Universal 90W charger with fifteen tips

This 90-watt AC adapter ships with fifteen interchangeable barrel tips covering a wide range of laptop brands. A smart chip detects the attached tip and automatically selects the correct output voltage between 18.5 and 20 volts at up to 4.74 amps. The unit accepts 100-240 volt AC input at 50-60 hertz for worldwide mains compatibility.

Tip selection replaces multiple proprietary bricks

Each tip matches a specific barrel size and voltage pair such as 4.8 by 1.7 millimetres at 18.5 volts or 5.5 by 2.5 millimetres at 19 volts. Swapping the tip changes both the physical fit and the voltage the adapter delivers, so one unit can replace several manufacturer-specific chargers. Users must verify their laptop's required tip against the printed compatibility list before use.

Maximum 90-watt output limits supported devices

The adapter tops out at 90 watts, so any laptop whose original charger exceeds that rating will not charge correctly or may drain under load. Buyers needing more than 90 watts for larger workstations or gaming notebooks should look for a higher-capacity supply.

Questions about this item

Will the 15 interchangeable tips wear out and need replacing after frequent swaps?

The 15 tips are passive connectors without moving parts; normal insertion and removal cycles do not degrade them, so replacement is not expected during the adapter's service life.

What stops the 90 W output from being sustained continuously?

The adapter is rated for a maximum of 90 W (20 V at 4.74 A); drawing more than this limit triggers the built-in protection and reduces output.

How much heat or fan noise appears when the charger runs at full load all day?

The unit has no fan and relies on passive cooling; at full 90 W load the case becomes warm but remains within normal operating temperature for a sealed AC adapter.
