Analysis of Mi 20000mAh Mi Power Bank 2

The Mi 20000mAh Mi Power Bank 2 is the portable battery originated by the evolution of the first generation of 20,000 mAh. In design, we are facing a more compact and manageable device, but let's see its interior.

It has a real capacity of 14,000 mAh and includes as a novelty the use of LiPo cells compared to the previous version. It has 2 output ports, which have a wide working range since they can work with the following voltages and amperages: 5.1V/2.4A or with fast charge: 5.1V/3.6A; 9V/2A; 12V/1.5A.

This Power Bank supports Quick Charge 3.0 technology in both ports simultaneously, thus allowing you to charge your mobile as if it were with its original charger. We can also charge devices that do not need much power such as watches, bracelets, or Bluetooth transmitters, as long as we activate Low Power Charging.

It may be a somewhat large product to carry in your pocket, but it is perfect to carry in your backpack and carry any device in an appropriate way.

It supports fast charging of the iPhone.

The two-way charging speed is very fast and the capacity is also sufficient.

It is a power supply with a large capacity. The daily load is very powerful, although yes, it is too great. It may be a bit heavy, but the quality is good. Color and texture are some of the most positive aspects.

Classic black! Great load capacity. You can go out and feel safe.

High quality product, somewhat heavy, but very powerful and with a very pleasant touch.

It does not deliver the load it promises. I have fully charged it three times to make sure it works. I have a 2500 mAH mobile and it only charges it 3-4 times before it is completely drained. I think it doesn't work well.

Excellent Powerbank, it charges my iPhone xR about 6 full times, very light for its capacity and the materials are first class, a very good price for the quality of the product Highly recommended!

I was tired of looking for a Power Bank that would last what the manufacturer actually says. As a summary, all the ones I have tried and all the ones I have read do not usually offer accurate information about the load capacity. In my case, this 20,000 mAH Power Bank has a real capacity, measured with professional equipment of 17,000 mAH and therefore it can be said that it is the least bad and therefore the best of all.

I have charged three mobiles and according to the charge indicator it still has more than half. It doesn't take long to be full. It charges the mobile pretty fast. It is very useful for those times when you need your mobile and you don't have a plug available, or when you don't have time to leave it plugged in.

Very good quality. It gives for several charges of the mobile phone. It is the best external battery I have ever owned. The worst is the size.
