Product Description

Our 50-amp OpenEVSE station is ready to plug into any NEMA 14-50 outlet, and it works with all production EV’s on the road today. It offers faster charging and more features like a nice LCD at a far lower price than any of the competitors.

It is perfect for customers who are tired of long slow charging with their stock “brick” chargers. I can speak from personal experience; my 2013 LEAF went from 24 hr charge time down to 5 hours! Don’t pay the dealer $1500 for an AeroVironment 30A charger with NO LCD that’s permanently on the wall. (That’s what many including myself have been quoted!) 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 and on-the-road charging: OpenEVSE can be mounted on the wall via slotted screw holes and removed in seconds if you wish to take it with you. OpenEVSE station is just 7.5"x4.5"x3" and weighs ~10lbs with cables.
  4. Indoor and Outdoor rated


It will charge any J1772 compliant car at up to 40A. However you can dial it back to whatever you have for a supply.


The EVSE 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.

Runs on 120v and 240v, switches automatically. Plugs into ANY outlet with adapters!

This unit is constructed with 50A components and a 63A J1772 plug. It is built to plug into a common 14-50 outlet used in RV parks and Range/Oven’s, Plus with its 14-xx universal plug it can also plug into NEMA 14-30 Dryer Outlets found in homes built in 1996+,  as well as the NEMA 14-60 outlet found at some fairgrounds.



  • 120v/240v auto switching
  • OpenEVSE main board
  • 25ft. Custom 50A J1772 "Whip" with 63A high current plug and PET braided sleeving. Additional footage available

You can even use the PlugShare app and set the filters to include NEMA 14-50 and see all of them in the country, there are a surprising number of them.
  • It has a nice Blue LCD display.
  • I used a metal blue lighted ring Menu/Select button. With IP65 water resistance rating
  • Heat shrink tubing used throughout.
  • All parts are new.



    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 6-50 plug. 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.
