Works in sony A7C and FX3 with no warnings or issues.

I tested this with a USB power meter. I discharged the battery to 0% and then charged it via a fast charge usb brick and the power meter. It charges at a max current of 1.65-1.8amps at 5v. This is a nice and fast charge rate.

Total power used to charge was 3,994mah at 5v which equals 19.97Wh. At 95% charge efficiency that equals a true capacity of about 18.97Wh. The battery is listed as having a 18.72Wh capacity so this is almost exactly spot on. Many other batteries i test have exaggerated capacities but this one is exactly as listed so that is really great.
Can't beat this battery for sony cameras!
Good Battery with accurate Capacity

The benefits of extra batteries is a must, but not at the price original ones cost!, these are the perfect alternatives, not only can they hold their charge longer than most, they are dual charging having the versatility of usb or adapter charging! Very handy, plus the added bonus of not triggering the Sony software for being third party items, definitely recommend, worth the money 100%
Must haves! Must haves!

More capacity, USB-C charging, and NO warnings! A winning trifecta in my book. Other brands make claims but K&F has done it. On top of all this they don't break the bank either. I'm glad i found these as i will definitively get a few more.

Works perfectly in my a6700
They WORK.. NO WARNINGS!!!

This is a set of two and works perfect in my A9
I have a battery grip and this is my backup.
I did not have extra batteries and these two takes that job. I am very excited.
Fantastic.

I'm surprised how long they last, noticeable longer than other brands and a bit longer than original Sony, works with FW 3.01 on a74 without any issue...so kudos to them.

Edit. 12.12.2024 Installed FW 4.00 on Sony a7IV and they still works without any issue

The built quality is excellent. It works just like the original Sony battery, and I haven't noticed any difference in charge. The main reason I got this battery was because of the fast USB-C charging, which is excellent. I can fast charge the battery in my car. Excellent value for the money.

I cannot vouch for the capacity. I doubt it, but not because of evidence. Because it has to make room for a USB port so I find it hard to believe that there's more juice capacity than they stock battery that doesn't have a charging port.

That said, charging port means it charges faster than if I have to charge through my camera. It works and is read by both my a6700 and FX30. Very happy with this set of backup power.

Great for my Sony FX30 and the fact that I'm getting two quality batteries at this price is amazing. So far I've had no weird hiccups or issues. No overheating or burning smells. Turning the camera on and off doesn't come with any glitches and navigating the menu is simple. These may sound off, but when you use different batteries that aren't from the manufacturer, sometimes you can get some unsettling results through regular use - like at one point my Wasabi batteries overheating my Pocket 6K. So it's important to look for any operation anomalies as you use different batteries. These are great and I definitely recommend.

as good, or better than OEM considering how versatile they are- - the fact that you can plug USB C straight into the battery is a game changer. especially since they provide identical battery capacity to stock batteries. i cannot recommend these highly enough.

At the end of the day, they’re batteries. They work to power my A7S III. I’m fond of the USB-C port because the last thing I want to bring with me when travelling is a separate battery charger.
