Given that

Power rating (P) = 11 W,

Change in voltage (ΔV) = 8V ,

              We know that, P = ΔV . I

                                        I = P ÷ ( ΔV)

                                          = 11 ÷ 8

                                        I = 1.375 A

current used by camcorder is 1.375 A.
