1. there's fast charging available now but still the powerbank takes more than 7hrs to charge fully.
2. even though the output power is ~18.36W, it doesnt charge the phones faster.
3. the conversion rate is very less(~12000mah) compared to the actual capacity of the battery(20000mah).
4. the powerbank should have been compact in size.
5. the price is higher if it was around 1200-1300 then it would be an affordable one.

Great and genuine product and with a cool finish to top it up. This powerbank has a auto shutoff feature, so whenever the phone charges completely, the powerbank shuts off. Good feature as a power saving option.

Only couple of cons from my end. White color catches dust quite quickly and next is that this powerbank is heavy.. Like 400gms kind of.

Apart from these, I am very happy with this powerbank performance as it gives nearly 3 full charges for my Oneplus 2 3400mah battery.

Very good powerbank..its take a huge time to fully charge almost 12-15hrs..Once it charged it can be very usefull to charge mobiles.It is one of the best powerbank available in the market.Go for it !

Very nice product. I love Xiaomi Company. This company tries to make new innovation with low price. This power bank looks great, and I like its ship.

Nice power bank , blindly any one can buy

Great product

After 6 months of usage I'm writing this review. It disconnects the phone while charging sometimes. And don't expect it to charge your phone like the regular chargers(Mine is QC2 enabled charger.). U need to put ur phone to charge in the night so that u can get up with a happy smile. Buy the latest MI power bank 2, That chargers a lot faster than this. Tq. PS : The USB cable will after 3-4 months of usage.

Good product ,best in class ....
Pros:- High density battery.
Nice mechanism.
Support fast self charging
Beyond average build quality.
Mi authentication is good.
Cons:- can't charge phone fastly maximum is 1.7 amp/sec.
There is no 93% conversion rate in 5V 1A .

This is original product. This power bank charge my I Phone & Samsung J 7 twice
Normal charger take too long time. I charge the power bank full night but it's only 2 led light. If ur want fast charging of this power bank then use Turbocharger. It's delivered 2 amps output current. The design & led indication are useful.

It takes long time (>11hrs) to charge completely with a 2 AMP plug. Thats the only con. Once fully charged it lasts for a full week (mon-fri) and thats awesome. Need a 5 AMP plug for fast charging. Super design and charges mobile fast. Recommended !!!
