slightly fast running out..
The reason why I gave 4 stars to this item is that this one is running out slightly faster than the original Sony battery. As it said, this one has more capacity than the original one, so that I believed this one lasts longer than the original one. However, it is quite distinct that the voltage drops faster than the original. I'm using A7. After fully charging it (100%), you can easily see that about 4-5% of the battery power is gone with just a few shots, when you're using the live view in the back of the camera.

Very tiny, but super powerful.
This module doesn't have any capacitor on it, but most of the USB power sources don't provide high current output, so that you may need a large capacitor for it. Otherwise we'll hear a loud popping sound whenever your amplifier needs large current flow. In case where you have a high current USB power source, this amplifier fully rings your stereo loud speakers. Surprisingly, this amplifier drives my 30W guitar cabinet!
