IntelligentPowerDiffusion(IPD) is Spigen PowerArc’s charging technology which evenly distributes power between multiple ports. When one port is in use, IPD allows for maximum power output to one port. When two ports are in use, IPD ensures power is
distributed evenly between the ports while minimizing the waste of wattage.

IPD Technology allows Spigen PowerArc’s products to be designed more compact than other chargers. Without IPD, chargers can be twice as heavy and large due to large power output requiring much bigger chipsets and heatsinks.
