Do you know how many quick charge standards in cell phone?How to choose the right fast charger for your cell phone?

What’s PD?What’s qc 3.0?Why qc 4.0 not popular now?

I want to explain all.

    What is the difference among QC1.0,QC2.0 & QC3.0?

    QC,means quick charger.Nowadys,technology is prevailing and QC1.0 was improved to QC3.0.However,many of us doesn’t know exactly the difference among this three type of products.

    Actually,here is a picture show something different among them.

      Here we can see that the amount of current offered by Quick Charge has remained relatively consistent, but increasing the charging voltage has helped allow for faster charge times. With 3.0, the range of voltages will allow for fast charging and better efficiency.And we can know it easily that the QC3.0 will support q faster charging speed.
      What’s more,LDNIO nowadays has improved all the QC2.0 products to the QC3.0 one.

    Qualcomm have updated its quick charge into qc 4.0.
    But why most charger supplier don’t supply it?
    Because only tens series mobile phone support qc 4.0.Even the mobile phone support qc4.0,qc 3.0 charger still can be used.
    So in market,you can see many qc 3.0 charger,just a littile qc 3.0.

    What is qualcomm 3.0?
    Quick Charge 3.0 is engineered to refuel devices up to four times faster than conventional charging. It is designed to charge twice as fast as Quick Charge 1.0 and to be 38 percent more efficient than Quick Charge 2.0. Now consumers can spend even less time charging, and can grab and go more quickly.

    How does qualcomm 3.0 work?
    Quick Charge 3.0 employs Intelligent Negotiation for Optimum Voltage (INOV), an algorithm which allows your portable device to determine what power level to request at any point in time, enabling optimum power transfer while maximizing efficiency. It also supports wider voltage options, allowing a mobile device to dynamically adjust to the ideal voltage level supported by that specific device. Specifically, Quick Charge 3.0 offers a more granular range of voltages: 200mV increments, from 3.6V to 20V. That way your phone can target one of dozens of power levels.

    What is PD?
    PD is power delivery.The USB Power Delivery Specification enables the maximum functionality of USB by providing more flexible power delivery along with data over a single cable. Its aim is to operate with and build on the existing USB ecosystem.

  6. ldnio says:

    PD have what features?
    USB Power Delivery offers the following features:
    Increased power levels from existing USB standards up to 100W.
    Power direction is no longer fixed. This enables the product with the power (Host or Peripheral) to provide the power.
    Optimize power management across multiple peripherals by allowing each device to take only the power it requires, and to get more power when required for a given application.
    Intelligent and flexible system level management of power via optional hub communication with the PC.
    Allows low power cases such as headsets to negotiate for only the power they require.

    how many quick charge standards in cell phone?
    qualcomm 1.0,qualcomm 2.0,qualcomm 3.0.qualcomm 4.0 is all the stantard of fast charge.
