Third Product Questions
Why is my Supercharger charging slowly?
There are a few factors that affect charging rate at a Supercharger. First, charging your battery from 10% to 80% is quick while charging from 80% to 100% doubles the charge time because the car must reduce current to “top off.” Second, extremely low ambient temperatures and extreme battery pack temperatures lead to slower charging rates. Third, sharing a Supercharger (i.e. two cars plugged in to 1A and 1B) can slightly reduce the charging rate of one or both of the cars.

How fast can I charge?
Charging rate is primarily determined by what you’re plugged in to. A Tesla Supercharger charges up to 170 miles in just 30 minutes while the Tesla Wall Connector charges up to 58 miles per hour. For average charging rates of other options, check out the charging page on tesla.com.
There are several other factors that affect charging rate: amount of power available from the charge source, extremely cold temperatures, and current state of charge (a nearly empty battery charges faster than a battery that is almost full).
