Recently questions have arisen about pumps in differnet countries. This information was also discussed on the net a few months ago. Options for mothers leaving the USA would be: 1. Some of the newer pumps with plugs on the Market have Switching Power Supplies (SPS) These power supplies automaticly sense the voltage and hertz and adjust themselves automaticly. You can determine this by calling the manufacturer or looking at the bottom of the Pump. The pumps usually will list the voltage and hertz or the range. You want to see a 110V-240V, 50hz-60Hz designation. But call the manufacturer to be sure. 2. Some other Purchasable pumps use separate transformers. By having the correct transformer you can adapt to the local country. Manufacturers that are international in nature will have several transformers available. Call the manufacturer for more information 3. Some pumps work on Batteries. Those that use commercial available batteries such as AA can be purcahsed vitually anywhere in the world in major cities. If it is a rechargable system check with the manufacturer for more exact information. Rechargable systems may have more exacting requirements for electrical input. 4. Local Availability of Pumps is another option. However, the types of pumps, accessory kits, efficiency cost and other factors may be unknown in the particular area where the mother may be traveling or moving to. Also the instant availability of pumps should be examined. If the mother needs a pump she should not assume 24 hour availability in other countries. After a long trip it may be difficult to quickly locate a pump. Some pump companies are international in nature and a call to the head office could give you more information.
