Hello all. I need a power supply for the Canon 60d to run it continuously in a photobox. I have a China adapter. At startup it always shows the message: "Connection with battery not possible / Use this battery?". As soon as I confirm this with OK, the camera works perfectly. But I don't want my customers to have to fiddle with the camera and I'm looking for a solution that doesn't require this confirmation. Before I spend 200 CHf, my question is: Does the original DC Adaper establish a connection to the camera so that the camera starts without confirmation (identical to the battery)? Thank you for your efforts, greetings Sascha
