The Choetech 60W 6-Port Desktop USB Charger is retailing for US$29.99 (S$43). It is a 6-Port USB charger that includes two Qualcomm Quick Charge 2.0 ports.
Qualcomm Quick Charge 2.0 enables you to charge devices that supports Qualcomm Quick Charge up to 75% faster. Most Qualcomm Snapdragon devices like Samsung Galaxy S6/S6 Edge, Note 5/Note Edge, Nexus 6, HTC M8/M9, supports Qualcomm Quick Charge.
Choetech is so far the only company that includes two Qualcomm Quick Charge 2.0 Port into its multi-port USB charger. Aukey has one Qualcomm Quick Charge 2.0 port in its 5-Port USB charger while Anker doesn’t have any Qualcomm Quick Charge 2.0 port in its multi-port USB chargers.
Anker calls it PowerIQ, Aukey calls it AlPower and Choetech calls it Smart Ports. But they are basically the same thing because I am pretty sure they came from the same OEM source. PowerIQ/AlPower/Smart Ports intelligently detect each connected device for universal compatibility, identify the correct input current and provide the maximum possible charging speed safely.
