For most US Audi EVs the right home charger is a 40-amp unit, not a 48-amp one. Audi of America's own pricing release for the Q6 e-tron says Level 2 AC charging "is supported at rates up to 9.6kW (240V/40A)", and lists a 19.2 kW (240V/80A) onboard charger only as an upgrade "anticipated to be available at a later date". If you want one charger that covers every Audi in the driveway today and whatever replaces it, the Emporia Level 2 is the pick: it runs 48 amps when hardwired, falls back to 40 on a plug, and its energy monitoring is the simplest way to see what your car is really drawing. If you know your car is one of the 9.6 kW ones and you are not planning to change it, the EVIQO Level 2 saves you the hardwire and the 60-amp circuit for the same money.
This page exists because Audi is the one premium brand whose home-charging figure cannot be looked up in a single place. We skipped writing it twice for exactly that reason. Audi's global site says the Q6 e-tron charges "with up to 11 kW as standard"; Audi of America's release for the same car says 9.6 kW. Both are correct - for different markets - and the gap between them is the difference between a 50-amp circuit and a 60-amp one, which is real money. We compile published specifications and do the electrical arithmetic ourselves; we have not bench-tested these chargers and we do not run a test lab, so treat this as documented research rather than measurement.
What each US Audi actually accepts
Your real charging speed is the lowest of three numbers: the circuit, the charger, and the car's onboard AC charger. On an Audi the car is almost always the limit, so start there.
| Model | US AC rate | Charger that matches it | Source |
|---|
| Q6 e-tron / SQ6 e-tron | 9.6 kW (240V/40A) standard | 40 amps, on a 50-amp circuit | Audi of America release |
| Q6 e-tron with the optional onboard charger | Up to 19.2 kW (240V/80A), announced for later | 80 amps, on a 100-amp circuit | Audi of America release |
| A6 e-tron / A6 Sportback e-tron | 9.6 kW in the US (11 kW in Europe) | 40 amps, on a 50-amp circuit | Model reference |
| e-tron GT | 9.6 kW in the US (11 kW standard in Europe) | 40 amps, on a 50-amp circuit | Charging reference |
| Q8 e-tron / SQ8 e-tron (through Feb 2025) | 9.6 kW with Audi's supplied cord; 11 kW with a 48A charger | 48 amps, on a 60-amp circuit | Model reference |
| Q4 e-tron | About 11 kW on the MEB platform | 48 amps, on a 60-amp circuit | Shared with the VW ID.4 |
Two things in that table are worth saying out loud, because they invert the usual advice.
The newer, more expensive Audis take less AC power than the older cheaper one. The Q4 e-tron sits on VW's MEB platform and takes roughly 11 kW, the same as its ID.4 cousin. The PPE cars that replaced the Q8 e-tron at the top of the range - the Q6 and the A6 e-tron - are published at 9.6 kW in the US. Spending more on the car does not buy a faster home charge here.
On a Q8 e-tron, the 9.6 kW figure is the cable's limit, not the car's. Audi supplied a 40-amp J1772 cord with the car; the onboard charger itself will take 11 kW if you give it a 48-amp charger. That is the single clearest case in the Audi lineup for buying 48 amps rather than 40, and it applies to a car that is now used-market only.
How we ranked these
Five criteria, applied in this order. They are the same criteria we use on every charger roundup here, weighted for a lineup that mostly tops out at 40 amps.
- Does the amperage match the car, not exceed it?A 48-amp charger on a 9.6 kW Q6 charges at exactly the same speed as a 40-amp one, and costs you a 60-amp circuit and a hardwire to do it. Amperage above the car's ceiling is not headroom; it is a receipt.
- Is the safety listing published and checkable?A "certified" bullet is not a listing. We look for a named standard, a named laboratory, and ideally a file number.
- Plug-in or hardwired, and does that suit the install? A plug-in unit on a NEMA 14-50 is capped at 40 amps by the receptacle, which is a non-issue on most of this lineup and a limitation on a Q4 or Q8.
- Does the cable reach?Audi puts the charge port on the front fender - driver's side on the Q6 and A6, with a second AC-only port on the opposite side of the e-tron GT. A 25-foot cable means you do not have to care which way you parked.
- Does the software earn its price? Scheduling and energy monitoring pay for themselves on a time-of-use rate and are dead weight on a flat one.
What we deliberately did not rank on: brand matching. There is no electrical advantage to an Audi-branded wallbox, and every unit below uses the same J1772 connector your car was built around.
The connector question, settled
Every Audi EV sold in the US has a J1772 AC port, so no adapter is needed at home. Any Level 2 charger on this page plugs straight in.
Where it gets confusing is the NACS adapter Audi began shipping in September 2025. That adapter opened the Tesla Supercharger network to the e-tron GT, Q6 e-tron and A6 e-tron - and Audi states plainly that the Q4 e-tron cannot use it. More important for this page: it is a DC adapter. Audi says it is compatible only with DC fast-charging stations and will not work with NACS-capable Level 1 or Level 2 AC chargers, which includes Tesla Destination Chargers and a Tesla Wall Connector in your garage. If the charger already on your wall has a Tesla plug on the end, the part you need is a NACS-to-J1772 AC adapter, which is a different product entirely. Our does my VW or Audi need an adapter guide walks through every combination.
The circuit, and why 40 amps is usually the answer
EV charging is a continuous load under NEC Article 625, so the branch circuit is sized at 125 percent of the load - which is the same as saying the charger may draw no more than 80 percent of the breaker. That gives the ladder every charger on this site is ranked against:
- 50-amp circuit = 40 amps of charging = 9.6 kW. Can use a NEMA 14-50 receptacle, so the charger can be plug-in. This is the exact match for a Q6, SQ6, A6 e-tron or e-tron GT.
