90 W 19 V laptop adapter

This 90 W AC adapter delivers 19 V at 4.74 A through a 5.5 x 2.5 mm barrel connector. It accepts 100–240 V input at 50/60 Hz and ships with a two-prong US power cord. The unit carries CE, UL and RoHS certifications and is supplied new.

For replacement chargers only

Suitable for owners of listed Toshiba Satellite, Acer Aspire, Compaq Presario, Compaq Evo and CTX EZBook models needing a direct replacement. Builders of desktop systems or users of laptops requiring a different voltage, current or plug size should select another unit.

5.5 x 2.5 mm barrel connector

The decisive specification is the 5.5 x 2.5 mm DC jack; only devices with an identical connector diameter and matching 19 V 4.74 A rating will work. Verify the original adapter’s output and plug dimensions before purchase.

Questions about this item

How do I install the 5.5x2.5mm connector and what polarity mistake should I avoid?

Align the 5.5 mm outer diameter and 2.5 mm centre pin, then push straight in until the barrel seats fully; the tip is positive and the barrel negative, so reversing them will prevent charging.

Which parts of this 90 W adapter are likely to need replacement after extended use?

The detachable US two-prong cord and the DC cable near the 5.5x2.5 mm plug are the wear points; the brick itself is sealed and not user-serviceable.

At what load does the 19 V 4.74 A output hit its thermal limit during sustained operation?

Continuous draw at the full 4.74 A (90 W) will trigger the internal over-temperature protection first, causing the unit to shut down until it cools.
