Mercedes CLA EQ Charging Limitation Explained: Why Tesla Superchargers & 50 kW Chargers Won’t Work

The latest Mercedes CLA EQ is by far the best EV from a legacy OEM in 2025 but it has a Charging Limitation In this video, I explain why the CLA EQ cannot use most Tesla Superchargers and even many 50 kW and lower powered DC chargers across Europe and the US. The root cause? Mercedes’ decision to go fully 800V i.e. without a DC-DC converter. I’ll walk you through: - The technical architecture of the CLA EQ - What are charging limitations - Why 60,000+ Tesla Superchargers are incompatible - What this means for Mercedes, Ionity, and the broader EV market Maybe it’s like Apple’s Face ID or notch, controversial at first, but normal tomorrow. I’ll test drive the CLA EQ soon to see how this plays out in the real world.
