• 45W on a 65W system (Lenovo FAQ HT508527) Lenovo 45W USB-C portable adapter FAQ Published note Max output is 45W. On a 65W system you may see slow charge or battery drain under load; Lenovo says use the bundled adapter when the system needs more than 45W. Many 90W+ systems reject 45W input Shopping note Match the printed Chromebook wattage — do not downsize from a 65W Chromebook brick to a random 45W phone cube under load
• Not USB-C PD replaceable Barrel / proprietary round tips on older Lenovo notebooks Do not confuse Modern Lenovo Chromebook USB-C classes above charge over USB Type-C. Older Lenovo notebooks and many high-watt Windows bricks still use a round barrel or proprietary tip — that tip is not replaceable by a USB-C PD GaN alone.
