Gallium nitride (GaN) technology has steadily reduced the size of our everyday power bricks over the last few years, but Ugreen’s latest release pushes the form factor even further into the realm of pocketability. The company has just launched the Nexode Air 45W Ice Chip charger in China. Priced at 109 yuan ($16), its primary selling point is an ultra-thin profile that measures a mere 12.5mm thick.
Ugreen Nexode Air 45W Specifications
The exact dimensions are 62.2 x 42.74 x 12.5 mm, and it weighs about 54 grams. Ugreen says this design makes it roughly 58% smaller by volume than its previous 45W chargers. It has a flat, rectangular shape with foldable prongs, allowing it to slide into a pants pocket or the front pouch of a laptop sleeve without creating a noticeable bulge. The device comes in a silver-gray finish, with a single USB-C port located on the bottom edge.
That single port outputs up to 45W, which is enough to fast-charge modern phones, tablets, and smaller electronics like handheld gaming PCs. According to Ugreen, the charger can get an iPhone 17 Pro from zero to 67% battery in about half an hour. It supports standard fast-charging protocols and operates on a 100-240V input range, meaning it can be used internationally with a basic plug adapter.
Packing 45W into a chassis this small usually raises concerns about heat, which is where the Ice Chip name comes from. Ugreen says it is managing thermals using a high-density internal layout and a heat-conductive structure.
It also uses a system the company calls Thermal Guard, which actively monitors the charger’s temperature multiple times per second to keep the surface from getting too hot. The internal components are packed to achieve a power density of 1.496W/cm³, with an energy conversion efficiency of 90%.
For device safety, the charger includes standard protections against overcurrent, overvoltage, and short circuits, all housed in a flame-retardant shell. It also features a voltage regulation system that adjusts power delivery as your device charges.
Once a connected phone or tablet reaches 80% capacity, the adapter switches to a slower trickle-charge mode to help preserve the device’s battery health and keep temperatures down.
In related news, Belkin has recently introduced a new 45W GaN charger featuring a built-in retractable USB-C cable, while Anker has unveiled a 160W smart charger that supports Huawei’s 66W SuperCharge and Xiaomi’s 120W fast-charging standards.
