  • Qualcomm Quick Charge 3.0 - instead of pre-set voltage limits, QC 3.0 intelligently identifies the power needed and adjusts the charge rate to that which is most efficient. That means the device can charge faster (when it’s able to), and there’s up to 38% less power loss when charging.

  • Four Times Faster than conventional charger - using QC 3.0 allows your device to achieve 80% battery for only 30-35 minutes which is two times faster than the original Quick Charge standard. There is no need to wait for more than an hour just to charge your phone. [Read more in the description below]

  • Intelligent Negotiation for Optimum Voltage (INOV) - for optimum transfer as it maximizes the efficiency by letting the device detect the exact power level needed at any given time which allows your device to accumulate the required power levels.

  • Two USB Ports - allow you to simultaneously charge two devices at maximum speed.

  • The Perfect Travel Companion - the lightweight and compact size (plus all international voltage (AC110-240V) make it great cell phone charger for any your travel. Output: DC5V=2.4 amp (max); DC9V=1.5 amp (max); DC12V=1 amp (max)


  • USB charger for iphone, mobile phones and other 5V USB devices.

    How Does Qualcomm Quick Charge 3.0 Work?

    To help speed up the charge rate the voltage and amperage need to be adjusted. Since they’re both interconnected, and because there’s the component of resistance in there too, the ratios must be monitored and adjusted as the battery is “filled” with its charge.
    Think of this as filling a pitcher of water. You can fill it with a trickle of water and you won’t risk spilling a single drop – but it will take a long time. You can fill it with a firehose, but after a split-second burst there will be water everywhere, and after the hose is shut off, you’ll likely see that hardly any water stayed in the pitcher. Instead, as you fill a pitcher, you probably start out fairly slowly until the flow starts going, then gradually open the spigot all the way. As the water level starts getting to the top, you back off the flow rate to make sure you don’t overfill the pitcher and make a mess, eventually filling the last little bit with a trickle.

    That’s exactly how QC 3.0 works!

    A 3.0 charger “talks” with the device to coordinate the charge rate, and adjusts different voltage settings. All this results in “minimized losses, increased efficiency, and improved thermal performance.”

    Why Charge Up to 80% Battery Life?

    Smartphone batteries charge in two different phases:

    • The first phase is from 0-80% and this phase absorbs huge amount of power at once.
    • From 81-100%, the battery has to be careful of the power level it absorbs.

    QC 3.0 increases the process during the first phase four times faster than conventional chargers. Because of its algorithm, it can determine the power level it has to absorb when the phase changes.
