How Many Amps Do I Need for an EV Charger?
Quick answer: Many homes land in the 32A to 48A range, but the best answer depends on panel capacity, breaker space, and charging goals.
You do not start by buying the highest-amperage charger. Start with the vehicle, daily miles, panel capacity, and what your electrician says is realistic.

Frequently asked questions
Do I need a hardwired charger?
Not always. Plug-in chargers can work well, but hardwired setups often make sense for higher amperage or cleaner permanent installs.
Can a 100 amp panel still support home charging?
Sometimes yes. The key question is not the panel label alone, but how much spare capacity exists after the home's existing loads are considered.
Why use a local installer page instead of just buying a charger?
Because charger selection and installation complexity are connected. Local quote pages help turn product research into a realistic home setup.
