J+ Portable Level 2 EV Charger 40 Amp (J1772, 9.6KW) - 240V Electric Vehicle Charging Station with NEMA 14-50 & 5-15 Plugs - ETL Certified, IP67 Waterproof, 25ft Cable for Indoor/Outdoor Use - Perfect for Home, Office & Road Trip Charging

I had to return my first unit as it didn't seem to work but J+ customer support were fantastic and incredibly responsive. I even got a discount on my 2nd unit. This really is the best portable charger out there, and it comes with a bracket to make it a fixed one at home if you want. It really is very sturdy, though that does also mean its heavier. As you will find on the internet people have driven over these with pickups and they still work. Well, I have not, and will not try that. But compared to my KIA OEM and another aftermarket brand unit this one does look like it will survive multiple droppings on concrete etc. without any issues. Comes with a separate 120V and a 240V connection cable so you can use either type outlet which is nice. Just be careful the sleeve on the connection between the control unit and the short 120 or 240V cable "positively" connect and clicks. You'll find out quick enough if it hasn't anyway as with the weight of the control unit, it will pull apart with gravity, and unit won't work anyway if connection not correct. Its nice to be able to set it for a multitude of current settings up to 40A in case you need that variable capability. Comes in a very nice case (though large) to fit the whole unit. Only minor gripe is that the rubber cover on the J1772 end is a little snug to get off and on, but then it probably makes it much more weatherproof. Has been great doing 120V at home indoors and 240V at work outdoors (and in the sleet/snow this week). Supposedly its been tested after dunking in several feet water. Its also UL rated.Its a little pricey compared to some others but even the 21ft system ( I have the 25) is still a little longer than some others but I think it is well worth the $$ and should last a lot longer than others especially if used outside and exposed to the weather. You can buy a lock to ensure the unit can't be removed from the wall holder (if you use that) or someone can't disconnect the wall outlet cable from the control unit (stops the connecting sleeve sliding to unlock). Shout out again to Greg and the great customer support at J+.
