Xiaomi Power Bank 4i 10000mAh 22.5W Fast Charging PD|Smart 12 Layer Protection| Durable Steel Casing |Triple Output Ports|Supports All Phone(MI Power Bank),Purple

Best powerbank with compatible size and easy to carry. The powerbank charges my iphone properly and fast charging is too supported.

Good, charges fast. Easy to carry. But the cord stopped working after about 2 months.

Ive been using this product for almost a week, and I needed it to charge my phone through lots of travel. And ofcourse, it helped my 5000mah battery phone charge in 1.5hrs( my phone kinda old). The compact powerbank fits in any pocket, and kinda made me look cool. It is really good, my dad wants to steal it from me. Lmao.

Good Quality. Takes a bit of time to charge, but a faster charging brick could solve that prolem

Very good product, worth buying !

I grabbed this one 'cause I used to have the 3i power bank 20k, and that thing was awesome! It lasted me a good four years. But this one? Nah, it's not great. You can charge a 5k battery phone like, one time, and that's it. It doesn't even give you an extra 30%.

The Xiaomi Power Bank 4i (10000mAh, 22.5W Fast Charging) has quickly become one of my most dependable everyday gadgets. It combines premium build quality with excellent performance, making it perfect for travel, daily use, and emergencies. 1) Portability This power bank is impressively compact and lightweight. Despite having a steel body, it’s easy to carry in a pocket or small bag. The slim design makes it ideal for commuting, long trips, or even keeping in your jeans pocket without discomfort. 2) Battery Backup The 10000mAh capacity delivers solid backup. It easily charges most smartphones 1.5 to 2 times depending on the model. Even with fast charging enabled, the backup remains consistent and reliable. 3) Battery Life The standby battery life is excellent. It holds charge for days without draining, which is something many power banks struggle with. Even after multiple charging cycles, the battery performance remains stable. 4) Performance The 22.5W fast charging is the real highlight. It charges phones noticeably faster than standard power banks. The PD (Power Delivery) support works great for compatible devices, and the output remains stable without heating issues. The 12‑layer smart protection system adds confidence by preventing overcharging, overheating, and short circuits. 5) Cable Quality The included cable is sturdy and well‑built. It supports fast charging properly and doesn’t feel flimsy like many bundled cables. The connectors fit tightly and don’t loosen over time. 6) Power & Efficiency The power output is strong and consistent. Whether you’re charging a phone, earbuds, or a small gadget, the power bank maintains stable performance. The steel body also helps with heat dissipation, keeping everything cool even during fast charging. 7) Final Verdict A premium, durable, and high‑performance power bank that delivers exactly what it promises. If you want something portable, powerful, and long‑lasting with reliable fast charging, the Xiaomi Power Bank 4i is an excellent choice.

It seems that the actual real use capacity is around 7500 to 8000 mAh. I never get 10000 mAh from a full charge. Otherwise the build quality and looks are quite good.
