As a portable charger to carry out, I tested the black UGREEN Nexode Wavy 10000mAh 45W (Model PB603), provided by UGREEN, by charging an iPhone. This product is a model that combines a screen displaying remaining battery, output, and remaining time, along with a built-in USB-C cable that can be stored in the main unit. In addition to the built-in cable, it also has a USB-C port and a USB-A port, allowing connection to devices via three channels in total.
In this article, we will provide an overview from unboxing to charging, storage, and portability, accompanied by actual product photos.

Nice to meet you!
Overall Review of UGREEN Nexode Wavy 10000mAh 45W
In conclusion, we rated this model 5 out of 5 stars. The reasons are three points confirmed through actual use: First, you can check the remaining battery, output, and remaining time on the device’s screen during charging. Second, the unused USB-C cable can be stored within the main unit for portability. Third, it connects to devices via three channels: the built-in cable, a USB-C port, and a USB-A port.
This configuration addresses common complaints about portable chargers, such as “I forgot the cable and can’t use it” or “I don’t know the remaining battery or charging speed,” all within a single unit. For those who charge USB-C devices one by one on the go, this unit, with its integrated screen and cable, is easy to handle.
When using the USB-C port alone, it supports a maximum output of 45W, while simultaneously charging multiple devices results in a total maximum of 15W. We rated it as an ideal unit for those who want to charge devices quickly, one at a time.

MISTERSAFESpecifications of UGREEN Nexode Wavy 10000mAh 45W
The model used was the black PB603, with product number 95294 as indicated on the box’s sticker and the device itself. The specifications below are based on UGREEN’s official product page and the rating label on the box.
| Item | Specification |
|---|---|
| Advertised Capacity | 10000mAh (Numbers on label to be confirmed in next section) |
| Cell/Rated Capacity on Device/Box | Cell 5000mAh (Two Cells in Series) / Rated 6000mAh TYP (5V・3A) / 39.1Wh |
| Built-in Cable | Approx. 22cm strap-type USB-C cable (for both input and output) |
| USB-C Cable/USB-C Port Single Output | Max 45W (20V=2.25A series) |
| USB-A Single Output | Max 22.5W |
| Multiple Port Simultaneous Use | Total Max 15W (5V=3A) |
| Input to Device | Max 36W (via either built-in cable or USB-C port) |
| Connection | Built-in USB-C cable, USB-C port, USB-A port. Up to 3 devices simultaneously |
| Supported Protocols (USB-C System) | PD3.0 / PPS / QC3.0 / QC2.0 / SCP / FCP / AFC / Apple 5V=2.4A / BC1.2 |
| Size/Weight | Approx. 109×69×18mm / Approx. 211g |
The key point is that “maximum 45W when using USB-C alone” and “total maximum 15W when using multiple ports simultaneously” are different conditions. The rating table on the box also has separate rows for “USB-C Cable,” “USB-C Port,” “USB-A,” and “Multi-port,” making it easier to understand which scenario applies to your usage.
How to Read Capacity Indications
The capacity indicated on the sales page is 10000mAh. However, looking at the labels on the device and the box, different numbers are listed: “Cell Capacity: 5000mAh (Two Cells in Series),” “Rated Capacity: 6000mAh TYP 5V3A,” and “Rated Energy: 39.1Wh.” Since these are all shown in the same photo as the sales sticker “10000mAh 45W,” you can compare the differences in notation at a glance.
Reading the label, it indicates a configuration of two 5000mAh cells in series, and the advertised 10000mAh corresponds to the combined capacity of the cells. 6000mAh is the rated capacity when drawing 5V・3A, and 39.1Wh is the battery’s energy amount. The number of times a smartphone can be charged varies depending on usage, so it’s reassuring to refer to the number closest to your own usage.
Ms. GadgetThe capacity is 10000mAh, right? Why does the label say 5000mAh?
Mr. GadgetIt’s configured with two 5000mAh cells in series, and the label lists cell capacity, rated capacity 6000mAh, and 39.1Wh. You can see the difference at a glance by comparing the labels in the photo.
Review and User Experience of UGREEN Nexode Wavy 10000mAh 45W
Package and Included Items
The front of the received box features a row of product highlights: “45W USB-C Bidirectional Fast Charging,” “Smart TFT Display Real-time Status,” “Built-in Braided Cable/Handle,” “Premium ATL Cells,” and “Airline-Approved,” along with a diagram showing the three-channel configuration of “1×USB-C Cable In/Out・1×USB-C In/Out・1×USB-A Out.” We will examine how each of these advertised features actually performs.
Upon opening, the contents are the main unit and a set of documents. It included a User Instruction, a manual for model PB603, a Help Guide, and recycling information. Since the cable is designed to be attached to the main unit, you can start powering USB-C devices as soon as you open the box.
Charging an iPhone with the Built-in Cable
I used it in a situation where my iPhone’s battery was running low while out. I took the unit out of my bag, detached the tip of the cable secured to the back, and plugged it directly into the iPhone’s USB-C port. Since there’s no need to search for a separate cable, the time from taking it out to starting the power supply is short.
The photo shows the full path: “unit → built-in cable → checker → iPhone.” Since the cable extends directly from the unit, it doesn’t get tangled on the desk, and you can view the screen while holding the unit with the cable connected. The built-in cable’s connector is USB-C only, so for devices with non-USB-C connectors, you would use the ports described later and your own cables.
