J+ Portable Level 2 EV Charger, 40 Amp, 240V, 9.6kW, J1772 EV Car Charger, NEMA 14-50, ETL Certified, IP67 Waterproof, 21ft Cable, Indoor/Outdoor Charging Station

I like the portability and the options to easily change the wall connector. I also like that there isn't a stupid app to deal with if I'd like to change change limits! It's a self contained device. Feels solid.Was a bit on the pricey side when compared with permanent L2 charges, but I'm happy to pay more for something that's safer and better quality and also portable. Case it comes with isn't great (zipper is low quality) but I don't pack it up much. Probably would subtract at least half a star for that and price, but I'm rounding up. :)

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+.

Update 2: I have changed my review to 5 stars. I had a qualified electrician come out and he determined the issue was with the circuit. The wires were loose which connected to the receptacle and that caused excessive heat. The charger was found not to be at fault. Additionally, I did contact j+ booster customer service and they were very helpful. They asked good questions to help determine the problem and even offered to speak with the electrician while he was at my house. Due to the charger not being at fault and the great customer service, I changed from 1 to 5 stars.UPDATE 1: THE CHARGER NOW GETS HOT EVERYTIME IT CHARGES AND EMITS A STRONG BURNT PLASTIC SMELL. I THINK IT IS FAULTY AFTER 10 MONTHS OF USE. I AM IN THE PROCESS OF CONTACTING CUSTOMER SERVICE. BEWARE!!!Original: I like the charger. It’s versatility is great and length is sufficient but could be longer. I purchased back in September and have been using it ever since to charge 2 vehicles routinely. No issues…until today.10 months in, during this extreme heat wave, I had to charge one of my vehicles for a long trip. The high has been about mid-90s lately and as the charger plugs in my garage, it has been about 105+. I have always used 40 amps, no problem and given that my receptacle is rated for 50 amps, I never thought this would be a problem. Well, after about 2 hours of charging, I had to leave and was going to remove the plug and take it with me but the plug was too hot to touch. When I finally (safely) removed it, it had melted the plastic face of the receptacle and some of the plastic residue fused onto the plug. It had overheated! The plug and entire cable were hot to the touch. No warning whatsoever from the charger or my vehicle. The charger should have at least cut off to avoid the potential for an electrical fire. I’m very fortunate I checked when I did.Regardless, I will now me charging at 32 amps from now on. CAUTION.

PROS: Good design & solid material.CONS:>Too short cable: Cable is only 17' ??>Plug side cable is too short only 6 inches long.>Plug connector and the cable got very hot 122F ; even in summer days it may be hotter, so I thought this was not safe.>Not a functional APP>Cable is very stiff at the mean time only 10AWG (5.3mm2) which is not enough for a 40Amp circuit max can use 32Amp on AWG-10 wire that is why it gets very hot.>I wonder how UL gave a certificate for a 10AWG cabled charger, where it needs 40amp 8AWG wire.> looks like previous returned item shipped to me; items shipped had sing of previous return had a lot of box wear out.Looks like I am retuning it; not long enough cable for me I need at least 21' and it is not safe for me to use with thin cable!

I've been using mine for a year and a half now both mounted on my home and removed to take on the road for vacation charging (RV campground 40 amp NEMA 14-50 stations available). Solid with plenty of opportunity for the user to customize with a large number of snap-in heads. I'd buy it again.
