Ok, so I've been pumping for almost 5 months now with my rented Medela symphony and have been very happy with it. At the end of this month I will need to go on a business trip and I think it would be very helpful if I could have a battery pack to use since I think I'll be pumping in the bathroom at least a little. Not ideal, I know, but depending on how long travel time is I'll have to pump in an airport, but thankfully not on a plane.
Anyway, I though I could go online and buy some sort of battery pack for this thing, but it doesn't seem like it. Do you either have a model with batteries or one without? would something like this:
work with a symphony or no?
