Dell HH44H 90W AC adapter is a mains power supply designed to deliver stable DC power to compatible Dell laptops and portable devices. The adapter converts AC input to a regulated 90-watt DC output to charge the notebook battery and power the system during operation. It features an integrated output cable and a compact brick-style housing intended for everyday use at home, in the office, or while travelling.

Advantages

Its compact form factor and standard connector simplify replacement or spare-parts use. The unit is engineered to meet typical safety and efficiency expectations for laptop power supplies and supports continuous operation under normal load conditions.

Suitable for

• Charging compatible Dell laptops that require up to 90 watts
• Replacing a lost or faulty AC adapter at home or in the office

How to use

Ensure the adapter’s input rating matches the local mains voltage, then connect the mains plug to a suitable power outlet.
