With the increase of electronic devices in the hands, multi-port chargers have become more and more After all, a single charger is much more bulky, portable, and cluttered than multiple chargers. There are many kinds of multi-port chargers, such as the 6-port 60W charger of Anker that I lent last time. In the near future to prepare to buy a batch of multi-port chargers, test them separately for everyone to see, today first look at a purchase of the most casual, the door MINISO casually take a multi-port charger â–¼ The charger is a plastic package and is disposable. The name is called the 5-port USB charger. There is a 3C certification mark at the bottom, and there is also a Japanese company producer â–¼On the back, told us the charger's model and parameters, the bottom of a raised slot inside the charger's power cord â–¼ look at the detailed parameters Output: 5V-5A (Max) Specifications: 9.8*6*2.6cm Weight: 153.5g â–¼ The charger is white in its entirety, and the MINISO LOGO is printed on the lower front â–¼The back of the empty, the bottom right corner has a line of numbers and letters of the code â–¼ There is a 8 word cable plug behind the charger. The output of this charger is marked on the side of the nameplate. USB*5: 5V-5A (Max) USB1:5V-2.1A USB2: 5V-1.3A USB3: 5V-2.1A USB4: 5V-1A USB5: 5V-1A The bottom part indicates that this charger is only suitable for areas under 2000m above sea level, in non-tropical climate conditions Manufacturer: Shenzhen Dibi Electronic Technology Co., Ltd. â–¼In front of the 5 USB jacks, the rated output current is also marked on the top â–¼Plug the charging line and look good â–¼5 output voltage is about 5.12V, not the five output ports are parallel, this can be a bit speechless â–¼ stepping current test, the maximum output voltage is about 4.9V, the output current can be to 4A, exactly the same, there is no line fill, it should be five USB interfaces in parallel â–¼ Charging measurement, USB1 only supports Apple 2.1A charging mode, the actual current is about 2A â–¼ USB2 can only charge ipad air2 with 0.5A speed â–¼ USB3 also supports Apple 2.1A charging mode â–¼USB4 only supports Apple 1A â–¼ USB5 also only supports Apple 1A â–¼ Hair dryer heating, you can tear off the front, back of the sticker, the front is one piece of plastic, no gap You can see the gap by tearing off the nameplate behind the â–¼ â–¼ The plastic baffle can be tilted along the gap, it can not be damaged, dismantling is destroyed â–¼Open the plastic baffle and you can see a lot of fixed glue â–¼ clean up the white plastic, you can pull out the charger's PCB, a front view, you can see a lot of capacitive inductance â–¼ Turn to the back, the traditional Schottky non-synchronous rectifier, the efficiency is average. 5 USB interfaces connected in parallel, did not see any one USB interface with identification IC, only some interfaces have identification resistors, the rest of the interface D + D - are shorted â–¼ huge aluminum passive heat sink â–¼There is also one on the other side â–¼ Look carefully at EMI circuits, with Y capacitors, inductors, fuses and other components 1, the charger can also work as a whole, small size, feel good, weight is not heavy, there are 8 words power cord, everyday out of the carrying charge is very convenient 2. The overall output of the charger is 25W, which is relatively small. The USB output port is connected in parallel, and the IC has not yet been identified. Only an individual output port has an identification resistor. The D+D-contacts of several output ports are shorted. Therefore, the daily charge must be properly selected to obtain a relatively fast charging speed 3, the overall charger seal is good, plastic PCB board is also fixed and dead, but the rectifier used Schottky asynchronous rectifier, the efficiency is relatively general, heat is not small, full load when used to pay attention to heat thank you all!
