inflatable birthday cake

Small cake balloons are usually made of latex. Larger yard inflatables are typically manufactured from polyester or polyurethane-coated polyester, and some designs use fabric-based materials.

Small cake balloons can be inflated with air or helium. Larger yard inflatables use built-in blower fans that plug into a standard power outlet; batteries are not commonly used for these larger decorations.

Many inflatable cakes include built-in LED lighting, from white illumination to multicolor or rotating LED modules. Product listings sometimes specify the number of LEDs (for example, 2–6) and note that the lights activate when the unit is plugged in.

Large outdoor inflatables commonly include ground stakes, tethering ropes or clips, and sometimes a weighted base or sandbag to help keep the decoration secure.

Outdoor inflatable cakes are often described as weatherproof or weather resistant and are made from durable polyester or polyurethane-coated polyester to resist outdoor wear and fading.

Blowers and lights are powered by plugging into a standard electrical outlet. Many inflatables include a UL- or ETL-listed adapter or transformer and come with the necessary power cords for the built-in fan and lights.
