there are two types of electric breast pumps, hospital-grade and personal-use. hospital-grade pumps are larger and intended for multiple users. personal-use pumps are generally intended for one user. electric breast pumps are powered by a motor which supplies suction through plastic tubing to a horn that fits over the nipple. the portions of the pump that come into direct contact with the expressed milk must be sterilized to prevent contamination. this style provides more suction, making pumping significantly faster, and allows users to pump both their breasts at the same time. electric breast pumps are larger than manual ones, but portable models are available (e.g. in a backpack or shoulder bag). some models include battery packs or built-in batteries to enable portable operation of the pump. some electric pumps allow multi-user operation, but recommend an accessory kit for each user to maintain cleanliness.
