90W 19V AC Adapter for Toshiba Laptops

This 90W power adapter delivers 19V at 4.74A through a 5.5x2.5mm barrel connector. It is built as a direct replacement charger for a wide range of Toshiba Satellite and Satellite Pro series notebooks listed in the compatibility data. The unit is supplied new with a standard EU mains plug.

Input Range 100 to 240V 50 to 60Hz

The adapter accepts a universal AC input from 100V to 240V at 50Hz or 60Hz, drawing up to 1.8A. This wide range allows operation on mains supplies worldwide without a voltage selector switch. The fixed EU plug means a travel adapter is required for non-European socket types.

Check Tip Polarity and Model Match

Before ordering, verify that the laptop requires a 5.5mm outer diameter and 2.5mm inner diameter tip with centre-positive polarity. Confirm the exact model number appears in the supported list, as other Toshiba models may use different tip sizes or voltage ratings. Buyers needing a different connector size or higher wattage cannot use this unit.

Questions about this item

Which of the listed compatible Toshiba models matches my laptop so I know this adapter is the right one?

The adapter is compatible with Toshiba Satellite A100, A105, M40X, M60, M65, 1100, 1105, 1110, 1115, 1130, 1135, 1900, 1905, 1950, 1955, 2430, 2435 series and specific sub-models such as A100-151, A105-S101, M60, 1115-S103, 1135-S155, 1905-S302, 1955-S801, 2430-S255.

What does the 90 W output power mean when the adapter is connected to my laptop?

It delivers up to 90 watts at 19 volts and 4.74 amps, which is the maximum power the brick can supply to charge the battery and run the system simultaneously.

What does the 5.5 x 2.5 mm barrel connector cap in practice for this adapter?

The 5.5 mm outer and 2.5 mm inner diameter tip fits the DC-in jack on the listed Toshiba models, so the physical connection is limited to laptops that use that exact barrel size.
