Charging Performance: Power Output and Real-World Speed
Both charging stations deliver up to 22 kW of three-phase AC power, matching the onboard charger capacity of most modern EVs. That means you can add roughly 100–120 kilometers of range per hour of charging, depending on your vehicle’s efficiency and battery size. For a typical 75 kWh battery, a 22 kW wallbox can replenish from 20% to 80% in about two hours—significantly faster than the standard 7.4 kW home wallbox. For a detailed breakdown of charging times for specific battery capacities, check out our 66.5 kWh Charging Time guide.
However, the Gemini flex’s portable nature introduces a subtle trade-off: its maximum output depends entirely on the socket you connect to. While the stationary Gemini wallbox connects directly to your home’s three-phase power supply for consistent 22 kW delivery, the flex unit automatically adjusts to the available socket type. Plug into a standard Schuko outlet, and you’ll get a modest 2.3 kW—ideal for overnight top-ups. Connect to a red CEE 16A industrial socket, and you unlock the full 11 kW. For the maximum 22 kW, you’ll need a 32A CEE socket, commonly found at campsites and dedicated EV charging points.
“The Gemini flex’s intelligence lies in its automatic current adjustment—it recognizes the socket type and delivers the safest, fastest possible charge without manual configuration,” notes a go-e engineer in the product’s technical documentation. “This makes it future-proof for various charging scenarios.”
