Ruth's sister DC 7.4x5.0mm Female to 5.5x2.5mm Male Internal Power Cable 15cm
Two-piece adapter cable converts a 7.4x5.0mm female DC jack to a 5.5x2.5mm male plug over 15cm for Asus and Toshiba notebook chargers
- Converts 7.4×5.0 mm female to 5.5×2.5 mm male for adapter compatibility
- 15 cm cable keeps internal routing tidy and compact
- Two-piece pack provides a spare for multi-device setups
- 15 g lightweight design adds minimal mass inside the chassis
- Female 5.0 mm inner and male 2.1 mm inner match common barrel dimensions
Connector Adaptation
This adapter converts a 7.4mm outer by 5.0mm inner female DC jack to a standard 5.5mm outer by 2.5mm inner male plug. It suits users who need to power a device with a 5.5 x 2.5mm input from an existing Asus or Toshiba style charger tip.
Thermal and Power Profile
The 15cm cable adds negligible resistance so voltage drop stays minimal during normal charging currents. No active components mean zero fan noise and no extra heat beyond the adapter bodies themselves. The lightweight 0.015kg construction keeps strain on the source port very low.
Build and Daily Use
Each pack contains two identical cables for spare or multi-device setups. The short length reduces clutter inside a laptop bag or behind a desk while still bridging the connector mismatch. Simple plug-in action requires no tools or driver installation.

Questions about this item
How do I install the 7.4x5.0mm female to 5.5x2.5mm male adapter cable inside a laptop chassis?
Align the 7.4mm outer and 5.0mm inner diameters of the female socket with the laptop's DC-in jack, then insert the 5.5mm outer and 2.1mm inner male plug into the power brick tip; the 15cm wire length requires routing near the motherboard edge.
What maintenance or replacement will the 15cm internal power adapter cable need over time?
Inspect the solder joints at both the 7.4x5.0mm female socket and the 5.5x2.5mm male plug for cracking after repeated thermal cycles; replace the cable if the connector barrels loosen or the 15cm wire insulation shows wear.
What is the first limit that appears when the 7.4x5.0mm to 5.5x2.5mm converter runs under sustained load?
The 15cm wire gauge and the 2.1mm inner pin diameter on the male end limit current capacity before the 7.4x5.0mm female socket or the 5.5mm outer barrel reach their thermal limits.
