Maymom AC Adapter for Medela Swing Breastpump; Replacement Transformer for Medela Part # 9207043; 75% Ligher Than Medela's Original Adapter
Unlike Medela's original huge-and-large AC adapter, this one won't fell off from the outlet due to its weight. Nor will the cord connector damage itself due to heavy weight. This adapter's output is 5V, which is not exactly the same as the OEM 4.8 V.  However, our lab data and long term field test data show no noticeable difference in the suction power and the durability of the pump when using our 5V AC adapter.  You will love its light-weighted feature and 100-240V wide input feature so you can easily carry your Swing pump and use it anywhere you wish including overseas.
