StepCharge has created a revolutionary method for charging portable devices and lithium batteries as a whole. Our technology (a charging algorithm) increases their usage time per charge and lifespan by up to 30%. That translates to 2-5 hours of extra daily usage time achieved only by different charging! We are will offer the approximately 15€ priced plug-between device in several configurations and are targeting every smart-device user. In close future we hope to expand the usage of the algorithm/software to the charging of electric cars and super-capacitors.
