These 3 Xiaomi power banks give you all the power you need, when you need, and how you need

It is not every day that over here at India Today Tech, we get excited about new power banks. This is a fairly mature market. More significantly, given how phones have acquired bigger batteries and laptops have become more power-efficient, the need for a power bank too has diminished. Earlier, we all used to carry a power bank with us. Nowadays, most of us rarely do.

And yet a few weeks ago when I came across Xiaomi’s three new power banks I found myself impressed. Xiaomi, apart from being a brand we all know for its phones, is also the No 1 brand in the power bank market in India. Probably that has prompted the company to bring some new offerings. Irrespective of the reason, I am glad that it has brought to India three cool new power banks — Ultrathin Magnetic Power Bank 5000, Power Bank 20000 165W, and Magnetic Power Bank 10000.

These power banks have different designs and functionality. But their core technology is the same, which is supplying power to depleted batteries in a manner that is safe. They have gone through a nail penetration test, compression test, hot box test, and overcharge test. They are all flight safe. They all offer multiple safety features, including flame-retardant casing, and overcharge protection for both inbound and outbound current. They also, including the thin one with 5000 mAh capacity, support simultaneous charging for multiple devices.

But as noted, they are also different in how they go about their core job, which is supplying power. Let’s talk about them one by one, including my favourite that is the Power Bank 20000 165W. But we start with the thinnest and the smallest one.

Somewhat inspired by the iPhone Air MagSafe Battery, the Mi UltraThin is a very slim power bank. That is because it is meant to be attached to a phone’s back cover so that you can carry and use the device easily even as you charge it. It has a thinness of 6mm and weight of just 98 grams. It also comes in multiple colours, including orange in case you are thinking of pairing it with the Cosmic Orange iPhone. The three powerbanks have different sizes.

The thinness and weight make the Mi UltraThin a reasonably good option if you are hoping to pair it with a high-end phone that supports wireless charging. It also helps that the body of the power bank is made of sleek aluminium, although the part that attaches to the phone for charging has a fibre glass coating on it, soft and almost velvety to feel.

The Mi UltraThin is a minimalist power bank. Just like its design, its functionality too is fairly basic. It is essentially a wireless power bank with support for 15W fast charging, which means you will like to leave it attached to the phone when you are travelling or your phone is running low on juice. To speed up you can use the wired charging, though. There is one USB C port in the power bank, which can supply power at a rate of 22W.

There are four very tiny LEDs on the power bank to show you the status of the charging as well as the remaining battery. And then there is a multifunctional button. A single press on it when you are not charging anything will light up LEDs to indicate the remaining battery charge. The UltraThin Magnetic 5000 has quite a slim design.

A single press while charging toggles between multi-device support and wireless charging mode. Here is an example: You are carrying the charger snapped to your phone and then you also attach earbuds to it using the USB C port. In this instance, you can press the button once to activate or deactivate multi-device charging. In multi-device charging, the power bank supports 7.5W wired charging and 5W wireless charging.

The other mode is low-power charging mode, which can be activated by double pressing the button. In this mode, the power bank switches to low power, suitable for charging smartwatches and fitness bands etc.

The wireless as well as wired charging is reasonably fast, but is not in the league of what bigger power banks can offer. Also, the capacity of 5000 mAh means the Mi UltraThin is good enough for one to two days of use if you are actively using it to prolong the battery life of your phone.Mi Magnetic Power Bank 10000

Of the three power banks, this one is the most regular one. In both functionality as well as its design. It is also the kind of power bank that is jack of all and master of none. As the name suggests, there are batteries — two of them — totalling around 10000 mAh in total charging capacity.

With more charge inside it, the Magnetic Power Bank 10000 is also bigger and heavier compared to the thin one. But it is still small enough that you can carry it attached to your phone, which it does via magnets while wirelessly charging the device. But unlike the thin one, which remains pocketable while it is attached to a phone, the Magnetic Power Bank 10000 is more of a table accessory when your phone is connected to it. The Magnetic Power Bank 10000 sits in between the UltraThin Magnetic Power Bank 5000 and the Power Bank 20000 165W.

