Charging on a trip

Charging on a trip

I had a 14-50 plug installed in my garage along with a hose hanger to hang my charger wire. Left my adaptors in the car. I charge at home every few days.
In what situation might I need to have the cord with me when I’m traveling and expect to charge elsewhere?

North Dakota or an error in judgment at a supercharger

Or charging at a friend’s

I haven’t ventured out to a Supercharger yet. Will I need it there?

You neither need need your mobile connector nor any adaptors to charge at a supercharger.

I recommend you keep your J-1772 adaptor in your car since you will need that to charge at many charging stations (including ChargePoint, etc.).

I also recommend you plug your car in whenever it is in your garage.

No—the only time I use it, and I travel extensively, is at friends’ houses to save time to allow for longer visits.

I have a 14-50 outlet at home and use the UMC. When I travel I pack the UMC “just in case”.

Most people buy a separate UMC to avoid plugging and unplugging to the 14-50, as they can go bad in as few as 50 connections/disconnection. But a new 14-50 is about $10 or twice that for a heavy duty.

@msmith55 please elaborate :"as they can go bad in as few as 50 connections/disconnection".

I unplug the supplied charger from 14-50 plug once finish charging, I assume it will damage the transformer(?, the big bulky thing near the plug) if it was keep plugging in..

To answer the OPs question... When you get off the beaten path and need to charge at an RV park or campground with RV hook-ups. They most often will be a NEMA 14-50 outlet so you charge with the UMC and the NEMA 14-50 adapter: https://s3.amazonaws.com/plugshare.production.photos/photos/77258.jpg The picture is from Gouldings Campground at Monument Valley, UT.

Deezeela, leave your UMC plugged into the outlet. It will not harm it at all. Mine stays plugged in except when I take it with me for the annual service. Been do that fro over 4 years now.

I also purchased the UMC adapters for the most common dryer plugs and made a 30 amp 30 foot extension cord that I carry with me on trips. On my first trip it came in handy. The people we were staying with had a laundry room next to their garage. I could park in the garage and between the 20 foot UMC cord and the 30 foot extension I made I had about 5 feet to spare after hooking up to their dryer plug.

In 4 .5 years of driving Model S (just traded in to M3) I have never had to use my Mobile connector anywhere except for home.

Buy an extra set to keep in the car for flexibility and peace of mind. Mine came in handy when I rented a mountain cabin. It had a 110v exterior outlet that topped up the battery,

I plan to travel all over, I'd humbly disagree...order some of the extra plugs you think you might need. I plan to be in places where Superchargers aren't available and want to make sure of a smooth charging experience.

Better safe than sorry.....I made a trip from FL to MA and brought my cord, as well as a 20' NEMA extension cord. They take up very little room. Never needed either, but I had a little peace of mind.

I was playing with my mobile connector to be sure I knew how to use it for my first long trip--PA to Florida. Apparently I do not. I plugged in one of the adaptors and now cannot unplug it. If the manual addresses this, I could not decipher it. Any thoughts?
