How to Choose the Right EV Charger for Your Home


Electric vehicles are more popular than ever—and if you own one or are thinking about buying one, the next step is figuring out how to charge it at home. That’s where an EV home charger comes in.


At Oliver Electric, we often get asked:

“What kind of EV charger should I install at my house?”

It’s a great question—and the right answer depends on a few key things like your car, your electrical panel, and your daily driving habits.


Let’s walk through the basics so you can make a smart, safe choice.


The Two Main Types of EV Chargers


There are two common types of EV chargers used at home:


Level 1 Charger

 (Standard Outlet)


  • Plugs into a regular 120V wall outlet
  • Adds about 3–5 miles of range per hour
  • No extra installation needed
  • Best for occasional drivers or plug-in hybrids


This option works for overnight charging, but it’s very slow—sometimes taking over 24 hours to fully charge a battery.



Level 2 Charger

 (240V Installation)



A Level 2 charger is what most EV owners choose. It’s fast, reliable, and can be installed in your garage, carport, or driveway setup.


What to Consider Before Installing


Before picking your charger, here are a few important things to think about:

1.Your Driving Routine


If you drive long distances every day or use your EV as your main car, a Level 2 charger is probably the best fit. You’ll save time and avoid range anxiety.



2.Your Home’s Electrical Panel


A licensed electrician will check if your current panel can handle the extra load. If it’s an older home, you might also need a panel upgrade to safely add a 240V circuit.


At Oliver Electric, we’ll evaluate your system and let you know exactly what’s needed—no guesswork, no surprises.



3.The Location of the Charger


Where will your EV be parked?

We install EV chargers in garages, carports, and even on outdoor walls. We also make sure the wiring is weather-safe, secure, and ready for long-term use.


Can I Install an EV Charger Myself?


In short—no, and here’s why.


EV chargers deal with high voltage and must follow electrical code compliance. Mistakes during installation could damage your vehicle, cause a fire hazard, or void your car’s warranty.


That’s why you should always hire a licensed electrician near me to handle the install. At Oliver Electric, we’ve installed dozens of home EV charging stations safely and quickly. We handle permits, inspections, and everything in between.


Should I Install a Smart Charger?


Many modern chargers are “smart,” which means they can:


  • Track energy use
  • Set charging times (like off-peak hours)
  • Connect to apps for control and notifications
  • Work with smart home systems


If you’re already using or planning a smart home system, we can integrate your EV charger so it’s part of your home’s connected network.


What If I Need a Panel Upgrade?


It’s not unusual for older homes to need an electrical panel upgrade before a Level 2 charger can be installed. Don’t worry—we specialize in both.


We’ll inspect your current setup, recommend the right size upgrade (usually 200 amps), and make sure everything is done to code. After that, we’ll install your EV charger quickly so you can start charging without delay.

