Though being small and portable, this giant balloon inflator will effortlessly inflate your large balloons in minutes. The electrical inflator has three different sized nozzles which you can accordingly choose based on the balloon you are inflating. Instructions on use will be enclosed with the boxed electrical inflator. The inflator can also be used to inflate other inflatables other than large balloons. When inflating the following balloons: 18” Round, 2ft Round, 5.5ft Long, we would recommend that you begin inflating the balloon with your mouth or a hand-pump - this will allow pressure to expand the surface of the balloon. The inflator is a high-pressure pump and therefore would struggle to inflate a small sized balloon. By inflating the balloon beforehand, will resolve this issue.
