Home charging a Jeep 4xe

How this page is funded: we earn a commission if you buy through our Amazon links, at no extra cost to you. It does not change what we recommend, and we say plainly when the honest answer is to buy nothing. Full disclosure.

The verdict: buy a basic 40-amp Level 2 charger, have it put on a 50-amp circuit, and stop reading reviews. For a 4xe the difference between an entry-level charger and a top-of-the-range one is nothing at all, because both spend the night waiting on the car. If you have a dryer outlet where you park, use that instead and spend nothing on wiring. And if you park in a garage overnight and drive a normal commute, try the cord that came with the car for a fortnight before you buy anything -- on this battery the arithmetic says an overnight park is enough, and two weeks will tell you whether that holds for your driving.

The two 4xe models, by the EPA's figures

Why a big charger is wasted money here

Work the arithmetic from the EPA's own numbers and the answer falls out. Electric range multiplied by consumption gives the energy the battery actually holds, and energy divided by the published charge time gives the rate the car accepts:

Those last two lines are the whole page. A charger offers power; the car's onboard charger decides how much of it to accept, and on a 4xe that ceiling is somewhere in the twenties of amps. Buying 48 amps for this car is like buying a wider driveway to make the car accelerate. How long to charge at home explains the general version of this, and 32A vs 40A vs 48A is the tier decision for cars where it does matter.

Try the cord first

This advice gets given to electric-car buyers and almost never lands, because 15 hours on a 120-volt outlet is not a plan for a 70 kWh battery. On a 4xe it is different, because the battery is about 15 kWh:

Eleven hours is a long night but it is a real one. Do not over-read it, though: a 20-mile day costs about 14 kWh on a Wrangler, which is most of the battery and close to ten hours on the cord, and about 12 kWh on a Grand Cherokee, which is nearer eight. Level 1 genuinely works for a 4xe, with little margin left over. The Department of Energy's general figure for Level 1 is about 5 miles of range per hour, which lines up. Level 1 chargers covers what the supplied cordset will and will not do, and the honest test is free: plug in for two weeks and see whether you ever start a morning short.

Two conditions, though. The outlet must be a proper grounded receptacle on a circuit that is not carrying much else -- never an extension cord or a power strip, which is a genuine fire risk rather than an inconvenience (why). And if you have a second car to charge, or you drive the electric range twice in a day, Level 1 stops being enough quickly.

The dryer-circuit route

If Level 1 is too slow and a new circuit feels like overkill, a 30-amp dryer outlet sits exactly in between -- and for this car it is not a compromise at all. A 30-amp circuit allows 24 amps of continuous draw, which is already at or above what a 4xe accepts, so a dryer circuit delivers the car's full charging rate.

That makes the 4xe one of the few vehicles where the dryer outlet is a complete answer rather than a stopgap. The mechanics matter, though: sharing the circuit needs a switch rather than a double adapter, and a plain 14-30 to 14-50 plug adapter is the one shortcut to avoid. NEMA 14-30 vs 14-50 lays out the decision and charging from a dryer outlet is the full how-to.

If you do install a charger

1. 1.Buy on price and build quality, not amperage. Any unit rated 32 A or more covers this car completely. Spend the difference on a better enclosure or a longer cable instead.
2. 2.A 40 A charger wants a 50 A circuit, because an EV is a continuous load and the breaker is 125% of the charger's rating. That is the normal, inexpensive install.
3. 3.Check the cable reaches with the Jeep parked the way you actually park it, not measured in a straight line. This is the most-regretted spec in the category.
4. 4.An outdoor enclosure rating matters if the charger goes on an exterior wall -- look for a published NEMA Type 4 rather than a vague weatherproof claim.
5. 5.Skip the features you are buying for a car you do not own. Load management, 19.2 kW output and access control are all solving problems a 4xe does not have.

The circuit follows the charger's rating, not the car: 40 A needs 50 A, 32 A needs 40 A, 24 A needs 30 A. Breaker and wire size has the table, and how to set your EV charger's amps covers turning a charger down if your panel is tight.

What the electric miles are worth

It is worth charging even though the range is short, and the EPA quantifies it on the Grand Cherokee 4xe: about 8.7 cents per mile for the first 26 miles on a full battery, against about 18.3 cents per mile once the battery is empty and the car runs as an ordinary hybrid. That is roughly half price for the first 26 miles of every day, which for a commuter is most of the driving.

It also means the thing that matters is charging OFTEN rather than charging FAST. A 4xe that gets plugged in every night captures nearly all of the saving available to it on any charger at all; a 4xe with an expensive charger that gets plugged in twice a week does not. Cost to charge at home shows the method with your own electricity rate, and time-of-use charging covers scheduling it into the cheap window.

The connector, briefly

A 4xe charges on AC through a J1772 inlet, which is the same connector the Department of Energy describes for both Level 1 and Level 2 equipment, so the supplied cordset and any ordinary Level 2 charger use the same port. The EPA publishes only a 240-volt charge time for these models and no DC fast-charging figure; this page makes no claim either way about DC, because home charging is the subject and nothing we can read settles it. Plug types explained covers the connector landscape, and plug-in hybrids is the general version of this page for other PHEVs.

What to buy for a 4xe

A short list on purpose. Two chargers that cover this car completely, and the accessory everybody forgets. Live Amazon prices with the date they were read.

1. Harsh weather and no app

Grizzl-E Classic

United Chargers · J1772 · 40 A / 9.6 kW · 24 ft cable

• +Amperage is set with physical switches, not software
• +Protections for over-current, over-voltage, ground fault and over-temperature

What is not

• −40 A ceiling, slower than the 48 A units if your panel can take more
• −No scheduling, so off-peak charging has to be set in the car
• −The cold-flexible 24 ft cable is only on the Extreme Edition
