240 volt picks
The best 240V EV chargers for a home
Every home Level 2 charger is a 240-volt charger. If that sentence is news, this is the page to start on.

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.
Let us clear this up first, because it is the single most common source of confusion for a first-time buyer: "240-volt charger" and "Level 2 charger" are the same thing. There is no separate category. If a product is sold as a Level 2 home charger, it runs on 240 volts.
So the real question is not which 240-volt charger to buy but which Level 2 charger to buy, and that comes down to three specs. This page answers it; charging levels explained covers the underlying idea if you want it first.

Why 240 volts changes everything
The arithmetic
Level 1, a normal outlet: 12 A x 120 V = 1.44 kW
Level 2 at 32 A: 32 x 240 = 7.7 kW -- more than five times as fast
Level 2 at 48 A: 48 x 240 = 11.5 kW -- eight times
Power is volts multiplied by amps. Double one and raise the other and the product climbs quickly.
In practical terms: about 5 miles of range per hour on 120 V, against 27 to 40 miles per hour on 240 V. That is the difference between a car that never quite catches up and one that is full every morning.
What a 240V circuit involves
A 240-volt circuit uses two hot conductors instead of one, which is why it needs a double-pole breaker taking two adjacent slots in your panel. You may already have one feeding a range, a dryer or a workshop outlet -- and if it is within reach of where you park, a plug-in charger may need no new wiring at all.
- Already have a spare 240 V outlet? A plug-in unit could be a same-day job. Plug-in picks.
- Need a new circuit? That is the expensive half of the project. What installation costs.
- Not sure what your panel can carry? Buy an adjustable unit and set it to whatever the electrician confirms.
The 240V chargers in detail
Three units covering the common answers, 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. 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.

What we would do
Emporia if your electrician has confirmed a 60-amp circuit. ChargePoint Home Flex if your panel capacity is still a question mark, because it adjusts from 16 to 50 amps. Grizzl-E if you want a machine with physical switches and no software in it at all.
