Re: Can i change external HDD's power adapter 12v 1.5A to 12v 2A?
Hi
Welcome to Tech Support forums. (Well, I am a user as new as you)
Coming to your question, Yes, you can definitely use the 2A charger with your hard drive. Ampere ratings tell you how much you can load the charger with before it is 'overloaded'. Current is load, not the output. The output is the voltage. The thing you need to be careful about is the output voltage rating, which you mentioned is the same for both the adapters. So, you will be fine using the 2A charger in place of the 1.5A one.
Hope that answers your question.
