Dual alarms, nap timer, adjustable night light, extreme battery back up system, what more could you ask for in a bedside alarm clock? How about a USB port to charge your mobile phone or portable music player, you say? Been there, done that. We included that too. The T128BC3 has two alarms that can be set and used independently, plus a separate programmable nap timer. Even the snooze alarm is programmable. The large 0.9" red display has a multi-level dimmer control, as does the concealed LED nightlight. We've included a CR2032 lithium back up battery that will back up your settings for up to 3 years and save you money on batteries. You probably keep your cell phone near your bedside at night anyway, so why not keep it fully charged and ready to go in the morning. Just connect the cable supplied with your phone to the USB port on the T128BC3 the ultimate convenience feature.
