Wireless Charging Kit for 13 and 14 Inch Notebooks

This Lenovo Go kit enables wireless charging for select non-touch 13 and 14 inch USB-C notebooks. It uses Energy Square Power-by-Contact technology to deliver power without cables. The silver charger is designed for professionals who want a cleaner desk setup. It suits users with compatible Lenovo models seeking cable-free convenience.

USB-C Receiver Dongle Requirement

The single specification that decides compatibility is the need for a specific USB-C receiver dongle. You must slide and lock this Rx dongle onto the bottom of a qualified notebook to connect the USB-C port. Only select non-touch 13 and 14 inch models support this connection method. Buyers with other notebook sizes, touchscreen models, or different charging ports cannot use this kit.

Dongle and Charging Pad Bundle

The kit bundles the wireless charging pad with the required USB-C receiver dongle. This combination changes the workflow by removing the need to plug in a power cable each time. You simply place the notebook on the pad after attaching the dongle once. The bundle ensures the proprietary contact alignment works correctly for efficient energy transfer.
