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.

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

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.

I was in desperate need of getting new batteries for my Sony camera and they turned out to be the best option to go for. Knowing the brand and its accountability and its affordable price, I just assumed the product would meet my needs just fine. So it did. The batteries work as they were the Sony original ones. And the charger station makes charging so easy, allowing two of them to get their energy back at the same time and being compatible with the original one from my camera as well.

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

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

These batteries are not efficient. I have 2 genuine Sony batteries and decided I wanted a couple extra as I had a full day of video shooting. The two of these K&F batteries depleted at the same time it took for 1 of the Sony batteries to deplete. Capacity might be the same, but the efficiency of the OEM is miles better!

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 ❤️
