OK, I followed that link to the amazon page and now I see the device. And I see that the draw at 9 volts is indeed 2.5 amps. Now given that most of that load is from the thermo-electric cooler, that should certainly be very tolerant of noise and ripple on the power source. Do you have that device and it's power supply already? If so, check the specifications of the power supply, you may be able to run the fans from that.
