Onboard AC charger ratings in Audi’s US e-tron lineup come in four varieties, depending on model and year: 9.6kW as supplied on the original e-tron, 11kW on the Q8 e-tron, 9.6kW on the US-spec Q6 e-tron, and 11kW on the e-tron GT. None approaches the 22kW three-phase charging that some European Audi e-tron buyers can get as a factory option. Shopping your way around that gap won’t work, because American homes aren’t wired for three-phase service, so a 22kW home charger has nothing to connect to in the US at any price. The decision is actually more straightforward than it seems: choose a 40A or 48A charger according to which e-tron sits in your garage, and size the circuit correctly.

Among the chargers listed, none will get an original e-tron, Q8 e-tron, or Q6 e-tron charging faster than another in the same amperage class, since the car’s own onboard charger determines the true limit. What sets them apart is price, whether the amperage is fixed or adjustable, and the size of circuit an electrician has to install.
1. ChargePoint Home Flex — Best for Any Audi e-tron
ChargePoint Home Flex
Best for Any Audi e-tron · ~$549
- From one unit, adjustable amperage covers the onboard charger of every US-spec Audi e-tron (9.6kW on the original e-tron and Q6 e-tron, 11kW on the Q8 e-tron and e-tron GT), which helps a household with several e-tron models or one planning to trade up.
- It reaches the complete 48A/11.5kW ceiling that the Q8 e-tron and e-tron GT can use, leaving no capacity unused.
- Our full ChargePoint Home Flex review explains the hardwired-versus-plug differences among its variants.
- Fitting out a garage for an e-tron and hoping to finish the rest of the setup quickly? A free 30-day Prime trial brings cable organizers, a NEMA 14-50 outlet cover, and everything else listed on this page to your door in two days.

WenStorm Level 2 Portable EV Charger
Best Portable Pick (No Install) · $219.99
- From an existing NEMA 14-50 outlet it supplies up to 32A / 7.7 kW through a 25-foot cable, which comes near the 9.6 kW that the original e-tron and Q6 e-tron can take.
- The J1772 version, priced at $219.99 with a 2-year warranty, fits the e-tron’s port for AC charging.
- It is plug-in only, requires a NEMA 14-50 outlet, stops at 32A / 7.7 kW, and offers no app or Wi-Fi scheduling.
- The control electronics are housed in the connector handle and not in a separate inline box, and a 16/24/32A current dial lets you turn it down when the circuit behind the outlet turns out smaller than expected.
- A NACS version costs the same $219.99, although the e-tron’s port takes the J1772 version, and no hardwired option exists.

Autel MaxiCharger AC Wallbox
Best Budget Pick · $399-549
- This is the least expensive way to reach the 48A ceiling matching the Q8 e-tron and e-tron GT onboard chargers, and its color touchscreen works with no phone app pairing.
- Our full Autel MaxiCharger review compares its price and features with ChargePoint.
Check Price →4. Grizzl-E Classic — Best Value for the Original e-tron
Grizzl-E Classic
Best Value for the Original e-tron · ~$299.99
- It lines up exactly with the original e-tron’s as-supplied 9.6kW/40A onboard charger, and costs less than the 48A units designed for the full output of the Q8 e-tron and e-tron GT.
- Thanks to a NEMA 4 enclosure, it can be mounted outdoors with no added weatherproofing; our best outdoor EV charger guide shows how it stacks up against other tough picks.
- A poor fit if the household might later add a Q8 e-tron or another 48A-capable EV alongside the original e-tron, because a fixed 40A unit can’t be turned up.
Check Price →Why the 22kW upgrade doesn’t apply in the US
A 22kW three-phase onboard charger is an option for some European Audi e-tron buyers, and it cuts a full overnight charge down sharply compared with single-phase AC. It appears on the spec sheet, and comes up often enough in online e-tron discussions that US buyers sometimes hunt for a “22kW home charger” to equal it. No such charger exists for American driveways, because the electrical service behind it doesn’t exist either: US residential power is split-phase 240V and not three-phase, leaving no wiring route to deliver 22kW to a home charger whatever the brand or price. For every US-spec e-tron the practical limit is 48A/11.5kW, period, and each charger in this guide is sized around that actual figure instead of a spec relevant only abroad. For a portable setup, the WenStorm Level 2 Portable's 32A / 7.7 kW still sits below that ceiling, so it trades speed for price and portability.
The bottom line
Pick the charger for the e-tron in your garage, not for a European spec sheet. The ChargePoint Home Flex serves the entire US e-tron lineup through adjustable amperage, which makes it the safest single purchase for households with more than one e-tron model or plans to move from an original e-tron to a Q8 e-tron or e-tron GT. Garages with only an original e-tron can save real money on the Grizzl-E Classic at 40A, as that car’s as-supplied onboard charger never asked for more. In any case, match the circuit to whichever charger you buy; our EV charger installation cost guide details what that electrical work costs, and our best home EV charger roundup covers picks beyond the Audi-focused scope of this guide. The WenStorm Level 2 Portable ($219.99) is the runner-up worth knowing for a portable, no-install setup: it plugs into an existing NEMA 14-50 outlet at 32A / 7.7 kW with a 25-foot cable, close to the 9.6 kW the original e-tron and Q6 e-tron accept. It caps at 32A and has no app or Wi-Fi scheduling, so the Q8 e-tron and e-tron GT will charge more slowly on it than on a 48A unit. WenStorm is the budget route if speed is not the priority.

