K & F always makes fantastic products and this battery charging combo is no different. The batteries are always quality and recognized by Sony cameras, which seems to be a problem with other batteries they last just as long as the factory batteries, if not a little bit longer overall you can’t beat K & F quality

Work great as a cheaper alternative to the Sony branded batteries! No issues within camera and seem to compare well with Sony batteries in terms of power and life. Charger is a bit slow but other than that, excellent bang for your buck with these alternative branded batteries!

These batteries are a great alternative to the OEM ones. The lower price point is an obvious reason, but so far, these batteries have not triggered any warning codes on my FX30, which makes these a great choice.
I haven't noticed any big performance differences between this and my original Sony ones either. As mentioned before, I don't get any 3rd party battery warning messages popping up during the power-on cycle! And I just updated to the latest firmware on my FX30 too and so far, these batteries are working perfectly!
Overall, this is a fantastic battery set for the money. Charger works great. Everything feels quality and well-made. I also love the set includes a protective cover, one for each battery, which is great for my travels. I highly recommend it.

The K&F Concept NP-FZ100 2600mAh Battery and Charger Set comes with two 2600mAh High Capacity NP-FZ100 Batteries and a Dual-Slot LCD Charger stand. This charger stand does it right. While charging the LCD screen shows an animated battery image filling up and when it is finished it stops the animation just shows a battery image full so you can tell it it is done. Too many other chargers on the market never indicate when the batteries have a full charge. The batteries work great withe my Sony camera too. Recommended!

These batteries charge fast a last a while! I was happy to see that they didnt heat up while charging! I've had a few that has done that. The batteries lasted a long shoot that took 4hours! I was surprised! The batteries are compact and easy to travel with. They are good quality batteries.

Batteries fit both my A7iv and my partners A6700, great battery life, high quality product.
Haven't had a chance to compare with the OEM Sony batteries yet but performance initially seems excellent.

Two good NP-FZ100 USB C batteries that offer a high capacity of 2600mAh, giving you good power and battery life for your Sony devices.
K&F which is beginning to be well known so will be seen over time but it is a good drum kit at the moment.

Perfect kit for me as my FX30 battery could only be charged when the camera was plugged in.
One of my biggest dislikes about my FX30 was that it only came with 1 battery and had no exterior charging block to charge the battery outside of the camera. It is annoying to have to have the camera body be on my desk taking up a decent amount of space just to charge a battery that would normally come with a charging block. This one from K&F comes with 2 larger mAh batteries and an external block I can setup to charge my batteries outside of the cameras body.
The batteries have a slight bit more power storage than my OE Sony provided battery which is great as batteries tend to go through juice quite fast when shooting at higher resolutions. The fact that it also comes with 2 batteries makes sure that I can have extras charged and ready to go as I shoot footage throughout my sessions.
The batteries charge fairly quickly and fit into my FX30 perfectly with no fitment issues. I would highly recommend this battery kit to those that are looking for more batteries or for those who can only charge their batteries through the cameras body.
