Compatible AC Adapter for Acer Travelmate B3

This 45W power supply delivers 19V at 2.37A for the Acer Travelmate B3 series including TMB311-31-C343, B311-32, TMB311-31-C3KH, TMB311-31-C7D6, TMB311-31-P1L1, TMB311R-32-C31R, TMB311RN-32-C6ZX and Spin B311RN-32 models. It accepts 100-240V input at 50-60Hz for worldwide use.

Replaces Lost or Faulty Original Charger

The adapter substitutes a missing or damaged factory unit for the listed Travelmate B3 and Spin B311RN-32 laptops. The upgrade is worth it when the original charger no longer provides stable 19V output or the power cord is frayed, restoring full charging capability.

Limited to Barrel Connector Devices

The unit uses a fixed barrel plug and 19V output, so it cannot charge laptops that require USB-C Power Delivery or a different voltage. It is unsuitable for devices needing more than 45W or a proprietary connector not matching the Travelmate B3 series.

Questions about this item

Will the 19V 2.37A connector fit my Acer Travelmate B3 TMB311-31-C343?

Yes, the adapter is built for the Travelmate B3 series including TMB311-31-C343, B311-32, TMB311-31-C3KH, TMB311-31-C7D6, TMB311-31-P1L1, TMB311R-32-C31R, TMB311RN-32-C6ZX and Spin B311RN-32 models.

What is the step people forget when installing this 45W charger?

Connect the IEC power cord to the adapter brick first, then plug the barrel tip firmly into the laptop before switching on the mains socket.

When should I replace the power cord that comes in the box?

Replace the cord if the insulation cracks, the plug pins bend, or the adapter trips its overcurrent protection during normal 19V 2.37A operation.
