Xiaomi Mi Power Bank 3 Pro (20,000mAh): Review/Test

#xiaomi #miowerbank3pro
The latest updated 20,000mAh power bank from Xiaomi, the Pro model is an update over the 2C which I tested 18 months ago. This new model offers a dual power USB Type-C connector for charging or output, support for ultrabook and MacBook Pro charging, quick charge and dual or triple USB output.

I test the charge capacity, the discharge capacity, output with 2 or 3 ports, weight and provide an overview of features, as well as a quick comparison to the 2C

Sample supplied via Banggood for independent testing
Details from the maker:
Features:
-20000mAh High capacity
-Supports USB-C both for input and output, up to 45W.
-The USB Type-A single port provides 5V/2.4A, 9V/2A, 12V/1.5A fast charge but it gives 5V/3A output when two charging ports are working at the same time.
-Surge protection, short circuit prevention and more advanced safety features protect you and your devices.

Now this is what you call a detailed review. I wish more reviews are like this.

[drakzin]

Fantastic review, quick to the point and lots of technical details. Exactly what I was after. Thank you!

[pcglvz]

Thanks for this! Does it automatically charge once a device is connected or do you have to turn it on manually?

Xiaomi powerbanks is built like a tank, the quality and performance of xiaomi PB's is on par with the leading PB manufacturer's like anker..
I got a Mi PB 2c and it lasted 3 year's and still functioning properly till now, take note that my 2C takes a lot of beating from drops too..

[computerjantje]

Thank you for the video. What I do not understand is the 9, 12 and 20 volt output possibitly? A USB port does, as far as I know, always 5 volt. How does the powerbank know when to up the voltage on the pins to something different(higher voltage) out? Thank you for your reply.

I’d like to buy either this xiaomi pb 3 pro 20000 or the older version of the mi 2C. I am looking for the fast charging feature. For that different prices of the two products which one do you recommend?

[Bogak]

nice review, i have a question.
Can you charge the powerbank via USB-C while using the powerbank to charge devices via the USB-A ports ?

[이지컴퓨터]

Thanks great review!!!
Only 5V output is abalable in passthrough charging?
And,
charging and discharging with usb C port in the middle is possible?
Thanks!

[koerus]

Do you still recommend buying it in September 2021?

[madbull]

nice vid. by the way what cable did you use to charge the powerbank? for only 5 hours

[rendisupiana]

it's power delivery for nintendo switch?

[uabir]

Nice video. Edgar about the 20v efficiency when charging laptops? Do you get around 13000mAh as well or is it something different?

[danielbanares]

Great video, can this pb support vooc charge of f11pro?

[hisenburglar]

Thank you for the review. Does it support through put? i.e., charge phone through usbA while being charged through usbC

So does that mean both the older Mi 2C 20000 MaH powerbank and this newer can discharge about 13000 MaH but the newer one can discharge faster and is heavier?
I'm think of buying either of them but ai just can't decide. Older 2C Mi or newer Redmi power bank should I choose? I'm planning to buy it alongside with a Redmi Note 7 or Note 7 Pro

[daryltan]

hi! do u know if i can use a 61w MacBook USB C charger to charge this power bank? or will it damage the battery/ cause an explosion?

[bro_vn]

Hi. If connect two usb-a out, whether current will 12V 3A?

[aemieromero]

Nice review! Hi i would like to ask for your advice. I'm planning to buy a power bank. Which is better between Mi power bank 2c 20k Mah or this 3 pro? Thank you

[micsunday]

No proper mention of PD . Which makes this a ridiculously good battery for things like Nintendo switch. Also very fast to recharge with 45w PD outlet. So much better than waiting for 12hrs + micro usb
