Replacement charger for System76 Lemur Ultra

This ABLEGRID AC-DC adapter is built for the System76 Lemur Ultra model lemu4. It accepts worldwide AC input from 100 to 240 volts at 50 or 60 hertz and delivers DC power through a barrel tip. The unit includes over-voltage and over-heat protection and carries CE, FCC and RoHS certification.

Upgrading from a lost or failing original adapter

It replaces the factory charger when the original is missing, damaged or no longer holds a stable output. The jump is worth it when the laptop will not charge, shuts down under load or the tip no longer seats securely. A non-OEM unit restores full charging function without waiting for a manufacturer back-order.

Capacity and headroom for daily use

The adapter supplies continuous DC power for typical office work, web browsing and media playback. It runs out of headroom if the system draws more current than the brick is rated for, which can happen during sustained heavy compile jobs or gaming sessions. Long-term use requires adequate ventilation and a dry environment.
