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.

One of the problems of being a photographer is the cost associated with most gear. I already sink tons of money into lenses and bodies, so I really would like to get a break on the other stuff where I can. I opted to get these batteries instead of the Sony version because the price was MUCH lower. They came charged to about 60-70%, and I popped them in the charger to get them to 100%. As normal, my A7R5 pops up a warning that 'this isn't a recognized battery', but they work great anyway. The A7R5 is a battery hog as it is, so I needed to have at least 4 extra batteries for Weddings and long sessions. These work great, and for the price, I can get more sets and have 8-10 spare batteries with me on any shoot. Doesn't seem to make sense to me to buy the official name brand batteries. One thing I did note, when you plug an official Sony battery into this charger, the charger indicator doesn't function. But if you leave it in there for a while, I do overnight, it's always 100% the next day. So, value for money, these are great.

I was sceptical at first, but in a last minute pinch before heading on a trip to Japan I purchased this battery set and was not disappointed. Throughout my trip they worked great, charged as expected and lasted about as long as my Sony battery as far as I could tell. Two weeks in Japan so two weeks of use not one problem or hiccup. Great value for the price.

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.

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!

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.
