Can a Mercedes-Benz EQS sedan / EQS SUV use Tesla Superchargers?
Yes. Mercedes-Benz vehicles have had official Supercharger access since February 2025. You charge at any Supercharger marked “open to non-Tesla” using the Tesla app.
The 2027 EQS sedan / EQS SUV has a CCS1 port. At NACS stalls you need a NACS-to-CCS1 DC adapter: the Mercedes-Benz NACS to CCS1 Adapter ($185). $185 at dealers from Q1 2025. Included with MY2026 CCS1 EVs; earlier owners buy it. Adapter details. Magic Dock sites (green) need no adapter at all.
At the stall: the 2027 charge port is passenger-side rear. Expect about 180 kW at a V3 stall (the car is rated 200 kW; the 500 A cable and adapter cap it). Back in, end stall preferred. 200 kW rated; a 500 A adapter at V3 voltage gives roughly 180-200 kW, and some owners report far less when the pack is cold.
How to charge: download the Tesla app, choose “Charge Your Non-Tesla”, add a payment card, pick the site and stall number, plug in, then tap Start. Older V2 Superchargers (grey on the map) only work with Teslas.
- CLA: verify the build has the 400 V converter before relying on V3 stalls.
- Adapter is $40 cheaper than GM's; only Mercedes-certified adapter is warranty-covered.
Good to know about Superchargers
- Only Superchargers marked 'open to NACS partners' (V3, V3+ and V4 stalls with the Tesla app 'Charge Your Non-Tesla' flow) are usable by non-Tesla cars. Older V2 stalls are Tesla-only. A small number of V3 'Magic Dock' sites have a built-in CCS1 adapter and work for any CCS1 car regardless of brand agreement.
- V3 and V3+ dispensers run roughly 400-500 V and top out at 250 kW. 800 V-class cars (Hyundai/Kia/Genesis E-GMP, Porsche Taycan/Macan, Audi Q6/A6 e-tron, Lucid, Mercedes CLA, Cadillac Escalade IQ/GMC Hummer/Silverado EV in some modes) charge slower there unless they have an on-board boost converter. V4 cabinets (500 kW, up to 1,000 V) started going live in September 2025 and remove that penalty.
- V3 cables are short and sized for Tesla's rear-left port. Cars with a front or passenger-side port often have to park nose-in or across two stalls. V4 posts have longer cables.
- Adapters: only a DC 'NACS-to-CCS1' adapter approved by the vehicle maker is covered by that maker's warranty; Tesla's app will still let unapproved adapters charge, but the OEM may deny warranty claims. AC 'J1772-to-NACS' adapters are a different product and are irrelevant for Superchargers.
