120V 12 amps

120V 12 amps

Says I'm getting 0/mph charge.

Is that normal?

20 degrees outside but it's been an hour plugged in.

What are the indicator lights on the charge adapter and charging port doing ?
Has you phone been notified of charge starting or stopping ?

Mike UpNorth | 17. November 2018

All indications show it's charging.
It actually just changed on the app. Now it says 1 mph charge. After 90 minutes.
I guess it took a very long time to warm the battery. Probably still is warming.

Super dumb question....my Tesla didn't come with an adapter for 220v right?

It's heating the battery preferentially.
Car came with a 14-50 adapter for 240V outlet.

@michael, the mobile charging unit should have come with a NEMA 14-50 plug, which is for 220.

gmr6415 | 17. November 2018

That should have been 240v 50 amp.

The car cannot charge with such low temperatures. The charger needs to heat up the battery before charging. 120V 15 Amps is not enough power to charge and heat up the battery simultaneously... install a 50 Amps 240 Amps outlet or move the car to a warmer place...

As other threads have mentioned, if it's cold out you might not get much charge off of 120 volts at 12 amps. Nearly all the power is being used for heating. I think 0 mph charge rate after an hour under those conditions is expected. If you want to add miles, find level 2 or better charging somewhere.

Sorry guys, I wasn't using the correct terminology. Forget what I said. Yes, it came with 14-50. I guess there's a different type of outlet that looks weird and is only 220v but much lower amps.

After 90+ minutes plugged in I got to 3 mph charge. I then moved to an outlet right next to the box and now I'm getting 5 mph charge. Moral of story in the cold and low amps takes almost 2 hours to start getting a charge. And also try and plug in close to the box.

Thanks for all your help.

@Michael. If you have access to a 120v-20amp receptacle, the adapter is well worth the money. That is assuming you don't have access to 220v.

michael -
There are a plethora of outlet types, especially for 240V. Look here:
https://en.wikipedia.org/wiki/NEMA_connector
and figure out which one you have - the 10-30, 14-30, and 14-50 are common. You can then order the correct adapter for your UMC at:

Good info, thank you.

Defininitely you should upgrade to a 220v circuit and preferably 60A breakers for the cold weather. You want to heat and charge as fast as possible in these cold conditions.

>>> You want to heat and charge as fast as possible in these cold conditions.
Why?

Otherwise you are spending a significant portion of the energy on heating the outside world rather than charging the battery.

Maybe the grid is sucking power from your car.

@Kikujiro- ha!
