I love the new USB-C port that companies are putting on NP-FZ100 batteries. It makes it so much easier to charge up in the field with a larger battery pack, so I can alternate between two NP-FZ100s with a battery pack and be ready to go all day, rather than having pockets for charged and then discharged batteries.
Plus, I can forgo a specialized charger if I'm on a trip and want to just bring one big USB charger for all my electronics.
I just reviewed a non-name-brand 2-pack of these batteries, and they were too big for the camera's battery slot (even before any chance to heat up from use). That's scary, since it could ruin the camera trying to pry one of them out.
I didn't have that problem with this one, or with another popular trusted brand's version. They've worked fine in the field. I've been happy with products from K&F Concept, so I'm fairly confident recommending this one.

These are a decent bunch of batteries from K&F Concept. The USB Type C charging port is a feature I welcome very much.
It has similar battery life to the OEM Sony NP-FZ100 batteries. I definitely think this is a great hit for anyone that's looking for batteries on a budget but still wants to power up their camera with confidence. I'll be using this for work, and I think it's still a great option for that.

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

I’ve been using this battery for about two weeks in a Sony A6600. The original battery, NP-FZ100, is long lasting. I shot 50 photos with this battery at full charge with minimal discharge of less than 99%, which is normal with the original battery. After a week of non-use the K & F Concept battery was still at 99%, which is very good. Both batteries have the same 2,280 mAh. I’m giving 5 stars as the battery performs. The only advantage I see is the battery can charge without a charger outside of the camera. As it’s possible to charge any NP-FZ100 battery in camera. If you do need to change this battery on the go you only need a USB-C cable and a charger or car adapter to charge this battery. One less item to pack in the bag!

I tend to keep a lot of extra NP-FZ100 batteries on hand for long back-to-back shoots and this is a great replacement battery/battery to add to your collection. Functions as well as an OEM Sony battery with the benefit of being able to charge them while you're on the go without needing to bring a specific NP-FZ100 battery charger (e.g., via USB-C in the car, at your hotel, etc.). Currently use this as my primary battery/always leave it in my backpack in case my batteries die on me so I can at least charge up one battery while I'm away from my charging station in my office.

Great for Sony A7iV. Batteries are as good as official Sony ones, if not better, and much batter value and price.
Fits perfectly like OEM batteries and lasts ages. And great having two in a pack for a quick swap!
Haven’t had any compatibility issues nor had my camera errored about having a different manufacturer battery as some people have said.

I like these batteries better than the one that come with my r7 due to the fact you can charge them over USB C which is a bit of a game changer. I havent had any issues with compatability however I feel like these are getting more and more expensive

Function exactly like the original Canon LP-E6NH. Charge relatively quickly, USB-C so convenient. Hold charge well (obviously for a new battery) but also no issues with voltage. Seemingly high quality and show all stats in the camera like exact battery percentage and charge performance. Very happy.

Charge up well as last a fair time when in use in camera. Bought as back ups to carry around.

Purchased as back up batteries for my Canon R6 MkII , I find them excellent in everyway . Comparable charging times and they appear to remain charged just as long as my originals . The really nice touch with these batteries is you can charge them directly using a USB cable .. Plug straight into the battery. Admittedly charging this way does appear to take a little longer than using a mains charger but nothing I cant live with . Overall great product , great value for money .
