Introduction

As a consumer electronics brand under the Xiaomi ecosystem, MIIIW has recently launched the CB510 Pro Dual-Head Super Charging Cable to meet the growing demand for dual-device charging solutions. This cable supports a maximum charging power of 100W and allows fast charging for two devices simultaneously. Depending on the input power, it intelligently allocates output with configurations such as 70W+30W, 45W+20W, and 25W+20W.

The cable features MIIIW's self-developed IDC2.0 smart conversion module, which integrates a built-in protocol conversion chip. This enables compatibility with a wide range of fast-charging protocols from Apple, Xiaomi, OPPO, vivo, and more. Notably, it allows standard chargers to support Xiaomi’s proprietary fast charging, delivering up to 90W, effectively revitalizing older chargers. The CB510 Pro is not only versatile but also highly practical. Let’s take a closer look at its design and build quality.

Product Appearance

The front of the box features the MIIIW logo, the product name, and a visual of the cable.

Printed on the side are two main selling points: simultaneous dual-device fast charging and up to 100W MAX charging power.

The back of the box displays spec info, manufacturer information, and a power distribution chart.

The two output cables follow different power distribution strategies based on the input power:

• At 100W input: up to 70W Max + 30W Max
• At 65W input: up to 45W Max + 20W Max
• At 45W input: up to 25W Max + 20W Max
• At 30W input: up to 10W Max + 10W Max
• At 20W or below, power is distributed evenly between the two outputs

The model is iCB1013Y. The cable is constructed with TPE material and produced by Beijing MIIIW Technology Co., Ltd.

Only the charging cable is included in the package.

It features a braided design with a black-and-white alternating pattern along the sheath. Both the USB-C connectors and the splitter are housed in a silver-gray metal casing, giving the overall design a refined and aesthetically pleasing appearance.

The input connector features a sandblasted finish with smoothly curved edges on both sides. Additionally, the front of the USB-C input connector housing is printed with "IN," a triangle symbol indicating the input current direction, and the "100W MAX" power rating.

The two output cable connectors are marked with OUT1, OUT2, 100W MAX, and a triangle symbol to help users easily distinguish between them.

The USB-C male output connectors feature orange plastic casings for enhanced protection.

The splitter housing features the same design, with MIIIW and CB510 Pro printed on the front.

The cable body is tightly braided, smooth overall, and free of any burrs, reflecting high-quality craftsmanship.

The length of the cable is 137 cm (53.94 inches).

The diameter is about 3.87 mm (0.15 inches).

ChargerLAB POWER-Z KM003C shows it has an E-marker chip, supports 20V5A, and USB 2.0.

The cable enables standard chargers to be converted to support Xiaomi’s proprietary 90W MAX fast charging protocol. For instance, testing with an Apple 140W charger confirmed that the output supports Xiaomi’s 90W proprietary fast charging.

It supports one Xiaomi proprietary fast charging fixed PDO of 5-20V4.5A.

The test results for the other output cable are the same.

The PDO reports are also the same.

Using an Apple 140W charger with the MIIIW CB510 Pro 100W Two-in-One Supercharging Cable to charge a MacBook Pro delivers a power of about 88W, successfully enabling 100W PD fast charging.

Paired with the SHARGE 140W charger, charging the Xiaomi 15 Pro successfully triggers Xiaomi’s 90W proprietary fast charging.

When switching to an Apple 96W charger, charging the Xiaomi 15 Pro can still trigger Xiaomi’s 90W proprietary fast charging.

Using an Apple 96W charger with the cable to charge both the MacBook Pro and Xiaomi 14 Ultra delivers charging powers of 63W and 24.56W respectively, enabling simultaneous fast charging for two devices.

Charging the Xiaomi 15 Pro and Xiaomi 14 Ultra simultaneously, the power is 28.65W and 37W, respectively.

Teardown

Next, let's take it apart to see its design and build quality.

Cut open the input connector. The interior is filled with orange and black plastic.

After removing the internal plastic, one side of the internal PCB reveals an E-Marker chip.

The other side is soldered with three wire cores.

The E-Marker chip is from Injoinic. It is a USB Type-C cable electronic marker chip that supports the USB Type-C 2.1 standard and PD 3.1 specification, providing a complete E-Marker chip solution for USB-C cables. It has passed the USB-IF PD 3.1 certification with TID: 7106 and supports full-function USB 3.2 cable applications. Model is IP2133.

It integrates a VCONN diode and an Ra resistor, supports data programming and write protection, as well as data locking. It operates within a voltage range of 2.7 to 5.75V, with VCONN and CC pins rated for 28V withstand voltage. The chip comes in DFN 2x2-6L and DFN 2x2-8L packages, making it suitable for USB-C passive cables, EPR, and full-function cable applications.
