Comparison Camry CR 7423 vs Camry CR 7422

Rated power consumed by the heater during operation.

Technically, other things being equal, a more powerful device will heat up faster and heat more greatly, but its energy consumption will also be higher. However, in fact, this parameter is of secondary importance: manufacturers select power in such a way as to provide the heating pad with the necessary performance. So paying attention to power makes sense mainly when comparing and only in cases where the differences are significant — for example, if one model consumes 100 W, and another of similar size only 60 W.
