Huawei will be officially launched on January 8, the main compact portable CP07 mini mobile power charger head network to get the product in advance, and released the open-box "the whole network starting: Huawei 6700mAh mini mobile power out of the box tour."
Here I come from you to disassemble the evaluation to readers:
White embossed carton packaging, elegant and clean, it seems very taste and meaning printed on the front with product images, product names and HUAWEI Logo features and products with hot silver printing, it is very on the grade.
Product specifications are relatively simple, the capacity of 6700mAh, input and output 5V, 2A, support for small current discharge. Input Interface: Micro USB, Output: USB Type-A, black, white, pink three colors, Black Edition. This section of the product called 'Standard Edition' may mean 5V low-voltage output, look forward to follow-up with fast charge 'enhanced version.' There is also worth noting that Huawei uses environmentally friendly soy ink Printing product packaging, reflecting the attention of a major brand of environmental protection and due responsibility.
Mobile power black body, most of the area by the finer ring wrapped, warm and delicate touch non-slip, a short cover with a matte black skin-friendly coating, such as fine velvet-like texture, enhance the visual effect. Micro USB, USB Type-A I / O and power button are distributed from left to right as shown in the picture above. The supplied dark gray Micro USB cable is of high quality with barcode sticker.
Cover the side of the distribution of 4 white LED power indicator light, moderate brightness, yet eye-catching yet.
24.3Wh, from the appearance of the product and the nominal capacity can guess the internal is composed of two 18650 batteries, with two 18650 battery size.Product bottom nameplate printed with the same package serial number,
Compared with a cigarette box than the size (Tips: smoking is harmful to health), very good grip.
Insert a LED USB lamp (only for demonstration, other brands, separately) immediately turned flashlight.
Huawei recommended to increase the integrated flashlight this function, or a single head lamp accessories is not bad yo ~ Charging test:
iPad mini 3, full speed, drop 10W, ChargerLab Power-Z KM001 tester shows its support Apple 2.4A protocol.
The Samsung note 3 Neo handset, which had a more charged head, also reached a full speed of 8.6 W. EBD Stepping Test:
The voltage is maintained above 5V in the current of 2.2A, the output of 0.7A appears a smaller step line compensation, when the voltage exceeds 2.3A falls below 5V, the maximum discharge current reached 2.4A, at this time the voltage is 4.77V, the maximum power of 11.4W. Recharge test:
Use a wired patch USB plug, 10W input power.
Dismantling:
The bottom cover is ultrasonically welded and the remaining three sides are tightly snapped in. White silicone rubber is used inside the housing to hold the cell.
2 pink LG AB F1L batteries in parallel, the single capacity of 3350mAh, high-end mobile power standard. High temperature insulating tape below the battery negative leads and NTC thermistor.
NTC thermistor is used in soft silicone wire, non-low-end enameled wire, high temperature insulation better performance. The motherboard uses two screws to the shell.
The positive battery end of the shell paper to do to strengthen the insulation, the shell there are cells for the isolation limit, to prevent the drop impact may occur displacement. Positive battery nickel plate with the motherboard for the spot welding connection, the negative thick silicone wire tin weld.
Micro USB, USB Type-A sockets are of good quality with through-hole soldering firmly in place. The Logo on the USB Type-A socket is CZT.
The negative electrode spot welding nickel chip also uses a layer of sponge tape to do the buffer protection.
Front of the black double-sided PCB motherboard, Huawei used a full set of British-core program, IP5209T + IP3005A.
The back of the distribution of closed high-power inductors and LED resistance capacitance of the original.Copper traces the use of expensive gold plating process, for enhancing the conductivity, enhanced heat dissipation and other aspects have a positive effect.
IP5209T QFN24 package, different from the previous IP5209, more with a suffix 'T', temporarily unable to find its details, it is speculated that may increase the small current discharge function IP5209 improved.
Huawei CP07 (6700mAh) mini mobile power with small current discharge function, without this feature mobile power is not able to charge the Bluetooth headset, sports bracelet and other small products. Most mobile power supply on the market did not take into account the small current output scenarios , When the output current is small to a certain extent that (cell phone) is already full, turn off the output. The following is the IP5209 public information, has been widely used in Nanfu Xiaojia, Meizu M8E and other big mobile power.
P5209: A multi-purpose power management SOC with integrated boost converter, Li-Ion battery charge management, and battery level indication, providing a complete power solution for mobile power applications Powered by switching charging technology delivering 2.4A current to 97 %. Built-in IC temperature and input voltage intelligently adjusts the charge current. Requires only one inductor for buck and boost functions. The DC-DC converter operates at 1.00MHz and supports low cost current and capacitance. The IP5209 synchronous boost system provides 2.4A output current, the conversion efficiency up to 96%. No-load, automatically go to sleep, quiescent current down to 100uA. Built-in 14bitADC, accurate measurement of battery voltage and current, ADC data can be accessed through I2C. IP5209 built- Can accurately obtain battery power information.Customizable battery power curve, can accurately display the battery power, support for 3/4/5 LED power display and lighting functions.
IP3005A is British lithium core IC dedicated protection IC, built-in MOS, line simplicity.
Take a look at the shell:
ABS + PC material, taking into account the strength and toughness, strong and shock resistant. Inside the shell 'CP07' product model mark.
The power button, which is mounted on a semi-levitation bracket, provides a moderate force feedback for pressing, giving it a soft, lightweight feel.
The LED power indicator has a black, soft silicone frame that is optically isolated to prevent stringing.
Die is more sophisticated.
The outer surface of the LED light-transmitting hole on the outer shell is also covered with a layer of white soft paper for reducing the light intensity of the LED and reducing the dazzling discomfort. The details are well done.
Bottom cover is the first use of ultrasonic welding and then use the glue card nameplate sealing process. Dismantling family portrait:
Huawei CP07 (6700mAh) mini mobile power is the same machine with a thousand full screen Huawei enjoy 7S with Chang launched together, the positioning is not very high-end, conventional 5V low-voltage output, wins in the compact and portable, smaller than it lipstick charging treasure due to battery life Serious deficiencies, often tasteless food discarded feel regrettable, and more than 1 million mAh and too heavy, sometimes carrying it seems very cumbersome.
2 18650 batteries Huawei CP07 (6700mAh) is just right, you can gain a more appropriate balance of volume and weight and battery life, to meet most of the power needs.
Manufacturing process is, as always, the style of excellence manufacturers, with the appropriate sales price, is very worth considering.
