Having considered its built-in connector that eliminates the need for cables, its output and battery capacity sufficient for charging a smartphone, and its overall size, I feel that the “UGREEN Built-In USB-C Connector Power Bank 5000mAh” is a smartphone-focused portable charger that is specialized above all in portability.

It also has plenty of appealing points, such as an adorable design and the convenience of doubling as a smartphone stand.

While the only slight concern is whether the connector part might snap, it is unlikely to break under normal use.

Since you can charge without having to carry cables around, it is recommended for those who want to minimize their luggage as much as possible when going out and those looking for a portable charger for their smartphone.

(Built-in USB-C Connector / USB-C Port)
 Single port use: 10V⎓2.25A / 5V⎓3A / 9V⎓2.22A / 12V⎓1.5A
Multiple ports use: 5V⎓3A Max
Specifications of the “UGREEN Built-In USB-C Connector Power Bank 5000mAh”

It is capable of approximately 20W output when using a single port, and up to 15W when using multiple ports.

Mr. Gadget

A 22.5W output is only available for Huawei devices.
For all other devices, the maximum is 20W.

With this level of output, charging a smartphone is more than sufficient.
I think you can also charge tablets if you don’t mind slow charging.

Mr. Gadget

While there are smartphones that can be charged at even higher outputs, this will suffice as long as you don’t demand high speeds.

Ms. Gadget

In short, this is plenty for normal charging without worrying about speeds!

5000mAh capacity capable of charging an iPhone about once

Regarding the capacity of the 'UGREEN Built-In USB-C Connector Power Bank 5000mAh'

This portable charger has a capacity roughly enough to charge a smartphone about once, give or take.

Ms. Gadget

It might feel a little lacking…

Mr. Gadget

Though if you treat it strictly as a portable option for on-the-go use, this much is fine.

Mr. Gadget

It’s definitely great that it comes with a protective cover in the first place!

Having two ports is a nice little bonus

Regarding the ports of the 'UGREEN Built-In USB-C Connector Power Bank 5000mAh'
There are input/output ports other than the connector section
Output of the 'UGREEN Built-In USB-C Connector Power Bank 5000mAh'
Confirmed an output of approximately 20W

Because there are input/output ports in addition to the connector section, power can be output from 2 ports.

However, when using multiple ports, the combined output is limited to a maximum of 15W.

Mr. Gadget

Being able to output from 2 ports is a nice feature!
Expanding what you can do, such as charging a smartphone and earphones simultaneously, is important.

Ms. Gadget

Well, using 2 ports does require one cable, though.

LED Battery Level Display

Ms. Gadget

Being able to use the stand function to watch videos while charging is quite convenient!

Mr. Gadget

Though it can be a bit scary thinking about whether the connector might snap if excessive force is applied.
Well, I’m sure that aspect has also been considered and designed against.

Conclusion

If you want to minimize your luggage above all else, this is the perfect fit!

After using the “UGREEN Built-In USB-C Connector Power Bank 5000mAh” this time, considering its built-in connector that requires no cables, its output and battery capacity sufficient for charging a smartphone, and its size, I felt it is a smartphone-focused portable charger specialized entirely in portability.
