The Power Egg Inflator by Island Hopper is designed to inflate any Island Hopper inflatable product. Simply attach the hose into your Halkey Roberts valve with the adapter, turn it on, and watch your Island Hopper inflate. This inflator is powered by a 110v wall plugin only. The product will work with any brand of water sports product with the Halkey Roberts valve or universal inflatable boat valve. Ships and sold separately. We don’t suggest using it on drop stitch water platforms because it can only reach a maximum PSI of around 2PSI. We suggest the Auto Set PSI 15 pump for drop stitch platforms. We suggest letting this inflator cool off after every 15 minutes of use, especially on large water trampolines. Please read the owner’s manual before using the Power Egg.
