The highest-power tier of US public charging is expanding quickly. As of Nov. 6, 2026, the third-party DCFC Tracker counts 757 locations with 6,095 DC fast stalls that have a peak rating of 400 kW or more. EVChargingStations.com reported the figures on Nov. 7. At the end of August the same tracker counted 616 sites and 4,895 stalls, so the tier added 141 sites and 1,200 stalls in about two months.

The tier is still small. EVChargingStations.com says 400 kW-plus equipment accounts for just over 5% of fast-charging locations and nearly 7.5% of fast-charging stalls. The location share matches the DCFC Tracker's national total: on Nov. 9 its home page listed 14,589 fast-charging sites, and 757 is about 5.2% of that.

Below we cover where the numbers come from, who is building these sites, and what limits the data has.

Where do these numbers come from?

Both counts come from the DCFC Tracker. The tracker says its site inventory comes from the US Department of Energy's Alternative Fuels Data Center (AFDC), the main federal station database. The AFDC's public state-count table breaks ports out by Level 1, Level 2 and DC fast, not by charger power, and on Nov. 9 it showed no as-of date. So the 400 kW cutoff, and every count in this article that depends on it, is the tracker's classification as reported by EVChargingStations.com. It is not a federal statistic.

For a sense of scale, here are the AFDC's DC fast port counts as read on Nov. 9. These cover every power level, not just 400 kW and up:

  • California: 20,508 electric station locations and 69,889 ports, including 19,717 DC fast ports
  • Colorado: 2,946 locations and 7,985 ports, including 1,723 DC fast
  • Arizona: 1,572 locations and 4,859 ports, including 1,611 DC fast
  • Alaska: 71 locations and 195 ports, including 89 DC fast

California's DC fast port count alone is more than three times the national 400 kW-plus stall count. Very-high-power hardware is growing quickly, but it is still a minority of the fast-charging fleet.

The 400 kW label describes the equipment's listed peak output. None of the sources here report how much power vehicles actually draw at these stalls.

Who is building them?

Seven networks account for most of the tier, according to EVChargingStations.com's breakdown of the Nov. 6 tracker data:

NetworkSitesStallsStalls per site
Ionna2181,7888.2
Walmart1351,1308.4
Mercedes-Benz928729.5
Tesla6273611.9
BP Pulse3954614.0
Applegreen Electric431924.5
Francis Energy471904.0

Together these seven have 636 of the 757 sites (about 84%) and 5,454 of the 6,095 stalls (about 89.5%). Ionna alone holds about 29% of the tier's stalls.

The table also shows two different ways of building. BP Pulse and Tesla put in the most stalls per site, 14.0 and 11.9. Applegreen Electric and Francis Energy average four or five stalls per site. Francis Energy has more 400 kW-plus sites than Applegreen (47 against 43) but slightly fewer stalls. Ionna, Walmart and Mercedes-Benz fall between the two groups, at roughly eight to ten stalls per site.

Tesla is fourth, which EVChargingStations.com attributes to ramping-up deployment of its V4 Superchargers. It describes these as 500 kW stalls run from a 1.2 MW cabinet that can feed up to eight dispensers.

How fast is Walmart moving?

Walmart is the network whose recent pace the sources document in the most detail. When we read the DCFC Tracker's Walmart network page on Nov. 9, it showed 139 DC fast sites with 1,160 stalls across 24 states. That is slightly more than the 135 sites and 1,130 stalls in the Nov. 6 breakdown. The network page counts all of Walmart's DC fast sites, so it may not line up exactly with the 400 kW-plus cut. On the tracker's activity figures, Walmart added 8 sites and 66 stalls in the previous seven days and 16 sites and 124 stalls in the previous 30 days.

The newest Walmart opening on the page was a Walmart Supercenter in Carmel, Indiana. It is listed as opening Nov. 7, 2026, with eight DC fast stalls and a 400 kW maximum. The page also lists a site in Hoover, Alabama, that opened Oct. 23, 2026, with eight 400 kW stalls priced at $0.49/kWh as of the Nov. 9 read.

The tracker splits Walmart's connectors about evenly: 561 stalls with NACS (the Tesla-style plug) and 563 with CCS. Those two figures add up to slightly fewer than the 1,160 total stalls listed, and the page does not explain the gap.

What does it cost?

Every price below comes from the DCFC Tracker as read on Nov. 9, 2026. Prices change often and vary by site.

  • Walmart network average: $0.46/kWh across the 139 Walmart sites with listed pricing
  • Walmart Hoover, AL: $0.49/kWh
  • National average, all tracked fast-charging sites: $0.556/kWh, up 1.1% from the prior week

The tracker shows how often prices move: 2,873 sites were repriced in the previous 30 days. Over the same period it logged 195 new site openings, 34 NACS conversions and 87 removed sites.

What It Means for Drivers

Here is what the sources say for someone deciding where to charge:

  • Coverage is growing but still thin. About one fast-charging location in 20 has 400 kW-plus hardware, by the tracker's count. Most fast-charging stops are still lower-power sites.
  • A few networks make up most of the tier. Ionna, Walmart, Mercedes-Benz and Tesla hold most of the 400 kW-plus stalls (4,526 of 6,095, about 74%). Drivers who want this hardware will mostly find it at those networks' sites.
  • Check the plug before you go. Walmart's fleet is about half NACS and half CCS, according to the tracker. A given site may not have every connector type at every stall.
  • A higher rating does not guarantee a faster session. The counts describe each stall's listed peak output. None of the sources here report delivered charging speeds.
  • Prices vary. Walmart's $0.46/kWh average was below the tracker's $0.556/kWh national figure as of Nov. 9. Thousands of sites changed prices in the past month, so check the current rate in the app or at the stall.

EVChargingStations.com says the deployment rate suggests the fourth quarter will again bring a record number of new 400 kW-plus chargers. That is an expectation, and the final count will not be known until the quarter ends.

The caveats

Three limits on the data:

  1. The 400 kW threshold and the network breakdown come from a third-party tracker, not from a government filter.
  2. The network-level figures were read on different days (Nov. 6 and Nov. 9) and do not match exactly.
  3. The AFDC table has no date on the page, so its state counts are a snapshot as of our Nov. 9 read.

The overall picture is consistent across the sources: the 400 kW-plus tier grew by about 1,200 stalls in two months, and a few large builders account for most of it.
