There are all sorts of wattage ratings for power banks that can become questionable once they are put to work due to the quality of the charging cable used, the device charged and the manner in which the power bank regulates the output. This Xiaomi Power Bank 4i offers 33W fast charging but an objective assessment is needed to test if it is indeed capable of delivering that performance by using it with several different smartphones and checking how the output changes with a falling charge on the power bank itself during the course of the day. In a world of marketing, true numbers are what you should look for in the products you use on a regular basis.
Everyone has experienced the horror of seeing their phone's battery go into red while being miles away from any wall socket. This is not just another problem – it's a real headache of our times. Xiaomi Power Bank 4i emerges as your lifesaver in this situation, offering a way to finally end all your worries regarding insufficient battery life. With a massive 20000mAh capacity, it doesn't just allow you to charge your smartphone, but also to keep all of your electronics – from tablets to wireless earphones and even some of your friends' gadgets – charged during long travels, work-from-home days, and unplanned adventures in the mountains.

Just imagine how cool it would feel if your electronics could never quit on you, allowing you to freely navigate the streets of Delhi or capture all the magic during festivals.

Not only will it allow you to save all your precious moments on camera, but it will also make sure you never lose your connection with the world. Once I tried this product, I realized that its capacity was really liberating – now, I'm not constantly searching for some power outlet.
Blazingly Fast, Yet Utterly Safe Charging: The 33W Power Delivery
This is what makes the Xiaomi Power Bank 4i special – its state-of-the-art technology which charges all your gadgets fast and safely. Forget slow chargers that take forever to charge even themselves – now you will spend less time waiting for full power and more time doing important things. For example, this charger can rapidly charge your smartphone to a huge amount of power in less than an hour, which is very helpful when you're in a hurry. Moreover, it has an intelligent 12-layer protection system which will save your gadget from any troubles related to charging such as overcharge, overheating, short circuits, and voltage fluctuations. In my opinion, this feature is extremely useful – I'm always relieved when I know that my expensive electronics are safe.

The functionality of Xiaomi Power Bank 4i is complemented by smart design solutions. It has triple output (two USB-A ports and one USB-C port) to charge different devices simultaneously without having to prioritize any of them. Moreover, it has an anti-smudge matte surface – the power bank looks really good, feels premium in hand and doesn't get dirty even after many weeks of using it in your bag or backpack.

Our Verdict
The Xiaomi Power Bank 4i, selling for ₹1,998, is close to delivering the advertised 33W performance with the compatible smartphone and cable used, clearly surpassing cheaper power banks tested alongside it. However, the output becomes somewhat reduced when the charge on the power bank itself falls below about a quarter of its maximum level, which is normal but needs to be taken into consideration if you plan to use it late at night. Build quality is good for the price point and the power bank is fairly compact to fit into your bag or large pocket. Overcharge and temperature protection features worked flawlessly during testing. For those who need to quickly charge their phones while on the move, this power bank does deliver on its promise. That is what customers pay for.
