There are a few different types of ice makers that you can buy. Which one you choose depends on where you wish to install your ice maker, the type of ice you want, and how long/often you plan to use the product. There are built-in/under-counter ice makers, and freestanding ice makers, in addition to portable ice makers and ice maker kits. Each option has its own advantages, but one of the biggest benefits of having a portable ice maker is that a water line is not required. You can add your own fresh water to the machine manually, letting you take it just about anywhere.   While built-in and freestanding ice makers can make much more ice than a portable one, anywhere from 20 to over 100 lbs. in just over 24 hours, they lack the fully finished look and portable design that a portable/countertop ice machine has. The choice of which type you decide to purchase is up to you and your specific needs, but having some starter information before you buy a new ice maker can make all the difference in helping you make the best decision.
