₹3,299
20000 mAh is measured at the cell's 3.7 V; your phone charges at 5 V, and the conversion loses 30 to 35 percent, so what actually reaches the phone is closer to 13000 mAh -- about three and a half charges rather than five.
Full details →Who the Anker 555 USB-C Hub 8-in-1 PowerExpand Adapter is for
Buy it if: Anyone needing many ports at 1080p or 1440p, or 4K where refresh rate does not matter.
Avoid it if: Anyone driving a 4K monitor for daily work -- 30 Hz pointer stutter is genuinely unpleasant.
Who the Anker 325 Power Bank 20000mAh External Battery Pack is for
Buy it if: Travellers wanting several days of phone charging in something airline-legal.
Avoid it if: Anyone charging a laptop or wanting fast recharge -- 15 W in and out is slow at this capacity.
