Xiaomi 16000 mAh Power Bank Portable Charger Review

In today’s mobile world … smartphones and tablets are becoming thinner and more powerful, and so the battery capacity of these devices becomes a major concern for manufacturers. There’s only enough space for a small battery that offers limited capacity. So if you are a power user (ie always on your phone), the only way to compensate is to get yourself a power bank.

Thanks to my good old friend at the office, we’ll be taking a look at the Xiaomi 16000 mAh Power Bank Portable Charger. With a rated capacity of 16000 mAh, it’s the largest  power bank that Xiaomi has to offer, and comes with 2 USB ports which has a maximum output of 5.1V/3.6A.

What does all this mean? It means you can charge upto 5 x iPhone 6 (full charge), or equivalent to 2.5 x iPad Mini or 3.5 x Note 4. Now that’s pretty impressive!


It’s only a power bank … so what’s so special about it? Well, it’s not only about the Xiaomi power bank … it’s the story behind why I need one. There have been many times when I have ran out of juice on my iPhone 5S, which is notorious for battery life (the iPhone 6 is a bit better). So what do I do? Well, the only thing I can do is to invest in a decent quality and affordable power bank with enough capacity for at least 2-3 full charges … meet the Xiaomi 16000 mAh Power Bank Portable Charger.
