Rank #2 in Best 10000mAh Power Bank 2026: 8 Ranked, and the Numbers That Do Not Add Up
INIU 45W Power Bank 10,000mAh with Detachable Cable
Price and rating as shown on Amazon when we collected them. Both change.
The INIU 45W Fast Charging Power Bank, model number P41-E2, is the runner-up in our guide to 10,000mAh power banks. It is £18.64, rated 4.5 out of 5 from 80,863 ratings, and the listing describes a 10,000mAh cell, three ports (two USB-C and one USB-A), LED indicator lights and a 12cm detachable braided USB-C cable that ships attached to the body rather than as a separate loose lead. It is sold on size as much as on power: the first bullet claims the TinyCell battery makes it 40% smaller and 36% lighter than conventional chargers of the same capacity.
What puts it at number two is that it is the listing in this group where the headline and the spec table pull against each other. The title, the second bullet and the feature list all say 45W. The same listing's spec table says 12 Volts and 3 Amps, and 12 x 3 is 36W, not 45W. The weight is split too: Item Weight is given as 182g while Battery Weight is given as 160g. Two different sets of dimensions appear as well — 13.4 x 6.9 x 1.3cm and 11 x 6.9 x 1.7cm — and the power source is listed as Corded Electric on a product whose selling point is being carried onto a plane. Everything on this page is taken from the Amazon listing; we have not tested the unit ourselves.
