Please, I'm looking for knowledge, not guesses.
I'm planning a trip in a couple of weeks to a friend's cabin, and I'm wanting to know what happens in "worst case scenario".
First off, I can't make it from the nearest charger (Tesla or other public) and back again. Just not possible. So I have to charge on site. That *shouldn't* be an issue, but this is a cabin and I'm not sure the power situation is reliable. Also, there's been a ton of snow and it hasn't been cleared from the long, unpaved driveway so now they're telling me I may have to park down at the main road until it gets cleared (if it does).
So I'm looking at the distinct, but hopefully small, chance that I can't charge. In that worst case scenario... it has been suggested that I can use their portable generator to charge it enough to get back to a real charger. It is a Firman 3550 generator. Looking that up, I see it is rated for 3500W continuous (4550W surge) and has a 20A outlet, which I think the Tesla would pull 12A off of (12 * 120 = 1440W, so well under rated capacity @ 50). So it *sounds* like it would work...
But "should" work and "does" work are two different things. I once tried charging at my Grandmother's house by way of an extension cord... and the Tesla wouldn't charge at all. I don't mean "slow", I mean not at all. We plugged a lamp into the cable and it worked, so my assumption was that the Tesla has circuitry that determines if the power coming in is high enough and/or stable enough and it won't allow it if it doesn't pass the test. Generators are fairly notorious for putting out "dirty" power.
Anyway... should I cancel the trip? Or I'll be OK if I have to use a generator in a pinch.
Thanks.
