Abstract

The user of a portable device defines the charging direction when two devices with bi-directional power transfers interfaces are interconnected. The device detects a gesture of the user and starts the power transfer to the defined direction. The user may also define the amount of charge to be transferred by the same gesture. The portable device may be operational for a longer period as long as there is another device sharing the battery charge. Embodiments of portable devices include smartphones, speakers, tablets, watches or other wearable devices.
