Delivered within two days, I'm really impressed with the quality of the product given the low price. The charger can be equipped with different battery adapters and the fact that even a car charger is about to make things really convenient. Whether you really need it, remains to be seen just like the USB port. The charger works in any case properly and acts processed dibasic. Slowly, the Chinese have it really on it to produce such high quality products.
The two batteries must demonstrate whether they have enough capacity yet. However, they are much better than the original battery in the camera in their basic function. For that is the old model NP-BG1 that indicates the capacity of only as a bar. The two batteries of this package already meet the standard of the new Sony battery NP-FG1 and additionally show the remaining minutes.
Regardless of the yet to be tested longevity of the batteries I give before a clear recommendation!
IMPORTANT: In order to charge the batteries they must "wrong way round" (the rounded corners down) are inserted into the charger!
After three weeks of vacation, I can now say that the battery is at least as long as the original battery hold. And the car charger is a great thing. So the battery could recharge your batteries on the way to the next destination again. One use for the USB port, I had still not against it. But who better than need.
