Sufficient for what?
If you only drive to destinations less than 200 miles away, you might be okay, but I suspect you can’t make it to Lake Tahoe due to the elevation gain. You need about 20 kWh more, easy to add at a DC fast charger along the way, over three hours to add with Level-2.
In eight months many more chargers will be open, especially Electrify America but others too.
