How big is the inflatable castle suitable for playing? Is it dangerous to suddenly lose power?

The inflatable castle is suitable for children aged 3- 12.

The air tightness of the inflatable castle has a great influence on safety, and a well-made inflatable castle will not collapse soon even if there is a power failure. A better inflatable castle takes about 3-5 minutes from power failure to collapse. Operators should use this time to evacuate children as soon as possible. Don't panic.
