Compatible replacement charger

The ABLEGRID 45W AC adapter is built for the Lenovo N21 Chromebook series and matches part numbers GX20K02934 and 5A10H70353. It supplies 45W of DC power through a barrel tip connector and accepts worldwide AC input from 100 to 240V at 50 to 60Hz. The unit includes over-voltage and over-heat protection and carries CE, FCC and RoHS certifications. A detachable power cable is supplied in the box.

Upgrading from a lost or damaged original

This non-OEM charger replaces a missing or failed factory adapter without changing the voltage or tip geometry the laptop expects. The swap is worth it when the original unit is no longer available, shows physical damage, or trips its own protection circuits under load. Buyers who need a higher wattage rating or a USB-C output will not find those options here.

Fits into a minimal travel kit

The adapter plugs directly into any standard wall outlet and delivers the single DC rail the Chromebook requires, freeing the user from hunting for a proprietary brick. No extra drivers, docks or configuration steps are needed. Keep the ventilation slots clear during extended sessions and avoid placing the housing on soft surfaces that trap heat.
