Macna's Dual Power technology enables you to choose between a 7,4, or 12 Volt power supply, which can be a separate battery or a direct connection to your bike. Please note batteries and chargers are NOT included). Macna offers different batteries and numerous cable options (sold separately) to provide comfortable warmth with only one power source for your entire set-up. Depending on your choice, the 7,4 or 12 Volt battery will last up to a maximum of 5:00 or 3:30 hours. A handy button indicates the battery status and current power level. There are four different levels of intensity, which can be adjusted by 20% with a single push of the button. Each level is indicated in its own colour, so you can easily spot if the heat is on. The alternative is the Macna Heated App, which allows you to connect your heated gear to your smartphone.
