UGREEN Nexode Pro Power Bank Honkai: Star Rail Edition review: 55W in a compact, Yao Guang-themed package
Last updated:
The UGREEN Nexode Pro Power Bank Honkai: Star Rail Edition, a 10,000 mAh, 55W unit, now comes in a Yao Guang-inspired design.
- The AirPyra stacked design shrinks the footprint by 60% compared with a full-size flagship power bank. The body is made of V-0 flame-retardant plastic with a premium matte finish.
- It uses two EV-grade 21700 lithium-ion cells from Changhong Sanjie with a rated capacity of 36 Wh, which meets airline carry-on safety limits.
- It supports 55W Turbo Charge for Xiaomi devices and 45W Power Delivery/PPS fast charging for iPhones, Samsung phones, and thin-and-light laptops.
- A built-in braided nylon cable rated for 28 kg doubles as a carry loop, and a 1.18-inch TFT LCD color display on top shows real-time stats.

AirPyra stacked design and the Yao Guang look
One of the collaborations between UGREEN and publisher HoYoverse is the special-edition Nexode Pro Honkai: Star Rail Edition power bank. Unlike the familiar cool gray of the standard version, the UGREEN Nexode Pro Honkai: Star Rail Edition comes in peacock blue, with sharply printed artwork of the Divine Prognosticator General, Yao Guang. The shell is a blend of polycarbonate (PC) and V-0 flame-retardant ABS. The power bank also has reinforced metal details and a fine matte finish that resists scratches and fingerprints.
The technical highlight of the UGREEN Nexode Pro Honkai: Star Rail Edition is AirPyra, a column-style stacking of the circuit board and components. Thanks to a smart 3D layout, UGREEN fits 55W output and 10,000 mAh into a body measuring just 90.3 x 50.5 x 33.5 mm and weighing about 248.9 grams. Compared with the face of a phone like the iPhone 17 Pro Max, the power bank's contact area is up to 60% smaller, so it is easy to hold comfortably.
The UGREEN Nexode Pro Honkai: Star Rail Edition has a built-in 22 cm braided USB-C cable. It is woven from 48 durable nylon strands, passed a bend test of more than 10,000 cycles, and withstands a straight pull of up to 28 kg. When not in use, the cable tip clips into a groove on the edge to form a carry loop. You can then hook a finger through it and hold the phone with your palm without it feeling bulky. On the front, a 1.18-inch TFT LCD color display shows battery percentage, current direction, and instantaneous power in watts.
EV-grade cells and ThermalGuard cooling
Inside the compact body are two high-quality 21700 lithium-ion cells made by Changhong Sanjie to EV-grade standards. Wiring two 5,000 mAh cells in series gives a rated capacity of 36 Wh, with far better durability than flat pouch-style Li-Po cells. Good cells like these retain 70% to 80% of their original capacity after 800 to 1,000 charge cycles. The 36 Wh rating falls within the flight safety limits of international aviation bodies, so you can carry it directly into the cabin. Under standard operating conditions, the circuit's conversion efficiency is about 77%, delivering roughly 5,600 mAh of usable capacity at 5V/3A.
ThermalGuard combines hardware and algorithms to manage the heat generated when charging at up to 55 W in such a small body. An NTC thermistor measures temperature up to 720,000 times per hour (200 times per second) and automatically lowers current if the cells reach a dangerous 70 °C to 80 °C, then restores full output once temperatures fall to 50 °C to 60 °C. The passive cooling hardware also includes a 1,176 mm² metal plate, a silicone thermal pad, and 3,115 mm² of insulation cotton wrapped around the cells. This design keeps heat from pushing directly to the outer shell, and works alongside a multilayer protection chip for circuit safety.
Charging performance and limitations
When charging a single device through either the standalone USB-C port or the built-in cable, the UGREEN Nexode Pro Honkai: Star Rail Edition delivers its full output with ease. It supports multiple protocols, including Power Delivery (PD) 3.0, PPS, Quick Charge (QC) 3.0, and Turbo Charge. With Xiaomi or Redmi phones, it activates 55W (11V/5A), charging from 0% to between 55% and 90% in about 30 minutes. Samsung smartphones such as the Galaxy S24 Ultra or S25 Ultra readily negotiate Super Fast Charging 2.0 at 45W. An iPhone 17 Pro Max charges from 30% to 70% in half an hour. The UGREEN Nexode Pro Honkai: Star Rail Edition also has a 22.5W USB-A port for fast charging older mobile devices.
However, the hardware limits of the compact AirPyra design show when you connect multiple devices at once. Because all ports share the same buck-boost converter, plugging in two or three devices forces the system to disable all fast-charging identification chips. Total output is then locked at a maximum of 15W (5V/3A), split to only about 5 W to 7.5 W per port. That speed is only suitable for topping up or overnight charging, not fast charging. The TFT display also shows only the combined output rather than each port separately.
On the upside, recharging the UGREEN Nexode Pro Honkai: Star Rail Edition itself is impressive, with input of 35W to 45W over the USB-C port. It takes about 1.5 to 2 hours to fill the battery from empty if you use a charger with matching output. The controller also supports pass-through charging, so you can charge the power bank while powering a phone from it. In addition, a low-current mode, activated by holding the power button for 3 seconds, safely charges low-power devices such as wireless earbuds and smartwatches.
Real-world use
The sturdy build and the convenience of the built-in cable on the UGREEN Nexode Pro Honkai: Star Rail Edition are beyond question. However, with a cylindrical body 33.5 mm thick and weighing about 249 grams, it suits a backpack better than a pants pocket. The built-in TFT color display has a modest resolution and is not especially sharp. Also, the 45W PD output sometimes won't work with a few laptop models that need a higher input power.
The UGREEN Nexode Pro Honkai: Star Rail Edition has an international list price equal to the standard Space Gray version at 59.99 USD. In Vietnam, the gray version typically sells at promotional prices ranging from 600,000 to 1,156,000 đồng. Since the hardware and performance of the two versions are identical, the standard gray model is the better deal for anyone who cares about value for money. The higher price of the Yao Guang edition is still reasonable if you are a Honkai: Star Rail fan, since it offers collectible and display value along with the same performance.
The UGREEN Nexode Pro Honkai: Star Rail Edition packs EV-grade cells and a digital display into an impressively compact body. That said, charging several devices at once throttles output to 15W. This power bank is therefore built mainly for fast charging a single device at a time. And at more than 3.3 cm thick in a cylindrical form, you will want a bag or backpack to carry it comfortably.
