Kickr as a dumb trainer

Equipment
1

It’s winter. Power goes out for the afternoon. Can I use my Kickr like an old school dumb trainer? In other words: No plugging it in. No phone sync. No apps. Nothing. Just strap the bike to the thing and ride.

Can I do this without damaging the Kickr?

It won’t get damaged, but it won’t provide significant resistance without electrical power connected.
