45W USB-C AC Adapter

Who this suits and who it does not
This adapter suits owners of compatible ThinkPad USB-C devices who need a replacement or spare charger for home, office, or travel. It is not for laptops that require more than 45W, devices with proprietary barrel connectors, or users needing multiple simultaneous outputs.
Deciding specification: 45W output
The single specification that decides fit is the 45W power rating. Match this figure to the power requirement printed on your device or its original supply. If your hardware demands a higher wattage, this adapter will not provide sufficient power.

Questions about this item
How do I connect the 45W USB-C adapter to my ThinkPad and what is the common mistake?
Plug the USB-C connector into the ThinkPad's USB-C power port and the AC plug into a wall outlet; the common mistake is using a USB-C data-only cable or port that does not support power delivery.
What part of the 45W USB-C adapter will need replacement first?
The detachable AC power cord or the USB-C cable typically wear out before the adapter brick itself.
What thermal limit appears first during sustained 45W charging?
The adapter's internal over-temperature protection will throttle output if the brick overheats during continuous full-load operation.
