The images of the Moto Mod were shared by hellomotoHK (spotted by TechDroider) and resemble what was showcased at the MWC 2017 expo. At the event, Motorola said that the Moto Power Pack when snapped on the back of the Moto Z series smartphones, will add up to 50 percent more power. It will do so by analyzing the amount of battery left in the smartphone and juice up the battery life only when it s needed. The Power Pack Mod was to launch in March with a price of $50 (Rs 3,200 approximately) but it was shifted to later this year.

Motorola already has two Mods meant for providing extra battery life, the Incipio offGRID Power Pack and the Mophie Juice Pack. The Incipio offGRID Power Pack comes with a 2,220mAh battery aimed to provide battery life of up to 20 hours. This Mod also comes with a smart efficiency mode which automatically charges the smartphone at the right time. The Mophie Juice Pack comes with a larger 3,000mAh battery and is said to provide 60 percent more battery life. This Mod also features a status indicator light and a USB Type-C port.
