Exact volts and amperes

Hi, I need the exact amount of power (volts and amperes) to turn on my cloud home duo. I need to know if my power adapter is not enough powerful (even if it is the original one) or if my product has problems. Europe standards.
Thanks

My Cloud Home Duo (4TB, 6TB, 8TB, 12TB) … 12 Volts / 3 Amps / 36 Watts

My Cloud Home Duo (16TB) … 12 Volts / 4 Amps / 48 Watts
