I am also interested, but the didn't specify via e-mail to me.
Would also like to know the type of jacket on the cords(picture of the designations would do) Please and thanks.

The cord from the wall outlet to EVSE is 10 gauge and a stiffer vinal, which does get quite stiff in cold temps. Luckly it's only a couple feet, so it's not that big of a deal. The wire from the EVSE to J1772 is a very nice rubbery cord, it's metric but when I converted it, it came out to be a tad thicker than 10 gauge, very nice as mine is 8m long. The only drawback of the rubbery cord is it gets dusty if ran across a dusty/dirty garage floor, but it's easily wiped clean with a damp cloth. Even though it's ~10 gauge, it coils up quite nicely, at least the J1772 cable :)

Thanks for the quick response .
10 gauge is good for 7200W so thats ok.
The rubber EVSE to J1772 cord is it type sj or sow? ( If you can picture with designations would be nice.)
I guess the other major concern to me and you might have to to the cord cap off to find out is if they crimped or soldered the 14-50 supply plug
( hopefully its not just stripped wire under a screw, again picture would be nice.)
None of this info was supplied to me from them and that is why I havn't purchased one yet.

Here's a pic of my plug

It's stripped wire that's been soldered on the end and then clamped via the plug screws

JJeff, Thanks for the feedback on the 6a and on the Juicebox Pro. I am not crazy about having "internet" only access to this. I wish they would build a simple wifi web interface on these things so that you can connect and manage it locally. Are there other options that people recommend? I was looking at the Chargepoint EVSE also, but I was hoping to future proof this just a little if I can with the 40amp option on the Juicebox pro or something similar. I like the option to be able to monitor, track, and manage charges, monitor the power consumption, charging, and historical data as I feel those are very useful tools. If there are other options out there that fit that description let me know. I am still looking at my options.

I didn't think about the 6a being too low, I hope it will still work for those times when you need a charge and don't have other options. It is the crisis mode charging level for when there aren't any other options. Something is better than nothing idea. :)

I'm not aware of any EVSEs that are as sophisticated as the Juicebox Pro, the Zencar EVSE gives you a instantaneous and total Kwh reading, but unfortunately clear once unplugged.
I believe I read Juicebox is working on a way to directly connect to the EVSE with WiFi but as of now it's internet only and somehow through their servers. When someone asked what happened if their servers went down, their response was they had a very redundant system, of course no internet connection, no way to change the output current as of now. Again you can use the EVSE, you just can't change the output current from it's last setting.

I think you'll be OK with 6a, EVSEupgrade goes down to a 6a setting and I've never heard of anyone having a problem with it. I believe 6a is the lowest current allowed with the J1772 standard EVSEs use.

Thanks for the photo.
I guess that type of termination would be ok if you keep your eye on it (use a infrared thermometer to monitor)
I might add some better form of restraint
I also see the type of cord jacket is VW-1 which a 105 c and 600V rating. Confirm or correct me if not the case.

You're over my head now, I don't even know how to identify VW-1 jacket

The EVSE cost really depends on your cost. I find that I can build the whole thing for $350. I I purchased resistors at Orvac the cost would be much higher China parts are cheap but 6 week si a killer. you really have to stock the parts

This is a test of 2-phase 6kW charger (with my Wife's Leaf 30kWh) - real speed at input is 5,8 kW/h.
Of course you need 3-phase power at home, but every phase (of two used) is loaded with about 13A, so no problem with fuses.

EVI Dual Voltage Multiple Current Portable EVSE

A little over a week ago I got a new portable EVSE. It’s an EVI Deluxe Dual Voltage EV Portable Smart Charger Plus, $319 from Amazon. I’ve only used it a half-dozen times, but I’m very happy with it.

You can use it on 120V or 240V, and set the current to 8, 12, or 16 amps. It comes with a L6-20 (240V, 20A) plug and two adapter cables, one to a 5-15 plug (120V, 15A, the one I use the most) the other to a 14-50 plug (50A).

At home I have a 120V 15A outlet and at work a 120V 20A outlet, which allows me to charge about 33% faster (16A vs 12A).

I really like the display. It shows the voltage at the outlet, so you can see how much it drops when you start charging (then if the size of the drop makes your uncomfortable, you can switch to a lower current). It also shows the current being drawn (so you may catch when you’re near the end of the charge and the current drops significantly). It also shows the total kilowatt-hours for the charging session and the duration of the session. Lastly, it shows the internal temperature and the charging current you selected.

So for a bit over $300 I now have a back-up EVSE that I leave in the car, while the original one stays mounted on the wall of my garage.

FYI. Judging from the display and adapter cables, I think this is electrically the same as some Khone, Evolution, and MUSTART EVSEs, and very similar to some from Zencar or Jekayla.
