135W AC/DC Adapter for Lenovo

This 135W AC/DC adapter delivers 20V output for compatible Lenovo laptops. It accepts worldwide input voltage from 100 to 240VAC at 50 or 60Hz. The unit is built as a direct replacement charger for the listed device models. It is supplied new with 100% OEM compatibility guaranteed.

10 Ft Power Cord and Safety Protections

A 10 ft power cord provides extended reach from the mains outlet to the laptop. Safety features include over current protection, total power protection, over voltage protection and short circuit protection. The adapter uses high quality wires and smart chip overheating protection. Anti-interference isolation materials further protect connected equipment.

135W to 170W High Power Capacity

Rated at 135W with support up to 170W high power, the adapter handles demanding laptop workloads. It runs out of headroom when the connected device draws sustained power beyond the 170W ceiling. Buyers who need more output for larger workstations or multi-device charging should consider a higher-wattage unit.

Questions about this item

Will the 10 ft power cord or the AC connector need replacing after extended use?

The 10 ft cord is built with high-quality wires and overload protection, so it should not require replacement under normal conditions.

What is the first limit reached when this 135W adapter runs at full load continuously?

The 135W output rating is the hard ceiling; sustained draw above that will trigger over-current and total-power protection.

How much heat and fan noise does the 20V 135W unit produce when left plugged in all day?

No fan is present; the adapter relies on passive cooling and smart-chip overheating protection to stay quiet during all-day operation.
