The iTekiro 170W AC adapter delivers 20V at 8.5A to compatible Lenovo ThinkPad mobile workstations. It replaces original 135W and 170W Lenovo chargers and includes a 6 ft AC cord plus a 6 ft DC cord. The unit accepts 100–240V input for worldwide use.

For ThinkPad P1 P50 P51 P52 W540 W541 owners

This adapter suits owners of the listed ThinkPad models who need a replacement 170W power supply. It does not replace the Lenovo 230W charger, so buyers whose laptop requires 230W should look at a higher-output unit instead.

170W output decides compatibility

The single specification that determines fit is the 170W output rating at 20V 8.5A. If the original charger is rated 135W or 170W this unit will work; if the system demands 230W it will not.

Questions about this item

Will the 6 ft DC power cord need replacing if the connector frays?

The 6 ft DC cord is fixed to the adapter body, so a frayed connector means the whole unit must be replaced.

What is the first limit reached when the adapter runs at 170 W continuously?

The over-temperature protection trips first if sustained 170 W output raises internal heat beyond safe levels.

How much heat does the 170 W brick produce when powering a ThinkPad all day?

The adapter meets UL safety limits and includes over-temperature protection, so surface heat stays within normal operating range during continuous use.
