The short answer
The Grand Cherokee 4xe's maximum battery charge rate via J1772 is 7.2 kW, in the same 32 A class as the Wrangler 4xe. Buy a 32 A charger on a 40 A breaker with 8 AWG copper. EPA publishes a 3.4-hour 240 V charge time for the 2026 model — a larger battery than the Wrangler's, and still a short charge.
If you have read our Wrangler 4xe page, the conclusion here is the same and for the same reason. What differs is the battery size and therefore the charge time: 3.4 hours against 2.4.
The constraint: what this car accepts
Everything else on this page follows from one number. The Jeep Grand Cherokee 4xe's onboard charger accepts a maximum of 7.2 kW, which is 32 amps at 240 volts. No wall charger can exceed it, and a charger rated above it delivers no extra speed.
| Specification | Value | Source |
|---|---|---|
| Maximum AC power accepted | 7.2 kW | Grand Cherokee 4xe maximum battery charge rate via J1772 |
| Maximum AC current at 240 V | 32 A | Grand Cherokee 4xe charging specification |
| Connector | J1772 | Jeep 4xe charging information |
| EPA range (2026 Grand Cherokee 4xe) | 470 mi | US DOE / EPA fueleconomy.gov |
| EPA efficiency | 58 kWh / 100 mi (23 MPGe) | US DOE / EPA fueleconomy.gov |
| EPA published 240 V charge time | 3.4 hours | US DOE / EPA fueleconomy.gov |
The consequence: the circuit you actually need
Take the car's 32 A ceiling and work backwards. NEC 625.42 classifies EV charging as a continuous load, and NEC 625.41 requires overcurrent protection at not less than 125% of the maximum load — so a 32 A charger needs a 40 A two-pole breaker and 8 AWG copper at the 75 degC column of NEC Table 310.16.
| Item | This car | Why |
|---|---|---|
| Charger output | 32 A | Matches the car's 32 A ceiling exactly |
| Power delivered | 7.2 kW | The lower of the charger's output and the car's limit |
| Breaker | 40 A, two-pole | NEC 625.41 — 125% of a continuous load |
| Copper conductor (conduit, 75 degC) | 8 AWG | NEC Table 310.16 |
| A bigger charger would | charge this car no faster. 32 A is a hardware limit inside the vehicle | The lower of the two numbers always wins |
Charge times, with the arithmetic shown
EPA rates the 2026 Grand Cherokee 4xe at 58 kWh per 100 miles. That single figure lets you calculate any charge time you like, and it is why we show the formula rather than asserting a number.
hours = (miles x 58 / 100) / (kW x 0.9)
At 7.2 kW, this car gains about 11 miles of range per hour
The 0.9 allows for AC-to-DC conversion losses in the onboard charger — roughly 10% of what your meter records never reaches the battery. EPA efficiency figure from the US DOE / EPA fueleconomy.gov service, 2026 Grand Cherokee 4xe, queried 2026-10-05.
| Charger | Miles added per hour | Hours to add 100 miles |
|---|---|---|
| 16 A (3.8 kW) | 6 | 16h 58m |
| 24 A (5.8 kW) | 9 | 11h 07m |
| 32 A (7.7 kW) | 11 | 8h 57m |
| 40 A (9.6 kW) | 11 | 8h 57m |
| 48 A (11.5 kW) | 11 | 8h 57m |
For context, EPA's own published figure for a full charge at 240 V on this trim is 3.4 hours.

Connector and adapters
The Jeep Grand Cherokee 4xe uses a J1772 port for AC charging, which is what the large majority of home chargers in the US have. No adapter is needed for a J1772 charger.
You need a NACS to J1772 adapter only if you intend to use a Tesla Wall Connector, a Tesla Destination charger or a Tesla Mobile Connector. Rated headroom matters on a part carrying 48 A for eight hours — see best NACS to J1772 adapters.

What the two 4xe models have in common
| Wrangler 4xe | Grand Cherokee 4xe | |
|---|---|---|
| Max AC charge rate | 7.7 kW / 32 A | 7.2 kW / 32 A class |
| Connector | J1772 | J1772 |
| Charger to buy | 32 A | 32 A |
| Breaker | 40 A | 40 A |
| Copper (conduit) | 8 AWG | 8 AWG |
| EPA 240 V charge time (2026) | 2.4 h | 3.4 h |
| EPA electric consumption | 68.0 kWh / 100 mi | 58.0 kWh / 100 mi |
| EPA total range | 370 mi | 470 mi |
The Grand Cherokee is the more efficient of the two in electric mode — 58 kWh per 100 miles against the Wrangler's 68 — which is unsurprising given the Wrangler's aerodynamics. Both are thirsty by BEV standards, which is normal for a plug-in hybrid with a small battery and a lot of mass.
A 32 A circuit is a genuinely cheaper install
This is where buying the right size pays. Against a 48 A install, a 32 A one needs:
- A 40 A breaker instead of a 60 A one, which is a cheaper part and a smaller addition to your load calculation.
- 8 AWG copper instead of 6 AWG — meaningfully less material cost, and dramatically easier to pull through tight bends on a long run.
- 8/2 NM-B instead of 6/2, if the run is indoor cable rather than conduit.
- Less chance of a panel conversation. 20 A of calculated demand is the difference between fitting comfortably and needing a load calculation argued.
None of which costs you a single minute of charge time on this vehicle.
Level 1 or Level 2?
The Grand Cherokee's larger battery tilts this slightly further toward Level 2 than the Wrangler does. On Level 1 — approximately 5 miles of range per hour per the US DOE — a full charge is a long overnight. On 32 A it is 3.4 hours.
The deciding question is the same: do you ever need a second electric charge in a day? If yes, Level 2. If the car sits overnight and you are content to run on gasoline when the battery empties, Level 1 is defensible. Our PHEV guide works through it properly.
Hardwire it if you can
On a 32 A charger the hardwired-against-plug-in decision is cleaner than usual, because the 40 A ceiling of a NEMA 14-50 receptacle is not a constraint here — the car only wants 32 A anyway. So plug-in costs you nothing in speed.
What hardwiring still buys you is no GFCI breaker (NEC 625.54 applies to receptacles, not to directly connected equipment) and no receptacle to loosen over a decade of nightly use. If you own the house, hardwire. If you might move, plug in — the charger comes with you. The full comparison.
What to buy for a Grand Cherokee 4xe
A hardwired 32 A unit is the clean answer. The portable 40 A is there because it is cheap, it travels, and the car cannot use more than 32 A of it anyway.
