## My answer

Without a conversion to the European standard, charging is around 7.4 kW. Single-phase supply is normal in the USA. This mainly matters when charging at home. If you usually charge overnight, it need not be a problem; a DC station is an option when you need faster charging.

I have collected the details and sources in [the full article with 13 questions about a US Tesla](https://usateslata.com/en/updates/tesla-ot-sasht-v-bulgaria-vaprosi-otgovori-zarezhdane-garantsia-farove#charging).

## AI assessment

As of 2026-11-04

North American Model 3/Y cars use single-phase AC charging through their North American port. **Single-phase does not mean every car has a 7.4 kW maximum.** Tesla lists onboard charger configurations rated at 32 A, about 7.7 kW at 240 V, or up to 48 A, 11.5 kW at 240 V. Actual charging in Bulgaria also depends on voltage, the adapter, the station and the vehicle’s limits. At 230 V and 32 A, approximately 7.4 kW is a useful reference.

A Type 2-to-NACS adapter **does not turn a single-phase onboard charger into a three-phase charger**. An 11 or 22 kW European station cannot make the car use power its hardware does not support.
