Our process
How do we choose our picks?
We don’t lab-test products ourselves. Instead we synthesise current Amazon UK listings and published specs into clear, honest recommendations. We earn a commission if you buy through our links, but that never changes which products we rank.
Current UK availability
We check each pick against live Amazon UK catalogue data rather than last year’s model lists. Stock moves fast, so a listing can sell out after we publish.
Published specs
We compare manufacturer specifications so each pick is right for a real budget and use-case.
UK-specific fit
We factor in UK voltage and plug/fitting standards — details that generic global lists miss.

Editor's Note
Every listing here states its capacity in mAh, but only the Anker Prime and VEGER listings also give a watt-hour figure. Charging-time claims come from the brands; the Anker Prime listing says its figures are based on internal lab testing and actual performance may vary.
Our Take
The Anker Prime is the default pick for its stated 20,100mAh (72.36Wh), 220W total output, 140W laptop charging and 24-month warranty. For a pocket-size portable charger choose the VEGER, which lists 116 x 72 x 16.8mm, 180g, two built-in cables and a 3-year warranty, or the Anker 25,000mAh for the most stated capacity with built-in USB-C cables.
