This become like my daily use to carry along with me where ever i go and if i place full charging until 4 led lights got blinking it will be used for my all smart phones to charge for min - 6 times and form this charging also happening very quickly

Good to recharge a 3000mah battery (LG G2) for 2.5 times from 10 to 100%. ideally it should have been 3 times, so I can only say its good but not excellent.

Mi 10400 mAh Power Bank
good and comfortable for all mobiles
giving good backup
the product cost only Rs 999/-
when compared to other brands its very good ......!

It solved my purpose. It is sleek and sturdy metallic body. A bit heavy but have enough juice to charge 4 phones and that too fast!! One thing, the device itself takes lot of time to charge itself. Charge with a normal Mi Phone Charger, then its faster, but with the cable given, it will take ages.

Overall Satisfied with the Product!!

Great product, reasonable rate and good performance by MI Powerbank. It is recommended by me to all to go for only MI powerbank. Really good.

Hi All,

I think hands-down this is the best utility product that you would buy. Infact, I never thought of this in the past. But then when it came out, I was thrilled.

I have used the Sony one when it came out with capacity of 1500/2000/2500maH ranges. This is one of the best and helps in charging my Samsung-Note3 phone atleast 2-3 times completely.

Features - 4.0/5
Appearance - 4.0/5
Quality - 4.5/5

I love Xiaomi Products, so i may be a little biased on them.
It is an awesome power bank, charges my 2000mah phone 4 times, before it goes dead, though it is less than the claimed efficiency of 90%, it is still enough for me.
I have Xiaomi 2A charger and it gets charged in 5hrs.
though after almost 4 month of usage, I can feel that the performance is degrading, though not very much.
Awesome build quality, never thought that for 1000bucks, I'll be getting product of aluminium build.

Not much Satisfied with the product. But would say that product is good. Charging is faster than phone charger.
Problem -> Sometimes light indicator would not work properly and shows wrong lights. But again i guess these problem is with my product. Not all the product are same.
So, I would say these is best power bank in the very low cost. Just go for it.!

The piece was pretty cool n good battery life, But power bank takes more than 20hrs to get fully charged .consumption of charge totally depends on the mobile you use for example , it charges my lumia 520 of 1430mah for 6 times and xperia P of 1305 mah not even 2 times,

Power Bank output is pretty awesome but what it lacks is it takes 10-12 hours in recharge. 10400mah is perfect option those who are looking for good power bank
