Questions about this item

Does the iTekiro 65W adapter ship with both the AC power cord and the DC cable, or must I buy one separately?

The package includes a 6 ft UL-listed 2-prong AC power cord and a 6 ft DC power cord, so nothing extra is required to plug in and charge.

My Lenovo originally came with a 45W charger; will this 65W unit work safely?

Yes — the adapter outputs 20V at 3.25A for 65W maximum and is designed to replace both 45W and 65W Lenovo chargers, but it does not replace a 90W model.

What does the 65W rating mean when the adapter is actually connected to my IdeaPad S540?

It means the brick can deliver up to 20V and 3.25A continuously, powering the laptop and charging the battery at the same time whether the system is on or off.
