We know that it's a little strange to have car accessories on Competitive Cyclist, but the Handpresso Auto espresso maker presents a unique case. We've always associated coffee, and especially espresso, with cycling, and this is a way to use that association to introduce a little cycling culture into your commute. So become a semi professional carista on the way to your day job. The Auto uses the 12 volt connection of a cigarette lighter to heat the water and generate an impressive 232 PSI, well beyond the usual 116 to 145 PSI necessary for making espresso. Its water reservoir is 53 milliliters. The Auto only works with pre loaded E. S. E. pods, which are little packets of espresso grounds that eliminate the mess and hassle of juggling beans, grounds, hot water, and the Auto itself.
