No dedicated parking or panel access. Use public 120V outlets or ask your building for a NEMA 14-50.
Campgrounds and RV parks often have NEMA 14-50 outlets. A portable Level 2 gets you 20 miles/hr anywhere.
Keep a Level 1 charger in your car as an emergency backup. Works at any standard 120V outlet.
| Outlet | Voltage | Amps | kW | Miles/Hour | Full Charge (75 kWh) |
|---|---|---|---|---|---|
| NEMA 5-15 (standard) | 120V | 12A | 1.4 kW | ~4 miles | ~52 hours |
| NEMA 5-20 (20A outlet) | 120V | 16A | 1.9 kW | ~6 miles | ~39 hours |
| NEMA 14-30 (dryer outlet) | 240V | 24A | 5.8 kW | ~20 miles | ~13 hours |
| NEMA 14-50 (RV/range) | 240V | 40A | 9.6 kW | ~28 miles | ~7.8 hours |
| NEMA 6-50 (welder outlet) | 240V | 40A | 9.6 kW | ~28 miles | ~7.8 hours |
Ask your building manager about right-to-charge laws in your state. California, Colorado, New York, and 10+ other states require landlords to accommodate EV charging requests.
Look for NEMA 14-50 outlets in your parking garage — buildings with electric dryers, EV parking, or workshop spaces often have them. One 14-50 outlet + a portable charger = Level 2 charging for under $250.
Use public Level 2 stations for daily charging and keep a Level 1 charger at home for top-ups. Many workplaces, shopping centers, and destinations have free or low-cost Level 2 charging.
