I bought Mi power Bank 2i 20000 mAh in June 2022 & since then I am using it daily whether in my home or while in travel. Based on my experinece of using it I can say that it’s very helpful, useful, really provide good battery backup plan.
It really helps me while I am in travel. You are doing something important like payments, transactions, sending mails etc. while in travel your phone can switch anytime you must need a really great battery backup on which you really can rely on. I find this device very useful as it provides
1) Huge backup plan: 20000mAh battery backup which can nearly charge my 4000mAh phone battery 3 times.
2) Portability: Very good while in travel as you won’t find every where charging points.
3) It has two USB outputs points+ 1 type C ouput points means we can charge three smartphones/ headphones etc . simultaneously very easily.
4) To charge power bank we have two options micro USB & type C port so we dont need a particular type of cable.
5) Allows type C to type C charging & recharging again the powerbank.
6) Supports fast charging.
7) Strong reliable powerbank.
Cons: 1) Not as such but a little heavy device to carry in pockets
2) Design is we can say a little old styled.
3) Price of Rs 1800 is a little high but only a little.
Overall I will give 4/ 5 stars based on my 4 months usage of this powerbank.
