300 W AC adapter for Legion laptops

This 300 W power supply replaces the original Lenovo adapter for Legion 5, 7 and Pro models with 15, 16 or 17 inch screens. It also fits ThinkPad P series workstations and Yoga AIO 7 desktops that require the same 20 V 15 A output. The unit is built with certified components and carries FCC, CE and RoHS approvals.

Sustained-load behaviour

Over-current, over-voltage, short-circuit and total-power protection circuits guard the adapter during continuous high-draw sessions such as gaming or rendering. A smart chip monitors temperature and activates overheating protection before components reach critical limits. High-quality wiring and improved isolation materials reduce electrical interference under steady load.

Replaces original 300 W Lenovo units

The adapter matches part numbers ADL300SDC3A, ADL300SLC3A, GX21F23045 and the 5A10W86289, 5A10W86290, SA10R16956, SA10R16957 series. It is a direct swap when the original unit fails or a spare is needed for travel. Buyers whose devices require more than 15 A or a different voltage should not use this model.
