Compact Powerhouse: Huawei 66W Gallium Nitride Charger Steals the Spotlight

At the Huawei Mate 80 series and All-Scenario New Product Launch, the bundled 66W "Rock Candy" Universal GaN Charger drew significant attention alongside the high-end flagship smartphones. Designed to meet the fast-charging needs of the Mate 80 standard edition, this "all-rounder" accessory is also compatible with multiple brands.

Encased in a flame-retardant white PC plastic shell with a high-gloss finish, the device boasts a minimalist and sharp aesthetic. While many users are accustomed to the standard charger 20w for basic needs, this compact unit offers a massive leap in power density. The body features the "66W" and "HUAWEI SuperCharge" logos on the side, with detailed parameters on the input end, a fixed Chinese standard plug, and a single USB-C port branded with the Huawei logo.

Core Parameters and Compatibility

The model HW-110600C05 is designed for maximum compatibility across various voltage scenarios and has passed CCC certification. In an era where a basic charge wall unit might be bulky, this charger measures only 48.11mm × 31.01mm × 31.03mm and weighs approximately 70g. When compared to Apple’s 67W charger, its size advantage is striking. Despite its small stature—not much larger than a typical charger 20w—it supports a vast array of protocols including UFCS, FCP, SCP, QC2.0/5, PD3.0, PPS, and DCP. This allows it to seamlessly power smartphones, laptops, and tablets. Finding a versatile charge wall adapter that covers both PDO and UFCS voltage stages is essential for modern multi-device users.

Internal Teardown: Structural Design and Components

To explore its internal quality, we conducted a professional teardown. After cutting open the top shell, the internal PCBA module was found to be reinforced with white potting glue to enhance stability and drop resistance. While a budget charger 20w often lacks sophisticated thermal management, this 66W module (44.44mm × 26.64mm × 26.89mm) features thermal conductive glue for sealing and a rear assembly of insulating plates and heat sinks. The structure is meticulously organized: the input end includes an NTC thermistor and safety X-capacitors, while the side houses a planar transformer with a plastic-shielded magnetic core. This level of engineering ensures that even when plugged into a charge wall for extended periods, the heat remains well-regulated.

Output Details and Final Verdict

The output stage features a dedicated USB-C daughterboard and two solid-state filtering capacitors to ensure a stable current. In conclusion, the Huawei 66W "Rock Candy" GaN charger transcends the limitations of a standard charger 20w by providing high-wattage output in an ultra-portable form factor. It combines Huawei’s signature minimalist design with robust internal construction and comprehensive protocol support. Whether you are looking for a primary charge wall solution for the Mate 80 series or a reliable third-party power brick, this charger delivers a safe and premium fast-charging experience