Frequently Asked Questions
Which home charger suits an Audi e-tron best?
The best overall choice for the Audi e-tron lineup is the ChargePoint Home Flex (~$549). It reaches the full 48A/11.5kW ceiling that every US-spec e-tron can actually use, and its adjustable amperage (16-50A) lets a single charger serve an original e-tron, a Q8 e-tron, or a future second EV without a repeat purchase. Households with only an original e-tron can economize with the Grizzl-E Classic (about $299.99, 40A/9.6kW), because that model’s as-supplied onboard charger never drew the full 48A anyway. For a lower-cost portable alternative, the WenStorm Level 2 Portable offers 32A / 7.7 kW at $219.99.
Can the Audi e-tron charge at 22kW AC in the US?
No. In Europe, Audi offers a 22kW three-phase AC upgrade on some e-tron models, but US homes have split-phase 240V service and not three-phase, so nothing in an American home can deliver 22kW. Whatever charger you purchase, each US-market e-tron, Q8 e-tron, and Q6 e-tron tops out at 9.6-11.5kW AC, which rules out paying for a European-spec 22kW feature in the States.
How do the onboard chargers of the original e-tron and the Q8 e-tron differ?
A 9.6kW (40A) charging cable came standard with the original Audi e-tron (2019-2023), yet according to Audi ownership forums and charging guides its onboard charger hardware can take up to 11.5kW (48A) from a higher-output home unit. The Q8 e-tron, its 2024+ successor, put an 11kW onboard charger across the range, so the quicker speed is the default and doesn’t require hunting for third-party equipment.
What breaker size is needed for an Audi e-tron home charger?
The answer turns on the charger’s amperage, not the car’s. For a 40A charger you need a 50A breaker, and for a 48A charger a 60A breaker, because the NEC sizes continuous-load circuits at 125% of the charger’s rating (per NEC 625.41 and 210.20(A)). A 60A circuit prepares the installation for the future, even if today’s charger is set lower, since every US-spec e-tron model can use up to 48A. A WenStorm Level 2 Portable at 32A needs a 40A circuit and a NEMA 14-50 outlet.
Is the Audi Q6 e-tron slower to charge than the Q8 e-tron in the US?
A little, yes. Built on the newer PPE platform, Audi’s Q6 e-tron comes with a 9.6kW onboard AC charger in US-market cars, whereas Europe gets 11kW as standard on that same model; the US-spec Q8 e-tron’s onboard charger is 11kW. Both figures fall well under the ceiling of a 48A/11.5kW home charger, so the difference appears in overnight charging time and doesn’t affect which home charger to choose; the same 48A units in this guide suit both.
Is the WenStorm Level 2 Portable good for an Audi e-tron?
It serves as an inexpensive portable choice. The WenStorm Level 2 Portable delivers 32A / 7.7 kW from a NEMA 14-50 outlet, close to the 9.6 kW the original e-tron and Q6 e-tron accept, at $219.99 with a 2-year warranty. It caps at 32A and has no app or Wi-Fi scheduling, so a Q8 e-tron or e-tron GT will charge slower than on a 48A unit.
