Frequently asked questions

Yes. The requirement is access to an outlet where the car parks, not a garage. An ordinary 120V socket adds roughly 3 to 5 miles of range per hour, which covers a typical daily commute overnight, and a 240V outlet you can reach makes it substantially faster. The pillar guide works through all four routes.

Survey the property for existing outlets first — carport walls, exterior receptacles, storage areas and especially the shared laundry room, which is the most overlooked 240V circuit in rental housing. Buy for what you find. Only if nothing is reachable do you need a conversation with the building, and the playbook covers how to make that ask.

Yes — any plug-in charger. A charger that ends in a NEMA plug is an appliance, not an installation, and it unplugs and leaves with you at the end of the lease. Installation is only needed to add a circuit where no suitable outlet exists. Every no-install option, ranked.

Sometimes. If the car parks on your own property line with no public path in between, a Level 1 charger and a correctly routed cable work. If a public sidewalk sits between the outlet and the car, home charging is not realistically available and the honest answer is a routine built on workplace and public charging — covered here.

For most commuters, yes. Twelve hours on a 120V socket returns roughly 40 to 60 miles, which exceeds what the median US driver covers in a day. It stops being enough when your daily driving regularly exceeds that — the full comparison.

Yes. A dryer outlet is 240V and supports 24 amps of continuous EV charging, about 5.8 kW — roughly 200 miles over a twelve-hour night. If the dryer still needs the circuit, an automatic splitter shares it and gives the dryer priority.

Take the circuit breaker rating, multiply by 0.8, and buy a charger that can be set at or below that number. A 30 amp circuit means 24 amps; a 50 amp circuit means 40. Your car’s onboard charger caps it further if it is lower — the method in full.

Count the openings first: two small plus a round hole is 120V household, three large is a three-wire 240V outlet, four large is a modern four-wire one. The shapes narrow it from there, and the identification guide does it from a photograph in about a minute.

The second name in the product title is always your car. A J1772 car using a Tesla cable needs a NACS-to-J1772 adapter; a NACS car using a J1772 cable needs a J1772-to-NACS adapter. Getting it backwards is the most common purchase mistake in the category — the direction guide.

Yes, and which side matters more than anything else about it. A J1772 extension between the charger and the car keeps the EVSE upstream, still limiting current and monitoring the ground. A household cord between the wall and the charger puts unmanaged wire ahead of everything that does the protecting — the full answer, with the specification.

No. Superchargers are DC and every adapter on this site is AC-only. The connector shape being identical is exactly why the question comes up — why AC and DC are different technologies.

Divide your all-in electricity rate by your car’s miles per kWh to get cost per mile. For a full charge, multiply usable battery capacity by your rate and divide by about 0.88 to allow for charging losses. Both formulas are worked through on cost to charge — we do not publish a national average, because it would be wrong for almost everyone.

In most US states there is no explicit statutory right for tenants. Right-to-charge laws predominantly protect condo and HOA owners with deeded or exclusive-use parking, and a minority of states extend narrower provisions to renters — the honest version, including where the real leverage is.

No — none of them, and we say so on every page where it is relevant. There is no lab, no bench and no loaner hardware behind this site. What we do instead is compile published specifications, cite the standards behind every safety claim, and print the arithmetic so you can re-run it — the method in full.

Because the live price layer has nothing fresh for that product. Prices older than 48 hours disappear automatically rather than going stale on the page, and we never display a remembered number. That is the system working as designed — how the links and prices work.
