Wish you had a real-time energy price display? Powered by any standard USB wall charger or computer USB port, Energystats large lighted LCD display and 2 ultra-bright multi-colour LEDs show a digital clock-calendar and real-time electricity time-of-use prices and billing periods. Visible up to 50 feet away, the LEDs show the current price period (left) and pending next price period (right flashing); RED is ON-PEAK. AMBER is MID-PEAK, GREEN is OFF-PEAK Energystat saves the time of looking up time-of-use periods and prices on the internet or on a utility bill, and can help make more timely choices for load-shifting to mid-peak or off-peak hours. Its precision clock-calendar is kept alive for up to 6 years by its 3V battery when unplugged from USB power, and even adjusts itself for daylight savings time every March and November. Includes 3V battery, USB power cable, USB wall charger, and user manual, and is pre-programmed for the Ontario time-of-use prices set by the Ontario Energy Board. Programming for other Canadian provinces can be provided on request.
