Replacement AC Adapter for Toshiba

This new AC adapter supplies 8 V at 2 A through a 5.5 mm by 2.1 mm barrel connector. It is built as a direct replacement for Toshiba models that use the AC-SR3 part number. The unit ships in white and carries a 12-month warranty with a 60-day free replacement or refund period.

Suitable for matching Toshiba laptops

Buyers whose original adapter matches the 8 V 2 A output and the 5.5 mm 2.1 mm tip can use this unit. It will not suit laptops that require a different voltage, current rating or connector size. Always verify the original part number before ordering.

8 V 2 A output with 5.5 mm 2.1 mm connector

The single specification that decides compatibility is the 8 V 2 A output delivered through the 5.5 mm by 2.1 mm barrel plug. If the original power supply lists those exact figures, this adapter is the correct part.

Questions about this item

Will the 5.5mm by 2.1mm barrel connector on this E-buy AC-SR3 adapter wear out or need replacement after long-term daily use?

The 5.5mm by 2.1mm barrel connector is a standard passive component with no moving parts; it does not have a service interval and only needs attention if physical damage occurs to the tip or cable.

What is the first limit reached when the E-buy AC-SR3 runs continuously at its rated 8V 2A output?

Continuous operation at the rated 8V 2A output stays within the adapter's design envelope; the first practical limit is the thermal protection built into the unit, which will activate only if cooling is obstructed.

How much heat and noise does the E-buy AC-SR3 produce when powering a laptop all day?

The adapter has no fan, so it runs silently; under all-day load it warms to a typical external temperature for a sealed 8V 2A supply and relies on its plastic case to dissipate heat.
