I travel more often than I like, taking with me the tools of my trade; a smartphone phone and tablet. I top up their charge every evening to ensure these devices are always working at peak performance.
Today I am looking closely at a 45w wall charger from Ugreen. This device is small, light, and powerful. Can it get the job done? Read on and find out.
The Ugreen Nexode Mini charger’s case is composed of black plastic. It is 2 inches tall with a width and depth of 1.5 inches.
A pair of back-mounted AC prongs fold neatly into the charger when not in use. Two USB-C ports are fitted to the front of this device.
This charger is compatible with many notebooks and most smartphones and tablets. It works best with devices that can take advantage of charging protocols such as PD3, PPS, QC4+(QC3/QC3), FCP, AFC, Apple 5V2.4A, and BC1.2.
Protection from overvoltage, overcurrent, short circuit, and overtemperature is provided. This device requires a power input of 100-240V ~ 50/60Hz.

- Supported protocols: PD3, PPS, QC4+(QC3/QC3), FCP, AFC, Apple 5V2.4A, and BC1.2.
- Output ports: USB-C (two)
Gallium nitride is a crystal-like semiconductor material that boasts a broader bandgap than its silicon rival, allowing energy to pass through more efficiently. This results in higher power limits and lower operating temperatures.
Power Delivery Protocol
The Power Delivery (PD) specification denotes high power capabilities that allow USB-C PD-enabled devices to charge quickly over a USB connection. The two coupled devices negotiate a power contract, determining how much power will be pulled from the charger.
Quick Charge Protocol
Quick Charge (QC) is a battery charging protocol developed by Qualcomm. It manages power delivered over USB, communicating to the power supply and negotiating a voltage.
Fast Charge Protocol
This protocol, developed by Huawei, is designed for high-voltage fast charging.
This Ugreen charger supplies up to 45 watts from either of its USB-C ports. If both ports are connected to devices, the upper output is limited to 25 watts, and the second port can provide up to 20 watts.
The capabilities of the connected devices also help determine their charge rate. My phone is PD3 capable and can take full advantage of the 45 watts available from one of the charger’s ports. On the other hand, my electric toothbrush, which will only accept 5 volts at 1.5A, will draw only 7.5 watts from the charger.
This charger is an extremely useful gadget that I can store within the pocket of my overnight bag. Then, when I am traveling, it is a simple matter to connect the USB charging cables of my phone and tablet to this device and plug it into a handy AC outlet. The Ugreen Nexode Mini 45W charger is recommended.
