Yes. If you have either an EV with adjustable charging amperage (such as any Tesla model) or an adjustable EVSE, you have the ability to manually set the charging amperages to your liking when using a 50A Smart Splitter. Note: the Smart Splitter itself cannot adjust the charging amperage. Due to NEC regulations, you are only allowed to charge at 80% of the breaker's rating, so that means you have 40A at your disposal to charge your cars. For simultaneous charging, most Smart Splitter users will set both cars to charge equally at 20A each, but you can also manually allocate the power draw by setting the charge rates to 24A and 16A, or any other configuration of your choosing..
