Let me introduce this heater from 3 aspects:

The material

This Dew Heater main fabric is made of Neoprene. It's different from general cloth. More introduction about this fabric: Neoprene is water-resistant, exhibits good chemical stability, and maintains flexibility when subject to a wide range of temperatures. ... Given its incredible durability, neoprene is used in the creation of laptop sleeves, orthopedic braces, swimwear, wetsuits, camera bags..etc. After comparing it with other Dew bands, we found such material is good at keeping the heat inside, that's to say, it will be more power-efficient for us.

The Power

High: 7.5W Medium: 3.75W Low: 1.85W Compatible with most power banks, 5V. You can power it with your general power bank with a 5V output, USB-A connector.
