There’s no shortage of power banks that promise fast charging and big capacity. The problem is that most of them end up living at the bottom of your bag or worse, left at home altogether. Xiaomi’s 5000mAh 22.5W Ultra-Thin Magnetic Wireless Charging Power Bank takes the opposite approach. It’s built to be invisible until you need it, and that’s exactly what makes it compelling.
If you're tired of the bulk that comes with backup power, this is the solution for you.
Genuinely Ultra-Thin
At just 6mm thick and 98g, this is firmly in credit-card slim territory. Okay, maybe not, but you get the idea. Xiaomi claims it’s the world’s thinnest 5000mAh power bank, and based on the numbers, that holds up. In hand, it’s extremely light and barely adds bulk when magnetically attached.
That matters more than you think. A power bank that’s uncomfortable to hold while charging your phone is one you’ll stop using. This one stays out of the way, whether it’s snapped to the back of your phone or slipped into a jacket pocket.
The Glacier Silver finish keeps things understated. Clean, neutral, and very on-brand for Xiaomi.
Magnetic Wireless Charging (Or Wired)
This power bank supports Qi2 magnetic wireless charging up to 15W, which means fast, aligned wireless charging without fuss. The magnetic connection is strong and stable, designed to sit flush against compatible phones so it doesn’t wobble or block the camera while in use.
For iPhone users, this clearly leans into MagSafe-style convenience. For Android users with magnetic-compatible cases, it works just as smoothly. No cable management, no hunting for a port, just snap and charge.
And if you prefer plugging in, the USB-C port delivers up to 22.5W wired output, which is more than enough for quick top-ups on the go.
You also get support for simultaneous wired and wireless charging, which is useful if you’re topping up earbuds while your phone is attached magnetically. Small detail, but a practical one.
Capacity Expectations
Let’s be clear, 5000mAh isn’t meant to fully recharge modern flagship phones multiple times. That’s not the point here. This is a 'second battery' designed to get you through the end of the day, topping up from a low battery, handling navigation, streaming, or work calls when you’re out longer than planned.
Xiaomi rates the battery at 18Wh, which keeps it well within airline carry-on limits and makes it a safe everyday travel companion.
The advantage of this smaller capacity is control. Less weight, less bulk, faster recharging, and realistically fewer reasons to leave it behind.
Silicon-Carbon Battery Tech
To pull off this form factor, Xiaomi uses a high-energy-density silicon-carbon battery with 16% silicone content, paired with a large graphite cooling sheet for heat dissipation.
In plain English, that means more energy in less space and better temperature control while charging.
Who This Is For (and Who It Isn’t)
This power bank makes the most sense for commuters and city users who want emergency power without bulk, iPhone users looking for a slimmer MagSafe-style option, and anyone who hates carrying cables and chunky accessories.
If you’re after maximum capacity for multi-day trips or charging tablets, this isn’t it. But if you want something you’ll actually carry every day, it hits the mark.
Power Up Now
This isn’t the most powerful power bank Xiaomi makes, but it's definitely one of the coolest. By prioritising slimness, usability, and just-enough capacity, Xiaomi has created a backup battery that fits modern habits rather than fighting them.
It’s the kind of accessory you forget you’re carrying until you’re glad you did.
