It’s the EV equivalent of leaving your passport at home: One absent-minded mistake and the journey is over before it begins. A stranded Mercedes owner learned this the hard way after setting out on a road trip without their charging adapter, sparking a viral debate about road trip readiness and reliability.
The clip from Haziel Lopez (@cosmictryst), which has been viewed more than 1,000 times, begins at the height of disappointment and helplessness, with what appears to be a Mercedes-Benz EQS being loaded onto a tow truck. The caption suggests the tow truck came along because the battery was tapped out: “I’m so stupid for forgetting the damn adapter, not charging before departure and planning my route along Tesla stations.”
Why The Adapter Matters
For Mercedes drivers today, the charging adapter is a lifeline on the road. All current Mercedes EVs sold in North America use the CCS1 connector standard. Yet many public fast chargers, especially Tesla’s Superchargers and Destination Chargers, use Tesla’s proprietary connector, now evolving into the NACS (North American Charging Standard). Without a certified CCS-to-NACS adapter, a Mercedes EV cannot use many of those chargers. Mercedes-Benz itself promotes its official Fast Charging Adapter to enable access to over 20,000 Tesla Superchargers.
But adapters have limits. They only work for DC fast charging and cannot convert AC to DC, so you still need the base CCS compatibility for non-Tesla stations. They can be lost, forgotten, or damaged. In Lopez’s case, the adapter was “always in my trunk,” except that day when it was left behind at a prior Tesla location.
Meanwhile, Tesla is rolling out “Magic Dock” Superchargers, where a NACS-to-CCS adapter is locked into the charger itself and can be automatically allocated. But deployment is still limited, and many Destination Chargers lack that built-in option.
Mercedes has committed to phasing in NACS ports in its electric vehicles starting in 2025, meaning the adapter step is temporary. In the interim, the adapter remains a critical piece of equipment, as vital to the road trip as your charging cable or navigation app.
The Real-World Road Trip In A Mercedes EV
On paper, Mercedes’ electric models boast a competitive range. In independent tests, some Mercedes EVs have exceeded their EPA range estimates in real-world driving conditions, per Consumer Reports. Yet real-world performance depends heavily on temperature, speed, terrain and, crucially, charger availability.
Consider a hypothetical road trip in an EQS or EQE: you start with a full charge, target fast-charging stops spaced 150-200 miles apart and expect a 20-minute top-up at each. But what happens when the only nearby charger is a Tesla station that demands an adapter you forgot? Or worse, when a CCS station is broken or out of service?
Public DC fast charging reliability is inconsistent. A study evaluated 657 CCS connectors across public stations in the San Francisco area and found that only 72.5 percent were able to charge or were currently charging at a given moment. The rest suffered from connector faults, payment failures, network issues or broken cables. That unreliability translates into idle time, stress and reduced flexibility on long drives.
Mercedes is trying to mitigate this by expanding its own charging footprint. The company plans to establish a Mercedes-Benz High-Power Charging Network with more than 400 charging hubs and over 2,500 high-power chargers in North America by the end of the decade, featuring both CCS and NACS plugs. In parallel, through its “Mercedes me Charge” platform, it already grants access to Tesla Superchargers (via adapter), integrating pricing and availability maps into its in-car navigation.
Lopez’s predicament may have gone viral, but it echoes across many EV communities. Drivers of other brands—Ford Mustang Mach-E, Volkswagen ID family, Rivian, Hyundai, and more—have posted similar stories after arriving at destinations only to realize they lacked the proper cable, adapter or backup charging plan.
Electric vehicle adoption demands a mental shift: Unlike gas cars, where you assume you’ll find a station almost anywhere, EV driving requires preplanning. Charging windows, compatibility and redundancy become part of the route strategy. Range anxiety is not just about distance since waiting time, charger uptime and availability play as big a role in driver anxiety as whether you have 10 percent or 50 percent battery left.
If Lopez’s breakdown offers a teachable moment, here’s the takeaway: Treat your charging gear as essential as your phone or money. Before departure, double check full charge levels, ensure adapters and all required cables are in the car and build redundant route plans with alternate chargers. Use tools like PlugShare or A Better Routeplanner to highlight backup stops early.
Until better charging infrastructure becomes ubiquitous, the road trip in a Mercedes EV, or any non-Tesla EV, still comes with a margin for human error. Forget your adapter once, and you might end up on a tow truck with a viral clip to your name.
