## My answer

The site has a calculator for this. Charging at 2.4 kW through Schuko may already cover your usage overnight, including a 20–70% charging window in some circumstances.

Use the [home charging calculator](https://usateslata.com/en/tools/home-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).

As of 2026-11-04

First check the contracted capacity, circuit breaker, cable cross-section to the garage and spare capacity in the building’s electrical installation. If you need more than the contracted capacity, apply to the relevant distribution operator. Changing from single-phase to three-phase supply is a separate procedure. Work on shared parts of an apartment building may also need technical coordination and consent.

**2.4 kW × 8 hours = 19.2 kWh from the socket**, before charging losses. That may cover a small or moderate daily distance, but it does not guarantee a 20–70% charge overnight. Battery capacity, temperature and starting charge matter.

A Schuko socket should be used for sustained charging **only after a qualified electrician checks its suitability, grounding and protection**. Do not assume every socket can safely deliver 2.4–3 kW for hours. Avoid coiled cable reels and unsuitable extension leads.
