I recently purchased the K&F Concept NP-FZ100 Battery and Charger for my Sony A7IV, and I’m thoroughly impressed. The batteries are fully compatible with Sony original batteries, and the dual charger is extremely convenient for keeping my camera ready for long shoots. The build quality feels robust and reliable, and the performance is consistent throughout my use. The only slight downside is that the batteries take quite a while to charge via USB-C, but considering the overall value and reliability, it’s a minor inconvenience. Once charged, the batteries last exceptionally well. Overall, I would highly recommend this product to any Sony A7IV user – it’s cost-effective, well-made, and incredibly useful.

the charger works well and allows me to keep my batteries topped up off camera.

The batteries are great and doesn't give me 3rd party errors on my Sony FX3. Charging unit is also solid and charges my batteries fine. However, the cable it comes with reads as faulty on my phone and states that it has slow charging speeds. Therefore, I have not been using the cable for the charging unit.

Works great just like original and cheaper

Batteries worked fine for the price but after some time the charging contacts developed a fault. The seller kindly offered a replacement, so very good response and service.

This battery is very good, works well and last just as good an my Sony branded ones, the best part about buying from k and f is their customer service even for items bought on amazon. I had an issue with one of my battery that it stopped working and they sent me a brand new pack with 2 new batteries and charger all for free, i cant thank them enough ❤️

The batteries couldn’t hold a charge to power the camera, even after being fully charged. This happened after just two weeks of use.

Great batteries fast charge hald the charge too build quality is great compact no fuss no muss light but not too light

I recently purchased the K&F Concept NP-FZ100 Battery and Dual Slot Charger Set for my Sony A9, and I couldn’t be more satisfied with my decision. As a photographer who often shoots for extended periods, having reliable and long-lasting batteries is crucial. This set delivers on all fronts including traveling. Battery Performance: The 2280mAH capacity ensures that I have ample power to last through long shoots without constantly worrying about running out of juice. I’ve found these batteries to be just as reliable as the original Sony ones, if not better. They hold a charge well and provide consistent power output all while charging fast Dual Slot Charger: The dual slot charger is a game-changer. Being able to charge two batteries simultaneously saves a lot of time and hassle, especially when preparing for a big shoot. The charger is compact, easy to use, and the LED indicators clearly show the charging status of each battery. Value for Money: Considering the quality and performance, this set offers excellent value for money. It’s a cost-effective alternative to the original Sony batteries and charger, without compromising on quality.

Most of the cost is from the batteries themselves. The charger is ok quality. It doesn't charge that fast to be honest, will take a couple hours to charge 2 of them at the same time to full. For the price it is very good, hopefully the batteries will last a long time!

So I got these K&F NP-FZ100 batteries and the charger for my Sony FX30. Been knowing about K&F for a bit, they're pretty popular, but this was my first time trying their batteries. First off, the batteries are solid. They last pretty long, which is dope when you're out shooting for the day. Don't gotta stress about running out of juice mid-shoot. And they fit my FX30 perfect, like they're made for it. They're new obviously but right now they feel pretty comparable to the genuine sony batteries. The charger's great too. It's got room for charging two batteries at once, which is super handy. Charges up faster than I thought it would, so that's a big plus. I can juice up both batteries and be ready to roll in no time. What I really like is the value. You get two batteries and a charger for a decent price, way less than what you'd pay for other brands. And the quality is up there, doesn't feel cheap or anything, seems to last quite long. All in all, if you're shooting with a Sony FX30 and need extra batteries, this K&F set is a great choice. Good battery life, fast charger, and won't break the bank. Totally recommend it!

The batteries and the charger work great and the batteries will not damage your camera. Price is perfect and they work great with my SonyAlpha7r5.

Doesnt last as long as sony but its good for the price
