â–¼The contents of the carton, mobile power, manual, short-term
â–¼The front of the manual is the schematic and parameters of the mobile power supply
â–¼The back is the introduction of warranty
Third, the appearance
â–¼Gift a short line of a Micro USB interface
â–¼ mobile power main body is filled with frosted plastic bag
â–¼ The upper black of the mobile power supply is the LCD display, the lower one is white, and the lower one has a Meiyi Pinyin.
â–¼ The upper part of the back is blank, below are the parameters
â–¼ The side of the mobile power supply is a grid design, indented inwards, holding hands feel a bit pickpocket
â–¼ There is a physical button at the top
The other side corresponding to the key is a lightning input interface
â–¼There are stickers at the top to seal the interface
â–¼ Tear-off stickers, dense interfaces, out1, out2, out3, Type-C in, Micro USB in, out3 is orange, support QC3.0 fast charge output
â–¼The LCD displays the power in the middle. The power indicates the input or output. The right side indicates the input or output voltage through “5V 3Aâ€, “9V 2Aâ€, and “12V 1.5Aâ€.
Fourth, test
â–¼out1 No load voltage 5.2079V
Out1 step test, maximum output 4.44V 3.2A 14.2W, no line compensation, voltage ladder drop
â–¼out2 no load voltage 5.2077V
Out2 step test, maximum output 4.52V 3.2A 14.5W, no line compensation, voltage ladder drop
Out5 5V no-load voltage 5.2122V
Out3 5V step test, the maximum output 4.75V 3.2A 15.2W, no line compensation, slightly larger output power
Out3 9V no-load voltage 9.1423V
Out3 9V step test, maximum output 8.58V 2.3A 19.7W, no line fill
12V no-load voltage 12.172V from out3
Out3 12V step test, maximum output 11.88V 1.7A 20.2W, no line fill
â–¼out1 interface does not support fast charging and cannot trigger QC or MTK
â–¼out2 does not support fast charge
â–¼out1 Charging iphone 7 plus, unable to identify Apple devices, charging current less than 1A
â–¼out2 also does not support recognition of the apple, charging current is less than 1A
â–¼out3 port can identify Apple devices, charging mode Apple 2.4A, the actual charging current of about 2A
â–¼ insert ipad pro 9.7, the same recognition, the maximum current reached 2.3A or more
â–¼ out2 also can not identify the ipad, should not support Apple recognition
The same as outout1
â–¼ Charge millet mobile power supply 2, support QC2.0, trigger 9V
â–¼ Charetech's seven-in-one mobile power supply, trigger QC3.0, voltage 6.9414V, current 2.4570A, power more than 17W
â–¼ Charetech's seven-in-one mobile power supply is charged, using a common port, the current directly to the 2.5A, voltage of about 4.8V
â–¼5V 2.4A discharge, average pressure 4.89V, released a total of 64.47Wh, calculated conversion rate of 87.12%
9V 2A discharge, 8.66V average voltage, a total of 63.46V released, calculated conversion rate of about 85.76%
â–¼12V 1.5A discharge, because there is no set stop voltage, all do not see the pressure equalization, visually measured at about 11V, released a total of 63.24Wh, calculated conversion rate of 85.46%
â–¼Micro USB interface charging, which takes 6h48min, consumes 101.96Wh, and the charging efficiency is 72.58%
â–¼Type-c interface charging, which takes 6h18min, a total of 99.13Wh, charging efficiency of 74.65%, feeling faster than the Micro USB interface, a little higher charging efficiency
â–¼lightning interface charge, current up to about 2.1A, time-consuming 9h47min, charge consumption 95.87Wh, charging efficiency is 77.19%
V. Summary
1, mobile power capacity of 20000mAh, volume and weight are considerable, the side is recessed, and there are grid-like lines, holding a general feel, mobile power front can still see, above is a black LCD screen, Below is a white plastic
2, three output and three input, really is a very powerful input and output configuration, can meet the use of multiple people, a variety of interface charging, easy to use for Android and Apple users
3, the output power of the three interfaces can also, out1 and out2 voltage is lower, and does not support the recognition of Apple, if there is Apple and QC fast charging devices can only choose to plug in the out3 interface
4, fast charging, from 0 to 100 full takes more than 6 hours, the speed can also, if you use the lightening interface charging, charging time will come more than 9 hours, this time has been very long
5, the conversion efficiency of mobile power is relatively general, about 85%, not very high
thank you all!

Transmission towers are tall buildings that support overhead power lines, usually made of steel or concrete. These transmission towers play a vital role in moving electricity from power plants to substations and ultimately to homes, businesses and other buildings. Power lines are connected to transmission towers to transmit electricity over long distances, ensuring a reliable supply of energy to different locations.
