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.

Small and lightweight, this unit charges quickly. The batteries don’t get hot during charging. Charges via USB-A or USB-C, very handy. Recommend.

The charger performed extremely well for 9 months but has unfortunately failed; when I plugged it in the indicator lights flashed alternately red and green and the battery did not charge. Product support however was excellent as I was very quickly offered a replacement. Cannot fault K&F for their customer service, which is excellent.

I need replacement batteries for the Sony ZV E10 and I needed an external charger for these batteries. This product is a charger and two battery. I have used the batteries and the charger regularly for months. Everything is working well. The charger charges up from 0 to 100% quite quickly. I can't recall for sure, but if memory serves, it is less than one hour, which is fine for me. Also, the replacement batteries seem no different, in terms of time to drain or time to charge, from the Sony brand battery that came with the camera. I have only had the batteries and charger for a few months, so who knows what it will be like in a few years. It could be that everything continues to work as well as now, or things could start deteriorating. Time will tell, but at least on the basis of a few months of regular use, it is very satisfactory.

Just like the title says. Charges two batteries at once. Has an easy to read indicator to know when it has charged the battery. Works perfectly with the batteries listed. Only complaint is I wish it was USB C so you don't have to carry as many wires around.

I’m really pleased with this charger. I used it with my powerbank today during a sporting event. It fully charged two canon batteries really quickly. It is a godsend for long day events.

I got this because, for 2 batteries and a charger, it's a heck of a lot cheaper than a Sony battery. But as you'd expect, they're just not as good as a genuine Sony battery: they don't last as long in use, and don't hold a charge for as long when not being used either. On the other hand, it is handy to have a couple of spare batteries in your bag, and the charger works very well, and even charges the Sony battery too (which is good because there was no charger with my a6400, I just had to plug the camera in to charge). The charger unit uses a standard USB-C cable, so it'll always be easy to find a spare one. So even though they aren't as good as Sony batteries, you get a decent deal for maybe half the price

Reliable product from a good brand. Good value, batteries fit designated camera no surprises My go to compatible product company
