The RC571 Digital Alarm Clock Radio with Large Numbers and USB Charging from RCA has a compact design and is ideal for nightstands, desks or any small surfaces. The large, easy-to-read display can be seen from across the room. With a built-in USB port, you can charge a device overnight. Wake to your choice of FM radio or alarm. With the dual wake alarm, you can set 2 alarms as needed and, of course, hit the snooze if you need a few extra minutes. This digital clock radio also provides a "No Worry" backup battery option, so if power shuts off, your alarm still alerts you. The backup option requires 2 AAA batteries, sold separately.
