When you need to add a large volume of air and only have a small pump, you can consider the use of the CO2 cartridges and the hardware that allows you to use that method of quick inflation.
In my view there are disadvantage to that method - carrying weight, cost to purchase and the proper disposal of the used cartridge. They are a compromise involving weight, cost and convenience. I carry them.
