The :wave unit has a built-in battery and can also be powered by an external power source. The battery is charged when the :wave is connected to an external power source.
There are multiple ways to power your :wave:
|LEMO port (9-36V DC)||Mains power adaptor with LEMO compatible connection.|
|Micro USB||Micro USB 2.0 charger connected to power source.|
You can reduce the amount of power the :wave uses by turning off the Wi-Fi feature. If you need to have Wi-Fi turned on, there is a stealth mode which will turn off Wi-Fi automatically if the external power is lost.
