Ulanzi CW15 Qi2 15W Wireless Charger Under-Monitor Dock

The Ulanzi CW15 is a wireless charger that attaches to the bottom edge of your monitor. Your phone snaps into place horizontally via a magnet—right where your eyes are already looking—and becomes a second screen displaying the time, weather, or calendar, without you having to unlock it. It charges via the Qi2 standard at up to 15 W; the cable runs through a hidden groove at the back, and you can control playback and volume with a rotary wheel from up to 10 meters away. The stand tilts within a 210° range .

Four features in one device

A magnetic charging surface, two USB-C ports, a rotary control with an LED indicator, and a mount for under the monitor. The charger thus takes up space that no one uses anyway—the bottom edge of the display.

15 W Qi2

Just place your phone on it and it charges—no need to search for a connector. The Qi2 standard delivers up to 15 W, so you can top off your battery throughout the day, even between calls. The 12 N magnetic force holds your phone securely in place, even while you’re typing on the keyboard.

A second screen you can just glance at

When placed horizontally, the phone displays the time, weather, calendar, or reminders without needing to unlock it. You have them in your field of view next to your monitor instead of on the desk beside it.

*The recommended height of the monitor above the desk is at least 10 cm.

Rotary dial for music and volume

Press to play or pause, turn to adjust the volume, and press again to skip a track. The controller works wirelessly up to 10 m and via Bluetooth 5.3, so it can even reach a computer behind the monitor.

210° Tilt Range

The stand tilts up to 210°, so you can adjust the angle based on your monitor’s height and whether you’re sitting or standing. Once tilted, it won’t get in the way even when you’re typing.

The cable disappears into a groove

There’s a cable guide on the back, so the charger’s cable doesn’t dangle across your entire desk. Five levels of circuit protection monitor temperature and current to prevent your phone’s battery from aging faster than necessary.
