DBTLAP 19V 2.37A AC Adapter

This DBTLAP adapter supplies 19V at 2.37A for compatible Acer Aspire ultrabooks. It includes the adapter unit and a mains power cord in the box. The barrel connector measures 3.0mm outer by 1.1mm inner diameter. Buyers should verify the tip against their original unit before ordering.

Replaces worn or lost Acer 19V chargers

The unit matches the original 19V 2.37A specification for the listed Aspire models. It serves as a direct replacement when the factory charger fails, is lost or shows cable damage. Each item is tested before shipping to confirm correct output. The jump is worth it when the original adapter no longer delivers stable power.

Handles 19V 2.37A ultrabook loads

The adapter comfortably powers the supported Aspire S7 series notebooks under normal workloads. It runs out if the device demands more than 2.37A at 19V or if the connector polarity and dimensions do not match exactly. Users with different voltage or tip requirements cannot use this model.

Questions about this item

Will the 3.0 mm by 1.1 mm barrel tip fit my Acer Aspire S7-392 charging port?

Yes, the adapter uses a 3.0 mm outer diameter and 1.1 mm inner diameter barrel connector that matches the Aspire S7-392 and 9890 models.

Do I just plug the IEC C7 mains lead into the brick and the barrel into the laptop, or is there a polarity switch to set?

Connect the supplied figure-8 mains cord to the adapter, then insert the 3.0 mm barrel into the laptop; the tip is centre-positive so no switch is needed.

How long before the 19 V 2.37 A brick or its detachable mains cord typically needs replacing?

The adapter and its IEC C7 cord are rated for several years of daily use; replace either piece if the barrel becomes loose, the cord frays, or output voltage drops below 19 V.
