The Anker Power Bank (25000mAh, Built-In & Retractable USB-C Cable) is available in two colors: black and silver. This time I received the black version.
In addition to the mobile battery itself, the box contained a warranty card, safety instructions, and a storage bag.
The Anker Power Bank (25000mAh, Built-In & Retractable USB-C Cable) looks like this.
The strap is not just a string, but a USB Type-C cable that can input and output power.
When unfolded from the strap state, it looks like this. The maximum output is 100W, and the voltage and current combinations are '5-11V=3A / 5V=3A / 9V=3A / 10V=2.25A / 12V=3A / 15V=3A / 20V=5A'.
The strap-type USB Type-C cable is approximately 30 cm long.
This is a retractable USB Type-C cable.
It can be pulled out like a vacuum cleaner cable. It is very convenient to be able to charge two devices without having to prepare a separate cable. The output is up to 100W, and the voltage and current combinations are '5-11V=3A / 5V=3A / 9V=3A / 10V=2.25A / 12V=3A / 15V=3A / 20V=5A'.
The retractable USB Type-C cable is approximately 67 cm long.
I recorded a video of the USB Type-C cable being pulled out and wound up. The length of the cable that can be pulled out is infinitely adjustable.
The front is equipped with a display that can display various information.
On the left side are the power button, USB Type-C port, and USB Type-A port.
The maximum output of the USB Type-C port is 100W, and the voltage and current combinations are '5-11V=3A / 5V=3A / 9V=3A / 10V=2.25A / 12V=3A / 15V=3A / 20V=5A'. The maximum output of the USB-Type-A port is 33W, and the voltage and current combinations are '5-11V=3A / 5V=3A / 9V=2A / 10V=2.25A / 12V=1.5A'.
You can change the display content each time you press the power button.
This shows the remaining battery power and output.
It is also possible to check the output from each port individually.
You can also check the battery temperature.
Additionally, you can check the battery cycle count and health status.
Pressing the power button twice in a row switches the USB Type-A port to low current mode, making it suitable for charging smart watches, wireless earphones, etc. While in low current mode, a blue dot appears in the upper right corner of the battery level indicator on the display.
You can also turn off the display by pressing and holding the power button for 2 seconds.
The input/output information for each port is written on the bottom.
The actual weight is 590g.
The total output of the four ports is a maximum of 165W, so you can charge three smartphones while still having plenty of power.
The Anker Power Bank (25000mAh, Built-In & Retractable USB-C Cable) itself can be charged using a retractable USB Type-C cable.
It can also be charged using a strap-type USB Type-C cable.
In addition, you can charge it from the USB Type-C port on the side. The maximum input when charging is 100W for all three ports, and it supports input of '5-11V=3A / 5V=3A / 9V=3A / 10V=2.25A / 12V=3A / 15V=3A / 20V=5A'.
When multiple ports are connected to a power source, charging will occur from the port with the highest input.
While charging, the remaining battery level is displayed to the nearest 0.01%, as well as the input power and estimated time until full charge.
It also supports pass-through power supply, which allows you to charge the 'Anker Power Bank (25000mAh, Built-In & Retractable USB-C Cable)' while also powering other devices from the 'Anker Power Bank (25000mAh, Built-In & Retractable USB-C Cable)'.
When pass-through power supply is in progress, the display will show 'Pass Through.'
The Anker Power Bank (25000mAh, Built-In & Retractable USB-C Cable) also displays various information that indicates a problem with the battery. For example, the following screen shows that the device has entered 'active cooling mode,' which transitions to a low-power state when the battery is too hot.
When the battery level falls below 10%, a red warning screen will be displayed.
If an abnormality occurs in the current or voltage and circuit protection is activated, the following screen will be displayed.
If the battery temperature is too high or low, it will enter 'temperature protection mode' and stop working until the temperature returns to normal range.
