Hello all, I've been reading older threads here where people are strongly discouraged from running extension cords on 240V outlets for regular charging, and I completely understand why. I'm in a spot where I may have to do it, but only a few times, so I'd like to hear whether it can be done safely.
Context: we're taking our Ioniq 9 (NACS port) on a road trip that ends at a fairly remote island with little to no charging infrastructure nearby. We'll charge fully before the final leg, but that leg is still several hours of highway driving. The house we're staying at has no dedicated charging equipment. It does have a dryer in a basement room (a beach house laundry room) close to where we'd park. So the plan would be to use the dryer outlet with a short extension cord to cover the distance, probably 15-20 feet.
We'd only need to charge once or twice during the whole stay, just enough to easily make it to Level 3 charging on the way back. We have the Ampure 2 portable charger that came with the car.
I've also been reading a thread where someone built a single-cord setup with adapters for different outlet types (10-30, 14-30 and so on), and it got me thinking about the same questions for my situation: what the right cord gauge and rating is for a run that short, and what amperage I should set the car to.
With all that in mind:
1. Is it possible to do this safely for a couple of charging sessions?
2. What equipment would you recommend for the cord and any adapter between the dryer outlet and the Ampure 2?
3. Should I limit the current in the car, and by how much?
4. Is there anything I should check at the outlet itself, like whether it's a 10-30 or 14-30, the condition of the receptacle, or how warm things get, before and during charging?
Thanks in advance. I'd rather ask now than improvise once we're out there.
