Restore external power capability to compatible Acer notebooks with a 45 W adapter that provides 19 V DC output at up to 2.37 A. Its 3.0 mm x 1.1 mm connector tip is the critical physical compatibility point: verify the notebook’s original adapter label and DC input jack before replacement. The adapter and cable are supplied together for a complete external-power assembly. PA-1450-26-OPC suits replacement and spare-power roles for Acer notebook systems using this voltage, current, and tip combination. A 45 W output rating supports systems specified for this adapter class without substituting a different connector geometry. Matching the connector dimensions matters alongside electrical output, since a visually similar barrel plug may not mate correctly with the notebook power jack. Within the PA-1450-26 adapter designation, this version is defined by its 19 V, 2.37 A output and compact 3.0 mm x 1.1 mm tip. Those values distinguish it from adapters intended for notebooks with larger barrel connectors, different voltage requirements, or higher power demands. Use it where the existing adapter’s printed ratings and connector size correspond to these specifications.
