Ruth's sister 5.5 x 2.5 mm International Power Cord Black

DC 5.5 x 2.5 mm power cable

This international power cord uses a 5.5 x 2.5 mm DC barrel connector to link a compatible laptop charger to the mains lead. It is intended for users who need a replacement or spare cable for Lenovo, Toshiba or Acer adapters that accept this jack size. The black cable provides a direct connection between the power supply brick and the AC inlet. Builders who require a different barrel diameter or a proprietary connector cannot use this item.

Passive cable with no active cooling

The cord contains no fan or active components so it produces no audible noise during operation. It draws only the power required by the attached adapter and adds no measurable thermal load of its own. Normal use involves routing the flexible black cable between the power brick and the wall socket without any heat or acoustic concerns.
