A replacement for My BOOK 8TB Power Adapter


I need a power adapter for my My Book 8TB, so i contacted a seller to request an adapter with these specification:
12 Volts, 1.5 Amps, 18 Watts, 5.5*2.5mm.

The seller replied: you can choose 12V 3A(this choice is the best to meet your ask).

I did not find a 1.5 Amps. only 2 A and 3 A Available.

So what do you think is better to get, the 3A or the 2A?

I would go for the 3A , but 2A will be fine as well.

It all depends on the cost difference.
