This is a great device to have next to your bed. You can charge your cell phone wirelessly and thus have an alarm clock and a very nice bedside lamp. In short, 3-in-1! Do you like to take a nap after the alarm goes off? Just set the alarm clock snooze function. On top of the device is an anti-slip mat where you can wirelessly charge your smartphone or tablet if it supports the IQ standard. So you no longer need a separate charging cable. The warning light turns red while charging and changes to green when the battery is full again. The lamps work with 3 different light settings. They can burn continuously, they can change in brightness, and there is a mode where each light changes color slowly.
