ZhongZhengRenHe Launches a 32W 1A1C PD Charger, It Has Two Independent Output Interfaces, Which Don’t Interfere with Each Other
Household multi-port chargers often need to consider different devices, such as normal power supply of wireless chargers and screen lights. If chargers with a single output interface are used, 5V output mechanism will be triggered and locked. Therefore the two output interfaces can not charge quickly. In order to solve the problem of dual-interface output of multi-interface chargers, ZhongZhengRenHe aims at this need and launches a 32W 1A1C PD charger with two independent output interfaces, and the two interfaces don’t interfere with each other.
The appearance of ZhongZhengRenHe 32W 1A1C PD charger is white and square. A GW trademark is printed in one side. The classic 1A1C configuration can adapt to devices with different cables. The neutral appearance makes it easier to carry out OEM or ODM for customers.
As a charger with 20W + 12W two independent output circuit, the volume of ZhongZhengRenHe 1A1C PD charger is still not large. The three-dimensional size measured by a micrometer is 27.83mm * 45.72mm * 54.27mm. The weight is 78.6g. When a ZhongZhengRenHe 1A1C PD charger and an Apple 30W charger are placed side by side, the volume of ZhongZhengRenHe 1A1C PD charger is a little smaller.
Two foldable pins are used in the pin position of the back of the charger, which can be folded and align to the shell when the charger is taken outside. Thus the charger is portable. Moreover, there are small bumps on both sides, which can avoid wobbling sockets and increase stability.
Input: 100-240V 50 / 60Hz 1A Max
USB-C Output: 5V3A / 9V2.22A / 12V1.67A
USB-A Output: 5V2.4A
Combined output: 32W Max
The product has been approved by ETL and FCC as well as the sixth grade of DOE.
POWER-Z KT002 USB tester reads PDO messages of ZhongZhengRenHe 32W PD charger. It is found that it supports three fixed voltages, which are 5V3A , 9V2.22A and 12V1.67A. The maximum output power is 20W, which is consistent with the sign in the name plate.
From fast charging protocol polling, it can be seen that USB-C output interface of ZhongZhengRenHe 32W PD charger supports other protocols in addition to its own PD3.0 fast charging, such as APPLE2.4A, QC3.0, QC2.0 and AFC.
When ZhongZhengRenHe 32W 1A1C PD charger charges iPhone 12, the actual power reaches 9.14V 2.18A 19.99W. It can be equivalent to 20W PD fast charger of iPhone 12 and conforms to a performance requirement, which is 50% power is charged in 30 minutes.
The biggest advantage of ZhongZhengRenHe 32W 1A1C PD charger is using two independent interfaces. USB-C interface and USB-A interface don’t interfere with each other. The power can reach 20W and 11.97W when they charge iPhone 12 simultaneously. There is no a reduction of 5V in every interface when several interfaces are used simultaneously. Therefore it can charge two devices better.
