Converting cells to USB output loses roughly a third, so a 10,000mAh unit delivers about 6,500mAh to your phone—around one and a half charges for a typical 5,000mAh handset.

Xiaomi Power Bank 4i 20000mAh 33W – ₹1,999
This is the pick of the lot.
It usually sits around ₹2,060, dipped to ₹1,579 last October, and has spent most of the past year between ₹1,900 and ₹2,300.
At ₹1,999, you're buying slightly under the running price, not at a once-a-year floor.
But 20,000mAh at 33W for under two thousand is a fair deal on any day.
The catch is weight. This is a bag power bank.
If you want to pocket it, look at a 10,000mAh instead.
Xiaomi Power Bank 5i 20000mAh 67W – ₹3,299
No major discount on this one.
It launched on 28 July at ₹3,299 as an introductory price against a ₹3,499 regular price, and the sale hasn't moved it.

Still a good buy if you need what it does, and the bank offers are where your saving comes from here.
It's the one to get if you're keeping a laptop alive.
67W covers most thin and light notebooks, there's a cable built in, and 20,000mAh will do a phone three times over.
