This 3-slot charger for NP-FZ100 batteries is very convenient, especially for photographers who are often on the move.
Being able to charge three batteries at the same time is a real time saver.
The included batteries have a capacity of 2280 mAh (Real???? not sure...), but there is still a good autonomy.

If you have any of the Sony camera that take these NP-FZ100 batteries, you'll probably find yourself always wanting for more batteries. Well, how about three? Three that work with the latest a7iv firmware (which is causing some of my batteries to show the 'incompatible' warning). And you get a parallel charger to keep it all topped up with.

The charge dock allows you to utilise USB-C or micro USB. I prefer USB-C but having the choice is nice.

At 2280mAh, these are not the largest capacity batteries - but there are three of them, so you'll still get a good three days of hobby shooting or one day of rampant professional shooting.

Here is a very interesting pack. Consisting of a charger, a USB C charging cable and of course 3. NP fz100 batteries perfectly compatible with my Sony A7 3 for example.
Note that the charger has a usb-c port but also micro USB. For example, to be able to use your old chargers or cable. It also has a screen that allows you to monitor the charge of the batteries. Note that it is a simultaneous charge and not one after the other, which is great for speeding up recharging.
The whole thing is well finished, no problem inserting the battery of my camera. It is perfectly recognized by it. Have it over time over the course of shootings but with three batteries. We really have what it takes to see it coming, great.

Tiene muy buena duración y funciona muy bien con mis cámaras Sony.

Batteries charge up all at the same time and fast. Nice viewable screen. Its great!

For use with the Sony A7R IV camera, I got the K&F Concept 3-pack of NP-FZ100 batteries and the 3-slot charger. These battery kits have proven very useful for me over the past few months, and I am very pleased with their performance and ease of use.

The batteries appear to have good longevity in terms of how long they can discharge before needing replacement and can fire at least several hundred shots per charge, which makes these on par with Sony branded NP-FZ100 batteries in terms of capacity. I particularly appreciate the utility of a simple LED indicator on the charger that informs on the charge status of each battery slot with green meaning fully charged and red meaning charging. The fact that it’s possible to charge 3 batteries at the same time is good because these cameras drain batteries rather quickly.

The physical construction of both the batteries and charger also appears to be well-engineered – there are no cheap plastic components here. The battery tabs, for example, are nicely click-in with the camera without any possibility to wiggle. But it is even better that the kit has a car charging adapter which can be used to charge batteries in my car whenever I do not have access to an electrical outlet.

Overal for the price offered, K&F Concept offers an exceptional value with this battery kit. It is very stable for my daily use of shooting pictures and the 3 slot charger is very useful. That means I never lack power to supply all my electrical appliances within my home. Definitely the best for those who own any sony mirrorless camera.

These batteries work as you would hope them to, just as good as the original manufactured batteries. That is good enough right there, but what sets this apart is the triple charger that displays the level of each battery as they charge. This has made charging so easy for me and I love it.

K&F used to be a budget brand that no one really knew about but now they have really upped their game! I own several of their products. From batteries to tripods and even their various filters. All of them I would consider premium products. The battery charger feels pretty generic like most of them out there. Smallrig, neewer, etc. What makes it different is the 3 charge slots which makes it convenient. I typically carry around 10 batteries with me to film weddings and having a charger that can do this amount of batteries at a time is great! One thing that ticked me off about Sony is they released newer firmware that actually removed the percentage on the batteries if they are not from Sony which left you guessing what percentage they were and you had to rely on only the battery indicator like old school cellphones. So even ones that I bought before that stated they were compatible and gave no errors, unfortunately now do. These batteries however do not give you the warning and retain the percentage for now at least before Sony decides they want to be greedy again. Highly recommend this brand. You won't regret it especially for the price.

Looks like K&F is branching out from just lens filters. Their batteries and charger are just rebrands, but that's not a bad thing.

Fast charging and a great bang for your buck of a kit. If you need food batteries and a way to charge them this is for you!
