If you're familiar with Oregon geography, I was going east from the Willamette valley up and over the Cascades. Pretty close to starting the climb up to the pass the road was closed "indefinitely" due to an accident. I had to backtrack all the way to the valley, then south on I-5 to the next highway going over the pass, taking the longer route to the destination. It "probably" would have required a recharge in an EV. In my case there was enough gas left, but even having to stop for gas is a whole lot less hassle than recharging.
If you're talking about highway 20, there are a ton of Tesla chargers in Detroit, and then again in Sisters, so needing a charge on either side is not an issue. Heading back down, an EV will use hardly any energy since you're mostly coasting and regenerating. I'll have to pay attention to see what my battery percentage is at the top of the pass compared to when I get home, but I bet I only use 10%. I'm not familiar with the charging infrastructure going through Sandy, or highway 58. I'm sure those routes have good charging infrastructure as well.
I've made a few longer trips in the Tesla, and it charges fast enough to not be a nuisance. I can make it from Silverton to a friend's house in Redmond AND back without stopping to charge (270 miles).
Took a trip to Redding (400 miles) and stopped to charge once on the way down. In the time it took to walk to Muchas Gracias, use the restroom, and walk back to the car, I had way more charge than needed to complete the trip. Charged just once on the way back, and only needed maybe 10 minutes. You'll spend that much time getting fast food and using the restroom.
The neat thing about Tesla charging is you just connect the cable and it starts charging. You can also set a charge limit so you're not paying for more than you need/want.
Finally, in most energy markets, electricity is about 1/3rd the cost per mile compared with gasoline for a comparable vehicle.
Well guess what we got for Christmas, now last year, from our family, a battery station invertor, lol. Our only issue with outages was trying to save the food in our freezer/refrigs. But again, $1,000 portable generator to save $300 in food? As you can tell I am kinda frugal. After telling our kids, many times, how we empty our freezer/frigs into coolers with ice they said we needed a generator
I don't have any use for those portable battery/inverters and they are mostly gimmicky, though plenty of people run a CPAP while camping. The problem is it's a combined solution. What are the odds the battery is exactly the capacity needed, combined with an inverter with exactly the power rating needed? Then the thing becomes garbage when either the battery or inverter dies. Better to spec out the battery and inverter separately.
The real problem is that a battery barely holds any energy compared to gasoline. There's no battery/inverter combo that would have run our house for the week we were without power a few years back. Fortunately my dad had an extra $200 gasoline generator. It ran half the circuits in my house, and the fridges at both my neighbors houses (long extension cords). I had lights, TV, forced air furnace, microwave, washer, dryer... you name it. It worked out for me because all my heating is natural gas, so no 240v circuits were needed.
I've got an even better solution now that I own a plug-in hybrid vehicle (PHEV). Next time there's an outage, I'll connect an inverter directly to the 12v battery, which is maintained by the DC/DC converter and larger traction battery. If that battery runs low, the engine will come on and charge it. A PHEV is essentially a portable generator.
