A typical Christmas inflatable can use anywhere between 1 and 5 amps of power, depending on the size and complexity of the inflatable. For example, a small inflatable that measures 2 feet by 2 feet will likely only require 1 to 2 amps of power, while a larger inflatable that measures 10 feet by 10 feet may require up to 5 amps of power. Additionally, the duration of use will also affect the amount of amps needed; if an inflatable is only used for a short period of time, then it will require less power than if it were used for several hours.
