Graviton ADP-90FE D 90W USB-C Power Adapter

SKU CH-YYAH-E3E18

90 W USB-C charger delivers 20 V at 4.5 A and steps down to 15 V, 12 V, 10 V, 9 V or 5 V for compatible laptops

  • 90 W output charges laptops quickly
  • Multiple voltage steps from 5 V to 20 V match device needs
  • 100–240 V input works worldwide
  • USB-C connector fits modern ports
  • CE certified for safety compliance

What this adapter powers

The Graviton ADP-90FE D delivers 90 W over a USB-C connector. It accepts 100-240 V input at 50-60 Hz, making it suitable for worldwide mains voltages. The unit targets MSI laptops that charge through USB-C Power Delivery profiles. Builders needing a barrel-plug tip or a higher wattage brick should look elsewhere.

What the bundle adds

The package includes the adapter and a detachable mains cord with EU, US, UK or AU plug options. No extra cables, docks or software licences are supplied. The cord simply lets the brick connect to local wall sockets without a separate travel adapter. Users wanting a spare cord or a longer cable must source them separately.

Limits of the USB-C PD implementation

The adapter negotiates fixed voltages of 5 V, 9 V, 10 V, 12 V, 15 V and 20 V with matching currents up to 4.5 A at the top level. It cannot exceed 90 W total output. Devices that require adjustable PPS steps, voltages above 20 V or power beyond 90 W will not charge at full speed. Cable quality and length may further reduce available current.

  • Multiple voltage steps from 5 V to 20 V match device needs
  • 100–240 V input works worldwide

Questions about this item

How often will the Type-C plug on the ADP-90FE D need replacing under daily use?

The USB-C connector is rated for thousands of insertion cycles, so typical daily plugging should not require replacement for years.

What limits the 90 W output first when the adapter runs continuously at full load?

The 20 V 4.5 A maximum current ceiling is reached before any voltage headroom is exhausted, capping sustained output at 90 W.

How warm does the 90 W unit get and how much power does it draw from the wall when charging a laptop all day?

At 100-240 V 50-60 Hz input the adapter draws roughly 90 W plus efficiency loss, and the enclosure warms to a noticeable but safe temperature during continuous operation.
