  • TypeAC Adapters
  • Charges many brands with one adapter

90W Universal AC Adapter 15V-20V

This 90W universal AC adapter suits owners of Gateway, Toshiba, Fujitsu, HP, ASUS, Acer, Sony VAIO and other brands who need one charger for several laptops. It accepts 100-240V input and delivers up to 90W across multiple DC voltages. Buyers whose devices draw more than 90W cannot use this unit.

Plug-and-play with automatic voltage adjustment

The adapter detects the required output and switches between 15V, 16V, 18.5V, 19V, 19.5V and 20V without manual selection. Each brand uses several tip sizes for different models; the wrong tip will prevent charging. Contact the seller with your laptop brand and model number before ordering to confirm the correct tip.

Check your laptop power rating

Verify that the original charger is rated at 90W or below and that the required DC voltage falls within the 15V-20V range. Match the barrel connector dimensions to the tip supplied with this adapter. If the original unit exceeds 90W or uses a proprietary connector not covered, this adapter will not work.

Questions about this item

How do I confirm the charger is delivering the correct voltage after plugging it in?

The adapter automatically adjusts to the laptop's required voltage between 15V and 20V; check that the device charges and the power indicator lights up normally.

What comes in the box and which tips must be purchased separately?

The package includes the 90W universal adapter and power cord; brand-specific connector tips for models like ZenBook UX21E or HP Stream 14 are sold separately.

Which output setting should I select for a laptop rated at 65W?

The unit auto-detects and supplies the correct voltage up to 90W, so a 65W laptop will draw only what it needs without manual selection.
