SlimTouch 4050 compact wireless keyboard

The Adesso WKB-4050UB is a 78-key US-layout keyboard with an integrated multi-gesture touchpad. It connects through a USB 2.0 receiver using 2.4 GHz RF technology with 65536 IDs across 12 channels. The slim scissor-switch design keeps the profile at 0.75 inches thick. It suits home-theatre PCs, kiosks or any setup where a separate mouse is impractical.

30-foot range with two AAA batteries

The keyboard operates up to 30 feet from the receiver and draws power from two AAA batteries. The built-in touchpad measures 3.00 by 3.50 inches and supports multi-finger gestures without driver installation. This covers typical living-room distances and eliminates the need for an extra pointing device. Users needing longer range or rechargeable power will find those options absent.

USB 2.0 receiver with 2.4 GHz RF link

The sole connection is a USB 2.0 dongle measuring 0.70 by 0.50 by 0.25 inches. There is no Bluetooth, wired or alternative wireless interface. Verify that the host system has a free USB 2.0 port and supports standard HID keyboard and mouse input before purchase.

Questions about this item

Will the 2.4 GHz USB receiver work alongside my older USB 2.0 peripherals without conflict?

Yes, the receiver uses 65536 IDs across 12 channels to avoid interference with other wireless devices on the same USB 2.0 bus.

How can I verify the touchpad gestures are active after plugging in the receiver?

The 3.00" x 3.50" touchpad supports multi-finger gestures without any driver installation; test two-finger scroll and pinch-to-zoom immediately after the receiver is recognised.

Does the box include the two AAA batteries the keyboard needs, or must I buy them separately?

The keyboard requires 2 AAA batteries for power; they are not included, so you will need to purchase them separately.
