Understanding EV Charging Levels: What Makes a Charger Fast?
According to the US Department of Transportation, there are three main types of EV charging, but for home use, Level 2 chargers provide the optimal balance of speed and practicality.
Level 1
120V / 12-16A
4-5 miles/hour
Level 2
240V / 16-80A
10-75 miles/hour
Level 3 (DC Fast)
400-800V
180-240 miles/hour
"Level 2 charging is the sweet spot for home installations. Research shows that 80% of EV owners do their primary charging at home, and a 19.2kW Level 2 charger can fully charge most EVs overnight while being significantly more cost-effective than DC fast charging." - Electric Vehicle Infrastructure Association, 2025
Pro Tip: While DC fast charging is faster, it's not practical for home use due to cost (up to $1 million per mile of cable installation) and electrical requirements. Level 2 charging offers the fastest practical home charging solution.
