Bought for travel. No water reservoir. Smaller and more portable. Pour a cup of water in. This is how much coffee fills the cup. I found the coffee was hotter and slightly more flavorful than the larger version I have at home. Las Vegas hotel rooms do not have coffee makers. They expect you to get dressed, go to the casino Starbucks, and stand in line for your morning coffee. Best decision we made was to take our own pods and coffee maker. My wife uses it for hot tea.
