ENERGY STAR certified EVSE
ENERGY STAR certification for EV chargers (EVSE) verifies low energy waste when the charger is idle — certified units draw dramatically less standby power, saving roughly $25+ per year, and the EPA publishes their tested specs in a public dataset.
Chargers spend over 80% of their life not charging, so standby draw matters more than it sounds. Certification testing measures no-vehicle, partial-on, and idle modes against strict allowances.
Some utility rebate programs require ENERGY STAR certification, and this site’s entire charger catalog is built from the official certified list.
