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.

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.

You do now get a warning on a7iv that they are not recognised. But work ok.

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

Works great just like original and cheaper

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

It's K&F, perfect, enough said delivered in 2 days

No indication of what the coloured LEDs mean and they do not change colour or flash when the batteries reach 100%, so you have to put them in the camera to see if the are 100% charged.

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!

Fits the Sony batteries perfectly. Lightweight. Worked great for a couple months, but now one of the slots does not light up and will not charge. Contacted customer service and they promptly replaced the entire set. New charger works great. All batteries work well with my Sony a7IV--no issues. Great price for backup or replacement.

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