Game-changer for my Sony camera! This NP-FZ100 battery charges in a flash with the Type C port.

I love that I can use these in my Sony FX30 with no annoying battery error. PLUS when you need to swap one they have an awesome USB C port on them to fast charge.

Excellent value for money, they have the nice touch of being able to charge it directly without the need for an adapter or putting it in the camera, the original Sony ones could have that functionality.

Not too much to say apart from these are great batteries for the price. I can barely notice any difference in battery life when compared to the one that came with my Sony A7iv. Great quality and seem durable. The USB-C port built into the battery is game changing. I would highly recommend.

This K&F battery works perfectly with my ZV-E1, and does not trigger the non-OEM battery warning. I've had it for about 16 months and it still holds a charge well. I've always been skeptical of the 2,280mAh claim, since it houses a USB-C plug and no doubt some additional circuitry than the same-size, same capacity Sony battery, but it does not discharge at a rate alarmingly different that the OEM. Being able to charge it with only a USB-C cable was the main draw for me, so I'm glad that works reliably; this has made an excellent back up.

This may not hold up as well as a dedicated charger - time will tell, but so far it's another affordable and well functioning product from K&F - no battery warning in my A7r IV. Battery life at full matches with mAh indicated. So far I'm impressed.

Love this USB-C rechargeable Sony NP-FZ100 battery. This thing will help with the gear you have to take on location with you. Also eliminates option of carrying battery charger with you. Also, it charges pretty quick.
Pros
Easy to use
Eliminate need to carry separate charger with you
Charges pretty fast
Cons
None

Package comes with Battery, Battery protector, and USB-C Cable. I love the fact that I could charge this battery without bringing a dedicated charger so I can cut down on how many items I need while traveling. The battery has an indicator led on it to show when it is charging (red) and when it is charged (green). Some aftermarket batteries give various issues such as showing up as under charged (ex. 95%) or the camera will complain about the battery. I haven't had any issues and the battery seems to last just as long as the original sony batteries. And, you can purchase two of these batteries for the price of a single Sony battery. Great deal and I'll be recommending these going forward as well as picking up an extra.

Bought these batteries for the sony a7iv and fx 30 that after the latest updates give problems with non-original batteries (you don't see the percentage of charge and the battery is not compatible warning)
With this everything is ok, percentage of charge ok and no warning. .
To be tested in the field to see the actual duration.
