The adjustable Duosida is my spare that I keep in the car with the 2 adaptors I made, it's not my primary EVSE. Being that it's not my primary I just couldn't justify the added $100 to $150 more for the next step up (Zencar) which does have that 24amp setting which is perfect for 30amp max circuits if usage of such is regular.
While at work I plug into a 14-50R (208v commercial 2 out of 3-phase used) which so far has been it's only use besides testing the other voltages and amp settings at home. And yes I did test it on my TT-30 at home running for 1 hour at the max rate the leaf can pull of 27.5 amps. No issues and heat was verified with an infrared thermometer on feed wires, breaker, & EVSE plug & cord. Same operating temps I see running at 240v 27.5 amp on 40 amp breaker.
Regarding the TT-30 (120v 30amp) option... We are talking emergency on the road oh crap I'm running out of juice because I didn't plan ahead better or non-operational public charging stations. I've owned recreational vehicles for 18 years... 24 amp max continuous is rare in campgrounds... Someone needs to inform the RVIA and associated member recreational vehicle manufactures of this! Our 2011 32ft motorhome is pretty standardly equipped with a 15,000btu HVAC pulling 14 amps (running amps not startup), 6 gallon electric water heater pulling 10 amps (when heating), microwave pulling about 8 amps, DC converter pulling 1-7 amps, fridge pulling 5 amps. Sure not all of those loads run continuously, but you can bet for at least the first couple hours of pulling into a campsite they are on. In Texas your HVAC runs 100% in the summer during the day and so does your fridge, that's 19-20 amps right off the top.
To summarize in all my 18 years of camping in the Texas heat with only a lonely TT-30 outlet for days on end where these are abused public use outlets have I never had to think about how much of a max load I am putting on the wiring and\or plug nor do I suppose does another typical weekend warrior camper whos like myself.
When such an emergency does occur when I find myself needing to plug in to a TT-30 at the max setting the 6.6Kwh leaf charger can take (27.5 amps @ 120 or 240 volts) at a charging rate of only about 12 miles per hour it won't be an issue. Why, because who in their right mind would sit around a campground charging at a rate of only 12 miles per hour for any longer than needed to get them to a DC charger or 6.6Kwh L2 charger?
Over the past couple of years, NY has gradually been adding TT-30 outlets to all of the campsites in the state parks. The downside is that I now have to share campgrounds with more RVs than ever before (and for whatever reason, RV "campers" are incredibly rude and inconsiderate to tent campers, but that's another issue). The upside is that I can charge my EV while I camp.
As much as I have tried, the Bolt EV simply does not accept more than 12A on a 120V circuit. If I could get 24A from that TT-30, it would double my charging speed, allowing more side trips during the days.
Is the above also true with a Leaf? I never tried more than 12A when I had a Leaf. Can a 2020 Leaf, for example, charge at 24A / 120V? Asking more for a friend than myself. He has a 2019 40kWh Leaf, so less range than my Bolt. If he could charge faster while we camped, that could make up the difference.
