Using my NEX camera body with original charger and cable.
Not useful at all, as I can only charge while battery is in the camera.
Needed a way to charge batteries externally.

Picked out the 2 pack version.
This includes: 2 1100mAh rechargeable batteries, 2 charging cables, 2 instruction sheets.
Charging cables are 24" from end to end, with a built in hoop and loop strap.
USB-C at the camera end and USB-A at the charging end.
The batteries are white on the front and sides.
USB-C port is on the front along with the built in charging LED.
Back is gray and has the information label.

Charging.
Connect with the provided charging cable.
Plug into the battery charging port.
This port can only be accessed out of the camera.
Power bank was my preferred way to charge the batteries.
LED color is red while charging. Green when fully charged.
Side note.
The batteries will also charge inside the camera using the OEM NEX charger.

Overall.
High quality replacement NP FW50 batteries.
Batteries are easy to find as they are white and gray in color.
Include USB-C to A charging cable with built in hoop and loop strap.
Nice long run times while using in the camera.
Very low drainage while sitting in camera for long periods of time.
I prefer these over the OEM and I can charge outside of the camera.
Hope this was helpful.

Got this to use in the Sony A7RII. Have a lot of spare batteries but the pain was to use a 2 battery at a time charger and take turns in getting them all charged. But with this self charging batteries, can simultaneously charge them all just have to find usb power bricks that’s plenty lying around. Or was thinking about using a powered usb hub. Brilliant.

The battery is well packaged and comes with usb-a to c charging cable. USB-C at the battery end. The original Sony NP-FW50 is 1020mAh but these are 1100mAh so that’s a bonus and would last a few minutes more.

Given these are less expensive than the original batteries they are a great value considering you don’t have to invest in separate chargers. Use the power bricks lying around or a powered usb hub that can deliver enough power. Yeah baby.

The direct USB charge function is great when out and about

I absolutely love this new USB-C direct charging method for batteries. Yes, you will use more charging ports or outlets but this method allows me to charge my batteries via a battery pack.

I have always liked K&F Concepts products and have purchased my fair share of filters but this is my first battery order. Needless to say, these are a perfect fit for the Fujifilm X-T5 and report the same data that the factory batteries show.

Charging is on par with factory batteries when charged in the camera or in a 110v charger. As for charging them via USB-C, your charge time will vary based on the output of the wall wort or outlet you are using. They will take longer than in the camera or in a 110v charger, but the ability to charge on the go is what makes this concept work so well.

They came two in the package and each battery had it's own usb-c cable but there is no wall plus included... you will need to provide your own. Not an issue for me as I have a 110v charger and prefer the usb-c to battery bank method.

Overall, I really like these batteries and hope to see other models of cameras start to come from the factory with this style of charging. It's nice to have options to charge.

Très satisfait. Recharge facile avec seulement un câble usb.

Utilisé dans mon FUJIFILM XT-5 sans problème rechargé quelques fois et toujours OK.
Pratique en déplacement sans apporter le chargeur.

These may not last as long as one but they didn't cost as much as well I also like the fact these can be charged in the standard way and with usbc as well

Worth the money.

Bought these to use on an extended trip. Really liked the USBC port and indicator light on the battery for easy charging outside the camera without needing a charger base. Over four months only had to change the battery once while in the field after some heavy usage. Otherwise, each evening I would replace the day's battery with one freshly charged the night before. As to longevity, I won't know for quite a while but so far so good.

Great replacement for the original. This battery does not require a charger, it has its own usb port. Less items to carry. Very convenient.
Battery life is great. Can’t beat the price.
