Many domestic accessory manufacturers have successively launched different types of screen display data lines, which can display basic information such as power and current. The POWER-Z 240W screen display data line launched by ChargeLAB has a separate screen display body, which can read more advanced information such as voltage, current, protocol, temperature and data type.The charging head network will conduct a detailed analysis and measurement of this data line, and let's take a look at the specific performance!
Product Introduction
As usual, look at the packaging first.
The front of the box is stillPOWER-ZStyle.The front is only marked with LOGO.
Open the package, including data cable * 1 and instruction manual * 1.
The data cable is made of black C to C wire. The cable body is relatively soft, and it is fixed with black cloth Velcro.
The digital display screen is designed with transparent fog surface, which can vaguely see the internal circuit board structure;There is a 0.96-inch color screen in the middle, which can display voltage, current, power, current direction and other information.
Relevant parameter information is printed on the back: model: AK001, range: 0-50V, 0-5A;In addition, it has round click operation keys, which can have different pictures and functions through click, long press and double click operations, and the screen can be flipped or not displayed.
When it is powered on, the primary display interface includes charging voltage, charging current and charging power.
The peer displays on the secondary interface are wire specification/current direction, signal voltage/capacity, data port voltage/temperature, and data port voltage/timer.
Click the button on the back to switch the interface of displaying information, with display interfaces such as detailed display, brief display, brand display only and information screen.
In actual measurement, long press the back button to flip the screen.
Both ends of the wire material are equipped with extended injection molded sub end housings, and the terminals are alloy interfaces, which are wear-resistant and resistant to plugging;The terminal and wire adopt the integrated injection molding process, and the soft material is resistant to bending and has a longer service life.
The POWER-Z KM003C tester could not identify the E-Marker chip information, but it was found that there was a chip inside after disassembly.
The length of POWER-Z screen display data line is about 158cm.
The main body of the display screen is about 6.5cm long.
Product evaluation
The test of wire rod is mainly reflected in two aspects: functional test and the quality test of wire rod itself.The former mainly tests which functions the wire supports and whether it supports fast charging, data transmission and video transmission;The latter mainly tests the internal quality of the wire rod, involving specific test items such as voltage drop. Next, we will see the test results of POWER-Z 240W PD3.1 digital display data line functions.
Quick charge
Since it is wire material, charging must be tested. Let's test it.
Use 140W charger and POWER-Z wire to charge the Red Devil 7S mobile phone. The digital display screen shows that the charging voltage is 17.46V, the current is 5.06A, and the power is about 88.33W.
Use Apple 67W GaN charger and POWER-Z wire to charge the iPad Air 5. The digital display meter shows that the charging voltage is 14.79V, the current is 2.21A, and the power is about 32.7W.
Using Apple 140W GaN chargerDigital display data cableConnect the Apple MacBook Pro 16 M1 Max 2021 model, and the charging power is 19.92V 4.67A 93.12W at this time, which can trigger the fast charging of 100 watts and can pass 5A current.
In order to test the higher charging power, the two ends of the wire are connected to the power supply and load respectively. It can be seen that the charging voltage is 28V and the current is 4.971A.
On the load side, we can see that the transmitted power is 136.8W, and the power displayed on the digital display screen is 127.91W.
Summary
According to the actual measurement, the new POWER-Z digital display data line can achieve 140W power transmission through the load test equipment. With its own digital display screen, it is very good for ordinary users to clearly see the power when charging.
data transmission
After watching the fast charging, let's see if the wire supports data transmission.
The two ends of the wire are respectively the USB-C interface of MacBook Pro 16 M1 Max 2021 and Thunderbolt 3 hard disk box. The hard disk box is loaded with Samsung 970EVO solid state disk. At this time, the hard disk has been successfully read on the computer screen, indicating that the wire supports data transmission.Use Disk Speed Test to test the transmission speed. The measured write speed is about 36.3MB/s, and the read speed is about 38.6MB/s, which conforms to the USB2.0 data transmission standard.
Summary
The POWER-Z 240W PD3.1 digital display data cable supports not only fast charging, but also USB2.0 standard data transmission. This transmission speed is very good for daily use to transfer some small files.
video transmission
Fast charging, data transmission, the last item, check whether the wire supports video transmission.
Connect the two ends of the wire to the USB-C interface of the iPad Pro and the USB-C display, and the display cannot be lit when measured;"No USB-C signal from your device" can also be seen on the display, indicating that the wire does not support video transmission.
Summary
According to the actual measurement, the POWER-Z 240W PD3.1 digital display data cable does not support video transmission. For users, the cable can meet their needs for fast charging and data transmission.
Pressure drop test
Voltage drop test is an important factor to measure the quality of wire rod. In daily use, it charges the mobile phone. The voltage and current are output to one end of the wire rod through the charger, and then transmitted to the other end of the wire rod to the mobile phone. The transmission of both ends of the wire rod involves voltage drop data.
Connect the two ends of the wire to the power supply instrument and the load instrument respectively. This time, the charge voltage and output voltage of the wire at different gears are tested respectively, and the travel value is calculated. The difference is the value of the voltage drop;A total of 13 gears were tested this time, and the test results are as follows.
The histogram is drawn. It can be clearly seen that the gear with the largest difference in pressure drop is 0.64V of 20V5A, and the gear with the lowest difference is 0.14V of 20V1A and 28V1A.
summary
POWER-Z 240W PD3.1 digital display data cable is made of pure black C to C wire, and is fixed with black cloth Velcro;The main body of the display screen is designed with a transparent fog surface, which can see the internal circuit board structure. By clicking, long pressing and double clicking the back button, different picture information is displayed. Compared with the previous generation of wire materials, the flexibility and feel are better. The 1.5M length is also more suitable for daily use, which is convenient for storage.
In terms of performance, POWER-Z 240W PD3.1 digital display data cable supports 20V5A 100W charging power and can transmit 5A charging current. In addition, the cable also supports USB2.0 data transmission, but it does not support video signal transmission.
In terms of practicality, its own digital display screen is the biggest highlight of this line. The 100W fast charging power is also the highest charging specification under the widespread popularity of USB PDs at present. With the USB2.0 data transmission speed, it is very good for users' daily use;It is a good choice for users who want to know the charging information but do not have professional instruments to test. Even for Xiaobai, it is easy to understand.
