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.
La batterie de ma camra est une vritable trouvaille ! Elle offre une excellente autonomie et une qualit de fabrication solide, tout en tant incroyablement abordable. J’ai t agrablement surpris par sa performance, et elle s’est avre tre un excellent investissement pour prolonger mes sessions de tournage sans me ruiner. Je la recommande vivement tous ceux qui recherchent une batterie de qualit un prix abordable.
These are just as good as my original Sony battery. There is no noticeable difference in how long the charge lasts. I think 2 batteries with a dual charger at under $30 is a fantastic deal. The battery charger charges the batteries fast and lights up green when the batteries are full. And having USB-C and Micro-USB is a big plus as you may need one or the other for another task at the same time. I think this charger was well thought out by K&F Concept.
I got this for the charger as Sony batteries don’t last long in their mirrorless cameras. I finally. got a chance to really test the charger, which means, charging eight Sony and third party batteries several times. That includes the batteries that came with the charger.
The charger holds the batteries securely, better than the Sony OEM charger. It stops charging each slot independently. It appears to charge in about the same time as the Sony charger.
This charger plugs into a USB -A type port. Whether that is good for you or not is a personal preference. As I can plug two (or more) of these chargers into a corded USB to 120v adapter rather than have the Sony OEM charger take up a plug or the entire outlet as it covers up the outlet, I like it.
I haven’t used the batteries enough to really tell how they rate against other third party batteries, but against real Sony batteries, even all mine, which are several years old, they don’t stack up. I estimate about 50-60% of OEM charging life (or endurance). But I really need to see how they do over a year.
One thing, static drain over a few weeks is far better than any other aftermarket Sony compatible battery, including a different one I bought around the same time. After four weeks sitting on the shelf, the K&F batteries didn’t loose any charge. After a week without use in my A7R2, one still showed 100%. That is better than most, even if the endurance is less.
So if you get this charger with two batteries for $30 or less and figure the charger is worth $17-20, I’d call it a good deal
Great little budget battery and charger set. Charges batteries fast, works with both official and other branded batteries. Included batteries hold charge well and don’t preform noticeably deferent from my official Sony batteries (although I haven’t really pushed them super hard). The whole bit of kit is super easy to just throw in the pocket of my camera bag.
I snagged these for use with my ZV-E10. I generally only record @4k60, and dont do much still photography
Good:
Battery Performance seems to in spec with OEM batteries
Charger is great. decent charging speed / dual charging inputs (C & micro usb)
Batteries fit tightly like they should, and don’t fall out if accidentally tipped over
Bad
Stop using micro USB period, let it die like it should have long ago.
Overall, this is another win for K&F, especially since i have another brands FW50 battery also, that has higher capacity, but will not last anywhere near the time of even a OEM battery.
