First, Huawei 10000mAh mobile power supply appearance

The white carton is packed with a black mobile power picture on the front. The above is the 10000mAh (Max 18W) Type-C version of Huawei's fast-charge mobile power supply and Huawei's logo. The product features and a CQC China Quality Certification Center certification mark are printed on the bottom.

The back of the package is marked with product features, specifications, precautions and manufacturers.

Drawer box, mobile power supply is packed in dust bag, and comes with a USB-A to USB-C charging short cable.

A list of all the items in the box.

USB-A to USB-C charging short line, can pass 3A current.

Huawei's 10000mAh fast-charge mobile power Type-C version is similar in shape to the MicroUSB version, but this is a black one. The mobile power supply case adopts two processes of bright surface treatment and matte processing. The laser HUAWEI and 10000mAh on the bright surface look very simple.

The side output connector has a dust-proof sticker.

It is equipped with a USB-A output interface, a USB-C input interface, four LED power indicator lights and a power button. The USB-A output interface uses a green rubber core and the power button has a red line decoration.

The parameter information of the product is marked on the bottom of the mobile power supply. Model: CP11QC, battery capacity: 10000mAh (typical) / 9500mAh (rated). Rated capacity is 6200mAh (5V2A), lithium ion battery rated energy: 34.49Wh. Rated input: 5V/2A, 9V/2A, rated output: 5V/2A, 9V/2A.

The corner of the mobile power supply is chamfered to enhance the feel.

The thickness of the mobile power source is equivalent to one-half the diameter of a 1-yuan coin.

The mobile power supply weighs approximately 225g.

Use ChargerLAB POWER-Z KT001 to detect the fast charge protocol of USB-A output interface, and display charging protocols such as APPLE2.4A, USB DCP, QC2.0, AFC, FCP.

The measured Mate 20 Pro is charged, the voltage is 9.03V, the current is 1.5A, and the charging power is about 13.72W, which supports fast charging.

giveMillet9 charging, voltage 9.04V, current 1.39A, charging power 12.58W, support fast charge.

Charge the Samsung S10 plus, voltage 9.03V, current 1.56A, charging power 14.15W, support fast charge.

Use Huawei charger to charge mobile power, voltage 8.83V, current 1.945A, charging power is about 17.26W, support fast charge.

Second, Huawei 10000mAh mobile power supply dismantling

Disassemble the outer casing buckle, and the foam on the outer casing is used for battery shock absorption.

The lithium ion polymer battery from Liwei New Energy has a charge limiting voltage of 4.2V and a voltage equalization of 3.63V. The single chip capacity is 10000 mAh, 36.3 Wh.

PCBA is fixed on the outer casing with screws. The front center is a power main control chip. The USB-A interface is for sinking. The battery core and PCB are soldered with nickel strips. Each nickel strip has 8 solder joints, which are very neat. The right temperature sensor is fixed with white glue to ensure a close fit to the battery.

SOUTHCHIP South core lifting and lowering chip SC1823, this is a synchronous buck charge converter with reverse boost discharge function. It integrates a power MOSFET and supports a very wide input and output voltage range for 1-4-cell Li-Ion batteries.

Nanxin SC1823 detailed specifications.

Three lithium-ion protection, the leftmost chip is the protocol chip of the USB-A interface.

Huawei FCP and QC 2.0 fast charge identification chip, from Tianyi Technology, model FP6601H. Responsible for the output protocol identification of the USB-A interface. The TV data port has a TVS for electrostatic protection to avoid failure.

Scorpio FP6601H detailed specifications.

The regulator tube of Nanjing Weimeng Electronics ME6209 series supplies power to the single chip microcomputer.

The Micro-ME6209 Series is a set of positive voltage output, three-terminal regulators that provide high current even with small input/output voltage differences. Using CMOS technology, it achieves low power consumption, high precision, and supports voltage input up to 18V.

A list of the back of the PCB.

The 10x10mm inductor has a smaller internal resistance than the common 7x7mm inductor, which reduces temperature rise and improves efficiency. The white rubber is filled around the inductor to fix and dissipate heat.

EASTSOFT Neusoft HR7P1698FGNF.

Four red LED power indicator lights, one white on the left is the fast charge indicator.

There is also a MOS tube at the USB-C interface.

The output protection circuit has a fuse.

Fengbin solid-state capacitor, 100uF 16V, for output filtering.

Charging interface close-up.

Power button.

All disassembled.

Summary of the charging head network disassembly

In terms of appearance, Huawei CP11QC two-way 18W fast charging mobile power body is light and thin, easy to carry, and the pure black appearance incorporates two styles of glossy and matte, and the simplicity is not monotonous. Equipped with mainstream USB-C fast charging interface, and comes with a USB-A to USB-C charging short cable, you can use it for charging yourself.Mobile phoneIt is very convenient to play while charging; the capacity of 10000mAh is enough to make the phone last more than twice, and daily use is not a problem.

It is found that the mobile power supply adopts Nanxin's latest lifting voltage chip SC1823 as the main control and Tianyu FP6601H as the fast charge identification of the USB-A port. A circle hole is set at the edge of PCB board to eliminate high frequency interference and avoid the interference of mobile power supply to mobile phone when used together with mobile phone and mobile phone. In addition, the other 10 × 10 inductors can effectively improve the efficiency and reduce the temperature rise, and the output uses solid-state capacitors to further reduce the ripples and ensure the stable performance.
