The description does not indicate voltage, and this is a 12V transformer. My pump requires the 9V. Really wish I'd been able to tell the difference from the product description before paying for the expedited shipping!

This is not for the 2008 or later Pump in Style models. Make sure you double check your pump and make sure whether you need the 9 V or 12 V.
