MI Powerbank Boost Pro 30,000mAh review

Hello and welcome to my review of the MI Powerbank Boost Pro. This oddly named MI powerbank is a product of Chinese Tech Giants Xiaomi and it is a midrange powerbank.

This Powerbank burst onto the scene around January of 2023 and it has generated a lot of hype. Due to this, I bought one myself and I have put it to the test. Join me and find out if this Mi Powerbank is all it is made out to be.

MI Powerbank Boost Pro


This powerbank uses standard Lithium polymer batteries with an advertised capacity of 111Wh or 30,000mAh (at 3.7V). Please note that this advertised capacity is just eye candy and it is not the true capacity. The true capacity is calculated at 5V, not 3.7V. To get the real capacity:

  • 3.7V × advertised capacity ÷ 5V
  • 3.7V × 30,000mAh ÷ 5V
  • 111,000mAh ÷ 5V = 22,000mAh (5V)

The actual capacity is around 22,000mAh (5V). This means that if you have got a phone with a 5,000mAh battery, this powerbank should charge it around 4 – 5 times (roughly). You should also note that this powerbank takes around 10 hours to fully charge, so keep that in mind.

There are a total of 4 ports on this powerbank, two of these are USB A ports, one is a USB-C port and the last one is a micro-USB port. The micro-USB port is used to charge the powerbank and it tops out at 18W. The USB-C serves dual functions as it can both charge and discharge the powerbank. It charges the powerbank at 24W but gives out power at 18W. Finally, the USB A ports are used to charge other devices and give out power at 18W max as well.

Charging features

This powerbank lacks modern features such as wireless charging, but it has got intelligent charging. This means that the powerbank can automatically adjust the current depending on the load. So if you plug in a phone that only supports 10W or 15W charging, the powerbank will adjust the power delivery to match them.

However, there are some power sensitive devices that need low powered modes to charge. These include devices like TWS earbuds, smartbands etc. This powerbank can cater to them as well. To enter this low-powered mode, double click the button on the side.

Build Quality, Looks and Design of the MI Powerbank Boost Pro

This powerbank is very sturdy and well built. It has a rectangular form factor and uses a plastic case. It is deep black in colour. There’s single button on the side that wakes up the powerbank. It is also rather hefty and will not fit into your pockets but has enough grip and width to fit into one’s hands.


After two weeks with this powerbank, I can say that this powerbank is worth the hype. It is a very solid device that does what it is supposed to do. I cannot heap enough praise on this powerbank.


This powerbank sells for ₦‎25,000 (Nigerian Naira) which is around $32 (US), ₹2,700 (Indian) or Ksh4,700 (Kenyan)


If you can spare the funds, this powerbank is good for the job.
