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!

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.

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.

Charged my 10,000 mamp battery bank in 3.5 hours in bright sun. Not sure of the durability or how it will work in overcast days. Purchased to use backpacking will see if it works clipped to pack or only at camp.

This solar panel works great when camping or hiking as you can charge power banks or usb compatible devices like iphones or android smartphones without a power bank. I prefer to use this in combination with a small power bank though to keep my devices topped up when camping for multi-day trips.

While it's built well and provides a good bit of trickle power when in direct sunlight, it is a bit heavy. Size wise it's comparable to an ultrabook or large tablet so ultralight backpackers will want to get a smaller version. I'd recommend getting a longer usb cable so you can keep your phone or tablet in your backpack or in the shade when charging.

Overall I have no complaints really, works great so far.
