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, Better than expected when I got them. Charges every where on the go and great price.

This was a great battery replacement for my Sony ZVE-10 Mark 1. The packaging was nice and the indicator lights really helped with telling if the batteries were fully charges are not. Something like this is a must for heavy camera users and the battery life on the Sony ZVE-10 can be a little lacking when using it for Vlogging. I would definitely buy it again if it ever fails but, I don't see that in the foresee able future knowing K&F is a great brand.

Easy to use. Charges quick.

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.

Always have extra batteries you will need them..

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."

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.

battery drains fast.

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.

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.
