Can a Mercedes-Benz CLA with EQ Technology 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 CLA with EQ Technology has a built-in NACS port, so no adapter is needed. Plug in, open the Tesla app, pick the stall, and start.
At the stall: the 2027 charge port is passenger-side rear. Native NACS but rear-right, so back in and prefer an end stall. US cars from spring 2026 have a 400 V converter and work on V3; Mercedes has not published the 400 V rate. 320 kW only on 800 V / V4.
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.
- First Mercedes with a native NACS port (plus separate J1772 AC port). 800 V only at launch: the first US demo cars (late 2025) could NOT charge on 400 V V3 Superchargers. US customer cars from spring 2026 include a factory DC converter and work on V3; full 320 kW only on V4/1,000 V. Ships with a CCS1-to-NACS adapter.
- 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.
