I totally misunderstood. the description of this clock. It is not rechargeable. it does come with a USB cord, but it does not come with a wall plug. knocks it down quite a few pegs. it does have a battery, but it's only for backup if the power goes out. and does not allow you to see the display. I certainly can make this work, but not as I had hoped. The things I like about this alarm clock. the color changing ability, the dimming and the ease of setting the time. it has four options for sound machine for sleep, but they're just okay. they're not good quality sound. if I was to choose a different alarm clock I would choose one that is battery powered full-time. That would allow me to put the alarm clock anywhere I actually liked instead of within cables reach of an outlet. The instructions are a bit vague. they could have used more diagrams, especially when it came to installing the backup battery.
