The Handpresso is literally the size of a deodorant can and can be carried everywhere you go. It uses no electricity and all you really need is hot water and your favorite coffee (powder or pod). The Handpresso has a pump integrated into its design with an in-built pressure gauge. All you do is pump it up till the gauge reads 16 bar pressure. Fill the reservoir with hot water, and top-off the coffee cartridge either with fresh coffee grounds or your standard E.S.E Pod. Once you’ve put the cartridge back into the Handpresso, simply lock it in place before hitting the pressure release button. The pressure pushes the water through the coffee and out of the nozzle, giving you one cup of freshly brewed espresso, made right in front of your eyes!
