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.
