We test more than 30 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 (USB-A, USB-C and fast charge)
  • 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, as well as 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, non-profit 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 non profit mission. We're currently testing this service and will consider providing more shopping links in the future. Tell us what you think.
