KEY FEATURES:

Calculate exact charging session costs based on your specific battery capacity, charging efficiency factor (wall-to-battery losses), and peak or off-peak utility electricity rates.

• FAIR UTILITY BILL SPLITTING
Split household energy costs with precision. FairWatt calculates and isolates EV power consumption from general household electricity, making roomie reimbursements fast, clear, and fair.

• EXPORT & SHARE RECEIPT CARDS
