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.

Great battery replacements for my Sony A7iv. They hold a good charge and the charger can even charge the original battery. Works as needed.

I’ve been using the K&F NP-FZ100 2280mAh battery and dual slot charger for a few weeks now, and I’m thoroughly impressed. The batteries hold a charge exceptionally well and perform on par with the original Sony batteries in my camera. I’ve used them for extended shoots and haven’t noticed any overheating or performance issues. The dual slot charger is compact and efficient—perfect for travel. It charges both batteries simultaneously and includes a USB-C port. The build quality feels solid, and the LED indicators are clear and helpful. Overall, this is a fantastic value for the price. If you're looking for a reliable backup or replacement battery system for your Sony camera, I highly recommend this set.

Two nice batteries and a charger that can be connected to a USB port. Perfect for traveling and saving time while charging.

The charger is fine and works with the OEM battery. The batteries work fine in my a6700, but they go down to 80% rapidly. I don't think one of these would last a full day for travel shooting. Given the high cost of OEM batteries, this is a fair deal for the convenient charger and a couple of backup batteries.

Great value good product lots of battery life

Update: 8/19/2025- I was contacted via email from the provider of the batteries and charger. They sent me a new set of batteries and charger. I just received them this past weekend. I charged them and they fully charged. Thank you for sending me batteries and a charger that work. Original review:Update, iv had this charger for almost a year and never had to really charge these batteries. Just went to go put them on the charger and they blink red at all times and never charge. Not sure what went wrong.

I have been utilizing these batteries for approximately ten months, and their performance has consistently matched that of original equipment manufacturer (OEM) products. I highly recommend them for recreational video recording. Camera used sony a6700.

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!

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.

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!

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

Good
