Well the latest invention is top secret but you can do it at any cheap harware sale. Go to costco buy a compressor that hooks to your battery then go to a harware store or traveling tool sale buy some air storage tanks then put the hose on and regulator voila you have a kite pump. I know everything points to not use compressed air but if you can regulate and be careful of the amount of pressure not volume its such a handy thing to have. upon experimentation if you wanna go solo with this then a 10gallon at 125+psi will fill most midsized kites. pumping sucks and so does all the battery powered stuff compressed air is quick and reliable. give it a try let us know if there are any inventions on the horizon for kiting.
