The RH-228 user interface consists of a panel keypad and LED display in which the user switches between modes and controls the vacuum pressure. Model RH-338 is capable of single pumping and has three modes - stimulate mode, massage mode and expression mode. The RH-338 user interface consists of a panel keypad and LCD display in which the user switches between modes and controls the vacuum pressure.

The RH-228 is externally powered by 5Vdc USB. The RH-338 is internally powered by 3.7Vdc lithium battery or externally powered by 5Vdc USB. The external adapter also charges the battery.

Both models of the Electric breast pump are provided with a breast shield, cylinder cap, cylinder, valve, vacuum tubing, feeding bottle, and a nipple kit. Model RH-338 also includes a massage cushion and a dust cap. The user-contacting materials are limited to polypropylene (breast shield) and silicone (massage cushion).
