Purpose-built replacement

The ABLEGRID 20V 3.25A 65W charger is a non-OEM power adapter designed for the Lenovo Ideapad 100-15IBY 80MJ N2940. It supplies 20V at 3.25A through a 4.0mm by 1.7mm barrel tip. Worldwide AC input from 100 to 240V at 50 to 60Hz makes it suitable for travel or home use.

Build and daily handling

The unit carries CE, FCC and RoHS certifications and includes over-voltage and over-heat protection. A standard barrel connector mates securely with the laptop port, while the detachable AC cable allows easy storage or replacement. The adapter runs on DC output and ships with a new power cable in the box.

Upgrade context and limits

This adapter replaces a lost or faulty original charger for the specified Ideapad model. It restores full 65W charging without requiring a higher-wattage brick. Buyers who need a different tip size, a higher current rating, or a USB-C power delivery solution should look elsewhere.

Questions about this item

Does the 20 V 3.25 A output deliver the full 65 W my Ideapad 100-15IBY expects?

Yes — 20 volts at 3.25 amps equals 65 watts, matching the original adapter rating for the N2940 model.

Will the 4.0 mm by 1.7 mm barrel tip fit the charging port on my Ideapad 100-15IBY?

The connector is a 4.0 mm outer diameter, 1.7 mm inner diameter barrel tip built for the Ideapad 100-15IBY 80MJ series.

How do I install the charger, and what step do people often miss?

Plug the AC cable into the brick, insert the barrel tip firmly until it seats, then connect to mains — the common mistake is leaving the tip slightly loose.
