104-key USB wired keyboard

The Adesso AKB-139EB is a standard-layout wired keyboard connecting via USB. It features a 104-key US layout with blue LED backlighting that can be toggled on or off. The keys carry 2x large print for high contrast visibility. Low-profile choc keycaps reduce travel distance and help prevent accidental keystrokes.

Suits low-light offices; not for palm-rest users

This keyboard suits users who type in dim environments and want larger key legends without glare. The fixed blue backlight and large print aid legibility in studios or offices. Buyers who need a built-in palm rest, wireless freedom, or per-key RGB control should look elsewhere. No mouse is included.

USB wired connection

The single deciding specification is the USB wired interface. It requires an available USB Type-A port and draws power directly from the host. The keyboard supports Windows 2000 through Windows 10. If your system lacks a free USB port or runs a non-Windows OS without USB HID support, this model will not work.

Questions about this item

What comes in the box with the Adesso AKB-139EB and do I need to buy anything else to use it?

The box contains the keyboard only. No palm rest or mouse is included. It connects via USB so no separate cable or adapter is required.

The specs list a 104-key US layout — is that the only version available for this model?

Yes, the AKB-139EB is offered solely with the 104-key US layout. No alternative layouts or key-count options are listed for this model.

How does the blue LED backlight perform when I am typing in a dim room?

The blue LED backlight is bright and evenly distributed across the keys. It can be switched on or off, and the 2x large-print legends provide high contrast for low-light typing.
