Portable EVSE Amps over 110v/120v

[FlasherZ]

Its frowned upon for multiple reasons, but mainly the wrong gauge wire is used for a particular application. For myself, I need to find a middle ground so I can charge this beast.

The code addresses cord ampacity, that's not so much of the issue as it's the fact cords get beat up and are subject to damage, which creates higher resistance and heat, plugs pull apart, etc. Then there are the reasons - they get tripped over, doors get slammed on them, etc.

Nonetheless, frowned upon.

I have used an appropriate guage extension cord on occasion. Usually if I can't park right next to an outlet at a hotel. It was for a phev, so no more than 7kwh over 6-8 hours going through the cord. Still not recommended, but it can work.

I'm at a campground with 120v 30 amp hookups with a TT-30r. I have an EV specific TT-30 to 14-50 adapter and a j+ booster set to 24 amps. The truck is only pulling 1.2kw... is this a vehicle setting limiting the charging on 120v to 10-12 amps total? Anyone know if it can be changed to let me do 24 amps?

no, not with the Ford supplied charger, and I don't think ANY evse equipment let's you adjust 120v power, only 240v power. I wish it did, but otherwise you are going to stay at 12amp regardless of what 'size' 120v outlet you use, even a campground 30amp.

You didn't read my post correctly, I bought a portable charger that lets you adjust the amperage. I set it to 24 amps but the truck is still only drawing 1.18kw total, so 10 amps.

This is what I bought:

@wighty Another poster said they had an EVSE that did supply 24a on a TT-30 to the truck... I am hoping to do the same. EDIT:

J+ Booster is a nice looking EVSE. Odd/surprising its not working.

Yeah I was using that thread for info originally. I'll have to try and contact the manufacturer next week. They don't have the TT-30 adapter available yet so I had to do the workaround with the TT-30p to 14-50r. Shouldve gone with the charger that was confirmed to work I have a DCFC like 15 miles from me on the way home so at least I am not stranded.

Curious, are you able to put a tester on your hookup to verify the V & A output available?

I meant to bring a multimeter, but no I can't specifically verify except that the class A RV next to me says he was getting at least 16 amps at the time I asked him (which was just the load he was drawing, not the max that he tested).

You really can’t compare power used by an RV with charging.
Either the EVSE or the in-vehicle charger can throttle the current for any number of reasons. For the RV, the loads are static and there is no throttling capability. If he plugged in enough stuff, he could draw 50A on the 30A circuit. For a couple minutes, anyway.

Okay... My point is that the outlet was at least providing 16 amps, as the other person was probably alluding to is the outlet even providing up to 30 amps as rated.

My first EV charger I bought on Craigslist was a Duosida L1/L2 dual voltage EV charger that draws 16A (NEMA 5-20p) on 120V.

I used this on my first EV and it charged at 1.5kWh which was sufficient for the small battery it had.
Perfect for overnight charging.

I just tested this on my Lightning and it was about 1.7kWh rate.

Just that most people (residential) do not have the 5-20 receptacle, but with a pigtail adapter to

5-15 it still works without tripping the breaker.

The Duosida is now in my frunk for emergencies.

All outlets provide the current demanded by the load. There is no way for an outlet to limit the current (until the breaker trips).

You aren't telling me anything I don't know. I am thinking that the truck is doing the limitation here as it is detecting 120v and thinking it doesn't want to overload a potential 15 amp circuit (edit: as others said it sounds like other chargers are working over 10 amps, so as below I'll ask the EVSE manufacturer). The EVSE is set to 24 amps and is not giving any errors. I'm going to ask the manufacturer next week to confirm that it, which again would mean that the truck is limiting itself. The last few posts were asking to rule out the outlet as not working correctly (understandable that if the circuits were all overloaded nothing would work at all because breakers would trip... But that is assuming the park correctly has everything wired, right?).

I dont know which is more dangerous. That adaptor or the one that will defeat the ground.
