Compact 45W power for Yoga and IdeaPad

The Lenovo GX20K11838 is a 45W AC adapter built for various Yoga and IdeaPad notebooks. It supplies the rated output to charge the internal 6 cell lithium-ion battery. A black wall-mountable brick keeps the cable run short at the outlet.

Fixed 45W output limits multi-device use

The adapter delivers a single 45W rail with no selectable voltage steps shown in the data. It cannot power larger laptops that demand higher wattage or simultaneous charging of multiple devices. Users needing more headroom must choose a different unit.

Lightweight brick suits daily carry

At 0.35 lb and measuring 1.14 by 2.36 by 3.54 inches the adapter fits in a carrying case without bulk. The wall-mount plug eliminates a separate cord to the socket, reducing desk clutter. No detachable cable is mentioned, so the AC lead is fixed to the body.
