Xiaomi Power Bank 20000mAh at a glance

You can’t help but be impressed with the Xiaomi Power Bank 20000mAh. Packing a whopping 20000mAh, it is a powerful bit of kit. Its also feature rich – how about the ability to charge your 12″ Mac Book 1.2 times!? Yes you heard right! Coupled with dual USB 2.1A outputs it will charge your devices quickly. Rounding off this excellent resumé, its stylish looks could easily justify a much higher price point. What’s not to like?

Capacity & Charging speed

Mi (or Xiaomi as it is known in China) is an established cell phone manufacturer and has been producing an increasing number of power banks and accessories of late. The Xiaomi Power Bank 20000mAh is their most powerful, flagship portable charger.

Perhaps the most noteworthy feature of the Xiaomi Power Bank 20000mAh is its capacity to charge the new 12″ Mac Book via USB Type-C charging. This is a unique feature, and if you own the Macbook it is justification enough for the purchase. To take advantage of this feature you will need an appropriate USB Type-C cable, such as the Anker USB-C to Micro USB Cable.

Continuing on the good news is the Mi Power Bank 20000mAh ships with two 2.1A USB outputs. Two USB outputs means you may charge two devices at once. Whereas many power bank manufacturers will have one fast output port, and one slower, Mi has gone for 2.1A for both ports. Which in turns means super-fast charging for both ports!

The Xiaomi Power Bank 20000mAh does take around 12 hours to fully charge its batteries, but to be honest this is not surprising at all, given its huge power capacity. However, the Mi Power Bank 20000mAh does support Quickcharge 2.0 recharging. If you purchase a compatible wall charger such as the Aukey Quick Charge 2.0 Wall Charger your recharging time will be drastically shortened!

Look and feel

The Mi Power Bank 20000mAh continues to impress in the looks department. The white plastic body has subtly raised dots – which gives it a fantastic, textured feel. As well as providing a really grippy surface – you’re not going to drop this! The textured surface catches the light very nicely, and is offset by smooth plastic on the narrow edges.

Four LED lights on the business end of the unit indicate charge level, and the power button on the right side has a nice solid feel to it.

They’ve even paid attention to the Micro USB connector cable – which has a flat cable design. Just like Beats headphones cables, this is designed to make tangled cables a thing of the past. It looks pretty darned cool as well.

Overall this is a great looking piece of equipment!

Durability & Construction

The fit and finish of Xiaomi Power Bank 20000mAh impresses, and overall it feels very well put together. Mi has opted to use high quality components, for instance batteries by Panasonic and LG. Also the USB power control and charging chips are made by Texas Instruments. All of this is very encouraging.

The Mi Power Bank 20000mAh is cased in textured plastic, whereas their smaller capacity power banks utilise anodized aluminum. Some of you may prefer your power banks to be encased in metal for durability’s sake, but this would be offset by a heavier power bank.

Portability

There is no getting around the fact that the Xiaomi Power Bank 20000mAh measures 5.9 x 3.8 x 1.1 inches. So for portability that means you’re not walking around with this thing in your pocket! But if you look at the product images you will see that it comfortably fits in your hand. Its dimensions are also on par with other manufacturer’s 20000mAh power banks. So the Xiaomi Power Bank 20000mAh gets great marks here once again.
