『UGREEN Built-In USB-Cコネクター Portable Chargers 5000mAh』のReviews
JP EN FR ES 中 한 DE 繁 VI ID ไท PT

The “UGREEN Built-In USB-C Connector Power Bank 5000mAh” is, in my opinion, a power bank specifically designed for smartphones that prioritizes portability above all else, given its cable-free built-in connector, sufficient output and battery capacity for charging phones, and overall size.

There are many other delightful features as well, such as its charming design and the convenience of being able to double as a smartphone stand.

While I do have slight concerns about whether the connector might break, it is unlikely to happen under normal usage conditions.

Since you can charge without having to carry cables, I highly recommend this for those who want to minimize their carry when heading out and those looking for a dedicated smartphone power bank.

Actual Usage Impressions

Recommended for charging smartphones and more

Built-in style that doesn’t require cables

Because it has a built-in connector, you don’t need cables

You can reveal the Type-C terminal by removing the cover like this

The biggest feature of this power bank is that it comes with a built-in connector, so you can charge without needing any cables.

Ms.Gadgets

In short, as long as you have this one device, you can easily charge anywhere!

Max 22.5W output is sufficient for charging smartphones

I measured the output to a smartphone

I was able to confirm an output of about 20W

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

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

Mr.Gadgets

22.5W output is only possible for Huawei devices.
Everything else is limited to a maximum of 20W.

With this level of output, you can sufficiently charge a smartphone.
I think you can also charge a tablet, provided you don’t mind a slower speed.

Mr.Gadgets

There are smartphones that can charge at higher outputs than this, but if you aren’t chasing speed, this should be fine.

Ms.Gadgets

In other words, if you aren’t worried about speed and just want to charge normally, this is enough!

5000mAh capacity capable of charging an iPhone about once

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

This power bank has a capacity that basically allows for one full charge of a smartphone, give or take.

Ms.Gadgets

That might be a little underwhelming…

Mr.Gadgets

I think it’s fine as long as you think of it as a portable device.

Playful and adorable design

Protective cover for the connector

As you can see from the photo above, the protective cover for the connector features a charming design.

Mr.Gadgets

First of all, I’m glad it comes with a protective cover!

Ms.Gadgets

Indeed! It’s great to have such cute, playful touches!

Having two ports is a nice bonus

I confirmed an output of about 20W

Because there is an input/output port besides the connector, you can output from two ports.

However, when using multiple ports, the total output is limited to 15W.

Mr.Gadgets

Being able to output from 2 ports is a nice feature! Being able to charge a smartphone and earphones at the same time expands the range of possibilities.

Ms.Gadgets

Well, you do need a cable to use the second port.

The “UGREEN Built-In USB-C Connector Power Bank 5000mAh” can also be used as a smartphone stand.

Ms.Gadgets

Being able to watch videos using the stand function while charging is really convenient!

Mr.Gadgets

Though it is a bit scary to think the connector might break if you apply strong force. Well, I’m sure that has been considered and addressed in the design.

Summary

If you want to minimize your carry, this is perfect!

Having used the “UGREEN Built-In USB-C Connector Power Bank 5000mAh,” I think it is a power bank specifically designed for smartphones that prioritizes portability above all else, given its cable-free built-in connector, sufficient output and battery capacity for charging phones, and size.

While I do have slight concerns about whether the connector might break, it is unlikely to happen under normal usage conditions.

Mr.Gadgets

Well, it would be scary if you put it in your pocket while charging and sat down, causing abnormal force to be applied.

Since you can charge without having to carry cables, it is recommended for those who want to minimize their carry when heading out and those looking for a dedicated smartphone power bank.
