Review on 🔌 Enhanced Cable Drive Adapter Converter Support for Optimal Performance by Jose Strong

This adapter comes with a 12V power supply. You must use the AC adapter with the laptop. Notebook power supplies do not provide enough power to operate the adapter without a power supply. Desktop computers do not have this problem. The desktop power supply has enough voltage and current to power the hard drive. Bottom line, this adapter works great to turn an old hard drive into an external hard drive. The price is very reasonable for what it is and does.
