Power banks come in all shapes and sizes. Depending on your needs, you can choose either an ultra-slim device that attaches to the back of your phone or a large power bank that can charge your laptop and phone simultaneously at full speed. I, however, think differently. An ideal power bank for me should be somewhere in the middle. Something that can charge my laptop but is small enough to fit inside a backpack. Xiaomi seems to have listened to the demand and launched its new 67W 20,000 mAh Power Bank in India. I took it on a trip to Delhi to test whether you should spend ₹3,499 on it.
Design & Charging
The Xiaomi 67W power bank is more of a travel accessory. It’s made from plastic, of course, but it doesn’t feel cheap. The blue color feels like a breath of fresh air in a stale, black power bank world. The design is rectangular, so it’s easy to hold in your hand, and the dimensions are decent. I wouldn’t call it compact, but it fits in a bag pretty easily without taking up much space. On the side, you get a small display with a button directly underneath it. You press it to see the remaining charge, which is a nice touch. The front is where all the ports are. The most important one is the integrated Type-C cable, which doubles as a carrying strap and supports 67W of fast charging. You also get a USB-A port and another Type-C port to connect longer cables.
My experience with the power bank was pretty good. I was invited to an event in Delhi, which meant catching the morning flight, attending the event, and then coming back the same day in the evening. I carried my MacBook Air M1, whose battery health has seen better days, so I knew I’d need to charge it somewhere. The first leg of the journey went well, but by the time the event ended, my laptop was down to around 30%.
Since I can’t be bothered to look for a charging socket, I connected it to the Xiaomi power bank. With a fast cable, it charged my laptop from 30% to 60% in about 30 minutes. As for my OPPO Find X8, the power bank supports SuperVOOC, so it can fully recharge my phone in about 40-50 minutes.
The Xiaomi power bank is rated at 20,000 mAh, though the usable capacity is naturally lower due to voltage conversion losses. For context, it can charge my MacBook from zero to full just over one time, while phones can typically be charged more than twice. That estimate assumes a phone with a battery of around 5,500 mAh and not for ridiculous battery phones like the Redmi Note 17. If you use an iPad, you’d be able to charge it 1.5 times before the power bank needs to be plugged in. Speaking of that, the Xiaomi power bank supports fast 65W charging. You can charge it from 0% to 100% in about 2.5 hours.
Verdict
At ₹3,499, Xiaomi has made one of the easiest power banks to recommend in this price segment. It strikes the balance I was looking for: powerful enough to charge a 67W laptop, yet compact enough to fit in a backpack without feeling like you’re carrying a brick. The built-in USB-C cable is more useful than I expected. The display makes checking the remaining battery effortless, and the charging speeds held up well during a full day of travel. Sure, it isn’t the smallest 20,000mAh power bank around, but that’s a compromise I’m happy to make for the extra versatility.
