The ThinkPad 4X20E50558 is a 135W AC adapter for ThinkPad laptops with a rectangular Slim Tip power connector, suitable for owners who need a replacement or spare adapter. Confirm your laptop uses Slim Tip rather than a round barrel-type plug before choosing it.
Recommended For
- ThinkPad owners replacing a failed or missing 135W adapter, provided their laptop uses a rectangular slim-tip connector and Lenovo lists this adapter as compatible.
- People who leave a compatible ThinkPad set up in more than one place—such as at home and at work—and want a separate adapter at each location.
- ThinkPad Universal USB-C Dock users whose setup needs a 135W slim-tip adapter to support the dock’s specified 100W notebook charging.
- ThinkPad users who want a spare adapter to keep in a carrying case for powering or charging a compatible slim-tip laptop away from their main workspace.
Real-World Use Scenarios
- If a compatible ThinkPad’s original charger is lost or stops working, use this as a replacement; Lenovo says it performs to the same specifications as the standard adapter supplied with compatible laptops.
- For someone who works at home and in an office, keeping one adapter at each desk can avoid packing and unpacking a charger; plug it into a wall outlet to power the compatible ThinkPad and recharge its battery.
- When traveling with a compatible ThinkPad, keep this adapter in a carrying case as a dedicated power source; at a destination with a wall outlet, it can power the laptop and recharge its battery.
- Before buying it for a particular ThinkPad, check the laptop’s power connector: this adapter is for the rectangular slim-tip port, so it will not work with models that have a round barrel-type power plug.
