For any tech lover or frequent traveller, a power bank is a must-have accessory.
There are loads of models available, and the latest all support fast charging.
Other more specialised power banks can charge laptops, have USB-C ports, and support tech such as Qualcomm’s Quick Charge.
To help make choosing a power bank easier, we tested 10 models, from affordable to high-end with niche feature sets.
A big problem with power banks is that the actual battery cells and charging circuitry inside some lesser brands can be of low quality, and not actually provide the rated capacity. However, many power banks tested have batteries that (when new) are giving more than their rated capacity, which helps even it out.
How we tested
We logged the power produced on a static load. Due to efficiency losses, the output capacity will be up to 10% less than the rated battery capacity.
As a comparison, we also calculated each power bank’s ‘mAh per dollar’ score to help assess the overall value – higher is better.