One of the worst calls I've responded to was a panel hot to the touch and smelling like burning plastic — the homeowner had been resetting the tripping breaker for three days, thinking that was the fix. By the time I arrived, there was heat damage inside the panel. They were minutes away from a house fire. That single mistake — keep resetting instead of calling — is more common than most people realize, and it's exactly the kind of situation emergency electrical services exist to stop before it becomes a disaster. Warning Signs You Need Emergency Electrical Services Right Now Most homeowners miss the small signs because they seem normal — until they aren't. Here are nine warning signs that represent active danger inside your walls and panels: Lights flickering often Outlets or switches warm to the touch Buzzing, crackling, or sizzling sounds Brown or black marks around outlets An outlet that stops working and comes back on its own A small shock when touching a switch or appliance Breakers tripping more than once A burning plastic smell Power going in and out in one room Each of these signals something wrong you cannot see without proper testing. Heat, arcing, and failing connections happen inside walls and panels — and they don't announce themselves loudly until something goes seriously wrong. If you live in a hot climate, pay extra attention. Garages, attics, and outdoor electrical panels take a beating in summer heat, which accelerates wear on connections and makes weak spots fail faster. If something smells hot, sounds wrong, or keeps repeating, don't ignore it. The U.S. Fire Administration reports that electrical fires cause over 24,000 home fires annually — most of them preventable. Warm outlets deserve a closer look than most people give them, because not every warm plate is an emergency, and knowing the difference can save you a panicked midnight call, or push you to make one when it truly matters. A dimmer that runs a little warm is normal. An outlet that is hot, buzzing, or warm with nothing plugged in is not. I break down the causes, my warm-versus-hot rule of thumb, and typical repair costs in my guide on why your outlets feel warm to the touch Emergency or Can It Wait? How to Make the Right Call I look at risk first. Here is the decision framework I give every caller. Call immediately if you have any of these: Heat or smoke from an outlet, panel, or appliance Sparks or visible arcing A burning smell near any electrical component Buzzing coming from the panel Breakers that keep tripping Water near electrical components Loss of power to critical equipment It may be able to wait if: A single outlet stopped working with no heat, smell, or buzzing The issue is purely inconvenient and nothing feels or smells wrong The simple rule I tell people: if the issue can cause fire, shock, or equipment damage, call now. If it's just an inconvenience and everything is safe, schedule normal service. When in doubt, call and describe what's happening. A good electrician can help you decide whether it needs immediate attention — and that call costs you nothing. The Mistake That Turns a Small Problem Into a Dangerous One I had a call where a homeowner lost power to part of the house. Instead of calling, they bought a breaker at the hardware store and swapped it themselves. The problem wasn't the breaker. The real problem was a loose connection creating heat on that circuit. When they installed the new breaker, it kept feeding power straight to that bad connection. By the time I opened the panel and traced it, part of the wire insulation was damaged. What could have been a smaller repair turned into a much bigger job. DIY electrical work gets dangerous fast during emergencies because you can only see the symptom — not the cause. Fixing the wrong thing can keep power flowing to a failing connection, which is worse than the original problem. Tripping breakers, power loss, buzzing outlets, and burning smells are diagnostic signals that require someone trained to test the full system. The National Electrical Code exists specifically because electrical failures follow predictable patterns — patterns a licensed electrician is trained to read. Why Waiting Usually Costs More Than Calling Now The biggest misconception about emergency electrical services is that calling immediately is the most expensive option. Waiting is usually what drives the cost up. If I get there early, I can often catch a loose connection, overloaded circuit, or failing breaker before it damages more of the system. If you wait until there's smoke, melted wiring, or half the house has no power, the repair scope is significantly larger. I've seen neglected panels with loose breakers, corrosion, and heat damage — and the owner almost always says the same thing: "It had been acting up for a while." Flickering lights and tripping breakers were there weeks before the full failure. For commercial properties , the math is worse. A panel failure that shuts down a restaurant or warehouse means the repair bill is only part of the damage — lost business hours can hurt far more than the electrical invoice. How to Get a Faster Response When You Call Specific details are the single fastest way to get better service. Don't just say "my power is out." Instead, say: "My breaker keeps tripping." "I smell burning near the panel." "The outlet is hot." "Only half the house has power." "I saw a spark." "My business has no power to the front counter." Specific language helps me assess severity, prioritize your call correctly, and arrive with the right parts and tools the first time. If I ask for photos, send them. A picture of the panel, burned outlet, or damaged area can save significant diagnostic time on arrival and cut your wait in half. Emergency Electrical Services for Homes and Businesses Homeowners usually call when something feels dangerous — a burning smell, sparks, a breaker that won't stay on. Commercial clients typically call when the problem stops operations: lights out in a store, no power to equipment, a panel issue affecting the floor. For both, the best thing you can do right now is keep your panel area clear, label every breaker, and treat recurring warning signs as action items. Electrical problems don't fix themselves. Don't Wait Until It's a Bigger Problem If you recognized any warning signs here — flickering lights, warm outlets, burning smells, repeated breaker trips — that's your home or business telling you something is wrong. Call a licensed electrician now. Describe exactly what you're seeing. The call is free, the information helps, and getting ahead of an electrical problem is always cheaper than dealing with the aftermath. Emergency electrical services are available 24/7 for a reason — use them before a small issue becomes a dangerous one. Oliver Electric LLC https://www.oliverelectricaz.com/ 623-387-9171
