Charge of the latest smartphone is instant, too! "The latest high speed Charge standard of USB"

Even as for tablet, the PC, it is high speed Charge by the latest USB USB!

Speaking of Charge, both smartphone and game are USB. In the times when we can charge large apparatus.

The scene that did Charge using USB mainly on digital product equipped with battery including smartphone and game apparatus spread in our surroundings.
Charge using USB was limited to small devices such as smartphone until now.
However, we add to conventional Charge standard, and "it is higher-speed, and it is more possible for new Charge standard corresponding to the high output", and devices corresponding to that increase, too.
By new Charge standard, note PC and tablet which we were not able to charge came to be able to be charged from USB until now.

Charge standard of the latest USB becoming more and more convenient. What kind of type will there be?

It has a lot on each Charge standard more.

  • Power Delivery
  • Quick Charge
  • Conventional standard

In the first place what kind of state is "Charge?"

At first, we will know basic way of thinking of Charge.

Charge to apparatus equipped with battery is similar to accumulating water to glass with syringe as image.

Battery charger electricity battery

Charge to apparatus equipped with battery is similar to accumulating water to glass with syringe as image.

  • ・Syringe is battery charger
  • ・Water is electricity
  • ・Glass is apparatus equipped with battery.
    How long you can accumulate water to glass early that is it is point whether it can supply electricity.
Power and "pushed" flow, given "quantity" "pushing" are points!Power and "pushed" flow, given "quantity" "pushing" are points!

Primary key word to understand "basics of Charge"

  • V VoltageV Voltage

    V Voltage

    It is power that is going to carry away power = electricity pushing syringe.
    Unit expresses in voltages (V).

  • A electric currentA electric current

    A electric current

    It is quantity of flow = flowing electricity of water pushed out of syringe.
    Unit expresses in amperes (A).

  • W electricity

    It is electric quantity to be supplied to quantity = battery of water which collected to glass.
    Unit expresses in watts (W).

"How long" can performance of battery charger supply electricity?

Charge performance expresses in units of watt (W).
Watt (W) can demand thickness = electric current (A) and syringe of needle of syringe by multiplication of outthrust = Voltage (V).

Charge performance (W) = electric current (A) X Voltage (V)

We know performance in this.We know performance in this.

Past Charge method and new Charge method.

  • Charge method of conventional standard

    Conventionally, in standard, we were doing stitch of syringe thickly to accumulate water to glass early. In other words, it increased electric quantity = electric currents which by making exit big, flowed, and electricity collected early.

    1A battery charger 1A 2.4 times 2.4A battery charger 2.4A including IPhone attachment

    We can apply electric current of 2.4 times with battery charger of 1A and battery charger of 2.4A, and Charge speed becomes early only by just that much, too.

  • Charge method of new standard

    Outthrust became able to make water strong at the same time to do needle of syringe in new high speed Charge standard thickly to save water to glass earlier.

    1A battery charger 1A X SV=5W 20 times 20V PowerDelivery battery charger 5A *20V = 100W including SV IPhone attachment

    In other words, we make exit big (electric current) and by pushing by stronger power (Voltage), hasten Charge speed.

It has a lot on each Charge standard more.

  • Power Delivery
  • Quick Charge
  • Conventional standard

New standard PowerDelivery (PD) which has begun to be adopted in note PC and tablet

In late years Charge standard of USB that supporting device increases to is USB PowerDelivery (power delivery as follows "USB PD"). We can use USB PD with "apparatus corresponding to USB PD with connector of USB Type-C or Lightning connector".

iPhone XS, iPhone XR, XPERIA XZ3, Galaxy Note9, most of latest models of smartphone including Pixcel3 support USB PD.
USB PD supports the output which is more expensive than standard conventionally of up to 100W and begins to be adopted in not only smartphone but also note PC or tablet.

PC tabletPC tablet

As USB PD is high output of up to 100W, we will have power of 20 times in comparison with Charge apparatus of the 5W (5V/1A) output attached to iPhone and iPad.
Speed of Charge being quick in the output feeding being big by just that much.
For example, in PD18W of ELECOM, quantity of Charge as of 30 minutes is about 2.3 times of Contents!
It is Features that there is difference by start-up. USB PD is very powerful standard.

As for the selection of USB battery charger for PD, "maximum output" is point

Device communicates with the battery charger side in USB PD and, in the range of to maximum output on the battery charger side, chooses Voltage, electric current, the output which are most suitable for device automatically.
Battery charger with "maximum output" output which is most suitable for each device or more is necessary.

When we charge plural devices at the same time, the number of total W of all devices is necessary.

We can perform data communication let alone power supply with one USB Type-C cable at the same time, too. It is simple and can do wiring because we can charge note PC while projecting Video when we connect outside display to note PC with USB Type-C cable.

QuickCharge which is carried mainly on smartphone of the Android deployment

Standard that high speed can charge smartphone and tablet

Quick Charge is high-speed Charge standard that American Qualcom (Qualcomm) company adopted mainly on smartphone of the Android deployment develops and provides. Corresponding to "there is USB Type-C or Micro B female connector Quick Charge can use with apparatus".

If it is QuickCharge3.0, Charge of up to 60W is possible

Some versions are in Quick Charge and realize up to 27% of Charge speed in comparison with QuickCharge2.0 with it is QuickCharge3.0 used most widely. Because there is lower compatibility with 2.0, QuickCharge3.0 can use product for QuickCharge3.0 for product for 2.0.

Qualcomn quick charge 3.0 Qualcomn quick charge 2.0

In QuickCharge3.0, technique called "Intelligent Negotiation for Optimum Voltage (INOV)" is adopted. This automatically adjusts both Voltage and electric current in the most suitable level depending on device to perform hi-charging most efficiently.

USB 2.0, conventional standard including USB BC1.2

USB 2.0, conventional standard including USB BC1.2

USB is adopted as standard to connect peripheral device to PC from the 1990s. It was main role at first to make data movement between peripheral device and PC such as mouse or keyboard. As it is the same connector, and feeding was possible, as Specifications of USB, we come to gradually carry role of Charge. USB 2.0 is announced in 2000, and USB3.0 is announced in 2008. Opportunities of Charge using USB increased, and, in USB3.0, quantities of biggest data transmission increased, and ability for feeding was raised to 900mA from 500mA (millimeters ampere), too. Furthermore, USBBC1.2 which raised ability for feeding becomes able to feed to up to 1,500mA. [email protected] (3,000mA) is added with TypeC terminal added by USB3.1.
