Purpose & Fit

This new AC adapter replaces the LITEON Nexstgo PA-1650-90 unit and delivers 19 V at 3.42 A for a total of 65 W. It suits owners of compatible laptops that require the 4.5 mm by 3.0 mm barrel connector.

Capacity & Limits

The 65 W rating covers typical ultrabook and thin-and-light workloads such as web browsing, document editing and video playback. It will not sustain high-performance discrete-graphics loads or charge the battery while the system draws maximum power under heavy compute tasks.

What the Bundle Changes

The package includes a 12 month warranty with a 60 day free replacement or refund period. The supplier states 100 % OEM compatibility and invites buyers to confirm fit when the original part or laptop model number is absent from the published list.

Questions about this item

Will the 4.5 mm × 3.0 mm barrel connector on this PA-1650-90 adapter fit the charging port on my older LITEON Nexstgo laptop?

The adapter uses a 4.5 mm outer and 3.0 mm inner diameter barrel tip rated for 19 V 3.42 A, matching the original PA-1650-90 specification for compatible LITEON Nexstgo models.

How can I verify the adapter is delivering the correct 65 W output after I plug it in?

Check that the laptop charges normally and the battery icon shows mains power; the brick is built to supply 19 V at 3.42 A for a total of 65 W.

Does the box include a mains cable for UK sockets or do I need to buy one separately?

The package contains the new AC adapter unit only; a standard IEC C5 / C7 mains lead for your region must be sourced separately.
