Xiaomi Power Bank 20000mAh Review
You can’t help but be impressed with the Xiaomi Power Bank 20000mAh. Packing a whopping 20000mAh, it is a powerful bit of kit. It’s also feature-rich. Coupled with dual USB ports and a USB type C port, it’s able to fast-charge all your mobile devices. Rounding off this excellent resumé, its stylish looks could easily justify a much higher price point. What’s not to like?
Charging technology
Mi (or Xiaomi) is an established cell phone manufacturer and has been producing an increasing number of power banks and accessories of late. The Xiaomi Redmin Power Bank 20000mAh we’re reviewing today is their most powerful, flagship portable charger.
When it comes to ports, this power bank features 4 of them: two USB A, one USB C, and a Micro USB. The USB type-A ports can deliver a maximum of 18W of power when used alone. They can also be used simultaneously, but in this case, their power output is slightly lower.
Both the Micro USB and the USB type C port are input-only ports. This can help the power bank charge faster, however, it would have been much better if the USB type C would be an output port too. A lot of different power bank models feature bidirectional USB type C ports, so it is somewhat of a disappointment the fact this one features an input-only port.
The Xiaomi Power Bank 20000mAh does take around 7 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 3.0 recharging.
Look and feel
The Redmi Power Bank 20000mAh continues to impress in the looks department. The black plastic body has a grippy surface – you’re not going to drop this! 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 are solid, and overall it feels very well put together. Mi has opted to use high-quality components which is very encouraging.
The Mi Power Bank 20000mAh is cased in grippy plastic, whereas their smaller capacity power banks utilize 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 6.06 x 2.9 x 1.07 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.
Pros
Can use either Micro USB or USB Type C for charging
2 x 2.1A outputs = fast charging
High quality components
Cons
Reported limited availability of stock
Long time to recharge
