What is the idle power consumption of the JuiceBox?
 

Approximate idle power consumption of the JuiceBox is about 2.4W/h, equal to about 2 kilowatt hours per month.  If you pay .15 per kWhr, it would cost an additional .30 to keep your JuiceBox plugged in and transmitting.

This definition considers the idle state as being when the unit is not outputting power charging a vehicle, but is powered on. 

Break down of draw contributing to idle consumption:

  1. On-board hardware level processing of EVSE safety and signalling (sub 600mW)
  2. Telemetry
  3. Reporting and metering (low frequency - sub 1W)
  4. On-board flash memory R/W (sub 600mW)
  5. On-board indication LEDs (the remainder)
