Replacement 170W adapter for Legion laptops

This iTekiro 170W AC adapter replaces the original Lenovo 135W and 170W chargers for Legion Y545, Y7000 and Y720-15IKB models. It supplies 20V at 8.5A to power the laptop and charge the battery whether the system is on or off. The unit accepts 100 to 240V AC input at 50 to 60Hz for worldwide use. It does not replace 230W or 300W Lenovo chargers.

Extra-long cords and safety features

A UL-listed 6 ft 3-prong AC cord and a 6 ft DC cord give extended reach without needing extension leads. Internal protection filters input voltage spikes and limits output voltage and current to guard the laptop from electrical hazards. High power efficiency delivers consistent, continuous power. A ruggedised, tightly sealed case resists moisture and high humidity in mobile environments.

170W maximum output decides compatibility

The adapter provides a maximum of 170W at 20V DC, 8.5A, matching the original 135W and 170W Lenovo units for the listed Legion models. Buyers whose laptops require a 230W or 300W charger cannot use this adapter. Dimensions are 6.18 x 3.31 x 1.97 inches and weight is 26.50 oz including cords.

Questions about this item

Will the DC cable or barrel connector on this iTekiro 170W adapter need periodic replacement?

The unit ships with a 6 ft DC cord permanently attached to the ruggedised case; no user-serviceable connector is mentioned, so the whole adapter would be swapped if the cable fails.

What thermal or current limit kicks in first when this adapter runs at 170W continuously?

The adapter is rated for a maximum of 20V at 8.5A (170W) with an input range of 100-240V 50-60Hz; sustained operation at that output is the design limit.

How much heat and fan noise does the 6.18 x 3.31 x 1.97 in brick produce under all-day load?

The sealed, fanless enclosure relies on passive cooling; no acoustic or surface-temperature figures are published for continuous 170W operation.
