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.

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!

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.

Very cheap qulity item

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.

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.

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?

I hate that Sony sells the fz100’s for $120, these however work perfectly no difference at all! And you get two plus a battery station it’s completely worth it and they last longer than my Sony one did! I have nothing but positive things to say about k&f concept!

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!

This battery and charger combo is essential for anyone shooting heavily on Sony bodies. The dual charger is compact, charges via USB-C quickly, and the status screen makes it easy to monitor progress. The batteries hold a charge remarkably well, matching the longevity of OEM power without any compatibility errors.

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