EV Charger Check

Disclosure: Manufacturer links on this site are plain links, not affiliate links yet. If that changes we may earn a commission at no cost to you, and this notice will say so. We have not tested any charger. Specs come from ENERGY STAR certification data and EPA/DOE fuel economy data; charging-time, range-per-hour and cost figures are estimates. Not electrical advice: have a licensed electrician size and install your circuit. Learn more.

Estimates. Power = charger current × voltage (or the charger's listed kW at 240 V), capped by the car limit you enter. Energy needed = EPA kWh/100 mi × EPA range ÷ 100 × (to − from)%, which is measured at the wall and already includes typical charging losses. Charging slows above ~80% and in the cold. Vehicle data: fueleconomy.gov; charger data: ENERGY STAR (2026-10-17); rates: EIA July 2026 (preliminary).
