I am writing after several uses and I am really very satisfied with these batteries. In my Sony a7IV the usual warning about compatibility that is shown with non-original batteries does NOT appear anymore! And, although not essential, it is nice to be able to charge the battery directly by connecting it to a USB-C cable without using a charger.

I am very satisfied with the battery. As efficient as the original batteries (4 for the price of one) I am waiting to see how long it will last.

Pricey, but you no longer need to carry around a micro usb cable to charge your camera.
Also, it appears to allow charging and usage at the same time (just pop open the battery cover) which allows the camera to run off of AC power continuously. Neat!

I love that when i travel with this battery I just need to have a usb c charger ready to recharge my battery. Before Brining the sony battery charger was the most efficient way to charge the batteries fast but with this battery I can now dependably charge a battery quickly without the need of the bulky charger. Also I like how this is colored differently so I can quickly discern it from others. Love love this concept of a battery for cameras hopefully they will all be like this.

I have been using the Sony FZ100 batteries for more than 5 years now, but this new battery with USB-C charging built-in makes everything so much easier. Now I don't need to carry any battery chargers with me, all I need is a USB-C cell phone charger or power bank. I can charge this batteries in the car, on the go or in the hotel easily. No special cables needed, just the standard USB-C cables. Very happy with this design.

It's a little too soon to assume things, so I'll be honest.
These batteries seem like a great option for anyone that's wanting to save a few bucks on the Sony NP-FZ100 batteries. 3rd party batteries are known to be less reliable than OEM ones, and over time some batteries swell up and get stuck in the camera body.
After a few weeks of using these, fortunately, this is not the case, so they seem pretty decent for now. There's still the risk however, so I'm not going to get all my hopes up.
I still recommend these batteries. They're cheaper and work well. I haven't had an issue with these in terms of powering my camera.

I have a grievance with modern cameras - their batteries deplete too quickly. I purchased some additional batteries from Sony for my A7R3, but they were costly. I was hesitant to try third-party brands, but I recently came across replacement batteries from some well-known brands. I decided to give them a try.
K&F is a reputable brand in the photography industry. I have previously used their ND filters and tripods, so I was intrigued when I saw the NP-FZ100 battery for my camera. It is almost identical to some of the other third-party NP-FZ100 batteries available online, such as those from Neewer. What I appreciate about them and this particular one from K&F is that you do not require a charging dock. You can simply plug in the USB-C cable directly into the battery. This is particularly convenient when traveling. While I am unsure about the battery life at this point, it appears to be performing almost as well as the original Sony batteries.

Whenever I pick up new batteries, I always look for ones with a built-in charge feature. No special charger, no extra room in the camera bag or luggage for a charger. And no FORGETTING a charger. Even if you somehow forget or lose a USB cord, you can get them anywhere. Yea, I have arrived at a weekend shoot and realized the charger was missing. Lesson learned. Even if you prefer standard chargers or charging in-camera, this battery is an ideal backup. Plus, obviously, it's also an additional camera battery.
