Our 40-amp JuiceBox Pro is ready to simply plug into any NEMA 14-50 outlet, and it works with all production EVs on the road today (it will automatically adjust to your EV and will output just as much power as your EV is able to accept). It offers faster charging and a set of advanced JuiceNet™ features that, in applicable geographies, pays you to charge!. The Pro 40 has the power to fast charge any present or future EVs. With the Pro, enjoy; energy metering, WiFi connectivity, scheduling, notifications, smartphone app, etc!


JuiceBox Pro is small and lightweight, and is fully ruggedized. With a host of available adapters, JuiceBox Pro can be used on the go and plug into nearly any electrical outlet available. JuiceBox is indoor & outdoor rated. Juicebox is just 11"x7"x3.5" and weighs ~21lbs with cable.


  1. More power and features for your money than any other charging station. There is simply no comparison!
  2. Emissions optimized: Our JuiceBox Green feature makes your JuiceBox grid informed, synchronizing with grid generation sources to make your charging as clean as possible! Wherever clean energy generation is available in the US, having a JuiceBox will mean a difference between an EV that's dirtier than a gasoline car and one that's cleaner. JuiceBox Green reduces CO2, NOX, particulate emissions, and hazardous mercury pollution, of which 50% is generated from coal-fired power plants.
  3. Can be used with any power source: Plugs into a dryer, RV-type or regular wall outlet with available adapters. Save hundreds of dollars on installation - just install a simple 14-50R outlet and you are ready to plug in your JuiceBox
  4. Great for both residential or on-the-road charging:  JuiceBox can be removed from the mounting bracket in seconds if you wish to take it with you as a portable charging option.
  5. Advanced energy metering & rewards:
    1. Energy, Voltage & Current measurements with 0.2% precision
    2. Persistent storage of energy data (data survives power interruption)
    3. JuiceBox Pro is also eligible in many areas for an upfront purchase discount and ongoing rewards. Learn more about JuicePoints.
  6. Built-in WiFi unlocks a host of advanced EVSE management features:
    1. Get access to your real-time and historical charging data on our website or through our beautiful SmartPhone App - Android or iOS.
    2. Control your JuiceBox from anywhere in the world, dynamically changing charging current and time-of-use schedule
    3. Use voice commands to get status and control your station via Amazon Alexa / Google Home voice integration
    4. Set up various automatic notifications, including: time-of-use in effect, start of charge, end of charge, unit offline, unit back online, car not plugged in by certain time in the evening, etc. - Access Our JuiceBox Control Room here
    5. Ensure your JuiceBox keeps correct time via automatic network sync
    6. If you have more than one EV, you can set up your two (or more) JuiceBox Pro units to share one electrical line! Say, you have only 40A capacity in your panel but have two Teslas (lucky you!). You can program your JuiceBox Pro units to never exceed 40A combined draw. If only one car is charging, it gets full 40A of current. When the second car shows up, the current gets shared 20A / 20A between the two. When one of the cars finishes charging, the remaining car ramps back to 40A. 
  7. Indoor and Outdoor rated: watch the EVSE Ice Bucket Challenge by Electric Motor Werks (it's worth it!)
  8.  from domestic and imported parts
  9. 3 year Warranty for Residential Use: Charge assured with a 3-year manufacturer's warranty for home usage.
  10. See our Return & Refund policy
  11. Installation: If you are looking for a qualified and experienced electrician, here is the list of our trusted electricians in California.
