K&F CONCEPT 2-Pack NP-FZ100 Battery, USB-C Fast Charging A7iii Batteries Compatible with Sony A7iii A7iv A6600 A6700 ZV-E1 FX3 FX30 A7Riii A7RIV A9 A1 Cameras

Works well. Provides credible Reharges quickly. Recharges quickly with PD charger. Since Sony does not provide a charging adaptor, these batteries become a very real alternative.

I'm using these with the Sony a6700, but these are compatible with other Sony models. I have had no issue with the camera display saying there's anything wrong with these batteries. The batteries have a USB-C port for charging. I have found that they last a bit shorter than the OEM Sony battery, but just a bit. Good value for the price.

These work perfectly. I got a portable charger to keep these in my bag. I dont shoot videos so I dont need that continuous charge and extra weight on my rig. So these are great

I’m using this battery in my Sony FX30. I am not a fan of Sony batteries as they tend to discharge too quickly. This was my experience with the A7r battery shooting video. The FX30 can be powered by a power delivery system using USB-C. However, my v-mount battery system only supports d-tap with the dreaded dummy battery. So I decided to try these batteries. The good news is the batteries work great. The less than good news is that with the last firmware update from Sony , you get a message saying the battery can’t be guaranteed to run the camera. However, I have not experienced any issues. I just finished shooting an hour and a half video and easily got over an hour on the first battery.

fantastic alternative to the stock Sony as it has a usbc charge port so you can charge it easy, no need to carry a charger for a battery, just your normal phone charger!!!! Charge lasts slightly less than Sony

I have so many of these, I lost track. 10/10 Extremely good to have it’s own charging port too. I can charge multiple battery at once. Although the fx2 did give me a notification about third party batteries. The battery life is good, if not better that the original, easy to use, basically point and push.

Who would have thought by nixing the charger, via a simple usb-c cable would be so liberating, but here we are! I love these things so much, I honestly believe that more manufacturers should look into doing more rechargeable batteries like this. The charge is excellent and comparable to the OEM Sony batteries but these really offer so much more flexibility in getting them charged! Love them!

I tested with a Sony Alpha IV without a problem i read that some batteries cant show battery indicator but with this i dont have that problem

Bought as spares for my a7riii and they work great giving decent life, very easy to charge either with type c connections built in so can be charged in the car on the way to the next location if needs be. Decent price too.

Je ne vois pas trop de différences avec la batterie originale pour le moment. Bon rapport qualité prix. La recharge via USB-C est un véritable plus.

I used this on my backpacking trip and the performance is phenomenal! Not only it has USB C charging, it also charges faster than the original batteries. Considering I'm in an environment without electricity, my power bank was enough to charge them a couple of times. If it's the original batteries, for some reason, it drains my power bank more. Also, people told me that the Sony system doesn't allow other factory's batteries anymore but my camera uses it like its own, no problem at all. I don't know about the lifespan of this battery yet because it has only been a few months, but so far it outruns the original batteries!!

So I bought this for the a6700 and when filming and taking photos, each battery lasts around an hour. Very disappointing and expected more out of them but I would not recommend if you were to use these for shooting more than 2 hrs

Preisleistung ist wirklich top. Die Akkus lassen sich prima über USB C laden. Ich nutze die Akkus in einer A7S3 und in einer A73. Die Akkulaufzeit ist in Ordnung. Klare Kaufempfehlung.
