FAQ

Is the widget free?

Yes. The widget is free to embed on any site. It loads from EVCostHub servers and stays current with the latest electricity rates and vehicle data.

Can I change the default state or model?

Yes. Use the state and model dropdowns above to set defaults. The embed code updates automatically with your chosen parameters as URL query strings.

Does the widget work on mobile?

Yes. The widget is fully responsive and adapts to any iframe width. On narrow viewports the form and results stack vertically.

Can I change the widget height?

Yes. Adjust the height attribute in the iframe tag. A height of 600px works well for most layouts. The widget also sends a postMessage to the parent page so you can auto-resize if needed.
