Tevelmick 19V 3.42A 65W ac adapter 3.0*1.1mm

SKU CH-YWEZ-5PW2X

Replacement 19V 3.42A 65W charger with 3.0*1.1mm tip for Acer Chromebook and Aspire models

  • Delivers 65 W output for fast charging
  • 11 ft extra-long cable gives flexible placement
  • 0×1.1 mm pin fits snugly in listed Acer models
  • CE, FCC and RoHS certified for safe operation
  • Includes 48 in AC cord and user manual

Power supply for Acer Chromebooks

This 19V 3.42A 65W AC adapter replaces the original charger for a wide range of Acer Chromebook models including the C720, C740, CB3-431 and CB5-571 series. It also supports Aspire S5 and S7 ultrabooks that require the same voltage and connector. The package includes the adapter, a 48-inch AC power cable and a user manual.

3.0*1.1mm barrel connector with multi-voltage output

The critical specification is the small-pin 3.0*1.1mm barrel plug that must match the laptop charging port exactly. This unit delivers 19V at up to 3.42A for 65W maximum, while also regulating down to 19V 2.15A 40W or 19V 2.37A 45W for models that draw less current. Using an adapter with a different pin size or voltage will prevent charging or risk damage.

Stable output during extended charging sessions

Oxygen-free copper in the power cord reduces resistance so the adapter maintains its rated voltage without excessive heat buildup during long charge cycles. The unit carries CE, FCC and RoHS certifications, confirming it meets safety and emissions standards for continuous operation. It is designed to charge the battery at the same speed as the original supply without throttling under sustained load.
