DC adapter for 5.5 × 1.7 mm laptop ports

This connector changes a 5.5 × 2.5 mm male plug so it fits a 5.5 × 1.7 mm female jack. It also accepts the common 5.5 × 2.1 mm size, so one adapter covers two frequent barrel variants. Builders repairing or extending a laptop power lead can use it without soldering. The part is sold new as a single piece.

Passive barrel connector with no active electronics

The adapter adds no circuitry, so it introduces no extra heat, noise or power draw. Current simply passes through the metal contacts from the male plug to the female jack. Normal use stays within the cable's original rating. No fan, driver or configuration is involved.

Questions about this item

How do I connect the 5.5×1.7 mm female jack to my device without reversing polarity?

Align the centre pin of your device's 5.5 mm barrel socket with the adapter's female jack; the 1.7 mm pin fits only one way, so it cannot be inserted backwards.

Will the male plug's 5.5×2.5 mm tip wear out and need replacement?

The solid brass tip resists deformation; under normal indoor use it maintains contact for years without needing replacement.
