As far as users who start to contact high-power charging equipment are concerned, there will certainly be a variety of sizes at homeDCPort power adapter, but most smart devices are equipped with mainstream and universal USBType-CPort, can not be stored in the corner "eat ash".
Previously,ChargeLAB has launched many testers, detectors andconverterFor idle equipmentDCPower adapter, introduced a protocolconverter, can makeDCThe power adapter isType-CThe smart device of the interface is charged. Now, let's see how it works!
Unpacking Introduction
converterOn PCB board, 1 * 220uf/12V, 1 * 110uf/35V filter capacitor and inductance wrapped with insulating rubber sleeveMlc capacitor, port bus and other devices are clear and clear as a whole.
At the same time,A protocol master chip is welded on the back of the PCB board to control the conversion.
Viewed from the side, weldedDCThe female seat has all copper nickel plated pins inside, which is more resistant to oxidation and wear, and its specification isDC5520。
Two USB's are welded on the other end of PCB boardType-CThe rubber core of mother seat and mother mouth is black.
At the same time,The USB ports are equipped with a power on LED indicator, which displays a blue light effect after connection and charging.
DC power adapter will be used for power supply and USB detectionType-CThe charging protocol of the port, so as to match the output device according to the specific protocol, and obtain a better fast charging experience;The charging protocols of the two ports measured are consistent, so only one of them is described.
usePOWER-ZMeasured by KM003C testerType-CPorts support FCPAFC、QC3.1、SFCP、PD3.0、Charging protocols such as PPS, QC4+, DCP and Apple 2.4A.
PDO Message,Type-C port has three fixed voltage gears of 5V/3A, 9V/3A, 12V/2.5A, and one PPS voltage gear of 3.3-11V/3A.
Charging test
The maximum output power of the chip on the converter is30WAccording to the minimum efficiency, the adapter needs more than 35.294W, and the input voltage is recommended to be a charger within the 12V-28V range, that is, a power supply with more than 12V3A and more than 36W power.
When the input power is lower than the output power, the charging equipment is fully loaded30WUnder power condition, if the adapter just provides30W, will cause the adapter to trigger overcurrent, and the user needs to pay attention to the power supply specification of the device.
After connecting the adapter through the DC power adapter, use a hundred watt C to C charging wire to connect the Type-C port of the adapter and the Type-C charging port of the laptopPOWER-ZKM003C tester shows that the input power of the pen terminal is 11.09V 2.42A 26.84W.
Similarly, use a hundred watt C to C charging wire to connect the Type-C port of the adapter and the Type-C charging port of the panelPOWER-ZThe KM003C tester shows that the input power at the panel end is 11.09V 2.43A 26.98W.
Connect the Type-C port of the adapter and the Type-C charging port of the iPhone 15 Pro phone with the 100W C to C charging wirePOWER-ZKM003C tester shows that the input power of mobile phone terminal is 9.06V 2.63A 23.84W.
Connect the Type-C port of the adapter and the Type-C charging port of Huawei Mate 60 Pro mobile phone with a 100W C to C charging wirePOWER-ZKM003C tester shows that the input power of mobile phone terminal is 9.07V 1.89A 17.14W.
Connect the Type-C port of the adapter and the Type-C charging port of the Xiaomi 13 Ultra mobile phone with the 100W C to C charging wire. The actual measurement POWER-Z KM003C tester shows that the input power of the mobile phone terminal is 8.60V 2.85A 24.52W.
Connect the Type-C port of the adapter and the Type-C charging port of the iQOO 12 Pro mobile phone with the 100W C to C charging wire. The measured POWER-Z KM003C tester shows that the input power of the mobile phone terminal is 9.08V 1.92A 17.38W.
Connect the Type-C port of the adapter and the Type-C charging port of the Meizu 20 PRO mobile phone with the 100W C to C charging wire. The actual measurement POWER-Z KM003C tester shows that the input power of the mobile phone terminal is 8.64V 3.31A 28.61W.
Use high specification C to C charging wire to connect Type-C port of adapter to charge two mobile phones. The measured input power of Xiaomi 13 Ultra mobile phone terminal is 7.09W, and that of Huawei Mate 60 Pro mobile phone terminal is 9.35W.
Through actual measurement verification,Type-C interface supports single port blind plug, and the maximum charging power is30W;When two ports output at the same time, the total output power is 5V3.4A.
Summary of charging head network
Based on the test results above the charging head network, the protocol adapter can inherit the charging protocol adapted to the DC power supply. At the same time, the output power of the USB Type-C port of the adapter can provide the same power as the original adapter, or reach the upper limit of the port, and meet the charging requirements of two devices. Users can reuse the DC power adapters such as routers, desk lamps, and audio adapters when they are idle,Compatible with mainstream charging mode, continue to emit light and heat.
