IntelliChip is a smart feature in TOPGREENER USB devices that recognizes the power needs of each individual device and delivers the maximum power each device will allow. The intelliChip reads when a device is fully charged and stops delivering power, thus safeguarding it from overcharging . As a result, the device is also protected from overheating. Overcharging or overheating a device can decrease its lifespan and capacity, and cause damaging effects on a battery. Both USB A and USB C ports in TOPGREEENER devices have this technology.
