Great option. Works well and charges original Sony battery too.

Good product and easy to recharge batteries

​"Este kit de K&F Concept es una compra muy recomendable como alternativa a las baterías originales. La batería funciona sin problemas en mi cámara Sony y el cargador doble con entrada USB-C es extremadamente práctico y rápido, especialmente para viajes. Ofrecen una gran relación calidad-precio."

The charger works great for my original Sony batteries. The batteries don't seem to last as long as the Sony's but they are a good back up for my a7rii.

Great batteries and charger for my sony zve10. No difference in battery compared to the stock sony battery, and the charger can charge 2 at once which is great. Not much to say, they're effective, not expensive, and work well.

It’s a good product for my camera

Batteries don’t last long in a Sony nex-3c camera. Cannot really used them. Need two batteries to last a whole hour. Original batteries would last around 400 photos these one maybe 100 photos per battery. Really bad.

The batteries are great, I use them in my a6400 and they have quite a bit of life in them. Nice substitute until I get my V Mount battery. But until, then recommend this brand 100%

Prompt delivery. Working as expected.

Small and lightweight, this unit charges quickly. The batteries don’t get hot during charging. Charges via USB-A or USB-C, very handy. Recommend.

I need replacement batteries for the Sony ZV E10 and I needed an external charger for these batteries. This product is a charger and two battery. I have used the batteries and the charger regularly for months. Everything is working well. The charger charges up from 0 to 100% quite quickly. I can't recall for sure, but if memory serves, it is less than one hour, which is fine for me. Also, the replacement batteries seem no different, in terms of time to drain or time to charge, from the Sony brand battery that came with the camera. I have only had the batteries and charger for a few months, so who knows what it will be like in a few years. It could be that everything continues to work as well as now, or things could start deteriorating. Time will tell, but at least on the basis of a few months of regular use, it is very satisfactory.

battery drains fast.

Good batteries for the price, type c port for charging is a great benefit. Also had an issue with the charger where pins in one of the slots sunk and it didn't work. Reached out to the customer support and they sent out a replacement.
