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:

  • 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 charge simultaneously, 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.

Note: We removed the "total number of charges" element of our test as we felt it had become arbitrary with the huge range of phones on the market. You can calculate the approximate number of charges yourself by dividing the usable measured capacity of the power banks you're considering by your smartphone's claimed battery capacity.

    Each power bank is connected to an electronic load reference instrument, which is set to draw the maximum supported current from the fastest charging USB-A port. The voltage is determined by the power bank itself and recorded in the output, and data is graphed to show capacity drain over time. This gives us the total milliamp hours that the battery supports.

    Can power a laptop via USB-C

    Expand to view more details.

    Some USB-C enabled power banks can power USB-C enabled laptops using a USB-C to USB-C connection. This means the laptop battery will last longer as the power bank is essentially operating as a second battery. Charging is different to powering, as it replenishes the battery during use or when it's off. Power banks in this test can't charge laptops, but some can power laptops. If the laptop didn't indicate that it was on battery power, then we determined that the power bank on test couldn't power it.
