Teardown of Nubia 45W GaN Fast Charger-3cgo

Nubia’s latest 45W US charger packs a punch in a chassis no larger than Apple’s 40W unit. Clad in glossy white with the iconic red USB-C port, it’s a versatile traveler, supporting 4.1A PPS and almost every major protocol from FCP to SCP. It’s engineered to be the only "brick" you need for your phone and tablet.

Heat management is "heavy-duty" here. Nubia uses a full-potting process with white thermal glue to fill the PCBA, backed by a massive brass heat sink. This setup doesn't just keep the GaN components cool during 45W bursts; it also creates a rock-solid internal structure that’s vibration-proof and built to last.

The "brain" of the device is an Injoinic masterclass. By using the IP2075_36D (with built-in 700V GaN FET) and the IP2002TS (integrated SR), Nubia has eliminated cluttered circuitry. The IP2723T protocol IC rounds out the stack. This high level of integration is exactly how Nubia managed to cram 45W of power into such a compact form factor.

Reliability is further anchored by top-tier component choices. The charger features CapXon high-voltage filters and PolyCap solid capacitors, alongside a professional-grade NTC and fuse setup. It’s a "pro-build" through and through, offering the stability and safety usually reserved for first-party chargers.
