Portable EVSE options for 220-240V beyond 16A charging.... 24A, 32A etc.

Hello All,

I am starting this thread to answer a specific question: Options for portable charging that go beyond the 16A (derated 20A circuit) units that are quite available these days.

I have found a couple and I would like peeps input on these or suggestions for others. Important considerations are also:
-- can you dial back the unit to tell your EV to charge at a lower rate, so that you can plug into a source with less than max rate charging?

Some 2013-2014 owners are lucky to have a robust unit that can upgraded to 25A 240V charging, but others need to pursue alternatives.......

120-240V 16-30A $400 https://www.evseadapters.com/en/for-evse-upgrade/132-new-16-30a-adjustable-120-240v-charger-evse.html

Thats a good deal as it's $100 more at Amazon:

Another option for 20a and portable would be this from Juicebox, $449:

Also VegasBrad sells many OpenEVSE models starting I believe <$400, he has a listing here on MNL.
Of course Clipper Creek also sells many portable models that output up to 32a and are priced >$500.

I'm a little leary of that Khons as the way you change the charging current is to "shake" the EVSE......also not even 1 person has reviewed it on Amazon even though it's been listed for many months.....personally I'd rather adjust output current with a push button or trim pot, that or the juicebox units adjust with your cell phone I believe. Lastly if you only plan on carrying around one EVSE in your car I'd be a bit worried that the Khons only goes down to 16a, no way thats going to work on a 15a standard household outlet. I believe the Juicebox or OpenEVSE models go all the way down to 6a. It's also why I'd not be that fond of the Clipper Creek models, not only are they fixed on their output current but they only work on 240v, not also 120v.

I have not used that khons charger, just found it and thought the price was attractive. I agree that having to shake it to change charge current is stupid and would be a deal breaker.
I also found that for less than $300 it is possible to build your own 40 amp EVSE using OpenEVSE essential parts and good quality Yazaki 30A cable from Amazon (branded as Leviton A2034-PEV for $150).

JuiceBox Pro 40 A will allow you to dial back using your smart phone.

JESLA is programmable from 12 to 40 amps by just swapping the interchangeable plugs. No knowledge of electricity required. Works with all electric vehicles, 100 volts to 264 volts. Truly portable, unlike many that claim to be portable.

http://shop.quickchargepower.com/JESLA-is-THE-40-amp-J1772-portable-charging-solution-JESLA.htm

JESLA will further limit the maximum power to whatever plug is used. You don't need to know anything about electricity; it's Just-Plug-N-Charge (TM) !!!

NEMA 5-15 ......Standard Outlet... 12 amps ... adds 3-4 miles per hour charging

NEMA 6-15 ...... Air conditioners..
12 amps ... adds 6-8 miles per hour charging

NEMA 5-20 ...... Motel A/C .......... 16 amps ... adds 4-6 miles per hour charging

NEMA 10-30......Older Dryers........ 24 amps (discontinued, we can make an adapter for NEMA 14-30) ... adds 15-20 miles per hour charging

NEMA 14-30......Newer Dryers...... 24 amps... adds 15-20 miles per hour charging

NEMA 14-50......RV Parks ............ 40 amps ... adds 25-30 miles per hour charging

NOTE: JESLA comes with a carrying case, and NEMA 5-15 and NEMA 14-50 plugs.

If you have a current leaf and you have upgraded wiring with a 30A socket the leaf can charge at 120V at full capacity. But why? If you have to run the wiring for a given current 240V is twice as fast as 120V. On a standard 15A household circuit the supplied L1 charger at 12A is the NEC maximum. To me a 240V EVSE makes more sense.

Agree but one reason one might want to charge at 27.5a @120v is in the case of a TT-30 outlet. Many campgrounds or other places catering to RVs may only have a TT-30 outlet(along with a 15 or 20a standard outlet). In the case of a TT30 you should be able to safely charge up to 24a which would be twice as fast as the stock Leaf EVSE or the same as 12a @ 240v, a definite plus over a standard 120v outlet. But I agree if installing an outlet yourself why bother with 120v, 240v is the way to go.

To me charging at an RV camp is the only reason for 120V charging. I satisfied myself that my 2013 Leaf could charge at full current from 120V but it was only an experiment. I normally charge in my garage at 240V. My Mercedes B charged at 40A and my eGolf charges at 30A.

For my curiosity I may see what the maximum for my eGolf at 120V. I know from hearsay that the B maxes out at 20A. High current 120V is not for me.

$97 off the normal(somewhat high IMO) $449 retail. At $351 for a 18 footer and $319 for the somewhat short 12 footer it's not much more than the run of the mill $299 16a EVSEs. It has a somewhat uncommon 6-30 plug but I guess it could be replaced and being by a major mfg. like Leviton it's UL listed.
If I had a older Leaf EVSE I'd probably go the upgrade route and get the same 20a(and also ability to charge at 120v) but for the newer upgrades that only go up to 16a, this is probably the cheapest 20a EVSE, for sure the cheapest UL listed EVSE.

As usual with Amazon, prices vary by the day if not hour, no idea how long this price will last....
