How Long Does EV Charger Installation Take?

The electrician is on site for two to six hours. The project usually takes two to four weeks. Both numbers are true at once, and the gap between them is where every frustrated expectation in this category lives. The wiring is a straightforward morning’s work for a qualified electrician. The permit, the inspectionand — if your panel is full — the utility each run on a clock nobody in your house controls.

The good news is that you can tell which path you are on before you book anyone. One question does most of the work: can your existing electrical panel carry the circuit? If yes, you are looking at a short, predictable project. If no, you are in service-upgrade territory and the timeline stops being measurable in weeks.

The stages, and who controls each clock

The one finding that changes everything

At the quote stage, ask for the load calculation. This is the arithmetic your electrician performs to the NEC to establish whether your service can carry a new continuous load on top of everything else the house runs. It is not optional and it is not a guess, and the answer sorts you into one of two very different projects.

If the panel has capacity, the job is a breaker, a conductor run, a charger on the wall and a permit. Two to four weeks door to door in most places, and the majority of that is waiting for other people’s calendars rather than work.

If the panel does not, you have three routes and they have very different durations. A subpanelif the service is adequate but the breaker space is gone — days added, not weeks. A charger with load management that throttles itself against whole-home demand, which can avoid the upgrade entirely and is the fastest fix of the three. Or a full service upgrade, which involves the utility, a meter swap and an appointment nobody can promise you. Weeks to months. Our small-panel roundup is the hardware answer to the middle route.

What stretches a straightforward install

Distance.The run from panel to charger is the single biggest variable in the labor. Fifteen feet along an open garage wall is quick. Sixty feet through a finished basement is not, and a long run also needs heavier conductors to hold the voltage drop down. A detached structure is the hardest version — see the detached-garage page.

Finished surfaces. Fishing cable through drywall is slow, occasionally impossible, and sometimes ends in cutting and patching. Exposed conduit on a garage wall is the fast and cheap alternative, and it is worth saying out loud at the quote stage that you are fine with it if you are.

The charger not being there. The most avoidable delay on this page. Order the unit when you accept the quote, and give your electrician the manufacturer’s installation instructionsin advance — that document is the authority on the terminals, the mounting and the circuit the maker specifies, and it occasionally changes what wire gets ordered. It is also where the neutral question gets settled.

Deciding late. Hardwired or plug-in is a conductor decision, and changing your mind after the wire is pulled is the expensive kind of late. Settle it with the comparison first.

The install that takes five minutes

Worth saying clearly, because a lot of people book an electrician who did not need one: if a suitable NEMA 14-50 outlet already exists within cable reach of where you park, there is no install. A plug-in or portable Level 2 charger goes on the wall or in the trunk and works today. No permit, no inspection, no appointment, and the charger comes with you when you move.

The two things to verify are that it is genuinely a 14-50 on its own dedicated circuit — an old dryer outlet is not— and that the receptacle is in good condition, because a worn 50-amp receptacle under a continuous load is a real failure mode. Our NEMA 14-50 guide covers both.

#	Product	Best for	Price
1	EVIQO 40A NEMA 14-50 Charger The most charger you can get without an electrician's invoice. It plugs into a NEMA 14-50 outlet for a full 40 amps, keeps the WiFi app, the ENERGY STAR listing and the 25 ft cable from EVIQO's hardwired unit, and can be unplugged and taken with you when you move.	No install on an existing 14-50	$449.99 · View on Amazon $510.9912% off Price as of October 18, 2026. #ad How we’re funded
2	ELEGRP 40A Portable Level 2 Charger The full-speed portable. A genuine 40 amps on a NEMA 14-50, an IP67 station body rated -22F to 122F, and a 25-foot cable - the longest here by five feet - for less than the 32A unit costs. It is the heaviest thing here to coil and there is no app, but if the portable is also going to be your everyday charger, this is the one that does not make you choose.

3	ChargePoint Home Flex The safest default for most homes: you set the amperage in the app to 16, 24, 32, 40, 48 or 50A, so one charger fits whatever circuit your panel can spare today and scales up if you upgrade later. The app is the most mature here, firmware arrives over the air, and the warranty is long.

4	Grizzl-E Ultimate 48A The tank of the 48-amp class: cast-aluminum body, IP67 sealing, a full 11.5 kW, a 25 ft cable built to stay flexible in the cold and a DIP switch instead of a setup wizard. We recorded it as discontinued in August 2026 after its Amazon listing went dark; Grizzl-E sells it and Amazon lists it again as of our 2026-09-28 check, so that record is corrected here.

While you wait

You are not stranded. Nearly every EV ships with a Level 1 cable that works from a standard 120-volt household outlet at roughly 5 miles of range per hour— slow, but around 60 miles overnight, which covers most commutes. Our Level 1 guide is honest about where that stops being enough. If a 240-volt outlet exists anywhere you can park, a cheap portable Level 2 unit bridges the gap properly and remains useful as a travel charger afterwards. And if you are still deciding whether the whole project is worth it, we ran that arithmetic for different mileages rather than assuming the answer.
