What charge port does the Hyundai Ioniq 9 use?

NACS (North American Charging Standard, Tesla's connector, standardized as SAE J3400) for both AC and DC. No adapter is needed for the port it ships with.

How fast does the Hyundai Ioniq 9 charge at home?

GarageDex could not confirm a published onboard AC kW figure for the 2025 to 2026 model year from the manufacturer's own page - check your window sticker or owner's manual for the exact number.

How fast does the Hyundai Ioniq 9 charge at a DC fast charger?

Up to 350 kW at a compatible DC fast charger, tapering as the battery fills - most DC sessions are planned to about 80%, not 100%, because the last 20% charges much slower.

Does the Hyundai Ioniq 9 need an adapter for Tesla Superchargers?

No. It has a NACS port, so it plugs into Tesla Superchargers directly; it needs an adapter only for CCS1 fast chargers and J1772 Level 2 stations.

NACS adapter and Tesla Superchargers for the Hyundai Ioniq 9

The 2025 to 2026 Hyundai Ioniq 9 has a NACS port, so it plugs into a Tesla Supercharger directly where its maker has access (below).

Tesla Supercharger access: “Starting today, U.S. owners of the current Hyundai KONA Electric, IONIQ Electric hatchback, IONIQ 5, and IONIQ 6 models equipped with a Combined Charging System (CCS) port gain access to 20,000 Tesla Superchargers in the United States using a North American Charging Standard (NACS) adapter.” Hyundai Newsroom: Hyundai Owners Gain Access to U.S. Tesla Superchargers With Complimentary NACS Adapters (2025-03-25)
Official adapter: “The adapters are complimentary for eligible owners and lessees that purchased their Hyundai EV on or before January 31, 2025.” “Even though MSRP is $250, the dealer’s selling price and final cost of the NACS adapter is completely up to the dealer as they have 100% discretion.” MyHyundai Owners: NACS Adapter Giveaway FAQs

Which Level 2 charger do you need?

A home Level 2 charger is sold by its amperage (32A, 40A, 48A...), but your car only ever charges at the lower of two numbers: the charger's rated output and your car's own onboard AC charger limit. Installing a 48A/11.5 kW charger on a car with a 7.7 kW onboard charger does not speed anything up - the car simply will not draw more than it can accept. On any DC fast charger, the same idea applies to the whole session: charging is fastest at a low state of charge and tapers hard above roughly 80%, which is why route-charging stops are usually planned to 80%, not 100% (per the U.S. Department of Transportation's EV charging speeds guide). Match a home charger's amperage to your car's onboard AC rating from the table above, with a little headroom for future EVs in the household, rather than buying the biggest unit available.
