The dual charger is a good addition to my Sony A55 camera. The battery performance has been satisfactory so far. However, like the originals, they also discharge after a while in the camera. This may be model-specific. The charger can be used with both USB-C and Micro-USB. The charging time depends on the adapter used. I'm very satisfied with the set.

The NP-FW50 replacement batteries from KF Concept, including a dual charger, are of high quality and visually appealing. They fit perfectly in the Sony A7II and provide reliable power. Their battery life is just as long as the original batteries. Charging is fast, and thanks to the dual charger, two batteries can be charged simultaneously. The charger is powered by the included micro-USB cable. Alternatively, a USB-C cable can also be used. A great idea if you don't have the right cable with you! I can't find any complaints here. A great set for a fair price! I'd definitely buy it again!

This is a pretty decent set and a good price. Compared to the OEM, the batteries retain their charge well and charge quickly.
There is not a lot else to say about this set other than it is a good product at a good price if you need additional or replacement batteries or a charger.

I got this and a battery grip for my Sony a6000. Went on vacation and only shot photos and the batters lasted all day. It was 90 degrees outside and no issues.

Works amazing. Fits my Sony A7iii with no issues. They work just like the original Sony batteries. Love these and love that they come with their own charging station. I highly recommend these to anyone.

Anyone who uses the NP-FW50 batteries knows you can never have too many of these! The sony ones are expensive. K&F is a great brand who makes most of my camera filters, and some other things so I trust that these will last just as long as the originals. So far they are performing like OEM and the charger is nice to be able to charge a couple at a time. Can't go wrong here...

These batteries do a good job of powering my Nikon, they're easy to keep charged, with the included charger. They're priced fairly for lithium ion batteries. I'm glad I ordered them. If I run into any issues with them, I'll update the review.

This works perfect with my Sony A6100. They fit just the the O.E battery that came with my camera. Charge bay's are nice because you can charge two battery's at the same time. One thing that I have noticed with other brands is that on a full charge according to the base, they are not fully charged on the camera meter. But with this set by K&F when the charging bay show done and the battery is inserted into the camera it does actually read 100%. Battery life is about the same compared to the O.E battery. The only complaint I really have is that is comes with a micro usb cable. The reasoning behind that is that most of my equipment runs usb type c. But on a plus note there is an option on the charging bay to use that cable also. it just not provided other than that This is a great buy!

The A6500 batteries don't last a super long time because of their size so it's always great to have extras. I have a number of filters from K&F Concept and they are high quality. These batteries and charger reflect the same level of quality. Very nice. They also come in a very nice box so are gift-able too.
