The car arrives in three weeks. The dealer said "you'll want to get a Level 2 installed." That is roughly where most of these conversations start, and there is usually more to it than plugging something into the garage wall.
Level 1, Level 2 and why nobody stays on Level 1
Level 1 is the cord that came in the trunk, plugged into a standard 120V outlet. It adds roughly three to five miles of range per hour. If you drive twenty miles a day and the car sits overnight, that genuinely works.
Level 2 runs on a 240V circuit and adds roughly twenty to forty miles per hour depending on the car and the circuit size. For anyone commuting across the Las Vegas Valley or the Reno-Sparks area, that is the difference between waking up full and waking up planning around a charge.
Hardwired charger or a 14-50 outlet?
Both are legitimate. The trade-offs:
- Hardwired allows a higher continuous draw, removes the receptacle as a failure point, and looks tidier. Better for permanent installs and higher-amperage chargers.
- NEMA 14-50 outlet is flexible. Take the charger with you when you move, swap brands, plug in a welder. But the outlet itself becomes the weak link, and a cheap receptacle carrying 40 amps continuously in a hot Nevada garage is a real failure mode we see.
If you go with an outlet, the receptacle grade matters far more than people expect. We fit industrial-grade devices for exactly this reason.
Can your panel handle it?
This is the question that decides the job, and it is answered with a load calculation rather than a glance. We total the existing connected load against your service size and see what headroom remains. A 40 amp charger needs a 50 amp circuit, and that has to fit within the service, not just within the panel's empty slots.
If there is not enough room, you have three options:
- Upgrade the service. See our guide on 100 amp versus 200 amp service, or the panel upgrade page.
- Install a load management device, which lets the charger back off automatically when the AC and dryer are running. Often cheaper than a service change.
- Install at a lower amperage. A 24 amp charger still adds far more range overnight than Level 1 and fits in tighter service.
Where the charger should go
The obvious answer is the garage wall nearest the panel, and that is the cheapest install. But think about where the car's charge port sits and which way you park. A charger on the wrong wall means the cable stretches across the bay every night, which is how cables get damaged.
Outdoor and carport installs are common here. They need weather-rated equipment and conduit that will survive direct Nevada sun, which is not the same as "outdoor rated" in a milder climate. UV degradation on cheap conduit and cable jackets is real and we have replaced plenty of it.
How long the install takes
A straightforward garage install on a wall near the panel is typically a half day. Add time for:
- Long conduit runs, especially through attics or crawlspaces
- Outdoor routing and trenching to a detached garage or carport
- Panel upgrades or load management device installation
- Permit and inspection scheduling in your jurisdiction
Two cars, one garage
Households with two EVs usually do not need two full-capacity circuits. Power-sharing chargers split a single circuit between two units, charging both more slowly or one at full speed. Given overnight hours, that is almost always sufficient and considerably cheaper than a second service-level circuit.
Booking it
Tell us the car, the panel size and where you park, and we can usually scope the job on the phone before we visit. We install Tesla Wall Connectors, universal connectors and every mainstream brand, including units you already bought. Full details are on the EV charger installation page.
