Review on Female 7.4Mm X 5.0Mm To Male 4.5Mm X 3.0Mm DC Jack Adapter Power Connector Converter Cable For Dell HP Laptops And Computers by Suhas Carney

Revainrating 4 out of 5

Works for a M3800, mostly.

Powers a Dell Precision M3800, but will not charge the battery while it's on. I assume it doesn't recognize the charger as being authentic. Not a big deal for me as I bought it as a backup to leave in my backpack.

Pros
  • Item as described, fast shipping
Cons
  • May not be compatible with other laptop brands.
