Owning an electric vehicle in Hawaii is all about freedom — freedom to explore the island, save on gas, and lower your impact. With a professionally installed home EV charger, you can wake up every morning to a fully charged ride, ready for the road.

At Ultimate Electrical in Kailua Kona, we specialize in safe, reliable Level 2 EV charger installation for homeowners across the Big Island. A Level 2 charger connects to a dedicated 240-volt circuit, charging your EV up to 8x faster than a standard outlet — which means most vehicles are fully charged overnight when rates are lowest.

Plus, you may qualify for local utility rebates and federal incentives that can cut installation costs nearly in half.

FAQs About EV Home Charging

The cost depends on the charger, your home’s electrical panel, and available rebates. We’ll provide a clear estimate before any work begins and help you find local and federal incentives.
Most homes will need at least 150-amp service, but we recommend 200-amp service for maximum capacity and safety. If you’re on 100-amp service or less, an upgrade is usually necessary.
Level 1 chargers plug into a standard outlet, but Level 2 chargers require professional installation with a dedicated 240-volt circuit. For safety, warranty protection, and insurance coverage, always hire a licensed electrician.
  • Level 1 (standard outlet): 20–40+ hours for a full charge
  • Level 2 (dedicated circuit): 4–10 hours — perfect for overnight charging