Values Displayed on the Checker
Mid-charge, I inserted a RouteR USB-C checker to observe the actual electrical flow. At the time of the photo, the display showed 8.817V・2.570A・22.659W. The checker also showed the temperature of 33°C, cumulative current/power values, and elapsed time.
In a shot taken at a different time, it displayed 8.817V・2.791A・24.608W, showing in two photos how the output varies even when charging the same iPhone.
The USB-C output of this model is a maximum of 45W when used alone. In the scenario where I charged an iPhone, it delivered approximately 22.7W to 24.6W.
Ms. GadgetDoes that mean it can charge at 45W?
Mr. GadgetWhen using USB-C alone, it supports up to 45W. Even when connected to an iPhone, it was able to supply around 22W. With 45W, it’s convenient for high-power devices like laptops.
Viewing Remaining Battery, Output, and Remaining Time on Screen
Looking at the device’s screen several times during charging, three items were displayed simultaneously: remaining battery (%), output (W), and remaining time (h/m). Arranging the photos taken in chronological order, the numbers progress from 26%・0h15m during power supply, to 24%・23W・0h19m, and then 18%・23W・0h14m. You can easily track the decrease in the unit’s remaining battery and an estimate of how much longer it can supply power to a device, all from the palm of your hand.
What’s noteworthy is that the “23W” output displayed on the screen almost perfectly matched the 22.659W measured by the checker at the same time. Knowing that the display shows values close to actual measurements makes it easier to use; for example, you can read on the screen how much longer the power supply will last while charging at a cafe. The text “Power Bank 39.1Wh 45W” is also constantly visible at the bottom of the display.
Features such as temperature, voltage, charge cycle count, and health status display, as well as the ability to tap the power button five times to view an anomaly history, are also provided.
Storing and Carrying the Cable
The form when not in use is also a key feature of this product. The approximately 22cm green braided cable forms a loop from its base, which can be used as a handle or strap. It’s truly convenient to hook a finger into the loop when taking it out of a bag, and lifting it from its resting place felt natural.
For storage, the connector tip is secured along the back side. When secured, the cable lies flat against the surface, resulting in a neat appearance. However, the loop portion remains on the side of the main unit, so when placing it in a slim pouch or case, it’s advisable to account for this extra width.
Distinguishing Between USB-C and USB-A Ports
Looking at the top surface, three channels are arranged in a row. The recess where the built-in cable’s connector is stored has the engraving “IN 1/OUT 1,” the USB-C port has “IN 2/OUT 2,” and the USB-A port has “OUT 3.” Since the built-in cable is bidirectional (for both input and output), charging the unit can be done either by connecting a charger directly to the cable itself or via the USB-C port (maximum input to the unit is 36W).
The inner tongue of the USB-A port is purple, and you can also use your existing USB-A cables. It can connect to older earphones and USB-A output peripherals, making it a helpful option for those who still have a mix of devices that haven’t fully transitioned to USB-C. Low-current mode is supported only by the USB-A port.
The connection supports up to 3 devices, and the fact that simultaneous use of multiple ports results in a total maximum of 15W (5V=3A) is a decisive factor when choosing. For charging a smartphone and earphones together overnight, it’s sufficiently practical. If you want to charge multiple devices quickly at the same time, a model with a higher total output is more suitable.
Size and Form Factor for Portability
The size is approximately 109×69×18mm, and it weighs about 211g. There’s a small oval button on the side, and when placed next to a small eraser, you can get a sense of its 18mm slimness and length. The side with the screen features silver-gray wavy ribs, and the texture when held is matte.
While its slimness makes it easy to slip into a jacket’s inner pocket or a bag’s compartment, my experience carrying it was that the required width is slightly greater than the stated dimensions due to the cable’s loop protruding from the side. The device label also includes the PSE mark and “Airline Friendly” notation, but please check with your airline regarding carry-on regulations.
Approach to Safety
The box and official product page highlight that this model uses ATL cells, has undergone five safety tests (nail penetration, pressure resistance, heating, overcharging, and lithium deposition), features 100 temperature checks per second, and includes 14 types of protection functions. Verification results showing over 80% capacity retention after approximately 800 charge cycles, along with features like pass-through charging and automatic recording of anomaly history, are also introduced, conveying a sense of security for a battery carried daily.
Additionally, UGREEN recently announced that actor Kento Yamazaki has been appointed as their brand ambassador.
Summary
A Model Combining Screen and Cable in One Unit
The UGREEN Nexode Wavy 10000mAh 45W is a portable charger that integrates a screen displaying charging status and a retractable USB-C cable into a single unit. When actually charging an iPhone, I was able to connect it without searching for a cable and monitor the remaining battery and time on the screen. For those who primarily charge USB-C devices one at a time, the screen, built-in cable, and three-channel configuration directly translate into benefits with this unit.
The built-in cable’s connector is USB-C only, and simultaneously charging multiple devices results in a total maximum of 15W. If these two points align with your usage, this product allows you to fully utilize the convenience of the screen and cable.
Ms. GadgetCan I charge multiple devices simultaneously?
Mr. GadgetYou can connect up to 3 devices, but simultaneous use results in a total maximum of 15W. This model is suited for charging devices quickly one by one, so if you need high output for multiple devices simultaneously, please check out models with higher total output.
