The battery life of your smartphone is under a lot of extra strain from apps, social media, music streaming and online video. A power bank will help keep your phone charged throughout the day whether it's an iPhone or Android with a micro-USB or USB-C input.

We test power banks designed to keep even the most power-hungry smartphones kicking day and night. Our detailed test reveals:

  • the number of times they can charge your phone before they need charging 
  • approximate charge time
  • approximate portable battery recharge time
  • size, weight and which models can fit in your pocket.

Our interactive comparison table shows the number of devices each power bank can simultaneously charge, whether they can power a tablet, laptop and Nintendo Switch, and other useful features and functions such as auto on/off settings, fast charge and USB-C output.

Shopping links on the CHOICE website

CHOICE is an independent, nonprofit organisation dedicated to helping consumers. Clicking a link will take you to a retailer's website to shop. While we make money if you buy through some retailer links, this doesn't influence any of our rankings. 100% of the money we make goes straight back into our nonprofit mission. We're currently testing this service and will consider providing more shopping links in the future. Tell us what you think.
