Great batteries. Last just as long as the OEM Sony ones. Great charger too. Charges batteries to capacity in about an hour and even charges the OEM battery

This K&F Concept battery and charger set is a great addition to my camera gear. The batteries work seamlessly with my Sony ZV-E10 and A7II, providing a reliable power source for long shoots. The charger is compact and charges quickly, making it perfect for travel or on-the-go use.Having extra batteries is a lifesaver, especially during extended sessions, and these perform just as well as the originals. A solid, affordable option for anyone looking to expand their camera kit without compromising quality.

Compared to the official market offers this is a steal of a kit for the price, double charger and 2 extra batteries? Batteries work and are compatible with SONY and others. However i notice that the connection pins are much more prone to bending or breaking, as well as not holding a charge for as long as official parts. Nontheless it may be worth getting because youll get maybe an extra 1- 1.5 hours per battery. Can come in very handy in desperate times.

The K&F Concept NP-FW50 Battery Charger Set is a lifesaver for my Sony ZV-E10 and other Alpha series cameras. The dual-slot charger ensures I always have a fully charged spare, ready for action. Its compact design and compatibility with various Sony models make it a must-have for hassle-free photography sessions. Highly recommend this reliable power solution!

The green lights are always on which should indicate charged. But they are not and never have been charged. I wasted time troubleshooting my camera thinking I had fresh batteries inside and it wasn't working. Do t waste your money.

Charged v fast. Small, neat and tidy pack. Comes with usb-c to usb charger which is silly nowadays but there’s plenty of usb-c to usb-c cables lying around.

The K&F Concept NP-FW50 Battery and Charger Set for my Sony ZV-E10 has been fantastic! The batteries hold a good charge, comparable to the original Sony ones, and the dual charger is super convenient, allowing me to charge both batteries at once. This set has really improved my workflow during long shoots, and the charging times are quick. Overall, it's a great value and reliable alternative to more expensive options. Highly recommend for ZV-E10 users!

I have needed to get a new battery for my venerable Sony A7RII for a while. At this price point I figured it made perfect sense to go ahead and get 2 batteries and a charger. I have never used K&N equipment before, but so far it looks like a good choice.After charging the batteries I went out over a couple of days to shoot a Cross Country running event. I did some light still shooting for a couple of hours each morning using 1 battery each morning to make sure they both worked. Both had charge left after their respective morning shoots.The charger is very lightweight and has both a USB-C and Micro USB slot. Typically I like wall chargers, but when I travel I like this type of charger. The reason being often times in older parts of the world, basically anywhere but the US, where electricity was retrofit into structures the power plugs are in odd spots and a cable makes it easier to plug into the my power adapter and sit the charger somewhere convenient. The fact it has the C and Micro slot is nice in case my cord and backup cord dies and I have to get a replacement.Time will tell as far as longevity, but so far this has been a great purchase.

Big plus: accepts both micro-USB (which came with my Sony camera) and USB-C (so can use same charge cord as my phone). A minus is the charge indicators are red for less than full charge or green for full charge - there is no progress indicator. Also no directions are included but in reality none are needed.

The batteries fit and perform just like my original Sony battery. I don't see a noticeable difference in performance (either way, longer or shorter) which is fine. I like that the charger will accept power from Micro-USB like the camera or USB-C like almost everything else I own, so the chances that I have the correct cable are effectively doubled.Later on down the road there may be some effects of different cells in the battery pack - and I'll try to remember to update this review if anything abnormal happens. But while they are fresh and don't have many cycles on them they are every bit as effective for me. Given the price difference and performance so far, I would buy the K&F Concept batteries 10 times out of 10 over another OEM battery the next time I need a replacement. The dual-power charger is a bonus.
