WAWEIS 19V 90W AC Adapter for Acer Aspire 7740 7920

SKU CH-B1NS-K1PG8

19V 90W AC adapter with 10 ft cord and FCC, CE, RoHS certifications powers compatible Acer Aspire models

  • World-wide 100-240 V input works everywhere
  • 10 ft cord reaches distant sockets
  • Over-voltage, over-current and short-circuit protection
  • FCC, CE and RoHS certified safety
  • 100 % compatible with listed Acer Aspire models

What it is

This 19 V 90 W AC adapter replaces the original charger for Acer Aspire 7740 and 7920 series notebooks. It accepts 100–240 V AC at 50/60 Hz so it works on mains supplies worldwide. A 10 ft total cord length gives flexible placement at a desk or on a sofa.

Capacity and headroom

The 90 W output matches the factory rating for the listed Aspire models, delivering full charge speed while the system runs typical workloads. It will not support laptops that require higher wattage or a different voltage, so buyers needing more power for larger workstations should look elsewhere.

Thermals noise and power

Built-in over-current, over-voltage, short-circuit and overheating protections keep the adapter running within safe limits during normal use. The unit meets FCC, CE and RoHS standards and uses a smart chip to manage temperature without active cooling, so it operates silently.

Questions about this item

Will this 19V 90W adapter power my Acer Aspire 7740-5618 without issues?

Yes, the adapter is listed as 100% compatible with the 7740-5618 and other 7740 and 7920 models, delivering the required 19V 90W output.

How can I confirm the adapter is operating correctly after I plug it in?

The unit includes over-current, over-voltage, short-circuit and over-heating protection; a steady charge LED on the laptop indicates normal operation.

Does the package include the AC mains cable or only the adapter brick?

The charger ships with a total 10 ft power cord, so both the adapter brick and the mains lead are in the box.
