K&F Concept NP-FW50 Battery and Dual Slot Charger for Sony ZV-E10 A6500 A6400 A6300 A6000 A7 A7II A7RII A7SII A7S A7R A7R2 NEX-3 NEX-5 Cameras

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

Purchased this for my sony NEX . The original batteries were not holding charge well. These batteries brought my camera back to life.

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!

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 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.

batteries work good, charger died on me 3 weeks later

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.
