Design & Build Quality
The Xiaomi 4i comes with a clean and minimal design that feels modern and practical. It is slim enough to carry inside a backpack or even a large pocket without feeling bulky.
The outer casing feels sturdy for a budget power bank. The LED indicators clearly show the remaining battery percentage, and the power button works smoothly.
For everyday travel and office use, its compact size is definitely a plus.
Charging Speed & Real-World Performance
This is where the Xiaomi Power Bank 4i stands out from regular 10W models.
With 22.5W fast charging support, it charges compatible smartphones noticeably faster. During testing:
• A 5000mAh smartphone charged approximately 1.5 to 1.8 times
• Fast charging worked properly with supported Android devices
• iPhones also charged efficiently using the Type-C port
When charging three devices at the same time, the speed reduces slightly — which is normal for most power banks in this segment.
Overall, performance is reliable for daily backup needs.
Actual Battery Backup & Efficiency
Although it is rated at 10000mAh, the usable capacity is lower (as with all power banks due to voltage conversion).
You can expect around:
• 6000–7000mAh effective output
• Stable charging without sudden disconnection
• Consistent energy efficiency
For a single-day backup or emergency use, it performs well.
Safety & Battery Protection
Battery safety is extremely important when choosing a fast charging power bank.
The Xiaomi Power Bank 4i includes 12-layer advanced protection, covering:
• Overcharge protection
• Short circuit protection
• Temperature resistance
• Over-voltage protection
• Over-current protection
Even during fast charging, the device did not heat excessively in normal room conditions. That adds confidence for long-term use.

Who Should Buy Xiaomi Power Bank 4i?
