This is not an astronomy camera, it's a general purpose battery-powered, image-stabilized audio/video color camera. It communicates with your smartphone or tablet via WiFi. I dreagged out a rescued-from-the-trash 102mm el-cheapo refractor, clamped the camera on its eyepiece, and quickly focused on a fake windmill three miles away. I also tried shooting right into the low-angle sun glare in the ocean and the camera didn't blink (like I did)--the automatic gain control took it in stride. Mind you, the telescope made things seem close, not the camera--all it does is replace your eye. This is good because that means you can clamp it onto anything you might look through, such as a riflescope or microscope, or even just point it out the window. Set up is a little fiddly, but if you've hooked up a camera with its own WiFi hotspot it will be a snap. Select the camera wifi hotspot in your camera's settings and then use the app. In short, if you like cool stuff, this is well worth the money.

Used it for a week and it powered my Sony FX30 for whole day via USB C :)

This battery is brilliant. It powered a Blackmagic Pocket 6K for over 12 hours, shooting a mix of 6K 24 and 50. I finished the day on an 18% charge. game changer. No more box loads of NPF batteries

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!

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

A lovely pocket battery powered microscope it comes with travel bag, cloth and preprepared microscope slides. Good level of focus and zoom control means I can get a clear detailed up close view of things with my children.

light weight and led light vs warm light

I say this is the first battery powered camera I've bought. I was skeptical but pleasantly satisfied.
It is made of materials that are comfortable to the touch and feel sturdy in the hand.
Movements that can be controlled via the app are smooth and precise.
The battery lasts a long time, and the remaining power is more than sufficient even on days without sun or rain.
The clip to be attached to the wall facilitates installation, the same applies to the solar panel.
I can absolutely recommend the purchase! !
