Frequently Asked Questions
How many watts does an electric car charger use?
The power consumption of an electric car charger is typically measured in kilowatts (kW) rather than watts (W). However, to give you a rough estimate, a Level 1 charger uses around 1.4-2.3 kW, which is equivalent to 4,800-9,600 watts. A Level 2 charger uses around 3.3-7.2 kW, which is equivalent to 11,280-24,960 watts. A DC Fast Charger uses around 50-100 kW, which is equivalent to 176,000-352,000 watts.
What is the difference between Level 1 and Level 2 chargers?
Level 1 chargers use a standard 120-volt household outlet and have a power consumption rate of 1.4-2.3 kW. Level 2 chargers use a 240-volt outlet and have a power consumption rate of 3.3-7.2 kW. Level 2 chargers are faster and more efficient than Level 1 chargers. (See Also: How Much Water to Put out Electric Car Fire? Safety Tips Included)
