45W AC charger for Lenovo Chromebook N21

This 45W AC charger supplies 20V at 2.25A to Lenovo Chromebook N21 models including 80MG, 80MG000US and 80MG001US. It accepts a 100-240V 50-60Hz input so it works worldwide. The 3.0x1.1mm round tip matches the original connector exactly. Buyers whose devices use a 4.0x1.7mm tip or USB-C cannot use this unit.

3.0x1.1mm tip and bundled power cord

The package includes the adapter and a matching AC power cord ready for immediate use. The fixed 3.0x1.1mm round connector eliminates guesswork and prevents accidental connection to incompatible ports. No software or driver installation is required. Users with USB-C charging laptops or the larger 4.0x1.7mm barrel will need a different supply.

Safeguard circuitry and global voltage input

The adapter incorporates protection against incorrect voltage, short circuit and internal overheating to shield the Chromebook during daily charging. Its 100-240V 50-60Hz input range handles mains variation without a separate voltage selector. The compact brick plugs directly into a wall outlet or power strip. Travellers heading to regions with different plug types will still require a local mains adapter.
