Cord Length and Safety Features

The package includes a 6 ft UL listed 3-prong AC power cord and a 6 ft DC power cord for extended reach without extra cables. Internal protection filters input voltage spikes and limits output voltage or current to guard the laptop. A ruggedized case resists moisture and high humidity during travel.

Simple Installation Limits

Connect the AC cord to a 100 to 240V outlet and the DC plug to the laptop; the adapter works whether the system is on or off. It replaces genuine 90W, 135W and 170W Lenovo chargers but will not support models requiring a 230W or 300W power supply. No software or drivers are needed.

Questions about this item

Does the 6 ft DC cord or the barrel connector need periodic replacement?

The adapter uses a fixed 6 ft DC cord with a barrel connector; no user-replaceable tip is mentioned, so the whole cable assembly would be replaced if the connector wears out.

Will the 170 W rating sustain continuous load without thermal throttling?

The unit is rated for 170 W maximum output at 20 V and 8.5 A; sustained loads at or near that limit will generate heat inside the ruggedised case, which is the first constraint under continuous use.

How much heat and fan noise does the brick produce during all-day operation?

There is no fan; the sealed ruggedised case relies on passive cooling, so the brick runs silently but will become warm to the touch when delivering up to 170 W continuously.
