135W Replacement Adapter for Lenovo Gaming Laptops

This 135W AC adapter supplies 20V at 6.75A for compatible Lenovo IdeaPad Gaming 3i and L340-17 models. It replaces original 90W and 135W Lenovo chargers and is built for users who need a direct power replacement. It is not suitable for systems requiring 170W or 230W input.

Extra Long UL Listed Power Cords Included

The package provides a 6 ft UL listed 3-prong AC cord and a 6 ft DC output cord, giving a combined reach that reduces the need for extension leads. Safety features include overload, short circuit, over voltage, over current and over temperature protection. A durable sealed case resists water and humidity.

Verify Your Laptop Model and Wattage Requirement

Confirm the exact model number matches the supported 81Y4, 81LL or L340-17 series listed in the specifications. Check that the original charger rating is 90W or 135W; this unit will not meet the demand of 170W or 230W configurations. Ensure the 20V 6.75A output matches the device label before ordering.

Questions about this item

Does the 6 ft DC cord or the 20 V 6.75 A barrel connector wear out first?

The barrel connector on the 6 ft DC cord typically fails before the cord itself, so inspect the tip for looseness after heavy daily use.

At 135 W continuous draw, does the 20 V 6.75 A output hit thermal limits before the overload protection trips?

The adapter’s overload and over-temperature protections engage together; sustained 135 W loads will trigger thermal shutdown before the overload circuit activates.

How much heat does the brick emit when it runs at 135 W all day?

The sealed, water-resistant case dissipates heat passively; expect the enclosure to become warm but not hot during continuous 135 W operation.
