Xiaomi Power Bank 20000mAh Review

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.

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

xiaomi redmi 20000 ports

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 the 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 darn 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.

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.

My Experience With the Xiaomi 20000mAh

What attracts me the most to this power bank is the overall design. I like that it has a feeling of luxury and elegance about it, even though the case is only made out of plastic. But the matte front and back, with the ridged sides and the glossy logo, really tie this piece together. This power bank gives me a similar feel to a tuxedo. 

With the 18W max output it can fast charge my smartphone just as well as any fast charger. This is great and I don’t feel any difference at all when I’m using the Xiaomi 20000mAh. 

However, where I have some beef with it, is when it comes to charging the power bank itself. First of all, it has dual charging inputs. This means I need to plug in two different cables in order to reach the maximum recharge speed. 

Then one of the input ports is a Micro USB, which is an increasingly outdated port. I would have much preferred to have a USB type C instead. The other one IS a type C, but it only has an input function! You cannot use it to charge other devices. 

In my view, this is a lost opportunity. Why not take full advantage of the functionalities that type C comes with and make it bidirectional? Dare I also say that it might be a USB type C that can output more than 18W, thus making the power bank more capable?

Alas, these are grievances of someone who has multiple other power banks to choose from and who uses them on a daily basis. But for non-power users, this could actually be a great choice even if it doesn’t have the latest thrills and frills when it comes to charging technology. Not to mention that it’s a great-looking piece too!

Final Thoughts

The Xiaomi 20000mAh power bank is more than just an accessory; it’s a useful and good-looking companion. It stands as a testament to Xiaomi’s ability to blend form and function seamlessly. Although there are more powerful power banks out there, if you’re not looking for something too fancy when it comes to charging technology, then the Xiaomi 20000mAh is a good choice.