This power bank too offers both wireless and wired charging. For wireless charging, Qi 2 standard is supported, which is nice to see. Also the wireless charging speed is more than reasonable at 25W. The wired charging, meanwhile, supports speed up to 45W through its USB C ports. There are two of them, one via the attached cable, with another one being an open port.

If you use only one port, you get a full 45W charging speed. Using two of them simultaneously reduces speed to 15W each. The wireless charging by default is switched off if you connect the power bank to a device in wired mode. To switch it on and simultaneously charge a wireless device, users need to press the multi-functional button twice.

Talking of the button, it can also be pressed once to light up four tiny LEDs and display the remaining battery in the power bank. Just like the UltraThin, this one has been tastefully designed with its rounded edges. Although, it doesn’t use aluminium. Instead, it uses a soft silicon casing, which feels premium to touch and looks tastefully minimalistic in white colour.Mi Power Bank 20000 165W

As the name suggests, and the images show, of the three power banks this one is the biggest. And heaviest by far. It is also a charger that doesn’t support wireless charging. Yet, it is my favourite of the three.

The reason is easy: the Mi Power Bank 20000 165W is a multi-functional power bank. It is meant to charge not just phones, but almost anything that is portable. And it is supposed to charge everything fast with its charging speed of up to 120W. The Power Bank 20000 165W has the largest capacity of the three.

But what about 165W? That is because the 165W bit in the name comes from the power bank’s ability to charge two devices simultaneously at the peak speed of 120W and 45W. In other words, perfect for charging a laptop and a phone at the same time.

Unlike the two other power banks in the lineup here, the Mi Power Bank 20000 165W has a more utilitarian design. It is heavy and decently large. It’s not a pocket device, instead it is a proper travel charger that is meant to be used when you are going to be away from a power socket for several days, or when you must have means to charge your laptop on the go. But irrespective of its utilitarian design, it is built extremely well. And it has a braided and flat cable attached to it that feels equally durable.

There are three ports here: two USB C ports, with one via attached cable, and one USB A port. It also has a small display on the front, on which you can cycle through by pressing the integrated button. It shows the amount of charge remaining and charging speed when one of the ports is engaged. Using the button — double press — you can also toggle the low power mode for those instances when you are charging something smaller, like a fitness band.

Now, the reason why I particularly like the Mi Power Bank 20000 165W is because this is a power bank designed to function when you really really need juice. And given its charging speed and the size of its battery, it is also a charger that you can use with multiple devices. Or rather, anything portable has a battery inside it.

Some days I travel out of the city and head to nearby forests and hills to do photography. It is on occasions like these where I believe the Mi Power Bank 20000 165W would serve its users best. Not only can it keep the phones and laptops going in the wilderness, it can also keep the cameras and other electronics going. For example, I use a charging case from Neewer for the extra batteries that I carry for my DSLR. That case and the Mi Power Bank 20000 165W are match made in heaven. I mean you get the idea.

Just to sum it up: I found all three power banks well-made and functional. But they also have different use cases. Pick the one that will suit your use case. The Mi UltraThin is the perfect pick if you want to carry your charger attached to your phone on a day-to-day basis. The Magnetic Power Bank 10000 is a little bit of everything, perfect for leisurely travels or just as a backup option that you can carry always in your bag. The Mi Power Bank 20000 165W, meanwhile, is for those who go off the road, sometimes for days at stretch. It is heavy, functional, and meant as a heavy-duty backup.

Xiaomi sells the Mi UltraThin at a price of Rs 5,599, the Magnetic Power Bank 10000 at a price of Rs 3,699 and the Mi Power Bank 20000 165W at a price of Rs 4,999.- EndsPublished By: Armaan AgarwalPublished On: Sep 23, 2026 08:09 ISTAlso Read | Redmi Note 17 Pro review: Stylish package with a massive batteryAlso Read | Google Pixel 11 Pro Fold review: In a class of its ownAlso Read | Haier M70 Mini LED TV 65-inch review: Bright display, powerful sound and value for money
