After the original power supply was laid for our HDR-PJ30VE of our son, we ordered for short-term use of this. The first charging process worked flawlessly. The battery charges while the camera is not used here. Once it is turned on, the power supply switches to the device itself, and interrupts the charging process. However, this is no problem for us - it was important that the battery in the camera can also be charged without any additional equipment. Meanwhile, the original is indeed resurfaced, but we keep this as a replacement. For Seller: The power supply was verschcikt super fast. Thank You :)
