    Product Description

    The 50-amp OpenEVSE station is ready to plug into any NEMA 14-50 outlet, and it works with all years of the Tesla Model S and Model X. It offers fast charging and more features like a beautiful full LCD screen that the Tesla factory cable doesn't have.

    It is perfect for customers who need to replace their factory Tesla charging cord. Get yourself an OpenEVSE Charging Station and support the open source hardware/software movement.

    1. More power and features for the money than any other charging station
    2. Can be used with any power source: Plugs into a dryer, RV park or regular wall outlet with available adapters. Save hundreds of dollars on installation - just install a common NEMA 14-50 outlet and you are ready to plug in your OpenEVSE
    3. Great for both Home or on-the-road charging: OpenEVSE can be removed from the wall via slotted screw holes in seconds if you wish to take it with you as a portable charging option. OpenEVSE is just 8.75"x5"x3.5" and weighs ~12lbs with cables.
    4. Indoor and Outdoor rated


    It will charge your Tesla at up to 40A. However you can dial it back to whatever you have for a supply such as a 30A Dryer outlet or a 20amp A/C outlet (adapters available from me)


    The OpenEVSE may be set in multiple steps between 6A-40A in 2 amp increments. This advertises the available current to the EV which intern draws what it is designed for. You can go into the menu and set it for less if you take the EVSE on the road with you to fit what you may find in the wild.


    This unit is constructed with a 50A power input cable and a 50A contactor. It is built to plug into a common 14-50 outlet used in RV parks and Range/Oven’s

    • It has a nice Blue LCD display.

    If you would like this unit customized with a twist lock plug for example or something other than the NEMA 14-50 plug I can do that for the difference in parts. For example a L15-50. This would allow you to use many adapters. I also build custom adapters, Please email me with your custom request.


    Custom order possibilities:

    I get a lot of inquires about custom builds. YES I definitely take orders for anything you would like to see in your EVSE. Example I can build this one here for the same price and make the Whip longer for only a few dollars a foot up to 50ft. Please see the Custom category.


    Works with the following vehicles
    Tesla Model S (all years)
    Tesla Model X (all years)

    It will charge a Tesla at up to 40 amps.
