Functional product, lightweight effective. The internal adapter does not take up a lot of what I fear. The charging cradle is small (smaller than the phone), design and LEDs indicate the status of the load. At first glance seems loading fast. Functional product design, small and good value for money. I highly recommend this product if you are looking for this type of product. Just missing the transformer for power cord but micro usb / usb is provided in return. Tested on S3 i9305 4G.
