1. If you are going to purchase an air pump for your inflatable, make sure that the power of the air pump is appropriate for the inflatable's size.
2. Trampoline parts such as trampoline enclosures and trampoline covers are great trampoline accessories. Use hand trucks to move your backyard trampolines or castle bounce houses to where they need to be.
3. Deflators are not necessary for the function of an inflatable, but they do greatly cut down on deflation time, and are certainly handy to have.
4. Patch kits are good to keep on hand if you have a bounce house. Bounce house repair kits cover minor puncture holes and extend the life of your inflatable.
5. Stakes and hooks help to secure large inflatable bounce houses, and are definitely worth having. If your bounce house model does not include them, bounce house stakes and hooks are available for separate purchase.
