Genuine Acer 90W AC adapter

This 90 watt adapter delivers 19 volts at 4.74 amps for compatible Acer Aspire laptops. It is a new genuine Delta Electronics unit identified by a blue tip measuring 5.5 millimetres by 1.7 millimetres. The adapter replaces a long list of Acer part numbers including ADP-90SB BB and PA-1900-24. It is intended for owners of the listed Aspire models who need a direct replacement charger.

Input range and connector fit

The unit accepts 100 to 240 volts at 1.5 amps across 50 to 60 hertz, so it works on mains supplies worldwide without a voltage selector. A blue tip confirms the correct polarity and diameter for the supported Aspire series; a black tip indicates a different connector that will not fit. Orders shipped to the US and Canada include a power cord, while other destinations receive the adapter only.

Sustained output behaviour

Under continuous load the adapter maintains its rated 90 watt output at 19 volts and 4.74 amps without exceeding the specified input current. The design targets stable voltage delivery during extended charging and operation sessions typical of daily laptop use. It is not suitable for laptops that require a higher wattage or a different tip configuration.

Questions about this item

What sustained load causes the 90W output limit to be reached first?

Continuous operation at 19V and 4.74A draws the full 90W rating, so any workload that keeps the laptop at maximum charge and performance simultaneously will hit that ceiling.

How much heat and noise does the adapter produce when running all day?

The brick is passively cooled with no fan, so it generates only the warmth expected from a 90W supply at 100-240V input and stays silent during extended use.

Which Acer laptop models and tip style must I already own for this adapter to work?

It fits Aspire models such as 3040, 3820G, 3830TG, 4220, 4520G, 4740G, 4820TG, 4930G, 5520G, 5530G, 5540, 5550, 5560G and others that use the 5.5mm x 1.7mm blue tip.
