Question: how many watts do you need for sous vide?
Answer: No worries—the Joule boasts the highest power capacity of any of the sous vide machines at its price point (1,100 watts, while its neck-in-neck competitor, the Anova Precision Cooker, has only 900 watts). The Joule took 15 minutes to heat water to 149°, while the Anova took over 20.
