Runtime = capacity (Wh) × 0.85 ÷ 50 W
For a full workday you need about 480 Wh (400 Wh of energy plus inverter losses). Running other devices at the same time? Add them in the runtime calculator.
Tips to run your laptop longer
- Charging via USB-C PD directly from the power station skips the inverter and the laptop brick, often 15–25% more runtime.
- Gaming laptops can draw 150–250 W under load. Enter your charger's wattage in the calculator.
- Add a monitor (~25–40 W) and router (~15 W) for a realistic remote-work setup.
