitely would recommend.

This is a nice little microscope with a decent power range. The upper dial is for your magnification and the lower dial is for focus. The LED is bright enough to light up for what you are trying to view. They give you 5 prepared slides of insect and plant parts but would have rather being given a couple of blank ones. I would recommend this microscope for both children and adults.
