Works great, Sony should include one as standard but it would have to be as good as this one! Charges much faster than charging in camera and charges two batteries at once. Worth the money IMHO!

Good charger and batteries. Bettery life is as good as my more expensive sony ones.

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

Super happy with this charger! Very compact, easily fits in my camera bag and you wont even notice the weight! Battery life is really good, managed to get through a full day of on/off shooting, took about 400 photos with my A7iv and it only used about 30% battery Would highly reccomended!

I’ve been using it for a while. I’ve had no problem. The charger also good for original battery

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

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.

Works great just like original and cheaper

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!

Perfect aftermarket accessory at a fraction of the price! Works just as well as Sony OEM batteries and have the same capacity. They charge super fast on the included charger. The charger is versatile and will also charge the Sony OEM battery (as expected). Excellent quality at a fraction of the price. What's not to love?

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

Good

I just went out to use the camera for on the trail. I had the other batteries ready just in case. I am still on that same battery. Though it went down pretty fast originally, it has held for at least three hours. If you looking for some good batteries for a good cost, would definitely recommend. They aren’t as long as the Sony batteries but you get your moneys worth. Charge speed is good and the Functionality is okay to me.
