This charger and battery set is pretty nice, with fast charging rates, a clear and easy to read charging/battery status display, and two batteries that *do not* cause my camera to give me the "The operation and safety of this battery cannot be guaranteed" warning (unlike some of my other 3rd party batteries). The percentage display also functions correctly (some 3rd party batteries just show bars instead of the battery % remaining).
The charger design is sleek and makes slotting in and removing the batteries easy. I don't know that the separating design of the slots from the power base is very necessary, just adding complexity and cost. If I don't want the charging unit, then I'll take the batteries by themselves instead of using the relatively bulkier charger slot segment to transport them. I guess there might be limited use cases for the separating base, but I'd rather see a simpler design that has less moving parts to potentially break and adds costs.
I don't think that's a big enough deal to warrant the removal of any stars from my rating, as the rest of the package works so well. I'm very pleased with these and would certainly recommend considering this kit if you're in need of more NP-FZ100 batteries that are fully compatible with your camera.

Got this to use as spare batteries for long video gigs (weddings, conferences, etc.). The batteries work without issue for the Sony A7 III mirrorless camera, and the two batteries can be charged in the included dock. There is a small screen to monitor the battery percentage, which is a huge plus. These work just as well as the OEM batteries while still keeping the wallet full. Worth.

Battery kit for SONY cameras.
Consists of two batteries, a charging dock, and a USB cable.
The dock's integrated display allows you to accurately monitor the charge status. The batteries each have a capacity of 2600 mAh and recharge faster than the original (which has a smaller capacity).
I recommend it.

The product arrives in a nice cardboard box containing the two batteries, the charger, a USB-C/USB-C charging cable, and a small user manual.
The charging base is conveniently divided into two pieces that snap together. The upper part, when detached, allows you to carry the batteries around while protecting the contacts and also features side slots for carrying additional SD memory cards. The lower part, when attached to the upper part, allows you to easily check the battery charge level by simply clicking on the manufacturer's logo on the front. When connected to power via the USB-C port, the batteries will charge.
The batteries charge faster than the original ones, despite their larger capacity (2600mAh vs. 2280mAh). While using the batteries, I didn't receive any overheating warnings, even though I tried recording videos at maximum resolution (which is a very energy-hungry operation). In standard mixed photo/video use, the batteries held up well, offering longer battery life and a constant decrease in charge. Typically, low-quality batteries cause fluctuations in the remaining charge level and possibly error messages.
All the materials used are of good quality, and the product is well-designed, both aesthetically and to last.

Nice pack of batteries from K&F!
Nicely packaged, and the batteries work great at a nice price. Battery life has been comparable to OEM, and they feel like they're made with a nice grade of plastic. Fit is very OEM like too.
Charger works great and charges quickly, and is compact enough to put in any camera bag.
I've been taking it everywhere with my A7CII and I can shoot all day with no worries.

K&F has really brought their a-game to photography at some great prices.
These K&F batteries are like giving your Sony camera a second (and third) wind. Snapped right into my A7RV. No fuss, no weird warnings (and I've had my camera warn me about other battery brands but these didn't). They last about as long as the originals (if not a bit longer), and the fast charger? Legit quick. USB-C charging speeds up the whole workflow, and I love that the case doubles as a battery holder, clever little touch.
The LED power readout keeps you from playing the “did I charge this?” game. For the price, it’s a smart pickup if you shoot anything more than casual brunch pics.

This setup has been my daily driver for the past month, and I've had no issues. The batteries, when fully charged, last through an entire shoot. I rarely need to swap them out during a session. Charging them is a breeze - I do it overnight, and they're ready to go the next day when I need them. These batteries are just like any other I've used, and they work flawlessly in all my Sony cameras (A7R5, A6700) with no third-party battery warnings. The entire setup is super compact and fits easily into some of my smallest bags (3L). The batteries sit securely in the charger without falling out. The battery case can be detached from the charger, but I usually don't bother since the whole setup is so compact. Plus, if I need to charge them on the go, I have it with me. This is a fantastic package with reliable batteries. At this price, it's an awesome deal!

They are two NP-FZ100 2600 mAh batteries and an 18W charger that give me peace of mind in my photo sessions because I don't have to worry about running out of charge. I use them with my a6700 camera and they provide me with energy to take long photo sessions and record videos. 100% compatible with my camera. These reflect the charge level on the camera screen since I had others that did not give me that information on the screen and they discharged very quickly. I love their charger that for me fulfills two functions: it charges the batteries and they are the case for them to keep them both in one place.

Just outstanding items. Great charger and easy to travel and great batteries that don't show error on my camera. Over time I learned to love and trust this company.
