Audi’s US e-tron lineup spans four different onboard AC charger ratings 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 — and none of them come close to the 22kW three-phase charging some European Audi e-tron buyers get as a factory option. That’s not a charger problem to shop your way out of: three-phase electrical service isn’t run to American homes, so a 22kW home charger has nothing to plug into in the US regardless of price. The real decision is simpler than it looks — pick a 40A or 48A charger based on which e-tron is in the garage, and size the circuit right.
Audi e-tron home charger picks compared
| Charger | Best for | Output | Breaker needed | Price |
|---|---|---|---|---|
| ChargePoint Home Flex | Any e-tron, configurable | 48A HW / 40A plug (dial down to 16A) | 60A or 50A | ~$549 |
| Autel MaxiCharger AC Wallbox | Budget 48A option | 48A HW / 40A plug (dial down to 16A) | 60A or 50A | $399-549 |
| Grizzl-E Classic | Original e-tron only, best value | 40A / 9.6 kW | 50A | ~$299.99 |
None of these units make an original e-tron, Q8 e-tron, or Q6 e-tron charge faster than another of the same amperage class — the car’s own onboard charger sets the real ceiling. The differences that matter are price, whether the amperage is fixed or configurable, and the circuit size an electrician needs to run.
1. ChargePoint Home Flex — Best for Any Audi e-tron
ChargePoint Home Flex
- Configurable amperage covers every US-spec Audi e-tron's onboard charger — 9.6kW original e-tron and Q6 e-tron, or 11kW Q8 e-tron and e-tron GT — from one unit, useful if a household has more than one e-tron model or plans to trade up.
- Hits the full 48A/11.5kW ceiling for the Q8 e-tron and e-tron GT rather than leaving capacity on the table.
- See our full ChargePoint Home Flex review for the hardwired-vs-plug breakdown across its variants.

2. Autel MaxiCharger AC Wallbox — Best Budget Pick
Autel MaxiCharger AC Wallbox
- The cheapest way to hit the same 48A ceiling as the Q8 e-tron and e-tron GT's onboard chargers, with a color touchscreen that works without pairing a phone app.
- Read our full Autel MaxiCharger review for how it compares on price and features against ChargePoint.
3. Grizzl-E Classic — Best Value for the Original e-tron
Grizzl-E Classic
- Matches the original e-tron's as-supplied 9.6kW/40A onboard charger exactly, at a lower price than the 48A units built for the Q8 e-tron and e-tron GT's full output.
- NEMA 4 enclosure handles an outdoor mount without extra weatherproofing — see our best outdoor EV charger guide for how it compares to other rugged picks.
- Not the right pick if the original e-tron's onboard hardware is later paired with a Q8 e-tron or another 48A-capable EV in the same household — a fixed 40A unit can't be turned up.
Why the 22kW upgrade doesn’t apply in the US
Some European Audi e-tron buyers can option a 22kW three-phase onboard charger, cutting a full overnight charge down dramatically compared to single-phase AC. It’s a real spec sheet line — and one that shows up often enough in online e-tron discussions that US buyers sometimes go looking for a “22kW home charger” to match it. That charger doesn’t exist for American driveways because the electrical service behind it doesn’t either: US residential power is split-phase 240V, not three-phase, so there’s no wiring path to deliver 22kW to a home charger regardless of brand or price. The practical ceiling for every US-spec e-tron is 48A/11.5kW, full stop, and every charger in this guide is sized around that real number rather than a spec that only applies overseas.
The bottom line
Match the charger to the e-tron in the garage, not to a European spec sheet. The ChargePoint Home Flex covers the whole US e-tron lineup with configurable amperage, making it the safest single purchase for households with more than one e-tron model or plans to trade up from an original e-tron to a Q8 e-tron or e-tron GT. Original-e-tron-only garages can save real money with the Grizzl-E Classic at 40A, since the car’s as-supplied onboard charger never asked for more. Either way, size the circuit to the charger you buy — our EV charger installation cost guide breaks down what that electrical work runs, and our best home EV charger roundup covers picks outside the Audi-specific lane this guide focuses on.
