Both eteeController and eteeTracker have their own battery and they can be charged independently or through eteeController, thus requiring only 2 cables at minimum.

If the tracker is low on battery, it will be powered by eteeController until eteeController runs out of battery too. 


eteeControllerとeteeTrackerは両方とも独自のバッテリーを備えており、個別にまたは eteeControllerを通じて充電できるため、必要なケーブルは少なくとも 2 本だけです。
