Peltier War! - Cascading Vs Double Power

While I was doing the Peltier Cascading video, I wondered whether it would be better to run one peltier with 10 amps or two peltiers with 5 amps each. I figured the single unit would be better but I was shocked to see the results. Check it out! This video shows two TEC1-12706 units compared to a single TEC1-12710 unit.
