Charging Head Network Deep Review No. 3227

Introduction

As retractable cables continue to gain popularity in the 3C digital market, many manufacturers are launching related products, including various retractable charging cables and car chargers. As a brand focused on consumer electronics accessories, XINLEWEI has always centered around core categories such as charging devices and data cables, emphasizing practicality and high cost-performance ratio, aiming to solve the convenience pain points in users’ daily power usage scenarios. Recently, the brand has launched a new product – the 240W C-C fast charging retractable data cable, which easily meets users’ daily storage and efficient power supply needs with its two core advantages: high power fast charging and dual retractable design.

Let’s take a look at whether the XINLEWEI 240W C-C fast charging retractable data cable is really useful.

Unboxing Introduction

The XINLEWEI 240W C-C fast charging retractable data cable features a round design, with a smooth overall style and wires protruding from both ends.

The XINLEWEI 240W C-C fast charging retractable data cable uses a black matte shell, with a DC pattern around the middle, printed with the “240W” power label.

The side of the shell features a black lacquer finish, providing a rich sense of layering.

The measured width of the shell is approximately 60.18mm.

The thickness is approximately 21.38mm.

Dual Retractable Cable

Unlike single-end retractable or fixed-length cables, the dual retractable cable design allows for dual lines to be pulled out with a single pull, effectively doubling the output length. When not in use, both ends can be fully retracted to the shortest state, keeping the cable compact and preventing the traditional “knotting and tangling” problem, making it easy to fit into pockets, backpacks, or storage boxes, especially suitable for daily commuting and travel scenarios.

The compact size makes it portable, and after retracting the cable, it can easily fit into a pants pocket.

Both ends are printed with the “240W” label.

The terminals are equipped with built-in E-Marker chips,which can intelligently match the current and voltage according to the terminal device,protecting battery health and ensuring safer charging.

The XINLEWEI 240W C-C fast charging retractable data cable uses a silicone flat wire, which is resistant to bending and combines flexibility with durability.

Using the POWER-Z KM003C tester, the E-Marker chip information of the XINLEWEI 240W C-C fast charging retractable data cable shows the scheme as: Undefined(0x0000), indicating that this cable supports USB4 2.0 data transmission capabilities and 50V 5A 240W EPR power supply capabilities.

The length of the XINLEWEI 240W C-C fast charging retractable data cable is approximately 93cm.

The thickness of the XINLEWEI 240W C-C fast charging retractable data cable is approximately 1.8mm, making it slim yet flexible.

The 3-meter long XINLEWEI 240W C-C fast charging retractable data cable weighs approximately 50.9g.

It is compact enough to fit in an adult’s palm and can be easily held with one hand.

Charging Test

How does the actual charging power performance of the XINLEWEI 240W C-C fast charging retractable data cable compare to the manufacturer’s description?

Charging Head Network usedChargerLAB POWER-Z P240 to conduct a real test of 48V 5A 240W power supply/load. The XINLEWEI 240W C-C fast charging retractable data cable can easily provide high power supply.

Using an Apple 140W charger + XINLEWEI 240W C-C fast charging retractable data cable to charge a MacBook Pro M4 Pro laptop, the actual input power at the laptop’s input port was 27.41V 4.74A 130W.

Using an Apple 140W charger + XINLEWEI 240W C-C fast charging retractable data cable to charge an iPhone 16 Pro, the actual input power at the phone’s input port was 14.51V 1.67A 24.25W, handshake PD protocol.

Charging the iPhone 16 Plus, the actual input power at the phone’s input port was 14.74V 1.92A 28.36W, handshake PD protocol.

Charging the Xiaomi 15 Pro with the Xiaomi Little Pudding 120W charger, the actual input power at the phone’s input port was 19.13V 3.92A 75.08W, handshake Xiaomi proprietary protocol.

Charging the OPPO Find X7 Ultra with the OPPO Little Square Bottle 100W charger, the actual input power at the phone’s input port was 8.35V 4.98A 41.58W, handshake SVOOC proprietary protocol.

Charging the vivo X200 Pro with the original 120W charger, the actual input power at the phone’s input port was 8.42V 4.86A 40.96W, handshake SVOOC proprietary protocol.

Charging the Huawei Mate 70 Pro+ with the original 100W charger, the actual input power at the phone’s input port was 8.42V 4.75A 40W, handshake UFCS protocol.

Voltage Drop Test

The voltage drop test is an important factor in measuring cable quality. During daily use for charging a phone, the voltage and current are output from the charger to one end of the cable, then transmitted to the other end of the cable to the phone, which involves voltage drop data.

Connecting the cable ends to the power instrument and load instrument, we tested the input and output voltages of the cable at different levels, calculating the difference, which is the voltage drop value; a total of 16 levels were tested, with the results shown above.

Drawing a bar chart, it is clear that the maximum voltage drop difference occurs at the 48V/28V/20V 5A level with 0.68V, while the minimum voltage drop difference occurs at the 5V/9V/12V/15V/20V/28V 1A level with 0.13V; with a 3A current for the voltage drop test, the difference is around 0.40-0.41V; with a 1A current for the voltage drop test, the difference is generally around 0.13-0.14V.

Data Transmission Test

In addition to supporting 240W fast charging,the XINLEWEI data cable also supports USB2.0 transmission speeds. Let’s test this.

The hard drive used for testing is the Zhi Tai Ling Pioneer Edition mobile solid-state drive, supporting 20Gbps high-speed transmission, while the laptop is the Huawei MateBook X Pro 2024, which is equipped with 2 Thunderbolt 4 ports, and the cable used isthe XINLEWEI 240W C-C fast charging retractable data cable.

On the Windows platform, using CrystalDiskMark 8.0 software, the hard drive read speed reached 38.14MB/s, and the write speed was approximately 38.08MB/s,indicating that the XINLEWEI 240W C-C fast charging retractable data cable can meet daily small file reading and transmission needs.

Additionally, copying a test file of approximately 14.7GB from the local computer to the hard drive, the write speed remained stable at around 38.1MB/s throughout.
