Vertical Ergonomic Design

The J-Tech Digital V638W is a wireless mouse shaped for medium to large right hands. Its vertical orientation encourages a natural handshake grip that reduces wrist and forearm strain during extended work sessions. A removable, non-skid palm rest attaches magnetically to limit drag and sweat buildup on different surfaces.

Dual-Mode Connectivity

Connect via the included 2.4 GHz USB dongle or pair over Bluetooth to a second device. A dedicated mode switch on the underside toggles between the two links without software. The rechargeable 800 mAh cell charges through USB-C, so the mouse stays operational across long days without disposable batteries.

Adjustable DPI and Remappable Button

Sensitivity cycles through 800, 1200, 1600 and 3200 DPI steps to match cursor speed to the task. The “Back to Desktop” button sends Win+D on Windows and Command+D on Mac; users can remap it with third-party tools such as Karabiner-Elements. The white finish resists visible wear in daily office use.

Questions about this item

Does the V638W get warm or noisy after running all day?

The vertical ergonomic mouse has no moving parts or fan, so it stays silent and does not generate noticeable heat during extended use.

What must I already own for the V638W to work?

You need a device with a free USB-A port for the 2.4 GHz dongle or built-in Bluetooth, plus a USB-C power source to recharge the 800 mA battery.

Will the V638W work alongside my older USB 2.0 peripherals?

Yes, the 2.4 GHz dongle plugs into any USB-A port and operates independently of other USB 2.0 devices, while Bluetooth mode leaves the port free entirely.