- 60-amp circuit = 48 amps of charging = 11.5 kW. Must be hardwired. Worth it on a Q4 e-tron or a Q8 e-tron, and worth it on any Audi if the circuit is going in from scratch and you expect the next car to be different.
- 100-amp circuit = 80 amps of charging = 19.2 kW. Relevant to exactly one Audi configuration: a Q6 e-tron with the optional onboard charger, if and when Audi ships it.
The practical consequence on a 9.6 kW car: upgrading from a 50-amp circuit to a 60-amp one buys you nothing at all. The car will not draw the extra amps. If an installer quotes you a panel upgrade to feed a 48-amp charger for a Q6 e-tron, that quote is solving a problem you do not have - and our installation quote checklist has the questions to ask before you sign it.
What a night actually looks like
The Q6 e-tron carries a 100 kWh gross pack, 94.4 kWh net. A realistic overnight is not 0 to 100 - it is a top-up. Going from 20 to 90 percent on that pack is about 66 kWh. At 9.6 kW that is roughly seven hours, which fits comfortably between dinner and the morning commute, and lands inside most off-peak windows. At a hypothetical 11.5 kW it would be about 5 hours 45 minutes. You are buying back roughly an hour of charging you were asleep for.
That arithmetic is why the amperage argument matters less than the install cost. The Department of Energy's figures for Level 2 put the whole category in the same bracket for overnight charging; the difference between 40 and 48 amps on an Audi is a rounding error against the difference between a plug-in install and a hardwired one on a new 60-amp circuit.
A note on where Audi's numbers come from
We would rather show our work than present a single confident number. For the Q6 e-tron:
- Audi of America, pricing and specifications release:"Standard Level 2 AC charging, most commonly used with home chargers, is supported at rates up to 9.6kW (240V/40A)", plus an optional onboard charger anticipated later for "AC charging rates up to 19.2 kW (240V/80A)". First-party, US-market.
- Audi global, battery and charging page: up to 11 kW as standard, with 22 kW as a later option. First-party, but written for a market with three-phase domestic power that North America does not have.
- Third-party charging references: consistently 9.6 kW, about 40 amps at 240 volts, for every US Q6 trim.
Two first-party sources, two different numbers, one market difference that explains it. If you want to settle it for your specific car rather than trust any page including this one, charge once on a 48-amp-capable charger and read the kW in the car's charging menu or in the charger's app. That is the whole reason the Emporia is our top pick here rather than a cheaper box: it tells you.
The picks, in one line each
- Emporia Level 2 - the one that covers every case. 48 amps hardwired, 40 on a plug, with energy monitoring that answers the question this page is about.
- EVIQO Level 2 - the exact match for a 9.6 kW Audi, double-listed, plug-in, at the same price.
- ChargePoint Home Flex - selectable from 16 to 50 amps, for a household that does not yet know which figure its car honors.
- Grizzl-E Classic - the no-app metal box for an Audi owner who schedules in the car and wants nothing else.
- Autel MaxiCharger 80A - only for a Q6 e-tron with the optional 19.2 kW onboard charger, and almost nobody has one.
Buying for an Audi: the three decisions
1. Settle your car's AC rate before you size the circuit
This is the decision that costs money if you get it wrong, and it is the one Audi makes hardest. Use the table above as the starting point, then confirm against your own car: the owner's manual lists the onboard charger rating, and the charging menu shows the live kW while plugged in. Do not use a European review, a European configurator, or Audi's global site - all three describe an 11 kW car that is not the one in your driveway.
If you cannot confirm it, size the circuit at 60 amps and buy a 48-amp-capable charger. You will have spent more on the electrician than you needed to, but you will never be capped by the wall. The reverse error - a 50-amp circuit under a car that wanted 11 kW - means opening the wall again.
2. Plug-in or hardwired
A NEMA 14-50 receptacle caps the charger at 40 amps, full stop. On a Q6, SQ6, A6 e-tron or e-tron GT that cap is below the car's ceiling anyway, so plug-in costs you nothing and buys you the ability to unplug the unit and take it to the next house. On a Q4 e-tron or a Q8 e-tron the cap is real, and hardwiring is how you get the last 1.5 kW. Our plug-in roundup and hardwired roundup cover each path in depth, and the NEMA 14-50 guide covers the receptacle itself, which is the part budget installs get wrong.
3. Cable length and where the port is
Audi puts the AC charge port on a front fender rather than the rear corner, and the e-tron GT has two ports - an AC-only one on the driver's side and an AC/DC one on the passenger side. The practical effect is that a short cable forces you to park a particular way round every single night. Every charger below ships a 25-foot cable except where noted. If your charger is already mounted and the cable is the problem, an extension is the fix, and a holster is what stops 25 feet of cable living on the garage floor.
What we would not buy for an Audi
- An 80-amp charger, unless you have the optional onboard charger. Audi announced the 19.2 kW upgrade as coming later and we have found no confirmation it shipped. A 100-amp circuit for a car that draws 40 amps is the most expensive mistake available here - our Enphase HCS-80 review is that mistake written out in full, on a unit that costs several times what an Audi owner needs to spend.
- A 16- or 32-amp unit to save money. The saving is small and the speed penalty is permanent. Our 32-amp page explains when that tier is genuinely right - it is mostly about a panel that cannot spare the capacity, not about price.
- A NACS-plug wall charger plus the Audi DC adapter. That adapter does not work on AC. See best NACS home chargers for what actually works if your wall unit has a Tesla plug.
