Target device and purpose

This AC adapter is built for the Lenovo N21 Chromebook and matches the GX20K02934 and 5A10H70353 part numbers. It supplies 45 watts at 20 volts and 2.25 amps through a 3.0 by 1.1 millimetre round tip. Buyers needing a different tip size or a higher wattage unit should look elsewhere.

Input range and connector constraint

The unit accepts 100 to 240 volts at 50 to 60 hertz for worldwide mains use. The 3.0 by 1.1 millimetre round tip is not compatible with the larger 4.0 by 1.7 millimetre round tip found on some other Lenovo models, so the correct connector must be verified before purchase.

Build safeguards and package contents

The adapter includes protection against incorrect voltage, short circuit and internal overheating. The package contains one AC adapter and one detachable power cord for immediate use.
