How many miles will a power wall charge a Model S?

[wayneone]

If you have a completely depleted Model S, how far can you get with a single power wall charge? (without grid or solar connections)

Based on some quick maths, somewhere between 10 and 21 miles?

Depends on how many modules you've installed and which kind of Powerwall.

OP said a "single power wall charge". So either the 10kWh or the 7kWH version.
Answer to the OP: not very far. You are in the ballpark. Obviously depends on driving speed, weather conditions, etc.

Let's say you can get 7 kWh from the Powerwall. Subtract 20% in losses at the inverter and chargers and battery = 18 miles.
