iTekiro 135W AC Adapter for Lenovo Slim 7

The iTekiro 135W AC adapter supplies 20V at 6.75A for the Lenovo Slim 7 7i 16IAH7 82VB and ThinkPad X1 Extreme Gen 3 models listed as 20TK variants. It replaces Lenovo 135W and 90W chargers with a slim plug tip and extra-long cords. Buyers needing 170W or 230W output cannot use this unit.

Power delivery limits of the barrel connector

The barrel connector provides up to 135W and does not support higher-wattage Lenovo adapters rated at 170W or 230W. A UL listed 6 ft AC cord and a 6 ft DC cord give extended reach without extra extensions. The adapter includes overload, short-circuit, over-voltage, over-current and over-temperature protection.

135W maximum output decides compatibility

The single specification that determines fit is the 135W maximum output; systems requiring 170W or 230W will not operate correctly with this adapter. The 20V 6.75A rating matches the original Lenovo 135W and 90W chargers for the listed Slim 7 and X1 Extreme models.

Questions about this item

Is this 135W adapter the right replacement for my Lenovo Slim 7 16IAH7?

Yes, it matches the 20V 6.75A 135W specification required by the Slim 7 16IAH7 and replaces the original Lenovo 135W or 90W charger.

Will my laptop charge at the full 135W rate with this adapter?

The adapter delivers 20V at 6.75A for a maximum of 135W, so your Slim 7 will charge at its designed speed when the system requests full power.

Does the 20V output work with the standard barrel connector on ThinkPad X1 Extreme models?

It uses a slim plug tip designed for the listed X1 Extreme Gen 3 and 20TK series part numbers, not the larger legacy barrel connector.
