No motor, no battery, no cord. It is one piece of food grade silicone: squeeze the body, seat the funnel, and the suction holds it there while it fills. Playtex build it for the side the baby is not on, so the let down that would otherwise go into a breast pad is collected instead.

The body is graduated up the side, to 120 in milliliters and to 4 in ounces, so you can read what you have without pouring it out first. It stands on a wide suction base, which is the part that stops the whole thing going over on a night table, and an oval lid closes it for the trip to the fridge. Playtex describe the kit as the pump with that lid and that base, and those are the parts shown here. There is no valve and no membrane inside, so washing it is the smooth silicone surface and nothing else, which is the difference that matters at two in the morning.

Playtex publish it as food grade silicone, gentle, and safe for both mother and baby. It is a product for the mother rather than the baby, so it carries no infant age grade. When it is time to feed, pour what you collected into a VentAire Complete Tummy Comfort bottle.
