Protection is implemented at multiple levels and throughout the entire charging process to help measure voltage, current, and temperature accurately while protecting the battery, system, cables, and connectors.

INOV (Intelligent Negotiation for Optimum Voltage)
The version 3 is an algorithm engineered so your device can determine what power level to request at any point in time which allows for optimum power transfer while maximizing efficiency. The device can request to within 20 mV or lower the specific power needed to charge while also running advanced thermal algorithms for the case, battery, chip, and connector.

Dual Charge
