This question depends on which gloves you are referring to. The heated gloves with the connectors that we've had since we started in 2015 do not work independently. They require you to own one of our 12v down jackets that have the glove connectors and you must have a 12v battery. Without the 12v down jacket and the 12v battery, the gloves will not work.
However, we launched a heated glove on Kickstarter in Feb 2018 that will work independently with out a jacket. It will have its own battery allowing you to freely use the gloves with any other winter gear.
