Energy Star
The best ENERGY STAR certified EV chargers
Every charger below appears in the EPA's own list of certified chargers, not just on the box. Here is what the label means, what it does not, and how to check a model yourself.

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.
A charger spends much of its life plugged into the wall with no car attached, and an efficient one wastes less while it waits and while it works. ENERGY STAR's own estimate: if every EV charger sold in the US met its requirements, energy-cost savings would grow to more than $17 million and 280 million pounds of greenhouse gas emissions would be avoided.

What the EPA's list shows
| Charger on this site | Model listed | Maximum current, as listed |
|---|---|---|
| Emporia Level 2 | EMEVSE1 | 48 A |
| ChargePoint Home Flex | CPH50 | 50 A |
| Wallbox Pulsar Plus | Pulsar Plus NA (PUP1 and PUP2 series) | 48 A |
| Grizzl-E Classic | GR1-14-24 (6-50 versions also listed) | 40 A |
| Autel MaxiCharger | Maxi US AC W12 and W10-N14-H | 50 A and 40 A |
How to check a charger yourself
- Find the exact model number on the listing or the box -- not just the product name.
- Search it in ENERGY STAR's product finder or the certified-charger dataset, both linked at the foot of this page.
- Match the variant. Plug-in and hardwired versions, and different cable lengths, often carry different model numbers.
What the label does not tell you
- Safety. ENERGY STAR covers efficiency. Electrical safety is a separate lab listing -- what the safety marks mean and UL-listed chargers.
- Speed. A certified 40 A unit charges no faster or slower than an uncertified 40 A unit.
- Whether it suits your circuit. That is still how many amps you need.
The certified picks in detail
Five chargers with ENERGY STAR listings, each with the case against it.
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. 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.

3. 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.

4. Harsh weather and no app
Grizzl-E Classic
United Chargers · J1772 · 40 A / 9.6 kW · 24 ft cable
A cast-aluminum box with no app, no account and no firmware to update. If you want a charger that behaves like an appliance, this is the one.
What is good
- Cast aluminum NEMA 4 / IP67 enclosure, built for outdoor mounting
- No app, no account, no network dependency
- 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
| Maximum output | 40 A / 9.6 kW at 240 V |
|---|---|
| Adjustable | 16, 24, 32 or 40 A |
| Connector | SAE J1772 |
| Cable | 24 ft on the Extreme Edition |
| Enclosure | Cast aluminum, NEMA 4 / IP67 |
| Certification | UL certified |
| Warranty | 3 years |
Skip this if: Skip it if you want scheduled charging or energy tracking in an app. The Classic deliberately has neither.

5. Long reach outdoors
Autel MaxiCharger AC Home
Autel Energy · J1772 · 50 A / 12 kW · 25 ft cable
The 25 ft cable is the longest in this group, and the NEMA 4 case plus a cold-flexible cord make it the easiest unit to live with on an exposed outside wall.
What is good
- 25 ft cable, the longest of the wall units here
- Sold in NEMA 14-50, NEMA 6-50 and hardwired versions
- NEMA Type 4 enclosure rated for rain, snow, hail and sleet
- Wi-Fi and Bluetooth, so it still works if the Wi-Fi drops
What is not
- The 50 A version is hardwired only
- The app has more features than a first-time owner needs
| Maximum output | 50 A / 12 kW hardwired; 40 A / 9.6 kW plug-in |
|---|---|
| Connector | SAE J1772 |
| Cable | 25 ft |
| Enclosure | NEMA Type 4 |
| Certification | Tested to UL standards by CSA |
| Warranty | 3 years |
Skip this if: Skip it if your parking spot is right next to the panel. You are paying for cable you will coil up and never use.
