Product identity and intended use

This iTekiro LEN.TAC150WLNSQ.NP5 AC adapter delivers 135 W at 20 V 6.75 A and replaces Lenovo 4X20E50559, 4X20E50560, 4X20E50561, 4X20E50562 and 4X20E50563 chargers. It accepts 100 to 240 V input at 50 to 60 Hz for worldwide use and includes a six-foot UL-listed AC cord plus a six-foot DC cord. The rugged case resists moisture and high humidity for mobile environments.

Who this suits and who should look elsewhere

Buyers needing a direct replacement for the listed Lenovo part numbers and 20 V 135 W output will find this adapter compatible. It does not replace Lenovo 170 W or 230 W chargers, so systems requiring those higher-wattage units cannot use this model. Users who need a different output voltage or connector type should seek an alternative.

Deciding specification

The single specification that decides fit is the 20 V 6.75 A 135 W maximum output matching the original Lenovo adapter ratings of 45 W, 65 W, 90 W and 135 W at the same voltage. Verify your device requires exactly 20 V DC and draws no more than 135 W before purchasing.

Questions about this item

What length are the AC and DC cords on this 135W adapter?

The UL-listed 3-prong AC cord is 6 ft and the DC output cord is also 6 ft, so you can reach distant outlets without an extension lead.

Which connector tip does the 20V 6.75A output use for Lenovo models?

The barrel connector matches the original Lenovo 4X20E50559 through 4X20E50563 adapters; align the centre pin before pushing it fully home to avoid bent pins.

Will the ruggedised case eventually need replacement due to moisture ingress?

The sealed case resists humidity and moisture, but inspect the cord strain reliefs periodically; if insulation cracks appear, replace the whole adapter.
