Pros & Cons

Pros

  • ✓ 12V 2A output matches Seagate FreeAgent, Backup Plus, Expansion and WD My Book bricks
  • ✓ Five-way protection: over-temp, short-circuit, over-voltage, over-current, over-load
  • ✓ AC 100-240V 50/60Hz input works on both US and overseas outlets
  • ✓ Lists exact OEM part numbers (WA-24E12, DA-24B12, ADS-24S-12) to check against

Cons

  • ✗ 5.5 x 2.5/2.1mm center-positive jack only; wrong-size barrels will not seat
  • ✗ Buyer must verify the OEM part number themselves, since drive models overlap
  • ✗ 2A ceiling rules out drives that shipped with a 3A or higher brick
  • ✗ ycwwzzh is an unbranded seller, not a Seagate or WD licensed accessory
