800-mile road trip with a Mach-E — do I actually need a portable EVSE as backup or am I overpacking?
My wife and I are driving from Nashville to Denver to see her sister, three days, first trip anywhere close to this long since I got the Mach-E last year. Route's mapped in ABRP with six stops split between Electrify America and Supercharger via the NACS adapter, overnight in Springfield, Missouri the first night and Salina, Kansas the second. When we started planning I guessed it'd be around 800 miles total, turns out ABRP has us just over 1,000 once you account for the actual highway routing, which was its own small surprise.
I mentioned I was also picking up a portable EVSE to bring along just in case, and my wife looked at me like I was overpacking for a trip that's already fully mapped out stop by stop. So, genuinely asking the people who've done this more than me — is a portable charger actually smart backup for a trip like this, or is it one of those things we all buy because Reddit talks us into range anxiety when the actual infrastructure along a route like this is fine these days?

Bring it. I live at the Denver end of routes like this and I can tell you the stretch through western Kansas and into Colorado on I-70 is fine on paper but thin in practice — you're often looking at one plaza per exit with 4-8 stalls, and if even one is down or a line forms behind a slow charger, your buffer disappears fast. A portable EVSE doesn't replace DC fast charging, but it means a bad stop turns into 'find any outlet and add 20 miles overnight' instead of 'stranded.' I've used mine exactly twice in three years of road trips, both times it saved the day. Two years of basically nothing until the one day it matters is exactly what backup gear is for.

I've had three separate charger failures on trips this year, so I'm generally the person telling everyone infrastructure isn't as solid as it looks on an app. That said, a portable EVSE wouldn't have fixed any of the three — one was a whole plaza down for maintenance, one was a broken card reader with a full parking lot behind it, one was a stall that just errored out every time. In all three cases the fix was driving to the next plaza, not plugging into a wall somewhere. I think the portable charger solves a different problem than the one people usually road-trip-panic about.
Disagree a little here — I carry one in the Lightning specifically for the scenario where I'm not near any plaza at all, like an overnight stop at an in-laws' place or a hotel with no charger listed. It's not there to fix a broken Supercharger stall, it's there for the gap between planned stops where there's no charging infrastructure at all, just outlets. Different tool for a different failure mode, but still a real one on a three-day trip.
That's fair, I was thinking about it purely as an EA/Supercharger insurance policy which it isn't. As an overnight-stop insurance policy it makes a lot more sense, and yeah, a three-day trip means two overnight stops where OP has zero idea what's actually available at the hotel.

Practical note on the gear itself — most portable EVSEs worth bringing come with at least a 5-15 (regular outlet) adapter and ideally a 14-50 (like a dryer or RV outlet) adapter too, since the 14-50 is what gets you real overnight recovery, 30+ miles an hour on a Mach-E versus 3-4 on a standard outlet. Don't just throw the unit in the trunk, check which adapters actually came with it and buy the 14-50 one separately if it didn't, it's usually the missing piece people find out about at the worst time.
Good call, I actually only have the 5-15 adapter that came in the box. Didn't realize the 14-50 was sold separately for mine, going to go check that before we leave.
Worth the roughly $30-40 it usually runs. Even if you never plug into a 14-50 the whole trip, having the option changes what an overnight stop at a random hotel or relative's house can actually do for you.

We keep one in the Mach-E permanently at this point, not even trip-specific anymore, same logic as everyone above — it's for the stop that isn't on any map, not the stop that's supposed to work but doesn't. Small enough it just lives in the frunk and we forget it's there until we need it.

Counterpoint just so it's represented here — I've done two out-of-state trips without carrying one and been fine both times, purely relying on the planned network stops. I know that's not a guarantee and I got a little lucky, but it is possible to do this without the backup gear if your route genuinely has good coverage and you're not doing overnight stops somewhere without charging.

packing one for our trip too now
