Charge Your Vehicle Overnight at Full Speed

Level 2 EV charger installation for homes in Johnston, Iowa

Your electric vehicle needs to charge overnight so it is ready to drive the next morning. A standard household outlet charges too slowly, often taking more than twenty hours to fully charge a depleted battery. A Level 2 EV charger delivers power at a much higher rate, allowing your vehicle to reach full charge in four to eight hours depending on the battery size and charger capacity.

Jenson Electric, LLC. installs Level 2 EV chargers for homeowners in Johnston who need fast, reliable charging at home. The charger is mounted in your garage or on an exterior wall near your parking area. A dedicated circuit is run from your electrical panel to the charger, and the system is tested to confirm it delivers the correct voltage and amperage. Installation includes proper load sizing to ensure your panel can support the charger without overloading other circuits. If your panel is undersized, it may need to be upgraded before the charger is installed.

How the Charger Is Wired and What It Does

When you schedule EV charger installation in Johnston, the electrician evaluates your electrical panel to confirm it has enough capacity and an open slot for a new circuit. A dedicated 240-volt circuit is wired from the panel to the charger location, and the charger is mounted securely to the wall or post. The circuit is protected by a breaker sized to match the charger's power rating, and the system is tested under load to confirm proper operation.

After installation, you notice that your vehicle charges much faster than it did on a standard outlet. You plug in when you arrive home, and the battery reaches full charge by morning. The charger provides consistent power regardless of weather, and most models include scheduling features that allow you to charge during off-peak hours when electricity rates are lower. If your home has a backup generator, the charger continues operating during outages as long as the generator is sized to support it.

The installation includes permit coordination when required, final inspection scheduling, and a walkthrough to explain how the charger operates. Chargers are installed to meet Iowa electrical code and manufacturer specifications. Jenson Electric, LLC. also upgrades panels when needed to support the additional load.

You Probably Want to Know These Things First

Homeowners in Johnston often ask similar questions about EV charger installation before scheduling the work. The answers below cover what to expect and what your home needs to support a Level 2 charger.

What is the difference between Level 1 and Level 2 EV chargers?
Level 1 chargers plug into a standard 120-volt outlet and charge very slowly, often taking more than a day to fully charge a vehicle. Level 2 chargers use a 240-volt circuit and charge much faster, typically completing a full charge in four to eight hours.
How much does it cost to run an EV charger?
Costs depend on your electricity rate and how often you charge. Most homeowners in Johnston pay between thirty and sixty dollars per month to charge an electric vehicle at home, which is significantly less than the cost of gasoline.
Why do some homes need a panel upgrade before installing an EV charger?
EV chargers draw a significant amount of power, often 40 to 50 amps. If your panel is already near capacity or does not have an open slot for a new circuit, it must be upgraded before the charger can be installed safely.
What happens if I want to move the charger later?
Chargers can be relocated, but the dedicated circuit must be extended or rerouted to reach the new location. If you move to a new home, most chargers can be uninstalled and reinstalled at your new property.
When should I install an EV charger before buying an electric vehicle?
Installing the charger before your vehicle arrives ensures you can start charging immediately. Most installations take one day to complete, but scheduling and permit approval can add a few weeks depending on local requirements.
