As far as Zimbabwe goes, availability of electricity is very erratic. There are a bunch of power banks available locally thanks goodness but most of them have a bit of a problem. They say 10000mAh or even 20000mAh but only charge your phone once before they run out of juice. Worse off some take a whole day to charge your phone and if you use it while it’s charging the battery level in your phone stays the same.

But not all power banks are equal. The Mi power bank is compact and sleek with a confidence building metal shell. The more interesting part is it has been able to top up a phone 5 times before it was left with a bar of juice. As the cherry on top it supports fast charging both ways. This means if you have a phone that does fast charging it will charge your phone really quickly as intended by it’s makers. Gone are the days when you would take days to charge your power bank. Just give this one a fast charger and it will be full in just about 6.7 hours.

It’s literally the last power bank you will ever buy…unless we bring you an even bigger one.
