USB-C Dock for ThinkPad X390

The Gintai CS18 docking station provides a USB-C charging port built specifically for the Lenovo ThinkPad X390 series. It restores the single connection point that handles power delivery and peripheral expansion for this ultraportable lineup. The unit is supplied new and matches the exact port layout required by the X390 chassis. Installation is a direct replacement with no adapter cables needed.

Replaces a damaged or lost CS18 port

If the original USB-C charging dock has failed or gone missing, this part returns the laptop to full docking capability. The upgrade is worth it when the existing port no longer negotiates power or drops video signals during use. Buyers who need additional video outputs, extra USB-A ports or Ethernet on a different connector should look elsewhere, as this dock replicates the factory CS18 specification only.

Questions about this item

Will the CS18 docking station fit my ThinkPad X390 without extra brackets?

The CS18 is built to match the X390 chassis, so it aligns directly with the USB-C port and sits flush without additional mounting hardware.

What is the installation step that people most often miss?

Insert the dock squarely until the USB-C connector clicks fully into the X390 port; a partial insertion leaves the charging circuit inactive.
