Extremely slow

It took about 4 and a half hours to charge two Watson batteries that were near empty. If you have that much time to allow this, it gets the job done.

Well-made and Well-designed.

I love this charger. I don't know about you, but I have a lot of batteries that I use for my cameras, especially these NP-FW50 which work with my Sony RX-10 Mark 4 and Sony EV-Z10. Having a dual charger that charges 2 batteries at the same time is such a time and space saver. The charger contains 2 easy to read, individual led displays that lets you see the status of each port/battery, which is very helpful. This way you can see the status of each individual battery very quickly. I love having led displays, and theses displays show clear intervals which is more than enough to keep you informed. The design is also very good. Even though it can charge 2 batteries at one time, it is still very compact and lightweight, so it does not need much counter space. I love that. It is made of plastic which keeps it very lightweight and great for travel. But it is a very strong and sturdy plastic, so it should last a long time. This charger comes with a USB-C to USB-A cable and the charger/brick, so everything you need is included. Having it work with a USB cable also allows you to not only plug into a wall, but you can also use a power bank to charge if you'd like. That makes it very versatile. The USB-C port also seems well-made with a good fit that is not too tight, but also not too loose. The USB-C cable fits snug and secure.  I love that it charges intelligently, and automatically avoids overvoltage issues and includes overheating protection. This puts my mind at ease. Again, this is a great dual charger and because I use so many of these NP-FW50 batteries, it is very helpful addition to my workflow. [I have received this product in exchange for my honest review]
