Rivian
The best home charger for a Rivian
A large battery is the one case where paying for maximum amperage genuinely pays back. Here is the connector answer and the sizing logic.

The connector
Published lists put the refreshed 2026 R1T and R1S on a native NACS port. Earlier cars use the CCS standard, whose upper section is a J1772 inlet -- so a J1772 home charger plugs straight in. Cars sold with a NACS port ship with a J1772 adapter, so a J1772 charger remains the versatile choice either way. Go and look at your charge port rather than relying on a table.
Why battery size changes the amperage answer
Most of this site argues against overbuying amperage, because a typical car replaces a typical day's driving in an hour or two regardless. A large-battery truck or SUV is the honest exception.
Why a bigger battery wants more amps
A large pack, run from 20% to 80%, is a lot of energy to move -- often 70 kWh or more.
At 32 A (7.7 kW): roughly 9 hours
At 48 A (11.5 kW): roughly 6 hours
The first fits an overnight window with nothing to spare. The second fits comfortably.
Add towing, which can cut efficiency dramatically, and the case for the 48-amp unit and its 60-amp circuit becomes straightforward rather than marginal. Confirm your panel can carry it -- breaker and wire size.

Cable length matters more on a big vehicle
An R1T is a long truck. Where the charge port sits relative to your wall, and how you park, matters more than on a compact car. Measure the real path before choosing -- how to measure -- and lean toward the longer cable.
The chargers in detail
Three 48-amp-capable units, with the case against each.
1. A first charger, hardwired
Emporia Level 2 EV Charger (Classic)
Emporia · J1772 · 48 A / 11.5 kW · 24 ft cable
The safe default for a first home charger: 48 amps hardwired, a genuinely long cable, a NEMA 4 outdoor-rated case, and no subscription attached to the app.
What is good
- 48 A hardwired is the fastest tier most homes can realistically support
- 24 ft of cable reaches across a two-car garage without a fight
- NEMA Type 4 enclosure is rated for outdoor mounting
- Energy monitoring in the app with no subscription
What is not
- Drops to 40 A if you use the NEMA 14-50 plug rather than hardwiring
- The app is the only way to change the amperage setting
| Maximum output | 48 A / 11.5 kW at 240 V (hardwired) |
|---|---|
| Plug-in output | 40 A with the NEMA 14-50 plug |
| Connector | SAE J1772 |
| Cable | 24 ft |
| Enclosure | NEMA Type 4, indoor or outdoor |
| Certification | UL listed, Energy Star |
| Warranty | 3 years |
Skip this if: Skip it if you want a unit with no app or network connection at all. The Grizzl-E Classic is the simpler machine.

2. Tight wall space
Wallbox Pulsar Plus
Wallbox · J1772 · 48 A / 11.5 kW · 25 ft cable
The smallest 48 A unit here at roughly 7.8 by 7.9 inches, which matters more than it sounds when the only free wall is beside a door.
What is good
- Smallest body of the 48 A units, under 8 inches square
- Current configurable in steps from 6 A to 48 A
- NEMA Type 4 enclosure, rated down to -22 F
- Weighs 4.4 lb without the cable, so mounting is simple
What is not
- Hardwired only at 48 A, with no plug-in version at full output
- Setup runs through the app, which some owners find fussy
| Maximum output | 48 A / 11.5 kW at 240 V |
|---|---|
| Configurable current | 6 A to 48 A |
| Connector | SAE J1772 |
| Cable | 25 ft |
| Body size | 7.8 x 7.9 x 3.9 inches without the cable |
| Operating temperature | -22 F to 104 F |
| Certification | UL 2594, UL 2231 |
| Warranty | 3 years |
Skip this if: Skip it if you want a plug-in unit you can take with you. The 48 A Pulsar Plus is hardwired.

3. Homes with an uncertain panel
ChargePoint Home Flex
ChargePoint · J1772 · 50 A / 12 kW · 23 ft cable
The most adjustable unit here. It can be set anywhere from 16 A to 50 A, which makes it the one to buy when you do not yet know what your panel will allow.
What is good
- Six selectable amperage settings from 16 A to 50 A
- Sold in both hardwired and NEMA 14-50 versions
- Rated for indoor or outdoor installation
- The app is mature and does not require a subscription
What is not
- 23 ft is a foot shorter than the longest cables in this group
- The 50 A setting needs a bigger circuit than most panels have spare
| Maximum output | 50 A / 12 kW at 240 V |
|---|---|
| Amperage settings | 16, 24, 32, 40, 48 or 50 A |
| Connector | SAE J1772 |
| Cable | 23 ft |
| Installation | Hardwired or NEMA 14-50 |
| Certification | UL listed, Energy Star |
| Warranty | 3 years |
Skip this if: Skip it if your circuit is already fixed and you just want the cheapest safe 40 A unit. You are paying for flexibility you will not use.
