The expansion of DC fast-charging infrastructure is not limited to the growing number of locations and stalls. Just as important is simultaneously increasing the power output, which is crucial for replenishing range faster. The hottest segment of the US market is currently 350-500 kW, while the bottom end (up to 50 kW) has nearly stalled.
According to the Alternative Fuels Data Center (AFDC), as of January 1, 2026, there were approximately 67,916 public DC fast-charging ports (also known as stalls). The number of connectors is even higher.
*An EV charging port provides power to charge only one vehicle at a time, even though it may have multiple connectors. The number of individual connectors may be equal to or higher than the number of ports.
10K 350+ kW Chargers
The data indicates that, as of January 1, 2026, the number of charging connectors with a power output of at least 350 kW was 9,854. In recent days, this number rose to over 10,100.
Those 350+ kW chargers are the fastest-growing segment of DC fast-charging infrastructure; in one year, the number surged by 3,521, representing almost 56% year-over-year growth. For reference, the total number of ports increased 33% year over year, indicating that 350+ kW chargers are gaining market share.
The biggest player in this segment is Electrify America (roughly 4,500), followed by EVgo (roughly 3,150). Ionna has already deployed over 800 stalls (400 kW), and Mercedes-Benz has built over 300 (400 kW).
50-kW Charger Segment Barely Grows
At the other end of the market, DC chargers with power outputs of up to 50 kW saw a modest 5% year-over-year increase, reaching 5,406 at the beginning of 2026. The net increase is just 270 units (13x lower than 350+ kW chargers).
Most Common: 51-349 kW
The AFDC also provides data for other power ranges, such as 51-149 kW and 150-349 kW, but they are tricky, and we are not entirely sure how to interpret them. As a result, we calculated the number of 51-349 kW charging connectors by subtracting 50 kW and 350+ kW chargers from the total.
Assuming that the total number of DC connectors is 77,700 (the sum of CCS1, NACS, and CHAdeMO), we calculated that there are 62,449 charging connectors that offer 51-349 kW of power. This is the largest group (over an 80% share), which also expanded in 2025 by nearly 14,000 or 29%. Not strange, considering that nearly all Superchargers (roughly 36,000) fall into this range.

New Target: 350-500 kW
The infrastructure market appears to be shifting toward the 350-500 kW range, as next-generation EVs can accept higher power levels. Additionally, support for high-voltage battery systems (up to 1,000 volts) is now a must-have.
The first signs are already visible. The year 2025 has begun with a similar number of 50-kW and 350+ kW chargers (5,136 to 6,333). The year 2026 begins with almost twice the number of 350+ kW chargers than 50 kW chargers.

As soon as Tesla ditches its V3/V3.5 Superchargers (up to 325 kW) in favor of the new “true” V4 with a power output of up to 500 kW (there is one such site), the blue line will lose more than half of its growth-power, while the 350+ kW segment will skyrocket. It will truly become the fastest-growing segment.
So 83% of Electrify America are 350kW+?
That seemed too high but maybe they have upgraded more than I thought.
I haven’t looks at the ports database from the DFDC for about a year now as that data was very patchy compared to the stations database.
I think western markets (North America, Europe) are well placed for EV infrastructure with few slow DCFCs and these higher speed ones being rolled out.
Sometimes early adaptors it isn’t as peachy as we think, take China now well over 2 million DCFCs but the last breakdown shows loads of these at slower speeds.
