You bought an EV and realized the 120V wall outlet in your garage is going to take 40 hours to charge your car. Level 2 charging (240V, same type of outlet as a dryer) is the standard home setup - most people get from near-empty to full overnight.
Installation is an electrical job, not a general handyman job. The charger itself costs $300-$800. Installation varies based on how far the panel is from the garage, whether your panel has capacity, and whether you need a panel upgrade. In Bethesda and Chevy Chase where houses are older, panel capacity is often the surprise cost - budget for the possibility.
Federal tax credits cover 30% of the installation cost. Ask your electrician if they're familiar with EV charger permits in your jurisdiction - some require inspections. Red flag: anyone who says you don't need a permit (you almost certainly do), or who installs a Level 1 outlet and calls it a Level 2 charger.
