Belkin 70W GaN Desktop Charger: In-Depth Review of a Lightweight Fast Charging Choice

Famous peripheral brand Belkin has recently launched a 70W gallium nitride (GaN) charger, which can be regarded as the "youth simplified version" of its previous 100W model. While appropriately reducing performance, it has achieved a significant reduction in body size and weight. With a weight of only 105g and a detachable pin design, this USB C wall charger accurately meets users' core needs for portable fast charging devices. Equipped with a 2C1A multi-interface combination and supported by GaN technology, it balances compatibility and output efficiency. Below, we will comprehensively interpret this "powerful small cube" from unboxing to disassembly, and also explore its practicality as a compact desk charging station.

1. Unboxing Overview: Details Reflect Brand Texture

The outer packaging of this desktop charger continues Belkin's family-style design. The front clearly marks the brand logo, product name, appearance diagram and core selling points, allowing users to intuitively understand the core product information. The back of the packaging focuses on the interface power distribution scheme diagram, supplemented by detailed descriptions of the product's core features, with a clear and easy-to-understand information structure.

After opening the package, the internal accessories are complete, including the charger main unit, product user manual, quality assurance certificate and list of toxic and hazardous substances, fully covering the user's needs for use and after-sales service.

2. Appearance & Details: Compact, Round and Portable

This 70W GaN USB C wall charger inherits the classic design language of Belkin's fast charging series. The body surface is treated with a frosted process, which not only feels delicate but also effectively resists fingerprint residue. The corners of the body adopt a large arc transition design, making the overall shape compact and round with a comfortable grip.

One side of the body is prominently printed with the Belkin brand logo and "70W" power marking for users to quickly identify the product specifications; the back details the complete parameter information of the charger to meet the viewing needs of professional users. It is worth mentioning that the product has passed CCC mandatory certification and Level VI energy efficiency certification, providing reliable guarantees in both safety and energy saving.

In terms of interface design, the output end of the charger is equipped with 2 USB-C interfaces and 1 USB-A interface, forming a practical 2C1A combination. The power parameters for single-port and multi-port output are clearly marked next to the interfaces, allowing users to quickly match devices without consulting the manual, greatly improving the convenience of use. As a versatile desktop charger, it can easily adapt to various charging scenarios.

In terms of portability design, the charger adopts a semi-encapsulated folded pin that meets the new national standard. The pin can be folded during storage, effectively saving backpack space and reducing the risk of accidental damage during carrying. More notably, the shell of its input end supports the assembly and replacement of pins. Users can replace the corresponding pins according to the socket standards of different countries and regions to achieve global compatibility, which greatly expands the applicable scenarios of the product, making it an excellent choice for a desk charging station in both home and office environments.

3. Core Parameters: Multi-Scenario Compatibility

The product model is WCH018yz, with specific parameters as follows:

Input specification: 100-240V~50/60Hz 2A, supporting global wide-voltage input and adapting to power grid standards in different regions.

Single-port output capability:

USB-C1/C2 interfaces (supporting PDO and PPS protocols): Under PDO mode, it provides 5V3A, 9V3A, 12V3A, 15V3A, 20V3.5A gears; under PPS mode, it supports 5-11V3A, 5-21V3.5A gears. The maximum single-port output power can reach 70W, which can meet the fast charging needs of mainstream laptops. This USB C wall charger performs exceptionally well in high-power output scenarios.

USB-A interface: Supports 5V3A, 9V2A, 12V1.5A, 10V2.25A gears, with a maximum output power of 22.5W, adapting to the fast charging needs of Android phones and other devices.

Multi-port simultaneous output strategy:

Two-port output (C1+C2): 45W+25W, total power 70W, which can fast charge laptops and tablets at the same time, making it a practical desk charging station for multi-device users.

Two-port output (C1/C2+USB-A): 45W+22.5W, total power 67.5W, suitable for simultaneous charging of laptops and phones.

Three-port output (C1+C2+USB-A): 45W+12W+12W, total power 69W, which can meet the power supply needs of three devices at the same time, fully demonstrating the advantages of this desktop charger in multi-device compatibility.

4. Test Data: Compact Size with Outstanding Performance

Through actual measurement, this charger has excellent body size performance: length 54.07mm, width 38.53mm, thickness 42.87mm. Compared with Apple's 70W GaN charger, it has an obvious volume advantage. Combined with the 105g lightweight design, it is completely burden-free to carry whether for daily commuting or long-distance travel. As a USB C wall charger, its compact size makes it easy to store and carry.

To verify its compatibility, we used the ChargerLAB POWER-Z KM003C tester to measure the protocol support of each interface:

USB-C1 port: Fully supports UFCS integrated fast charging, QC3+/5, FCP, SCP, AFC, PD3.0, PPS, DCP, SAM 2A and Apple 2.4A protocols. The PDO message shows that it has five fixed voltage gears and two PPS voltage gears. The UFCS protocol supports three gears: 3.4-5.5V3A, 5.5-11V3A, 11-21V3A, with full compatibility. This makes the desktop charger suitable for most mainstream electronic devices.

USB-C2 port: The protocol support range is exactly the same as that of the USB-C1 port, and the PDO message parameters are also the same. The two C ports can be used interchangeably without deliberately distinguishing between primary and secondary ports.

USB-A port: Supports QC3.0, FCP, SCP, AFC, SFCP, DCP, SAM 2A and Apple 2.4A protocols, covering the charging needs of mainstream Android and Apple devices, with extremely strong practicality. This versatility further enhances the value of the desk charging station.

5. Disassembly Exploration: Solid and Reliable Internal Materials

To further understand its internal design and materials, we disassembled the charger. After opening the input end shell, it was found that the pins are fixed by plastic fixing plates and screws, with in-place insulation treatment, which effectively improves the safety of use. As a high-quality USB C wall charger, its internal structure design is very rigorous.

The internal connecting wires and the space between the core module and the shell are all treated with glue, which not only enhances the structural stability but also achieves good heat dissipation and shock resistance effects, reflecting Belkin's quality control standards in details. Combined with its adopted GaN technology scheme, while reducing the body size, it also ensures the balance between charging efficiency and heat dissipation performance, making it a typical representative of "small size with great energy" among desktop chargers and an ideal choice for a high-performance desk charging station.
