UGREEN Nexode Air 65W Honkai: Star Rail Edition charger review
Last updated:
The UGREEN Nexode Air 65W Honkai: Star Rail Edition uses GaN semiconductors to stay compact, and it comes dressed in a Yao Guang-inspired design.
- Ultralight at just 73 g and 31 x 33 x 40.5 mm, with folding prongs that sit flush against the body and a multi-layer UV-printed Yao Guang design.
- Next-generation GaN semiconductors and the Airpyra structure push power conversion efficiency as high as 90.11% under heavy load tests.
- A single USB Type-C port eliminates the power cuts that come with renegotiating current, and it charges MacBooks, iPhones, and Android phones well.
- The Thermal Guard thermal control system keeps surface temperature at 50.9 °C, and the charger carries Germany's strict TÜV SÜD S-Grade safety certification.

A pint-sized charger in Yao Guang colors
UGREEN has teamed up with publisher HoYoverse to bring the world of Honkai: Star Rail to accessories, including the Nexode Air 65W charger. Inspired by Yao Guang, the Diviner General who commands the Xianzhou Yuque warship, this charger swaps the usual gray-black for a peacock blue finish. The character art and multicolored cloud patterns are applied with multi-layer UV printing, which creates a raised 3D effect with strong adhesion. It resists peeling and picks up less hand sweat after long-term use.
The UGREEN Nexode Air 65W Honkai: Star Rail Edition has model-worthy measurements: 31 x 33 x 40.5 mm and a weight of just 73 g, roughly the size of a ping-pong ball. The rounded cube shape slips easily into a jeans pocket or a backpack's accessory compartment without taking up space. The body is finished with 24 laser-etched grooves that add grip and make plugging and unplugging easier. The ring around the port is made of translucent frosted glass, a classy touch that stands out.
The flat US-style prongs fold smoothly against the body thanks to a carefully tuned hinge. This folding design reduces the risk of the metal prongs scratching other electronics when they share a bag. For collectors, this charger is also part of a limited Collector Box Set that opens like an East Asian folding fan. Besides the 65W charger, the box includes exclusive items such as an acrylic chibi figure, a hologram-stamped commemorative ticket card, and a matching strap.
Gallium nitride and Airpyra Tech
The main reason UGREEN can deliver 65 W in a body 74% smaller than a traditional silicon charger is the wide-bandgap semiconductor gallium nitride (GaN). With a critical electric field of 3.3 MV/cm and the presence of a two-dimensional electron gas (2DEG), GaN transistors can switch at frequencies in the megahertz (MHz) range with almost no energy loss. That lets bulky passive components such as transformers and inductors shrink dramatically.
To make the most of the available space, the UGREEN Nexode Air 65W Honkai: Star Rail Edition uses Airpyra, a 3D stacking technology. It arranges interleaved component clusters around a HYASiC HYC3688H controller chip with integrated 700 V GaN. Notably, UGREEN fits only one USB Type-C output port to keep power delivery continuous. This approach completely removes the power renegotiation cuts commonly seen on multi-port chargers.
Charging performance, power cleanliness, and temperature
The Nexode Air 65W's value shows in the purity of its output power. Measurements with specialized equipment show VBUS ripple of only 229 mV (about 1.1% of the output voltage), with high-frequency spikes held below 90 mV. With clean, smooth power, the power management IC (PMIC) in a smartphone or laptop stays safe, and battery cells wear less when charging overnight.
In a continuous charging test at the rated 65 W for 60 minutes, the UGREEN Nexode Air 65W Honkai: Star Rail Edition held an impressive conversion efficiency of 89.58% to 90.11% with no voltage drop. Real-world charging speeds hit 0% to 51% in 30 minutes for a MacBook Air M4, and 20% to 85% in 35 minutes for an iPhone 17 Pro Max. With Super Fast Charging enabled, it can charge a Samsung Galaxy S25 Ultra over PPS in 40 minutes. Even Windows laptops such as the Lenovo Yoga Pro 7i Gen1 went from 0% to 55% in 38 minutes.
Although high charging power is packed into a tiny body, overheating is handled well thanks to Thermal Guard. An NTC sensor continuously monitors PCB temperature and automatically lowers the charging current if components exceed 70 °C to 80 °C. Once temperatures drop, the charger restores full power. Measurements with an infrared thermometer show the casing warms to only about 50.9 °C at its hottest point. The UGREEN Nexode Air 65W Honkai: Star Rail Edition also meets Germany's TÜV SÜD S-Grade safety standard for heat.
Price and use cases
Unlike many collaboration products, which tend to carry a markup because of licensing costs, UGREEN prices the Nexode Air 65W Yao Guang edition at 699,000 VND. That is even lower than the 860,900 VND list price of the standard gray version, though the regular model is sometimes discounted to 500,000 VND during promotions. Compared with Apple's 70W charger, which costs over 1,500,000 VND, the UGREEN Nexode Air 65W Honkai: Star Rail Edition is up to 66% smaller and half the weight, and its GaN semiconductors run much cooler.
Overall, the UGREEN Nexode Air 65W Honkai: Star Rail Edition is a well-considered choice for anyone who needs reliable power. At 73 g, and with a 100-240 V input range, it makes an ideal travel accessory. It delivers enough power for a working ultrabook and is compact enough to slip into a pocket. Whether you buy it for Yao Guang or simply need a durable GaN charger, it delivers on both collectible and practical value.
The UGREEN Nexode Air 65W Honkai: Star Rail edition stands out for its GaN semiconductors and ultracompact Airpyra technology. However, with only one USB Type-C port, you cannot charge two devices at once and have to swap between them. In addition, the 100 W braided cable included in the box (also in an attractive blue, with a cable wrap in Yao Guang style) uses the USB 2.0 data standard (480 Mbps), so it is only suitable for charging.
