Portronics Luxcell B 10K 10000mAh 22.5W Fast Charging Ultra Slim Power Bank, USB-A + Type C PD, Wake Up Button (Green)

We keep this Portronics power bank because the rating history (4.0★, 3,700) clears a 4.0 floor at ₹881. A thousand-plus ratings is a usable sample at this price. Still read a few recent 3-star reviews for the actual trade-off.

Printed mAh is before conversion loss. A 20,000mAh pack does not pour 20,000mAh into the phone. Prefer BIS-marked charging gear. Check whether this pack can actually fast-charge your phone’s wattage, not a generic USB claim.

The title leans on fast charging, power bank. Treat those as claims to verify on Amazon — we rank rating history, not a lab test of each word. 5W is a ceiling. The brick, the cable, and the phone all have to agree or you get slow heat, not fast charge.

10,000mAh on a box is a ceiling. Real runtime depends on the screen, 5G, and heat. Reviews that mention a full commute are more useful than the printed number.

Among 32 listed gadgets (₹129–₹2,449), 72% of the gadgets we list cost less than this. About 31% of peers here have fewer ratings.

At ₹881 in gadgets, pay for the failure point of the category — zippers, grip, warranty split, compatibility — not for the lifestyle photo. If a cheaper sibling has a much larger rating sample, read both before you stretch.

This page is a guide, not a shop and not a lab test. You buy on Amazon.in. Confirm seller, GST invoice, India warranty or return window, and the live rupee price there — if the number here disagrees, trust Amazon.
