19V 2.37A AC Adapter for Acer S7 and V3

This 19V 2.37A AC adapter is built for Acer S7 391, S7 392, V3-331 and V3-371 laptops. It supplies the exact voltage and current those models require. Owners of compatible ultrabooks can replace a lost or faulty charger with a matching unit.

Bundled power cord and tested unit

The package includes the adapter and a power cord cable so the charger works from a wall socket immediately. Each unit is tested before shipping to confirm it delivers the rated output. Buyers who need a different barrel size or a higher wattage brick will not be served by this kit.

3.0 mm by 1.1 mm barrel constraint

The connector measures 3.0 mm outer diameter by 1.1 mm inner diameter, so it only fits laptops with that exact jack. Polarity and dimensions must match the original charger or the laptop will not charge. Users with other tip sizes or centre-positive requirements must source a different adapter.

Questions about this item

How often should the 3.0*1.1mm tip be inspected for wear when used daily with an Acer V3-331?

Inspect the 3.0*1.1mm tip every few months for bent pins or loose fit; replace the adapter if the connector feels wobbly or charging becomes intermittent.

What component reaches its limit first during continuous 19V 2.37A output?

The internal electrolytic capacitors typically hit their thermal limit first under sustained full-load operation, causing ripple to rise before the adapter shuts down.

How warm does the brick get and does the fan run when powering an Acer S7 392 all day?

The brick runs warm to the touch with no fan; it relies on passive convection, so keep ventilation clear and expect surface temperatures above ambient during all-day use.
