Review on 🔌 DTech Slim USB to Hard Drive Cable HDD SSD 3.5 2.5 Inch 22 pin SATA to USB 2.0 Adapter: Speedy Disk Data Transfer with Power Supply and LED Indicators by Polo Bradley

If you use this device with a 2.5 inch hard drive, it works fine. BUT, if you want to use this device with a 3.5" drive, you need to connect the included power cable. This device cannot be powered. If you have a 3.5 inch hard drive, you will need the supplied external power adapter to transfer data to and from the hard drive (3.5 hard drive) with this device.
