Xiaomi 4i 10,000mAh Power Bank at ₹1,299: 22.5W Charging and the Trade-Offs
A 10,000mAh power bank is a practical middle ground for people who want emergency phone charging without carrying a large battery pack. Reliance Digital's product page showed the Xiaomi 4i 10,000mAh power bank at ₹1,299 when checked on 15 November 2026, against a displayed MRP of ₹2,499. The listing showed 48% off, free shipping and a one-year manufacturer warranty.
The lower live price changes the value calculation compared with older listings. Still, the number on the product page is only one part of the decision: check delivery to your PIN code, the final cart price and whether the charging profile suits your phone.

What does 22.5W charging mean?
The 22.5W figure is the maximum charging power advertised for supported charging combinations. It does not mean every phone will charge at 22.5W. The phone, cable and power bank must negotiate a compatible charging protocol and voltage/current profile.
If your phone supports a proprietary fast-charging standard, it may charge at a lower rate from this power bank than it does from its original wall charger. Check the phone manufacturer's supported input profiles before buying.
The product listing also names USB Power Delivery and Quick Charge 3.0. These are useful compatibility indicators, but they do not guarantee the maximum speed for every device.
How many times can it charge a phone?
The 10,000mAh label refers to the power bank's internal battery capacity under its rated conditions. It should not be read as 10,000mAh delivered directly to a phone. Voltage conversion, heat and charging losses reduce the energy that reaches the device.
For that reason, avoid assuming that a 5,000mAh phone will receive exactly two full charges. Actual results depend on the phone battery, charging efficiency, cable, operating temperature and whether the phone is being used while charging.
For occasional top-ups and travel-day backup, 10,000mAh can be convenient. If you regularly need multiple full recharges for a large phone, tablet or several devices, compare a higher-capacity model instead.
Port selection: useful flexibility, but check simultaneous output
The retailer's product title lists one USB-C input/output port and two USB-A ports, with three-device charging. USB-C can be used for charging the power bank and for output to compatible devices.
The important caveat is shared power. A 22.5W maximum should not be assumed to be available independently from all three ports at the same time. When multiple devices are connected, the power bank may divide or limit output. Check the printed specifications for the exact combined-output behaviour.
Is 280g too heavy?
The listed net weight is 280g. That is noticeable in a small sling bag or pocket, though manageable in a backpack, laptop bag or travel pouch. If you want a power bank for everyday pocket carry, compare lighter 10,000mAh alternatives and their output ratings.

- You need a guaranteed 22.5W output while charging multiple devices.
FAQs
Is the Xiaomi 4i power bank really 10,000mAh?
The Reliance Digital listing specifies a 10,000mAh battery capacity. Usable energy delivered to a phone is lower because voltage conversion and charging involve losses.
Does it support 22.5W charging on every phone?
No. Maximum charging speed depends on the phone, cable and compatible charging protocol. A device may draw less power.
Can it charge three devices at once?
The retailer's product title advertises three-device charging. The available output is shared and may be limited when multiple ports are used. Check the detailed output table on the packaging or manual.
Is ₹1,299 the current price everywhere?
No. ₹1,299 was the price displayed on the Reliance Digital page when checked on 15 November 2026. Prices, stock and PIN-code delivery availability can change.
What warranty is listed?
Reliance Digital lists a one-year manufacturer warranty. Keep the invoice and review the warranty terms supplied with the product.
Final verdict
At the checked listing price of ₹1,299, the Xiaomi 4i is worth comparing if you want a 10,000mAh power bank with a stated 22.5W maximum, USB-C and USB-A connectivity and a one-year warranty. Its limitations are equally important: 280g is not featherweight, charging speed is device-dependent, and the full 22.5W should not be assumed across multiple ports simultaneously. Buy based on your phone's charging compatibility and the final delivered price, not the MRP discount alone.
