An ice maker must have enough capacity, a short cycle time, appropriate ice cube dimensions and low maintenance costs for its intended use. A portable ice maker is a standalone unit that is distinct from the ice-making compartment in a freezer or home refrigerator.
An ice maker must have enough storage capacity to store the ice once it is made. Many ice-maker models have a large storage capacity that is suitable for special events, and most have excellent insulation to prevent the ice from melting. The speed at which an ice maker makes ice is also an important feature for most commercial uses.
Some popular ice makers, such as Igloo and Magi Chef, can be purchased through Walmart's online website. The Norpole and Maxx Ice ice makers can be purchased through The Home Depot website.
